Copper sulfate is widely used in everyday life and industry. Without his participation do not pass chemical reactionsand in recent times it has become fashionable to engage in cognitive chemistry, within which beautiful crystals are grown from copper sulfate. Agricultural technology is not complete without its use.

Why is this substance so popular and how to use it correctly at home? This will have to be dealt with, because ignorance of the proportions for concentrates and solutions can lead to irreversible consequences, for example, the complete death of the crop during the season.

How to do in agricultural technology without the use of such a solution as copper sulfate? Thanks to its successful use, it is possible to carry out prevention and prevent a number of diseases from which garden and garden crops... Therefore, novice gardeners are interested in how to dilute copper sulfate. Did you ask? Explore!

Basic connection information

Copper sulfate is known in narrow circles as bivalent copper sulfate pentahydrate. Outwardly, it looks like a blue (blue) crystallized powder with hygroscopic properties. See the photo below for how the product on the market looks like.

The substance is actively used in agriculture. It is packed in 50-100 gram sachets or bottles. Poisonous, belongs to the 3rd class of danger. It strongly poisons the body when ingested or on mucous membranes. With careless handling, only 30-45 milliliters of solution (5%) may be enough for a lethal outcome. It is important to know how to dilute copper sulfate so that its concentration is safe not only for the person in contact, but also for the crops that are supposed to be processed.

Interesting! The peculiarity of the substance is that it can get inside human body and through skin, with the reverse absorption of sweat. Therefore, it is recommended to work only in closed clothing, supplementing the suit with a protective mask, gloves made of rubber and special glasses.

Working with copper sulfateDo not forget about protective clothing and safety precautions. You may be used to hearing this name and working with this unsafe product, but careless handling can lead to unwanted consequences.

Use of commercial copper sulfate in gardening

Copper sulphate has been used by humans since ancient times. Today it is widely used in horticulture. Often on the forums, summer residents ask how to dissolve copper sulfate. Its use is due to objective reasons:

1. By observing the recommendations for the use of the substance, you can not worry about the toxicity of the solution. With the correct consistency, it does not have a cumulative effect, does not have a detrimental effect on plants, and its use is not accompanied by long-term side effects.
2. The composition is characterized by biocidal and fungicidal action.
3. It is an effective remedy against mold and its various forms.
4. Copper sulfate does not provoke resistance, does not cause addiction and resistance to harmful forms: bacteria, fungi, pests, mold.
5. It copes well with the task of fertilizing the soil, since it contains copper ions Cu (II), which are so necessary for living plant forms to produce a number of essential phytohormones.
6. It is inexpensive when compared to synthetic supplements for a similar purpose.

Solutions and their concentration

So, in what proportions and how to dilute copper sulfate in order to process the plants efficiently and not harm garden crops.

Depending on the seasonality and purposes, the treatment is carried out using various kinds of solutions and liquids. In any of the existing cases of agricultural crops, 1 of 3 degrees of concentration of copper sulfate is used:

1. "Burning out" solution 3-5%. Proportion: 30-50 grams of copper sulfate is dissolved in 10 liters of water. Rarely used for treatment when absolutely necessary to decontaminate an area or take measures to combat mold in building structure... After processing by means of "burning out", such soil is taken out of service for at least a year, until the concentration of the solution in the soil disappears.
2. Therapeutic and prophylactic essence is a 0.5-1% solution obtained by mixing 5-10 grams of powder with 10 liters of water. It is used to combat fungal infections and to prevent anthracnose, clotterosporia, coccomycosis, etc. Suitable for spraying and processing garden trees for the purpose of disinfecting wounds on trunks and branches.
3. 3 in 1: top dressing + fertilization + prevention. For such purposes, a medium concentrated solution is used - 0.2-0.3% (2-3 grams of copper sulfate per 10 liters of water) solution. It is used if copper starvation is observed in plants, recognized by such signs: chlorosis of the leaves, twisting of the ends of the shoots, increased tillering without the formation of productive shoots, as well as for the purpose of prevention.

When using a weakly concentrated and a solution of medium concentration for peaceful purposes, you can prepare a stock solution (10%) with a margin. Keep such liquid tightly closed. plastic containerby placing in a cool dark place. Water is added to the concentrate as needed. You already know how to dilute copper sulfate for cultivating land, plants and agricultural buildings. Check out the object handling technology if necessary.

Features of the use of copper sulfate

In the spring, it is customary to carry out treatment for therapeutic and prophylactic purposes. For this, the following solutions of copper sulfate are used:

• 0.5% for watering the soil at the rate of 3.5-4 liters per 1m 2, provided that the average daily temperature exceeds +5 o C. Used against fusarium root crops, white and gray rot of tomatoes, black leg of cabbage. By the way, this is the generally accepted way of diluting copper sulfate for a tomato.
• Before the buds bloom, they are treated against the diseases listed above by spraying with a 1% solution.
• In order to disinfect the root system of seedlings, they are dipped for 2-3 minutes in a 1% solution of copper sulfate, after which they are rinsed abundantly with water.
• Late blight can be prevented by spraying potato tubers immediately before planting with a 0.2% solution of copper sulfate.
• You can achieve early shoots by soaking the seeds in a warm solution (0.2%): cucumbers - 8-10 hours, others - 20-24 hours.
• If you suspect hereditary (if the option of acquiring a healthy planting material disappears) disease, seeds of tomatoes and pumpkin are pickled. Component composition: copper sulfate - 1 g, boric acid - 2 g, potassium permanganate - 10 g, water - 10 liters. During processing, the seeds are soaked and left for 15 minutes in a liquid at room temperature. After that, take out, remembering to rinse under water.

In the summer, copper sulfate is used against mold. How to dilute powder for different types processing, read on.

Garden crop processing in summer

In hot weather, it is preferable to carry out the following procedures:

1. Spraying: fruit trees and shrubs are treated with a solution with a 0.5-1% concentration of copper sulfate, if there are clear signs of the disease (picture below).
2. Watering: tomatoes and potatoes are fertilized unscheduled in order to prevent copper starvation and late blight, using a 0.2% solution at the rate of watering 2-3 liters per 1m 2. Re-processing is carried out after 14-28 days, if necessary.
3. Treatment of wounds of fruit trees - 1% solution, shrubs - 0.5%.

Recommendations for the treatment of garden and other cultivated plants for medicinal purposes

It is important to know not only how to breed copper sulphate for spraying, but also that the use of such a processing method is unacceptable during the flowering period.

Autumn processing is predominantly preventive. It is carried out after the leaves are dropped. Copper sulfate is generally indispensable for such purposes.

How to properly dissolve copper sulfate in water?

Let's start with the fact that it is strictly forbidden to manipulate copper sulfate in living quarters... This substance interacts well with water and dissolves easily. However, with room temperature due to impurities in the composition of sulfites ready solution turns out cloudy, and the precipitate falls out only after 30-60 days.

Copper sulfate dissolution technology

Copper crystals are dissolved in boiling water (from 50 about C). Experts say that it is undesirable to use a special chemical kitconsisting of thin-walled dishes.

The solution has a strong electrolytic property, therefore, if the vessel is damaged, a serious accident can occur.

It is better to dissolve vitriol in a water bath, and store the finished cooled liquid in PET or glass containers for up to 12-18 months from the date of manufacture, placing the container in a dark place.

Now you know how to breed copper sulfate for trees and other crops.

How to prepare Bordeaux liquid?

The acidity index of copper sulfate is considered to be a significant disadvantage of the solution. Its concentration can be reduced by adding 200-500 milliliters of boiling water to the working concentrated solution, having previously dissolved 3-5 grams of water in this volume laundry soap... Such an additive will provide better adhesion of the solution to the leaf plates and will help the solution stay on the surface of the plant longer.

If you know how to dilute copper sulfate for processing tomatoes and other horticultural crops, then the preparation of Bordeaux liquid, more effective meanswill not seem difficult to you.

Bordeaux liquid is a combined solution of copper sulphate and slaked lime. It is prepared in two proportions:

• strong (3%): copper sulfate - 300 g, lime - 400 g, water - 10 l;
• sparing (1%): copper sulfate - 100 g, lime - 100 g, water - 10 l.

The concentrated solution is used for autumn prophylaxis, sometimes for early spring treatments of shoots, sparing - during the growing season of trees.

The only difference between Bordeaux liquid, which can hardly be counted among the advantages, is incompatibility with any other ingredients, in particular, with soap and common drugs. And its soda ash substitute, Burgundy liquid, is not famous for its effectiveness.

Additionally

If you need to prepare a modified or weakly concentrated solution, you will have to dilute copper sulfate. The use of both concentrated solutions and gentle liquids requires caution not only with respect to the treated crops, but also personal safety.

What is needed to carry out the reaction?

To prepare Bordeaux liquid, the required volume of water is divided in equal proportions into 2 vessels, in which the components of the liquid are dissolved separately. The blue solution of copper sulfate, stirring gently, is poured into a white concentrate of milk of lime. Ready mix leave to brew for 3-4 hours. After the expiration of time, filter and pour into the sprayer. A freshly prepared solution is used within a day, otherwise it will lose its properties.

Now you know how to breed copper sulfate.

The use in horticulture as a fertilizer, a means for combating pests and diseases of copper sulfate has already become the norm and even despite its insecurity, the use of copper sulfate remains predominant when choosing a means for reliable protection garden and horticultural crops growing in the summer cottage. Choose only best remedy for plant protection and remember that caution never hurts.

Early in spring in the gardens, preventive processing of fruit trees and shrubs from diseases and pests. Best time for spraying:

• end of March - April, before bud break, on bare branches.

Traditionally, trees are treated with solutions containing copper sulfate, ferrous sulfate, and a concentrated urea solution. As an alternative, many new, modern drugs have also appeared. Apply the good old copper sulfate - cheap and effective. Let's dwell on it 😉

Application of 0.5% - 1% solution

For processing trees in early spring apply a solution of copper sulfate in a dosage:

• 50 - 100 g per 10 liters of water.

Thus, a 0.5-1% solution is obtained. They are sprayed on trees and shrubs in the spring, on dormant buds. 1% m solution can also disinfect wounds on the bark, and with a 0.5% m solution, soil is shed in early spring to prevent all kinds of rot (4 liters per 1 m2 is enough).

In early spring, a solution of copper sulfate can be sprayed:

• pome crops: apple, pear, quince,
• stone fruit: apricot, peach, plum, sweet cherry, cherry,
• berry bushes: gooseberries and currants.

Table: Dosage of copper sulfate for treating trees in spring

A solution of copper sulfate is also used in summer, but in smaller dosages (2-5 g per 10 liters of water) for foliar dressing at the first signs of copper deficiency:

How to breed copper sulfate for processing trees?

So, the proportions are known. For early spring treatment, we need a 1% solution (100 g of copper sulfate per 10 liters of water). It should be noted that crystals of copper sulfate are poorly soluble in cold water... That is why it is recommended to breed copper sulfate in the following sequence:

1. Pour the preparation into a bucket (preferably plastic or enamel to avoid oxidation).
2. Pour the powder with 500 ml of hot water (50 degrees).
3. Stir so that the powder dissolves better, leave to stand for a while.
4. Add the remaining 9 liters with a "tail" to the bucket, mix again.

Since the drug is chemical, safety measures must be observed when working with it: wear gloves, it is best to prepare the solution outdoors, avoid contact with eyes, do not take inside.

By the way

If you don't have scales at hand, the following information will be useful:

• A matchbox contains 22 - 25 g of copper sulfate,
• In a tablespoon: 16 g of copper sulfate,
• In a teaspoon: 5 g of copper sulfate.

Spraying with copper-containing solutions

Currently, copper sulfate is rarely used alone. Solutions in combination with other components are considered much more effective:

• Bordeaux liquid \u003d copper sulphate + slaked fluff lime... In the spring, before bud break, a 3% solution is used: 300 g of copper sulfate and 225 g of hydrated lime-fluff per 10 liters of water. It turns out a ratio of 1: 0.75, although very often they take 1: 1 (300 g of copper sulfate and 300 g of slaked lime-fluff per 10 liters of water). In summer, a 1% solution is used: 100 g of copper sulfate and 75-100 g of slaked lime fluff per 10 liters of water. Bordeaux liquid acts softer than pure copper solution: lime neutralizes, softens vitriol. In the preparation of Bordeaux liquid, there are several important nuanceswhich are better to read about.
• Urea + copper sulfate... Dosage: 700 g of urea per 10 liters of water + 50 g of copper sulfate. Processing is carried out before bud break by spraying.
• Copper-containing fungicide preparations: Hom, Oksikhom, Abiga-peak, according to the instructions on the package.

Iron vitriol for processing trees

In addition to copper, iron sulfate is also used. The goal is the same - to destroy pathogens of fungal diseases, mosses and lichens in early spring. Spraying of trees and shrubs is also carried out BEFORE the buds swell. But the frequency of treatments and dosages are different. Here we will give information from two sources, since the proportions for preparing the solution are different in them:

1. Before the buds swell (about mid-April), trees are sprayed with a 3% solution of ferrous sulfate: 300 g per 10-liter bucket of water.
2. Before swelling of the kidneys, once every 4 years, it is possible to treat with a 5% solution of ferrous sulfate: 500 g per 10-liter bucket of water.

As they say, in war all means are good, the main thing is not to miss the deadline. Remember: end of March - April, before the kidneys swell, it is time to carry out the treatment with solutions containing copper sulfate. It is effective and safe. It is much better to deal with pests, even if chemical means before fruit formation, than then to sprinkle everyone in a row over fruits and berries, destroying pests that are already noticeable with the naked eye.

Warm weather and rich harvests at your summer cottage! 😉

Foreword

Finally, spring has come and gardeners rushed to their suburban areas... Now they have a lot of work to do, including spraying the garden early in the spring. But before that, there is one more thing to do.

Early work in the garden

Now is the time to shake off the snow from the trees. It is wet, heavy and may well break branches. Nature wakes up after winter. Therefore, in early spring, it is necessary to carry out a certain set of measures on the site.

Carefully inspect the branches of fruit trees for pests that have overwintered on them. Now is the time to think about pruning broken and dry branches, so bring them with you. You can also shape the crown of trees.

But the main job is still to spray the trees. As soon as average temperature air reaches + 5 ° C, and the buds have not yet had time to bloom, you need to fight diseases and feed the trees.

Preserving trees from spring burns and controlling pests

In early spring, the weather is rather unstable. It can be high during the daytime and drop sharply at night. Under these conditions, the bark of trees is heated unevenly. Suppose, on a warm March day, the temperature of the trunk in the sun will be 12 degrees higher than on the shaded side. Lime whitewashing of the trunk helps to get rid of such a difference.

In this case, the readings will differ only within 3 or 5 degrees. Overheating of the bark followed by freezing can cause early spring burns. And they will lead to the death of the tree, especially if it is a young seedling. It is necessary to restore the whitewash if it was disturbed during the winter period.

When pruning garden trees in early spring, you need to get rid of damaged branches. They should not be left under a tree, because they are probably infected with: cytosporosis, scale insects, bark beetle larvae, black cancer or other pests and diseases.

Simultaneously with this work, it is required to treat the existing wounds on the trunks and branches. Damage is cleaned, leveled with a knife until living tissue appears, then disinfected with a 1% solution of copper sulfate, in a proportion of 10 g per 1 liter of water, and thoroughly cover this area with garden var.
How to spray trees in early spring

The modern industry offers many various means for spraying trees at the very beginning of spring. For these purposes, the following applies:

• copper sulfate;
• mineral oil emulsion;
• bordeaux liquid;
• emulsion "Preparation-30";
• nitrofen and others.

The cheapest drug is copper sulfate. But don't look at him low cost, it is quite effective, so most gardeners prefer it. It is used for scab, fruit rot, curly leaves, black cancer, brown leaf spot and other diseases.

Mineral oil emulsions are liquid mixtures of mineral oil with water and an emulsifier. The emulsifier usually contains:

• soap;
• glue or kaolin;
• iron or copper sulfate.

Emulsions fight against such pests as: aphids, scale insects, help to destroy the eggs of the moth, copperhead and other insects. They should be applied in early spring, before the buds open. In summer, at temperatures over 35 ℃, the emulsion can cause severe burns on wood.

Bordeaux liquid is an opaque solution of heavenly blue... Gardeners have been using this liquid for more than a hundred years in the fight against garden pests. It is recommended to use it before bud break. The mixture destroys scab and fungal diseases of trees or shrubs. It is also used as a disinfectant for fruit tree wounds. It is not recommended to store it, it must be used immediately after preparation.

Emulsion "Preparation-30" is an oil-oil emulsion of white or light gray color. It is packaged in 2 liter cans and has a shelf life of 2 years. In spring, all fruit and berry crops from wintering herds of scale insects can be treated with an emulsion, spider mites, leaf rollers, suckers, moths and other pests. And in the summer to spray the trees and ornamental shrubs from vagrants of the first and second generation of scale insects

Nitrofen is a drug against the wintering stages of pests and diseases. This paste brown colorpackaged in cans or glass jars or polymer bottles. The shelf life of nitrophene is 2 years. It behaves well as a disinfectant for wounds on fruit trees.

Trees processing with copper sulfate

Before spraying, you must first clean the trunk of lichens with a brush. When processing trees, you can use hand pump, they are sold in specialty shops for the garden and vegetable garden. But it is desirable to have an automated sprayer. It is much more convenient and easier to work with. For those gardeners who already have mature trees, you need to have one that can be lengthened different ways... Most likely, you will have to tie it to a stick so that you can reach even the topmost branches or use special telescopic rods.

It is worth worrying about your own safety. Bathrobe, gloves, hat and glasses. These items will protect you from getting the solution on bare areas of your body. And the respirator will not allow the vapors of the solution to enter the upper respiratory tract.

Before starting treatment, the solution must be stirred. This is done as follows: 100 g of copper sulfate is diluted in a bucket of water. Vitriol dissolves worse in cold water. Therefore, you can breed it at home in hot water, for example, in three-liter can, and then pour the contents into a bucket.

The solution must be poured into the sprayer through a funnel and several layers of gauze. You must filter the content. This is to prevent the spray nozzle and hose from clogging up with undissolved particles. Now you should pump air into the balloon, hang it on your shoulder and forward.

This article describes the process of treating trees with copper sulfate. But you can use any means that you like best or have already been purchased. Each package contains detailed instructions how to use it.

How to properly spray trees

Wood processing must be carried out carefully from all sides. The jet must be directed from the edge to its central part. It is best to do this in turn with each major branch. Only in this case is it possible to achieve the maximum effect.

Remember to spray the ground around the tree. If last year's leaves are still on it, they will rot much faster. Also, with the help of the solution, spores of harmful fungi or the pests themselves will be destroyed. The remaining solution can be used on nearby shrubs, grapes, or other plants.

After you process the trees, you must carefully rinse the apparatus with water. To do this, pour into the sprayer clean water and chase her away. In this case, nozzles and hoses will not become clogged by remaining dry mortar particles. Change your clothes and be sure to wash your hands and face with soap.

What is needed for spraying trees and shrubs

Also, in early spring, trees can be treated with combined means. They will help you deal with several types of pests at once, which will allow you to avoid multiple spraying cycles of trees and fertilize the plant at the same time. An example is urea. You can learn about this from our other materials.

In order for the work on spraying trees to be carried out efficiently and have good efficiency, it is necessary to have everything necessary tools and fixtures.

Fruit and roses - can be used to combat root bacterial cancer; immersion of roots after removal of outgrowths for 2-3 minutes in a 1% solution of copper sulfate, followed by washing with water. Spraying should be carried out in dry, calm weather. fungal diseases did not penetrate into the trunk of the tree very deeply, in the fall it is necessary to prepare the apple tree for wintering.The next treatment of apple trees from pests in the spring is carried out after the appearance of the buds, but before the appearance of the leaves, a contact preparation is used for this, such as Treatment of apple trees in spring

Instructions

• - the weather should be dry and calm; At the first hints of a disease (the appearance of brown spots on the leaves and stems of bushes), the soil is spilled with a 0.5% solution of copper sulfate (50 g / 10 l). Consumption - 3.5-4 liters per plant.This event should be carried out before the buds swell and burst, in order to remove overwintered pest larvae and protect plants from insects and infectious diseases.
• In the calendar summer cottage works every owner personal plot plans measures for treating plants with insecticidal and fungicidal compositions, because there can be no question of any good harvest if the plants are sick or die from dangerous insects. Make sure that the expiration date of the chemical has not expired. It is recommended to process plantings in dry weather, during which time you can not eat, drink or smoke.

The use of copper sulfate in the garden and vegetable garden

Effective use of copper sulfate in the garden and garden beds

If signs of disease appear on trees and shrubs, it is advisable to spray with a solution of copper sulfate in late autumn (end of October - November), when the foliage will completely fall off. Trees are prepared in the same way as before spring processing... This treatment also destroys the larvae of pests that were laid by insects in cracks, depressions and bark for wintering.

In this case, a 1% solution is used (100 grams of crystals in a standard bucket of water). Spraying consumption from 2 to 5 liters for each tree, depending on its size and age.

To fight garden pests and fungal diseases of cultures, there is a proven remedy - copper sulfate - an inorganic compound that is a salt of copper sulfate. The composition is a crystalline granules of a saturated bright blue color, soluble in water. Copper sulfate solution is an excellent fungicide, antiseptic, insecticide and fertilizer.

Vitriol a. For spraying apples, pears and quince, dilute 100 grams of copper sulfate in 10 liters of water. Spray trees until buds appear and bloom with two to five liters of solution per tree. When spraying apricot, peach, plum trees, as well as cherries and cherries, 50-100 grams of copper sulfate are taken for ten liters of water. For one tree, the consumption of solution is two to five liters. Gooseberries and currants are treated with the same solution as apricot and peach trees, but with a consumption of one and a half liters per bush.

Copper sulphate + slaked lime + water-means for spraying fruit trees and shrubs from scab

After all the leaves fall off the tree, it is necessary to carry out preventive treatment against pests; for these purposes, it is best to use iron vitriol, a solution of sodium chloride or a solution of urea.

1. Processing of pears, apple trees and quince

... This drug kills pests when it comes into contact with them, and also promotes the penetration of substances poisonous for insects into food.

2. Processing stone fruit trees (plum, apricot, cherry plum, cherry, sweet cherry, peach)

In this article, we will look at caring for an apple tree, the most common fruit tree.

3. Processing berry bushes (all types of currants, gooseberries)

4. Disinfection of seedling roots in order to prevent bacterial and fungal diseases

- before dilution, make sure that the shelf life of the drug has not expired;

5. Tillage

Use a 0.5% -1% solution of copper sulfate (50-100 grams of composition per bucket of water). Consumption as in the previous recipe.

6. Processing of planting material

Actively used

7. Treatment of tomato beds against late blight

But making sure that there are no animals or children nearby. During the treatment of plants with a solution

In early spring, plants are sprayed to fight against fungal diseases, the consumption of copper sulfate is 100 grams per ten liters of water. Disinfecting the roots of seedlings, they are dipped into a solution of copper

Rules for working with copper sulfate

... They can process both trees and shrubs of fruit and berry plants. Copper

Dilute according to the instructions and be very careful with this drug, spray against plant diseases, from phytophthora and from scab, rust of coccomycosis, when leaves curl, it means there is not enough copper, copper sulfate is a necessary trace element for plants

Paying attention to the trees in the fall will allow them to spend the winter safely and also reduce the amount of spring work.

The third treatment is carried out after the appearance of foliage, for this, systemic drugs are used, for example

First treatment - spraying apple trees iron vitriol, and the next one should be carried out with contact preparations of the Actellic type, the third treatment is carried out already with systemic ones of the Aktara type, the fourth treatment with benzophosphate or carbofos. Next, we take a closer look at the schedule for spraying apple trees against pests.

- after the end of the event, wash thoroughly with soap and water, rinse oral cavity clean water.

- it is imperative to observe precautions, as in contact with any chemicals, protect the skin of the hands with gloves, the mucous membrane of the eyes with glasses, and the respiratory system with a respirator;

The solution is prepared in the same way as for stone fruit trees... Consumption - about 1.5 liters for each bush.

Apple tree: processing - spraying in spring

Copper sulfate is not a top dressing, but a medicine. Mostly from fungal diseases. It is part of the so-called Bordeaux liquid. The proportions are for a bucket of water matchbox vitriol and 200 grams of lime. You can spray all crops - from fruit trees to perennial flowers. But spraying is so effective on bare, non-leafy plants, that is, until the buds swell, since the spores of the fungus hibernate in the scales of the buds. After the leaves have opened and flowered, you can repeat the processing of the fruit if you notice signs of fungal diseases. It is undesirable to process during flowering fruit and berry crops... Wait for the flowers to fall and then ...

Copper sulfate - a fungicide intended for spraying fruit and berry decorative trees and shrubs from scab, moniliosis, anthracnose and other diseases in early spring before bud break, as well as for disinfection of fruit wounds.

When to spray apple trees from pests?

- during the work, it is strictly forbidden to eat, drink any liquids and smoke;

1. The roots of trees and bushes are dipped in 1% composition for 3 minutes.
2. For spraying shrubs and fruit trees, soil cultivation, combating diseases of vegetable and berry crops. The most effective time for events using copper sulfate is early spring. The concentration of the solution depends on the specific purpose and the type of plant. Subject to the technology and dosage, the copper sulfate solution is not toxic to plants and pollinating insects, and also does not directly affect crop rotation.And the air temperature should not exceed thirty degrees Celsius. After finishing the treatment of the plants with the solution, wash your hands thoroughly with soap, wash your face and rinse your mouth well for three minutes.
3. Is a copper sulfate salt. Its use is especially effective once every five to six years, in early spring. Consumption in this case will be one gram per square meter Recently I saw how to properly feed fruit crops - at a distance of 1-1.5 from the trunk, dig deep square depressions, pour the top dressing there and again cover with earth and grass! When using copper sulfate in agriculture, feeding is carried out 3-4 times per season by spraying the plants with a working solution at the rate of 1 teaspoon (5 g) / 10-15 liters of water. Autumn spraying fruit and ornamental trees and shrubs (after the leaves have fallen) or early spring spraying before bud break is carried out with 3% working solution at the rate of 30 g / 1 l of water.

... The next treatment is intended to combat the apple blossom beetle. It is carried out during the appearance of buds; for this, benzophosphate or karbophos preparations are used. When the bud turns pink, it is advisable to treat the tree from the caterpillar with dendrobacillin or bitoxibacillin preparations.

How to spray apple trees in the fall?

The first treatment is carried out before the buds dissolve. Moss and damaged bark are removed from the tree, diseased branches are cut down, and then the cuts and wounds on the apple tree are treated with copper sulfate.

The use of copper sulfate in the garden

- remove pets and children from the site;

If necessary, disinfect the soil in the beds or in greenhouses and greenhouses, spill it with a 0.5% solution (50/10 l). Consumption 2 l / sq. meter.

Expert gardeners a question for you, tell me?

Svetlana

The first treatment is carried out in March, when the average daily temperature indicators set at + 5 ° C and above. Before spraying, trees are prepared as follows: removing (cutting) old, damaged, diseased branches, cleansing the trunk and skeletal branches from lichens and dead lagging bark, sealing cut and cracks with garden pitch, cleaning the area under trees (removing litter and plant debris). In the meantime, there is no need to worry about it. ”

Good afternoon, dear friends!

Also disinfect the soil, the consumption in this case will be five grams per ten liters of water. Spray potatoes before direct sowing, making a solution in the consumption of copper sulfate - 2 grams per ten liters of water. The drug, when diluted correctly, is not phytotoxic, does not affect crop rotation, and is low-toxic to bees.
Depending on the plant and disease, different concentrations of copper solution are used

Gimera Dobroslovova

Copper sulfate is used in horticulture as a fungicide / against fungal diseases /. If your plant lacks copper, purchase fertilizers with trace elements and make a root or foliar feeding... Copper sulfate is not used as a fertilizer.

running on the waves

Recommendations for use: apple, pear and quince - early-spring spraying before bud break at the rate of 100 g / 10 l of water to fight diseases - scab, phyllostictosis and other spots, moniliosis and drying out. For apricot, peach, plum, cherry and sweet cherry - early-spring spraying before bud break at the rate of 50-100 g / 10 l of water, copper sulfate can be used to fight diseases - coccomycosis, curliness, clusterosporiosis, moniliosis.
