Copper and iron vitriol application. What is the difference between copper sulfate and iron sulfate? What is ferrous sulfate: composition and properties

In the fall, gardeners begin to prepare their summer cottages and backyards for winter. For pre-winter processing of trees and shrubs, as well as soil in vegetable gardens, long-known inorganic substances are used - iron and copper sulfate. How do these preparations attract experienced growers? Will it be beneficial or harmful in horticulture or viticulture? How safe is their use for human health? Many novice gardeners are looking for answers to these and other questions. We will try to help them with our advice and recommendations.

Preparing plants and soil for wintering

After the entire harvest has been collected in the gardens, and the vegetables from the beds have migrated to storage in cellars and basements, it is time to prepare plants and soil for the winter period. At this time, gardeners will have to perform a variety of work:

1. Collect fallen leaves, burn it if there are trees and shrubs infected with fungus or other diseases.
2. Dig up the beds in the gardens, at the same time determine whether there are larvae or adult insects in the soil - pests.
3. To carry out the treatment of diseased plantings or the prevention of healthy ones, using various remedies for this. We must also not forget about the pests that have chosen places for wintering in your garden or in the garden soil.

There are many organic and chemical agents that can effectively fight harmful insects, destroy traces of fungal and other diseases, and prevent infection of healthy trees and shrubs. Let's take a closer look at how conventional iron and copper sulfates help in this.

The use of ferrous sulfate

Ferrous sulfate, or, in everyday life, ferrous sulfate is a fine-crystalline powder of blue or green color, according to its properties it is defined as a low-toxic, non-volatile and rapidly dissolving drug. Without harm to humans and the environment, it can be used in horticulture and viticulture:

inkstone

• for the treatment and prevention of fungal diseases;
• an increase in the iron content in plants (with chlorosis);
• to protect plantations from diseases such as septoria, scab, black spot;
• disinfection of damage to tree trunks.

Attention! Iron sulfate is not intended to fight insects and rodents, does not stimulate plant growth.

Method of application and dosage of ferrous sulfate

To process the plant and the soil around it, dissolve the powder in water in different dosages:

• 3% solution is used for spraying shrubs and young trees;
• 5% solution is intended for processing mature trees;
• 6% solution will help get rid of lichen and moss on the bark.

Council. To prevent the agent from getting into unwanted places, for example, on the gardener himself, the solution should be sprayed in calm, calm weather.

A strong solution (from 6 to 8 percent) can be used to disinfect walls (wooden partitions) of winter storage facilities, cellars and basements; a 10 percent solution is also used to disinfect street toilets and eliminate unpleasant odors.

It is necessary to follow basic safety rules, use goggles, a respirator and special clothing.

Tree processing

When digging a garden in autumn, it is recommended to bring powder crystals directly into the soil, this will serve as a good fertilizer and a guarantee of a future abundant and healthy harvest. For one square meter of soil, only one matchbox is required, or 10-20 grams of powder.

The use of copper sulfate in horticulture and its differences from ferrous sulfate

Copper sulfate is a powdery substance of blue crystals, by its properties it is a moderately toxic, rapidly dissolving substance, non-volatile with a barely perceptible specific odor.

Along with iron vitriol, it is successfully used in the care of fruit trees, shrubs and grape shoots. Has properties similar to ferrous sulfate and performs similar functions.

Copper sulfate

There are some functional differences between iron and copper sulfates:

1. For whitewashing, that is, protecting the root section of the tree trunk, iron sulfate cannot be added to lime, copper sulfate performs this function.
2. Copper sulfate is also involved in pest control, not iron sulfate.
3. In the form of top dressing, you can use both types of funds, but first you should determine the amount of each substance in the soil, that is, if there is not enough copper - add copper sulfate, respectively, with a lack of iron - iron.

Attention! Chemicals have a negative impact on our environment, and when using them, the rules specified in the Instructions for Use must be followed and strictly followed. Don't forget to read the recommendations if you are dealing with chemicals for the first time.

The use of vitriol in vineyards in autumn

Solutions of copper and iron sulphate are successfully used in vineyards and private horticultural vineyards. Their use in the fall contributes to:

• the elimination of many diseases that have struck the vine during the summer;
• death of pests hibernating on leaves, branches and root areas;
• enhancing the viability of the plant in winter due to the supply of the necessary microorganisms.

Spraying should be carried out after harvesting and abundant leaf fall; in the vineyards at the same time, young shoots unsuitable for wintering are pruned.

Prepared solution

For processing, a 10% solution of sulfates is used, that is, 0.1 kg of powder is used for 10 liters of liquid. Immediately before processing, the concentration of the resulting mixture is checked by dropping an iron object (a nail, wire) into it; it should not change its color. If the object does change (red or brown tint), then the concentration must be reduced by adding more water.

Council. Try to process the grape bushes before wintering, in the spring it will be much more difficult to get rid of diseases and pests, since with the arrival of spring, the sap begins to move in the plants, and with it the destructive effect of the disease lurking in the fall spreads, which can lead to the death of the entire plant.

Let's not deceive ourselves, any chemical agent brings not only benefits, but can harm our health. Try to follow all the manufacturer's recommendations specified in the instructions, do not use expired and questionable substances. By following all the tips and observing safety rules, you will protect yourself, your loved ones and the environment from possible harm. Be healthy and have an excellent harvest!

Many people know that iron compounds are one of the most effective (and, most importantly, inexpensive) means of combating mold and fungus, since if not construction, then almost everyone is engaged in repairs. However, this is not the only area of \u200b\u200bapplication of copper and iron sulfate. Experienced summer residents prefer them to numerous store-bought fungicides.

The advantage of these powders is that they are used more widely, and not only for eliminating lesions of garden vegetation by rot, scab, moniliosis and a number of other diseases. They are no less effective as disinfectants, and are also often introduced into some types of soils as a mineral supplement.

However, not everything is so simple. There are differences between iron and copper sulfate in some properties, specific use and a number of other parameters, which is quite understandable, given the differences in their chemical composition. This is what inexperienced summer residents overlook, believing that their scope in gardening is completely identical. Therefore, it is important to know which powder to use and for what purpose.

inkstone

Its blue crystals with a slightly greenish tint contain approximately 55% of the active substance.

Technical specifications for products - grade, chemical composition and a number of other features of ferrous sulfate or its sulfate (common names of this powder) - are detailed in GOST No. 6981 of 1994. By the way, it is referred to as iron (II) sulfate heptahydrate.

Features of the tool

Typically sold in 200g and 250g sachets.

The use of ferrous sulfate

Top dressing of the soil

Iron is one of the most essential chemical elements for plants. By introducing it into the soil, you can increase the yield of crops, "revive" old or withering trees and shrubs, in a word, give a new impetus to the development of garden plantings.

It is recommended that during autumn work on the site, add iron sulfate to organic fertilizers, which are scattered over the territory before starting to dig the soil. This is especially important for fruits and berries, as well as a number of ornamental plants. For example, currants, gooseberries, roses. During the winter period, not without the help of melt water, the earth is saturated with iron to a sufficient depth. In this form, the root system of flora representatives is much easier to absorb it.

On a note!

The use of ferrous sulfate as a top dressing is a very delicate issue. The dosages indicated on the packages are approximate and are only recommendations. It is necessary to take into account not only the characteristics of the soil on the site, but also the type of vegetation, the appearance of one or another representative of the flora. Perhaps there is enough iron for him in the soil, and the reason for faded foliage (poor yield, small fruits) is completely different. Therefore, the consultation of a specialist on this item will definitely not be superfluous. Especially when you consider that the autumn use of chemicals is highly undesirable.

Destruction of pests

A 5% solution kills not only insects, but also their larvae and egg laying. Iron sulfate is recommended for spraying garden plants, and as an additive to whitewashing, with which the trunks are treated. Desirable in autumn and early spring.

Unfortunately, not all sources indicate the peculiarity of the preparation of the whitewash composition. Mixing ferrous sulfate with lime, which is mainly used by summer residents, is undesirable. If it is decided to use this particular powder for prevention, then you need to whiten trees and shrub trunks with a special tool. It is often called garden paint. Not in short supply, and inexpensive.

Fight against plant diseases

Experienced gardeners use ferrous sulfate not only in fact, that is, when identifying lesions, but primarily as a prophylactic agent. It is effective against black cancer, fruit (gray) rot, scab, powdery mildew. And this is not a complete list of all the ailments that iron vitriol can cure. It is also used to get rid of vegetation and a garden plot from lichens, mosses.

Prevention (elimination) of chlorosis

Such a specific disease of horticultural crops is the result of a lack of iron elements in the soil. By introducing this powder into it, the owner of the site restores the ecological balance, thereby increasing not only the productivity of plants, but also their immunity.

Disinfection of places of mechanical damage

Unfortunately, trees and shrubs are susceptible to them, not only from careless handling of garden tools. For example, pruning, which is systematically carried out on the site. In addition, birds, constantly looking for insects on the trunks and under the bark; strong gusts of wind breaking branches. Treatment of lesions with iron sulfate promotes rapid wound healing.

Surface treatment

Iron vitriol is an effective remedy used by gardeners for disinfection, various mini-warehouses and storages. Ceilings, walls and even floors are treated with its solution. This ensures that mold and mildew are unlikely to grow in that confined space.

Approximate dosages of ferrous sulfate

For those gardeners who did not buy it, but took it from someone, approximate data on the concentration of the powder may be useful (in%).

• Spraying, whitewashing - 8 - 10.
• Fight against black spot - 0.3.
• Prevention against scab, black cancer and a number of other diseases - 5.
• Processing of walls, ceilings of storage facilities - 5 - 7.

If the plants are in the growing season, then regardless of the goals that the gardener pursues, using ferrous sulfate, the maximum powder concentration is 1%, no more. Do not forget about this.

Copper sulfate

Unlike the iron "analogue", the assortment of this powder is larger. It differs in brands (A and B) and grades (from the second to the highest). TU for products is established by GOST No. 19347 of 1999. The percentage of the active chemical element in copper sulfate is not more than 25%.

The color of copper sulfate granules is from blue to blue.

Feature of the tool

• Copper sulfate is poisonous (hazard class 3), although not everyone knows about this, and some simply neglect such information. Therefore, in the process of applying the powder, special care must be taken. First of all, exclude the possibility of getting the drug in the eyes or on the mucous membranes.
• It is used not only in its pure form, but also as a component of other formulations. On the basis of copper sulfate, Bordeaux liquid known to most gardeners and a number of other mixtures are prepared.
• One of the features of the drug is that the appropriateness of its use for solving certain problems is largely determined by the season. In spring, a solution of copper sulfate is used, as a rule, for spraying plantings, in autumn - as a top dressing applied to the soil. In the summer, few gardeners work with copper sulfate. Only when it is necessary to treat plants when a so-called root cancer is found, which most often manifests itself in seedlings.
• The preparation of solutions based on copper sulfate in metal containers is not recommended!
• This drug has a shelf life. Before use, this should also be taken into account. In practice, gardeners often simply increase the recommended concentration of copper sulfate solution if the storage period indicated by the manufacturer has expired (this is done, of course, within reasonable limits).
• The toxicity of the product causes some difficulties with the disposal of unused formulations. Moreover, in a suburban area, where, with rare exceptions, there is no centralized drainage system. That is why it is advisable to prepare preparations based on copper sulfate in the amount necessary to solve the problems facing the gardener, and not more.
• It is forbidden to mix copper sulfate with any other pesticides! By the way, not all gardeners know this.

It is sold in sachets with a capacity of 100 to 300 g or bottles (from 50 ml).

The use of copper sulfate

Fighting rot

This drug is well known as an effective means of preventing and killing mold and fungal diseases. Gardeners use it in areas for the treatment of country houses, outbuildings and various structures located on the territory (gazebos, benches, pool bowls), as well as, if necessary, soil. If we are talking about soil mixtures that are in appropriate containers (containers, boxes) located in greenhouses, greenhouses, outbuildings, then copper sulfate is simply irreplaceable when disinfected.

Destruction of garden pests

Copper sulfate is advisable to use for spraying plantings with the onset of warm days. The drug allows you to almost completely rid the area of \u200b\u200boverwintered pests and their larvae (under the bark of trees, in the trunk circle, in hollows, etc.), as well as fungal spores.

Preparation of mixtures

Several formulations are used in horticulture, but two are best known in the private sector.

Bordeaux liquid. It is obtained by mixing solutions that are prepared separately. Based on the bucket, you will need 100 g of copper sulfate and slaked lime.

Burundi mix. First, copper sulfate (100 g) is diluted in 0.5 buckets. In parallel, in the same volume of water - household soap (40 g) and soda ash (90 g). At the final stage, diluted vitriol is gradually added to the second solution, while constant mixing is performed.

Perhaps these are the main areas of application of copper sulfate in gardening. Top dressing of the soil is carried out, as a rule, where it is necessary to obtain thick, succulent grass for agricultural animals. And in other cases it is not used as intensively as ferrous sulfate.

Approximate dosages of copper sulfate

Values \u200b\u200b- in%

Spraying

• Fruit trees - from 0.5 (cherry, apricot, sweet cherry, plum and other stone fruits) to 1 (apple, quince, pear).
• Berry bushes - 1.5 liters (1%) for each. But only if we are talking about currants or gooseberries. Copper sulfate is not recommended for spraying other berry bushes!

Disinfection of seedling roots - 1

They are immersed in a container with a solution of copper sulfate for 2 - 3 minutes.

Treatment

• Soil - 0.5 (based on 1.8 l / m²).
• Planting material (seeds, bulbs) - 0.2.

Fight against plant diseases - 0.5.

It remains to add that neither copper nor iron sulfate is a panacea. Therefore, you should not expect that their use gives a 100% guarantee. If the result from the use of solutions in some case turns out to be lower than expected, then other drugs should be tried. An important factor is the correct determination of the processing time. It is not entirely correct to focus only on various calendars for summer residents, since they contain generalized information. The vegetation on the site itself will tell you when to start a particular agrotechnical measure. You just need to carefully observe her, and everything will become clear.

Description, purpose

inkstone - a versatile and effective remedy for improving the fruit bearing of trees and restoring old trees.

This tool is quite popular among experienced gardeners, but for some reason it is less in demand among beginners and amateurs. In addition, the use of vitriol is available to every gardener, a cheap and proven means.

If you want to get rid of lichens and mosses, there is nothing easier than spraying trees with a solution of vitriol, with a concentration of 5-7%, in early spring. After such a procedure of using vitriol, lichen and moss are destroyed by summer, and the tree looks livelier and healthier. But next year you will have an excellent harvest.
If your garden consists of old trees, then the procedure is recommended to be carried out also in the fall. This will help consolidate the result, prepare the trees for winter and save you from unnecessary worries.

A common mistake is adding lime to ferrous sulfate. That's right, lime can be added to vitriol, but not to iron, but copper. This mistake is often made by inexperienced gardeners, which as a result can have a detrimental effect on the entire garden.

inkstone - is the only fertilizer that can provide a plant with iron in an easily available form, and iron plays an important role in the respiratory system of plants.

Lack of iron is often found in - apple trees, pears, plums, peaches, raspberries, roses, from vegetable crops - potatoes, tomatoes, cabbage. With a lack of iron, chlorosis appears on various crops, which often causes a weak growth of young shoots, underdevelopment of leaves and underdevelopment of fruits.

Positive in the use of ferrous sulfate

• - For the general nutrition of plants, it affects the formation of chlorophyll (gives improved color of leaves and flowers, both flower and fruit crops).
• - Effective against various garden pests, fungal spores, mosses and lichens.
• - Disinfectant and elimination of unpleasant odors from cesspools and summer toilets.

Application of ferrous sulfate:

• Treatment is recommended in early spring or autumn after November. It is used as a microfertilizer by spraying or sprinkling for foliar top dressing.
• Solution rates: The drug is consumed 5-10 g per 10 liters of water. For early spring spraying - before bud break, it is repeated after 15 days.
• House fungus of wood and walls - 1.5kg per 10l of water
• Wood color (from gray to black) - 200-400g per 10l of water
• Whitewashing walls and basement - 600g per 10l of water

Iron vitriol in horticulture:

Disinfection and treatment of wounds and hollows of trees - 500 g per 10 liters of water

Whitewashing trees - 500g per 10l of water

Black spot of roses - 30g per 10l of water

Prevention of chlorosis by spraying leaves - 50g per 10l of water

Argus, currants, raspberries - 250g per 10l of water

Stone fruits - 300 g per 10 liters of water (treatment is carried out against lichens, mosses, gray rot, etc.)

Iron vitriol application in gardening.

Ferrous sulphate, or iron sulfate, is produced by our industry in the form of a crystalline powder of a beautiful blue color. The active substance is about 53% in it. It is popularly known as vitriol. The use of this drug in horticulture is very diverse and deserves detailed consideration.

When ferrous sulfate is required

Gardeners and gardeners traditionally use ferrous sulfate in their farms:

For processing walls of basements and vegetable stores;
- to get rid of the fungus;
- for the healing of hollows and wounds on trees;

For spring and autumn whitewashing of fruit tree trunks;
- for the treatment of horticultural crops against lichens, scab and other similar ailments;
- for the treatment of spotted roses;
- for the preventive treatment of grapes;
- to combat harmful insects;
- as a fertilizer.
Solutions and concentrations

For the treatment of wounds on trees and disinfection of hollows, 100 grams of vitriol is diluted in one liter of water. The same proportions are used when whitewashing trunks.

To eliminate black spot that appears on roses, they are sprayed with a solution of ferrous sulfate at a concentration of 0.3%. But for the prevention of seed crops, he black cancer, septoria and scab, a five percent solution is already used. Treatment against lichens, moss and gray mold requires the use of 30 g of substance per liter of clean water. For the treatment of raspberry or currant bushes, a little less is required - 25 g per liter.

Spraying against pests is carried out twice. During the growing season, you can use only a one percent solution of vitriol, and when the leaves have already fallen off, a five percent solution.

In viticulture, vitriol is used against spotted necrosis, bacterial cancer, anthracnose and other diseases. Vines are treated with a 5% solution, both in spring and late autumn. The next treatment is done with the same composition, but after 14 days. Higher concentrations can severely burn leaves and green shoots.

To destroy the fungus, 1.5 kg of ferrous sulfate are diluted in a bucket of water. The walls of basements and vegetable stores are whitewashed with a solution prepared at the rate of 60 grams of the drug per liter of water.
Destruction of pests

Ferrous sulfate is quite effectively used in horticulture as an insecticide, which allows you to destroy not only the insects and larvae themselves, but even their eggs. For example, with careful processing of trees, from 30 to 50% of the eggs of the apple sucker die - the worst enemy of many fruit trees. Plants are sprayed in the spring, while the buds have not yet blossomed, capturing not only branches and trunks, but also the soil of the trunk circles.

It is very important to correctly determine not only the concentration, but also the timing of the treatment with iron sulfate. In the middle lane, spraying usually begins in mid-April - from 10 to 20. At this time, up to half of all laid eggs die.

If processing is carried out earlier, there is only a risk of wasting time - the insects will not wake up yet and will not have time to lay eggs. And ferrous sulfate cannot destroy hibernating pests. Later use of the drug can harm both the tree itself and the future harvest.

But these terms are not dogma. A thinking gardener does not look at calendar numbers, but carefully observes the spring awakening of plants. If the winter drags on, spraying is postponed to the end of April. But when the buds begin to bloom earlier than usual, and frost is no longer expected, then you can start prevention at the beginning of the month.

Ferrous sulfate is not difficult to use. But it should be borne in mind that he will never give one hundred percent guarantee of the destruction of pests. Therefore, it is not necessary to give up other, more powerful, specialized insect control agents.
Use as fertilizer

But ferrous sulfate is not only a popular insecticidal and fungicidal agent, but also a good fertilizer. The iron included in it is in a soluble form and therefore readily available to plants. Without it, no crops can exist normally - leaves turn yellow, tree shoots die off, flower color deteriorates.

Fruit trees especially suffer with a lack of this trace element: apple, cherry, plum. It is an integral part of oxidative enzymes and plays an important role in the respiratory system. Chlorosis of the leaves, slow growth of new shoots, underdevelopment of fruits - all this, as a rule, is the result of a lack of iron.

As a fertilizer, ferrous sulfate is used in horticulture for foliar feeding of potatoes, tomatoes, and all types of cabbage. In a glass or plastic container, dissolve from 5 to 10 g of the drug and add the volume of liquid to 10 liters. But it should be remembered that in no case should this substance be mixed with lime - it is even better to take soft water for the solution. In contact with calcium, iron forms insoluble compounds, becoming inaccessible to plants.

Ferrous sulfate can be added for digging together with compost: 100 grams of vitriol for every 10 kg of organic matter. Experienced gardeners have long learned how to obtain iron chelate from ferrous sulfate - a highly effective and relatively expensive fertilizer. To do this, first dilute a couple of tablespoons of citric acid in a 10-liter bucket of water. After complete dissolution, iron sulfate is added there - no more than one tablespoon.
Precautions

Unlike copper sulfate, iron sulfate is not such a toxic substance. But when working with him, it is still better to be careful: make sure that the drugs do not get into the eyes, store them separately from the products and use only non-edible dishes for this. If solutions, especially highly concentrated solutions, are spilled onto the skin, they should be rinsed off with plenty of water as soon as possible.

Every self-respecting gardener plans to get the most out of the effort. The easiest way to do this is to use chemicals. It is necessary to feed the plants - chemistry will help. It is necessary to get rid of pests - the same recipe. To make the fruits more attractive - and again chemistry.

Only a few people forget about one very important thing - all the chemicals that modern industry presents in such quantities over time accumulate in the soil. It then ends up in vegetables, fruits, and berries. And then on the table. As a result, a person poisons himself.

It is difficult to grow a rich harvest without additional help, you cannot argue with that. But you can use proven and safer means.

For example, several generations of gardeners have been using such a simple and effective substance as copper and iron vitriol. We will try to get to know the latter better.

What is ferrous sulfate?

Ferrous sulfate, or ferrous sulfate (also known as ferrous sulfate), is the brainchild of the Soviet chemical industry.

It is a crystalline powder of a beautiful greenish-blue color. It contains about 53% of the active substance, which makes it an excellent assistant in garden plots.

What is ferrous sulfate for?

Not to say that this remedy is universal, however, its main function is to fight fungal infections.

Therefore, gardeners use it to solve several problems:

• processing of the ceiling and walls of vegetable stores and basements;
• to eliminate fungus;
• for the treatment of hollows and wounds in trees;
• for off-season (autumn and spring) whitewashing of fruit tree trunks;
• for the treatment of horticultural crops against lichens, scab and other diseases;
• to eliminate spotting of roses;
• for the preventive treatment of grapes;
• to combat harmful insects;
• as a fertilizer;
• for processing grapes;
• for the treatment of real and downy mildew, as well as anthracnose, coccomycosis and gray rot.

One of the most important points is the fact that this vitriol is a substance of contact action, that is, during processing, it does not penetrate into the plant cell and intercellular spaces. Plus, it is quickly washed off with water. This leads to the fact that, unlike other chemical compounds, it does not accumulate in fruits and does not enter the human body.

Iron vitriol against pests

Iron sulfate is an excellent insecticide. Using it in gardening, you can easily cut in half the number of not only crawling insects, but also their eggs. For this, spraying is carried out in the spring. At the same time, they try to touch not only the branches and trunk, but also the ground around the tree.

The most important parameters for spraying are concentration and treatment time. Usually they start spraying in the second half of April. This is considered a good enough moment to eradicate up to half of all pests.

However, it is worth making a reservation here. Calendar and climatic springs do not always coincide. Therefore, an experienced gardener closely monitors the weather, the appearance of buds on the tree, and in early spring he can start processing earlier.

It is not difficult to use iron sulfate. But it must be borne in mind that this is not a super-tool that can once and for all get rid of all problems. Other processing methods can be used with iron to achieve the best effect.

Iron vitriol against mosses and lichens

For getting rid of mosses and lichens, which are most often formed on old trees, iron sulfate is also great.

For a family of shrubs, a 3% concentration of the solution will be sufficient (300 grams of iron sulfide per 10 liters of water). For trees of the stone fruit family, a more powerful solution is required - 5%. Treatment will be carried out in two stages at intervals of two weeks. After a specified period of time, all the moss and lichen will die off and come down from the tree or shrub.

Iron vitriol to fight fungal diseases

In order to prevent fungal diseases from touching garden plants, you will also need to prepare a solution based on iron sulfate. Only this time it will be much weaker than from pests or lichens.

In this case, everything will be enough 30 grams of vitriol per 10 liters of water (a 0.3% solution is obtained). Treatment will need to be done two or three times every seven days.

Iron vitriol against chlorosis

Chlorosis occurs in plants when there is not enough fertilizer or iron in the soil. This disease manifests itself in the fact that the leaves lose their green color, become paler and in some cases become covered with spots. But ferrous sulfate is quite suitable for the treatment of this ailment.

It is enough only to dilute with ten liters of water 50 grams of vitriol, and spray every four to five days until healthy, green foliage is restored.

After the color has returned, vitriol can be used to prevent this disease. For this, the dose of sulphide is reduced to 10 grams per ten liters of water and processed approximately once a week.

Iron vitriol processing of grapes

For grapes, ferrous sulfate is of particular importance. Sulfide is a kind of protector of this culture - treatment with vitriol makes the bud opening of the grapes delay for about a week.

This is good in the sense that, after the covering material is removed and, after a week, the vineyard is treated with vitriol, the buds bloom later than usual, therefore, they are not exposed to the returning cold weather. For this, only a 3-4% solution is enough (how to prepare it is indicated above).

For the full processing of grapes with iron sulfate, the following concentrations are recommended:

• for spring treatment, after removing the covering material - 0.5% -1%;
• to eliminate microorganisms and pests, such as mildew, oidium, grape cushion and others - 4-5%;
• from lichens and mosses - 3%;
• to combat chlorosis - 0.05%;
• for processing in the fall, before winter shelter - 3-5%.

Root dressing

However, ferrous sulfate is used in viticulture not only for spraying. Spring root feeding of grapes with sulfate also takes place. And even, moreover, it bears fruit.

Vitriol is an excellent way of adding iron to the soil. In this way, you can feed not only grapes, but also other fruit crops. However, before you start feeding, you should make sure that the plants really lack iron.

And it can be expressed as follows:

• the growth of young shoots is slowed down, the vine is shorter and thinner than it should be;
• leaves do not grow to the required size, lose color, fall off;
• fruits ripen at a slower rate, that is, the harvest is late and unripe.

There is a possibility that these signs also hint at certain diseases in the plant. But the use of vitriol will obviously not be superfluous, since the treatment of this ailment can also be carried out with sulfite.

Instructions

Like any complex substance, vitriol has its own instructions. It is strongly recommended that you read the Tips and Warnings before using this material.

Most of the useful information is indicated on the packaging, including in what proportions to breed vitriol and for which plants, as well as information on how to protect a person when working with a chemical product.

If there is not enough information indicated on the package, then you can always go to the Internet, where the completeness of the information is provided. Starting from advice on what to wear and what kind of spray guns to use, ending with complex recipes for combining various chemical components.

It is enough just to follow the indicated instructions, on the packaging or on the Internet, and then the best result will not be long in coming.

How to breed?

In order for the solution of ferrous sulfate to be of high quality, you should take care of some points:

1. First, it is a container. The question here is convenience - if the volume of the treated area is very large, then you can use a large container, like a barrel, it is desirable that it has an even volume (it will be more convenient to count) - 50 liters, 100 liters, and so on. The latter option is preferable because it is much easier to do all the calculations.
2. Secondly, the state of the container. It is desirable that it be plastic. Clean and plastic containers. Since vitriol is still a chemical element, it is difficult to guess what reaction can occur if sulfide is poured into a container where a little gasoline remains. Therefore, the container must be clean.
3. Third, the "spoon". The designation is conditional, but you will have to stir the vitriol in the water with something. It can take a very long time if you wait for it to dissolve on its own. It is much easier and faster to stir with something like an oar. Unless, of course, we are talking about a large container.
4. Fourthly, after the first stirring, let the composition brew for twenty minutes. This will allow the undissolved remains of vitriol to settle to the bottom, after which it will need to be thoroughly stirred again. After that, the finished solution can be used for processing. One hundred liters of water will require from three to five kilograms of ferrous sulfate. This will give, respectively, three or five percent composition.

Consumption rates

Possible ratios for preparing solutions were listed above. Nevertheless, there are many versions on the Internet that differ from those listed. This is not bad, as it allows you to experiment and select the necessary dose empirically.

The solution consumption rate is approximately 10-15 liters per 100 square meters... Provided that spraying is carried out through a spray bottle.

Precautions

The standard recommendation when working with chemicals is to wear rubber gloves (disposable), a respirator mask (if you can get a gas mask, it will be ideal), outerwear in the form of the same disposable gown (or permanent, but it should only be used for this).

Spraying the solution goes through a spray bottle, therefore you must have safety glasses. Spraying is carried out only in calm weather, otherwise there will be no sense from processing.

Conclusion

Years of practice show that iron sulfate is an excellent assistant in gardening work. Unfortunately, it cannot be called the most versatile and best, however, it really can be used in many places and there is a lot to fight with.

It is relatively safe, no doubt about it. However, in case of sufficiently severe and neglected cases of plant diseases, it still makes sense to connect stronger chemicals.

To increase the productivity of vegetables and fruit trees, gardeners have to regularly deal with pests and various diseases in both spring and autumn. Many people use industrial chemicals that are harmful to the human body, but there are many safe and proven methods by our grandfathers, because there were no chemicals before. For example, vitriol. Its use is quite effective, and it is not harmful at all. Ease of use gives it another plus. Is excellent. The use in horticulture is based on unique properties in the fight against bacteria, fungi, viruses and other sores of trees and bushes, which are not inferior to the properties of chemicals.

Iron sulfate, as well as ferrous sulfate - all these are different names for ordinary vitriol. It is a salt of sulfuric acid. Appearance - crystals of blue color with a slight greenish tint. It should not be confused with copper sulfate - it has large blue crystals. It dissolves perfectly in water. The areas of application are diverse: chemical industry, metallurgy, energy, fungicide, reducing agent. The melting point reaches 400 degrees.

Chemical formula - Fe2SO4 x nH2O.

Quality standard: GOST 6981-94.

Iron sulfate in agriculture is mainly used for soil reclamation, in the fight against pests and various diseases of trees and bushes, as a fertilizer (it is an excellent catalyst for the formation of chlorophyll). In addition, it is used in the manufacture of building materials, in the manufacture of batteries and many other industries.

Ferrous sulfate, although not flammable, is explosive. When working with it, you must observe safety precautions.

Due to its excellent restorative properties, it makes it possible to make gold refining. This is the process of obtaining high-grade gold and other non-ferrous metals. Simply put, it helps to cleanse them of various impurities. This refining method can be done independently at home.

What is it used for in gardening?

Vitriol in horticulture is the most versatile fertilizer that can effectively restore old trees and increase yields, fight various harmful insects and diseases of plants and trees. Perhaps there is not a single nasty thing with which he could not cope. It is considered a popular remedy among gardeners with extensive experience, but not used by beginners and amateurs, they prefer industrial chemicals. However, ferrous sulfate still remains the most affordable and proven remedy. This is one of the fertilizers that can provide any plant with iron in the most accessible form. In particular, iron is needed by the root system to improve respiratory function. Especially old trees need such feeding.

It is necessary to carefully feed the soil with vitriol. Dig in its crystals along with the compost during the fall digging. During the winter, the soil will be saturated with iron and be able to give it to plants. It is often lacking in bushes, and roses are highly dependent on the amount of iron in the soil. They require careful care and more than other plants need this element. Iron sulfate is an excellent helper in the garden and vegetable garden. It can be easily used at home.

Vitriol crystals contain about 50% of iron trace elements. Currants and gooseberries simply cannot develop properly without this fertilizer. It has excellent fungicidal properties and is an assistant in the fight against plant diseases, and the treatment of grapes with this solution will save it from many diseases.

Vitriol made of iron, in contrast to copper, has a wider spectrum of action and is less toxic to humans. This element fights against harmful insects, eliminates fungal diseases, scab, lichens and other diseases. It can heal tree cuts and wounds and is widely used as a fertilizer. It is sold in the form of a crystalline powder with an unlimited shelf life without losing its beneficial properties. Store it in a dry place.

Application methods

With the correct use of vitriol from iron at home, fruiting increases significantly, pest control becomes more effective. Despite its availability and low cost, it is an indispensable tool for gardeners. After its application, the scab damage decreases, fruit rot, leaf spot and raspberry bushes, anthracnose of currant bushes disappear, rust completely disappears. With regular use, the affected tree bark becomes smooth and the pale leaves are saturated with a natural green color. Processing should be done both in spring and autumn.

Instructions

1. During autumn and spring digging, add the mixture along with the compost to the soil. 1 kg of this fertilizer per 100 kg of compost. This will help enrich the soil with iron, which is necessary for the respiration of the plant root system. All fruit and berry trees need it.
2. To disinfect wounds on trees and bushes, a special solution is needed. Dilute iron crystals (100 grams) in 1 liter of water. Treat all damage with this mixture. This solution is also suitable for whitewashing trees in the autumn. It is advisable to do this from mid-October to mid-November. This type of autumn processing will prevent the development of fungal diseases.
3. For scab and black cancer, use a 7–8% solution. Take an eight liter bucket of water and dissolve 600 grams of vitriol in it. Trees are thoroughly sprayed with this solution. This procedure is carried out in the fall after harvest. In early spring, until the buds have blossomed, make 1 treatment with 1% solution.
4. For conventional treatment of shrubs, it is necessary to dilute 250 grams of vitriol in 10 liters of water and spray the plants. To combat apple sucker, a 3% solution is needed.
5. Small patches of moss are the harbingers of lichen. Such sores are treated with a mixture of 5% vitriol and ash extract. It is necessary to coat the trunks with this in the fall, when all the leaves fall off. This method is considered the best for lichens and moss.

Also, cellars and basements can be treated with vitriol solutions. Treating the walls with a weak solution will get rid of unpleasant odors and mold.

Not to be confused with copper sulfate! It is strictly forbidden to mix iron crystals with slaked lime. Treatment with such a solution can lead to disease and further death of fruit and berry plants and grapes.

Application in viticulture

Autumn processing should be carried out regularly. This is easy to do. Vitriol will help with this honey agaric. It disinfects branches, kills fungus and mold, destroys other harmful insects. This procedure is carried out in late autumn after complete leaf fall. 500 grams of iron powder is stirred until it is completely dissolved in water. Next, each grape trunk is carefully sprayed.

Wear protective gloves and a mask while spraying to help protect your skin from unwanted spraying. Although vitriol is not very harmful to humans, skin and respiratory protection is still necessary. This treatment is especially important if the garden is not young. Old trees and shrubs require more careful care, because over a long period of time, a huge number of diseases could accumulate, the soil was depleted. The treatment will help get rid of lichens, cytosporosis, moss, black crayfish and tree scab.

To improve the quality of whitewashing, add a little sulfate to the solution - this will be an excellent remedy for fungal diseases of grapes. Spring treatment with a weak solution will be a good prevention of iron deficiency. With regular and proper processing, all your grape bushes will acquire a beautiful and smooth bark, it will become more elastic. As early as next spring, the leaves will acquire a healthy color and become much larger in size. Accordingly, more shoots will grow, the yield will increase. The bunches will become larger and the berries will look beautiful.

Precautions

Iron powder is diluted only with water. For this, you can only use containers made of plastic or glass. Under no circumstances should metal utensils be used. When working with powder and mortar, safety precautions should be followed. Be sure to wear a respirator and rubber gloves. If the substance comes into contact with the skin, rinse it with plenty of water. Although the powder is safe for humans, do not neglect protective equipment.

The use in horticulture and viticulture of copper and iron vitriol remains relevant. Having established themselves as reliable means of fungicidal action, they are used in autumn for the disinfecting treatment of garden trees and soil. Learn how to use iron and copper sulfate, and what harm these substances pose to humans, from the article.

How to use iron sulfate in the garden

Iron sulfate is a fine crystalline ferrous sulfate powder used in horticulture:

• as an iron-containing fertilizer that promotes the restoration of old trees and an increase in their fruiting;
• as a disinfectant in the treatment of wood wounds and hollows, as well as premises for storing vegetables;
• as an insecticide to protect against insects, their larvae and eggs;
• as a fungicide to protect against fungi, rot, lichens, mosses.

Attention! Iron deficiency is the reason for a decrease in the activity of photosynthesis, yellowing of foliage and the development of chlorosis in fruit trees.

inkstone

• coccomycosis;
• scab;
• alternaria;
• clasterosporium disease;
• gray rot and other fungal diseases.

Usually, iron sulfate is used to treat trees in the fall, since spring treatment with this preparation can cause burns in young leaves.

• for disinfection of stone fruit trees, it is recommended to use a 3% solution;
• for pome trees - 4%;
• for shrubs - 1-2%.

Attention! An important condition for the effectiveness of ferrous sulfate is strict adherence to the dosage and concentration of solutions.

To enrich the composition of compost introduced in autumn or spring with iron, add 10 g of vitriol for every kilogram of organic matter.

How to use copper sulfate in an autumn garden

Copper sulfate is known as a highly effective contact fungicidal agent that can cope with diseases such as:

• moniliosis;
• cytosporosis;
• scab;
• anthracnose;
• black cancer;
• septosporosis;
• various types of spots and rot.

Copper sulfate

Copper sulfate acts locally, without penetrating into the tissues of the treated plants, washed off by rain and water during irrigation. It is used for both preventive and therapeutic purposes in late autumn, as well as for pickling before planting berry seedlings - raspberries, currants, gooseberries and strawberry seedlings. To prepare the etching solution, dilute 100 g of copper sulfate in 10 liters of water, and then completely dip the seedlings or seedlings into the resulting solution for 3 minutes. After that, the plants should be rinsed and planted.

Advice! Since the solution of copper sulfate cannot be stored for a long time, it is recommended to prepare it immediately before use.

Copper sulfate acquired the greatest distribution in the form of Bordeaux liquid, which can be prepared independently by taking 10 g of slaked lime and copper sulfate per 1 liter of water.

The use of vitriol in viticulture

Iron vitriol in viticulture is traditionally used as the prevention of specific fungal diseases

• necrosis, characterized by the withering away of individual parts of the grapes;
• oidium, the symptoms of which are white powdery bloom on the bunches, leading to a decrease in the quality and quantity of the crop;
• anthracnose, the first symptoms of which are the appearance of brown spots on the foliage, over time leading to a loss of 70% of the deciduous mass and a twofold or even threefold reduction in yield.

Advice! To avoid contamination of vineyards with such diseases, every year in the fall, after the foliage has fallen, it should be sprayed with a 5% solution of ferrous sulfate.

Iron vitriol will rid trees and shrubs of mold and moss

In parallel with fungicidal preventive treatments, vineyards in the spring should be fed with complex fertilizers that help strengthen the immunity of plants, increasing their resistance to infection with fungal and other diseases. Top dressing with iron-containing fertilizers is of great importance here, since due to a deficiency of iron in the soil, vineyards become vulnerable to chlorosis, which can be cured by spraying with the same solution of ferrous sulfate.

In case of detection of the first signs of necrosis or anthracnose on grape bushes, the treatment of the affected stems and leaves with a 3% solution of Bordeaux liquid will allow to suspend the development of the disease, repeated spraying, but already with a 1% solution, should be carried out after 7 days for preventive purposes.

Grapes with copper sulfate are processed in autumn

Why is copper and iron sulfate dangerous?

Despite the fact that 1% and 3% solutions of copper sulfate are among the oldest and most used plant protection products, their use can pose a threat to humans. Contact with such a solution on the skin causes allergies in the form of rashes and itching, and accidental ingestion can cause serious poisoning.

Attention! The use of copper sulfate requires special care, since it is a toxin that can harm human health.

In this regard, solutions of copper sulfate are not recommended to be used as fertilizers or for preventive soil cultivation, thereby excluding the possibility of a dangerous excess of copper concentration in the soil. The exception is peat soils, which are usually copper depleted. To enrich them, once every 5-6 years, it is permissible to introduce copper sulfate at the rate of 1 g per 1 m².

Vitriol can cause allergies and itching, therefore it is necessary to work in a protective suit

Avoiding the need to use copper sulfate as a disinfectant in soil processing will allow compliance with the elementary conditions of crop rotation. To protect plants from late blight, instead of copper sulfate, it is better to use safer means, for example, a biological product - "Photosporin", and for preventive treatment of roses - "Kuproksat" or "Hom".

In view of the possible danger of using copper sulfate, it is recommended to spray tree crowns exclusively on a green cone - that is, at a time when the tree buds are just beginning to gain color. And it is better to abandon its use in favor of a safer remedy - Bordeaux liquid.

Iron vitriol, although not as dangerous to human health as copper sulfate, is nevertheless a prerequisite for working with this substance.

When breeding vitriol, it is important to observe the proportions

If you need to work with copper or iron sulfate, you should:

• wear gloves and a mask or respirator, cover your hair with a headdress;
• change into overalls and closed shoes;
• at the end of work, wash your hands with gloves and change clothes, wash.

Despite the abundance of modern fungicidal agents, vitriol - iron and copper remain in demand due to their high efficiency. In order for these funds to bring only benefit, dosages and safety conditions should be strictly observed.

Caring for a garden and a vegetable garden includes not only the timely planting of cultivated plants, their watering and loosening the soil, but also feeding with the help of various mixtures and solutions. One of the most popular fertilizers is ferrous sulfate crystals, which have been successfully used for several decades. This is a drug that not only helps to fight pests, but also saturates the soil with a useful trace element - iron.

Iron vitriol - 5 useful properties

Ferrous sulfate, ferrous sulfate, ferrous sulfate - all this is the name of the same substance. It is a chemical that is pretty turquoise crystals and is very often used in horticulture, especially by older gardeners. Young people are skeptical about crystalline hydrate mainly because of the low price. But completely in vain, because the use of such salt helps to solve many problems, namely:

1. 1.increase in soil acidity and its saturation with iron;
2. 2. protection against harmful insects;
3. 3. getting rid of fungal diseases and infections;
4. 4. fight against the formation of lichens and mosses on the tree trunk;
5. 5. treatment of damage to the trunk or branches of the tree.

For the treatment of trees and shrubs, iron sulfate is used in the form of an aqueous solution, and the protective effect lasts two to three weeks. Fungicide should not be mixed with phosphate fertilizers, lime and copper sulfate. The chemical reaction from the combination of drugs will not harm the plants, but will simply render the agent unusable.

Before using ferrous sulfate, you should carefully study the instructions for use, observe safety precautions, because the drug has high acidity and can cause burns to the epidermis. That is why they are not recommended to handle young shoots of plants and shrubs. Surprisingly, ferrous sulfate can be used not only in gardening, but also effectively fight against the formation of fungi on the walls of houses, sheds and other buildings.

Methods of using the drug

Experienced gardeners advise to process trees and shrubs twice a year - in spring and autumn, that is, when young leaves have not yet appeared on the branches or when they have already fallen off. The concentration of the solution is also different. It varies from what tasks the owner of the infield sets himself.

Ferrous sulfate treatment is useful even for healthy trees: it does not penetrate inside, but, at the same time, it is safe and has a positive effect on the growth of branches, the supply of fruit buds and yield. In this case, a too concentrated solution is not used, that is, the crystals are diluted in a large amount of water.

If the treatment is carried out not only for preventive purposes, but also for the fight against diseases and pests, then the concentration of the mixture is higher. Most often, ferrous sulfate is used for fruit trees, strawberries and flowering shrubs. The work takes place as follows:

• a solution of the required concentration is prepared;
• the mixture is poured into a special spray device or a simple spray bottle;
• the mixture is carefully sprayed over damaged branches or leaves of plants.

It is important to remember that for effective treatment, the garden should only be sprayed in dry and calm weather. It is possible to add crystals of the substance to whitewash for trees and shrubs.

Iron sulfate is popular due to the fact that it successfully combats many pests and diseases, for example: scab, fruit and gray rot, powdery mildew, mosses and lichens, and premature foliage. After careful processing, the insects die, the lichen separates from the bark and no longer grows, and the yellow leaves, suffering from a lack of a trace element, become more alive and acquire a bright color.

The solution is actively used in viticulture for processing vines. The popularity of ferrous sulfate for spraying grapes is due to the fact that this substance can inhibit the development of the kidneys, which means it will help to survive frost and increase resistance to cold. To achieve this goal, the plant is sprayed in early spring - 7 days after removing the shelter, when the buds have not yet opened.

How to prepare the solution yourself?

Ferrous sulfate crystals contain 53% of the active substance, but for work they must be diluted in a certain concentration. Most often, a 3% solution is used, which will not be difficult to prepare. You just need to dilute 300 grams of powder in 10 liters of water. It is necessary to carry out processing on the same day, because the product quickly loses its effectiveness. A preparation of such saturation is sprayed on such fruit trees as cherries, plums, peaches, apricots.

For apple, pear and grapes, a stronger solution is useful - 400-500 grams per 10 liters. The most saturated mixture is made to combat mold, moss and lichen - 500-600 grams for the same amount of water. To saturate the soil with iron or protect the grape buds from frost, a very weak solution is prepared - only 50 grams per 10 liters. The required amount of powder is calculated depending on the area to be treated.

Despite the proven effectiveness of ferrous sulfate, not all gardeners use it. Some argue that the treatment with iron sulfate has very dubious benefits, since spraying the surface does not completely kill the fungus and pests. In addition, if you do not study the instructions enough, you can harm young shoots or completely lose valuable crops. Therefore, inexperienced gardeners are advised to use copper preparations.

Although ferrous sulfate is an almost non-toxic substance, it is necessary to adhere to some rules in working with it, namely:

• dilute the mixture in plastic or glass containers that are not subsequently used for cooking and eating food;
• use disposable gloves and a mask to prevent the powder from entering the respiratory tract;
• use the drug only as directed and keep out of the reach;
• in case of contact with skin or eyes, rinse immediately with plenty of water.

Although reviews of sulfate iron are very diverse, it is still considered the most versatile tool for processing fruit trees and shrubs. Regular use of this substance will help you get rid of pests, fungus, lichen and other diseases in your garden.

Ferrous sulfate is a universal fertilizer that contains up to 47-53% of iron trace elements in a form available to plants.

Crystalline powder of a beautiful greenish hue, known to most of us as iron sulfate, has been used in horticulture for many years. No less popular is its "brother" copper sulfate, which has a characteristic bluish tint. What properties the powder has, and what effect it can have on plants, we will consider in this article.

Copper and iron sulfate: what is the difference

Iron and copper sulfate have a different composition of microelements and therefore can have different effects on the vegetative process of plants.

Without ferrous sulfate, many berries simply cannot exist, for example: currants and gooseberries. Iron vitriol is also a fungicidal agent that can be used to successfully combat fungal diseases of plants, as well as mold and rot.

Copper sulfate or copper sulfate are blue crystals that contain up to 24% copper.

Copper sulfate is used in the garden to feed plants on sandy and peaty soil types, which are poor in mobile forms of copper. Plums, pears, and apple trees are more sensitive to a lack of copper. It also has disinfectant properties. It is indispensable in the fight against plant diseases such as moniliosis and bacteriosis, late blight and scab.

If we compare these two means, then ferrous sulfate is capable of providing a wider spectrum of action. Moreover, it is less toxic.

Owners of suburban areas with the help of iron sulfate solve several problems at once:

• fight against harmful insects;
• getting rid of spores of the house fungus;
• treatment of horticultural crops from scab, lichens and other diseases;
• treatment of cuts and wounds in trees;
• vitriol is used as a disinfectant to eliminate unpleasant odors from cesspools;
• as a fertilizer.

Iron sulfate is a necessary element, in case of insufficient intake of which, premature yellowing of the foliage occurs.

The use of ferrous sulfate in horticulture leads to an improvement in the condition of the bark on trees. After treatment with the solution, the bark on the tree becomes soft and elastic. And thanks to its ability to influence the formation of chlorophyll, foliage after processing acquires a rich dark shade.

Solutions and concentrations of the drug

Iron vitriol is produced in the form of a crystalline powder, which has an unlimited period of action. Store it in a clean and dry place. To prepare the drug, the powder is diluted in water, the concentration depends on its purpose. But most often they use a solution with a strength of 5-8%.

Important! Regardless of the concentration of the finished composition, the crystalline powder should be diluted with water only in a plastic or glass container, but not in a metal container. When working with powder, it is important to follow safety rules and in case of contact with open skin or eyes, rinse with water.

For the treatment of cuts of wounds in trees and disinfection of hollows, 100 g of powder is diluted in one liter of water.

This proportion can also be used in the manufacture of a composition for whitewashing trunks.

To get rid of gray mold, lichens and moss, a less concentrated solution is required, made from 30 g of powder per liter of water. A solution of this concentration can also be used in the treatment of currant or raspberry bushes. It is also effective in the fight against black spot of roses.

Options for the use of iron sulfate in gardening

Destruction of pests

Work is carried out until the bud breaks. The optimal period is considered to be in the first half of April, since at this time up to half of all laid eggs can die. Earlier processing will not give the desired effect - insects simply do not have time to lay eggs, and later application of the drug can harm the future harvest.

Disease prevention

It is possible to eliminate lichens and mosses that appear on the trunks of fruit trees by treating them with a composition based on a 5% solution of ferrous sulfate with the addition of ash extract. The treatment of the affected areas is carried out by spraying or coating in the period after the foliage has fallen.

Experienced gardeners use iron vitriol in viticulture. By processing grapes by spraying, they successfully fight diseases such as spotted necrosis, mildew, cushion cushion, anthracnose, oidium, and bacterial cancer. To do this, they use a 5% composition, which is sprayed onto vines with not yet blossoming buds. Re-processing is carried out in 10-15 days.

As a fertilizer

Iron sulfate is widely used in horticulture as a microfertilizer. After all, it acts as an integral part of oxidative enzymes, while playing an important role in the respiratory system. The consequence of iron deficiency is slow growth and death of young shoots, yellowing of foliage, deterioration of flower color, underdevelopment of fruits.

Vegetable and fruit crops are fed by spraying or sprinkling.

Important: the finished composition cannot be applied to green foliage, otherwise it will leave burns on it. Spraying is carried out before bud break in early spring or when the trees lose their deciduous mass.

Early spring spraying is carried out in two stages, maintaining an interval of two weeks, irrigating tree branches with a 1-3% solution. After the leaves fall, a more concentrated 5% composition can be used.

In addition to treating crops in the spring and autumn, fertilizer can be used together with composting in a ratio of 1: 100. The finished mixture is brought in when digging near-trunk circles in the fall or spring.

It is not difficult to use ferrous sulfate, but it does not give a 100% guarantee of achieving results. Therefore, it is desirable to combine it with other means of combating diseases and pests.
