Agrospan protects radish from flea
Agrospan protects radishes from cruciferous flea

Although radishes do not have as many pests and diseases as, for example, tomatoes, they do exist and can destroy most of the crop. This article is an addition to great material about growing radishes.

It helps in the fight against diseases the observance of crop rotation on personal plot. Since radish is an early ripening crop (harvest can be obtained in about 1 month), there is a temptation to return to the same bed with re-sowing after some time in the same season. Doing so is highly undesirable. Because it can lead to outbreaks various diseases. It is also highly undesirable to plant radishes after cabbage or other cruciferous plants. Good predecessors are onions, garlic, peas, beans, potatoes, tomatoes, cucumbers, zucchini, zucchini.

Pests

The main scourge of radishes is cruciferous fleas - small bugs, usually dark in color, jump well from place to place. They damage radish leaves (make holes in them). And if the damage to the leaf apparatus of the plant reaches a critical size, then the plant abruptly stops growing and may die. At the same time, the root crop does not ripen and does not grow to the desired size. Radish seedlings should be especially protected from fleas. Otherwise, crops can be completely destroyed (eaten). mature plant can still tolerate fleas to some extent. Fleas are especially rampant in dry, hot weather. Early crops of radishes can generally produce a crop before the mass appearance of cruciferous fleas.

The fight against the flea should be carried out by biological methods.
The first way is spraying on the leaves with a solution wood ash. The solution is prepared as follows: about 2 cups of preferably fresh ash and 50 grams of laundry soap are added to a 10-liter bucket of water. Everything is mixed up. Some make it easier. They collect ashes on a shovel and crush them over the garden. For a while, the flea restricts its malicious activity.

The second way is the same. Only instead of ash they take tobacco dust. It should be said right away that tobacco dust still needs to be looked for in stores, and it costs, although not expensive, but still worth it. And the ash is usually its own, free.

All these methods are still not effective enough. The most effective is insecticide treatment, such as Inta-Vir. But this should be done only as a last resort, only for medium-sized radishes (ripening time 25 days) and only for young seedlings, if the threat of destruction of crops is large enough.
Another exotic (mechanical) way to deal with the cruciferous flea is to cover the radish with white agrospan right on the seedlings. If the weather is not too hot, then the shoots under it do not stretch out and there are no fleas there. After the seedlings have grown stronger, we remove the non-woven covering material and fight further with ash.

Important note. It is desirable to transfer radishes to drip irrigation. Otherwise, all efforts to combat the flea with the help of infusion on the ashes will be in vain after the first watering on top of the leaves. The infusion is washed off the leaves, and the flea gets back to work.
Another note. If they grow next to radishes cultivated plants and weeds of the cruciferous family, then all the surroundings can be treated with chemistry.

Belyanka is another radish pest. Belyanka is white butterfly with dark wing edging. But the leaves of the radish are eaten by its caterpillars.
When dealing with whitefish, it is also desirable to do without the use of chemistry. The beds must be treated with a solution of mustard, salt and ground pepper. It is prepared like this: for a 10-liter bucket of water - 2 tablespoons of mustard, 2 tablespoons of salt and 1 teaspoon of red or black pepper.

Radish diseases

Bacteriosis. Root crops become slimy, begin to emit a smell of rot. At the same time, the leaves of the radish turn yellow.
To combat this disease, plants are treated with 1% Bordeaux liquid.

Keela. Blisters and outgrowths appear on the surface of root crops, radish leaves begin to turn yellow and wither.
To combat this fungal disease, the soil around damaged plants is watered with milk of lime. Prepare it like this: in a 10-liter bucket of water, dissolve 2 cups of fluffy lime. One plant must be watered with 1 liter of solution.

Blackleg. Young radish plants can be affected by blackleg. The leaves curl and turn yellow, blackening appears at the base of the plant stem.
To combat the black leg, prepare the following solution: dissolve 1 tablespoon in a 10-liter bucket of water blue vitriol and 40-50 grams of laundry soap shavings. Then the diseased plants are sprayed.
It is also very good to spray seedlings with tincture of onion peel(approximately 20 g per liter, leave for 1 day).

When choosing varieties of radish for planting, preference should be given to resistant varieties to various diseases.
But once again we can repeat that it is better to take precautionary measures. And then the probability of diseases will decrease sharply.

Radishes grow well in middle lane. Gardeners harvest several crops per season, using several varieties. And although the plant has not so many pests, you should not lose vigilance and fight them.

Radishes are the best early varieties. Seeds are planted in the soil until the spores of fungi and larvae are activated, so the fruits form and ripen without much difficulty. It is more difficult for vegetables of medium and late ripening, the growing season of which coincides with the intensive reproduction of harmful microorganisms and insects. They literally attack young shoots, wanting to drink all its juices.

Insects often attack weak shoots, so you should not ignore the introduction of fertilizers and dressings. Adequate nutrition strengthens the immunity of the plant, which means that the chances of catching a disease or infesting the beds with insects are significantly reduced.

damaged radish leaves

The likelihood of flea attacks is reduced if feeding is timely introduced into the garden from slurry. No less effective is the processing of their powder, which is made from wood ash and tobacco dust in equal proportions. It is necessary to carry out the procedures 1 time in 5-7 days.

Cruciferous flea on radish leaves

The white butterfly poses a danger to the radish by laying its eggs directly on the soil. The emerging caterpillars easily move to the leaves and eat them.

To protect radishes from whites, you need to spray with a solution of mustard (2 tablespoons), ground black pepper (1 teaspoon) and table salt (2 tablespoons) per bucket of water.

Small black bugs with bright orange stripes suck the juice out of the radish, causing the young shoot to dry out.

You can protect the garden from the pest if you spray it with an infusion of dope or henbane. The preparation of the working solution involves the infusion of 500 grams of leaves in a bucket of water for 12 hours. To keep the composition longer on the tops, it is recommended to add 2-3 tablespoons of crushed laundry soap.

Belyanka Cruciferous bug

In the second half of May - early June, the female rapeseed sawfly lays eggs. When choosing a place, preference is given to radish, located on the underside of the leaf. Already after 6-10 days, very voracious caterpillars appear from the eggs, which can make many holes in the tops of the plant and thereby kill it.

To protect the plant from this pest, you need to treat it with a special infusion of black henbane. For 500 grams of dry leaves, take 2 liters of water, you need to insist for at least 12 hours, after which the liquid is filtered through a sieve. The resulting infusion is diluted with 8 liters of water, grated soap is added and the beds are treated.

Prevent insect infestation preventive actions, which include autumn cleaning of the site and digging the soil.

Babanukha Rape sawfly

A small bug (body length no more than 2.5 mm) is black with a blue tint, perfectly tolerates frost in plant debris. In spring, it becomes active, laying eggs in unopened buds.

Among the important measures to protect radishes from pest damage:

• compliance with crop rotation;
• thorough autumn cleaning;
• introduction of fertilizers into the soil;
• selection quality seeds for landing;
• the introduction of top dressing to strengthen the immunity of plants;
• spraying with karbofos;
• treatment of beds with biological products (Dendrobacillin, Lepidocid, etc.).

Cabbage moth on a radish leaf

Young shoots attract insects. To protect them from the invasion of uninvited guests, it is recommended to carry out preventive measures. Among the effective methods:

• dusting plants with a powder mixture of naphthalene and road dust (1: 1);
• spraying powder from wood ash, slaked lime and tobacco dust on the beds (all components are taken in equal proportions);
• morning spraying with a solution of wood ash (for 3 liters of water liter jar ash and 2-3 tablespoons of crushed laundry soap);
• spraying seedlings with vinegar solution (1 cup of 9% vinegar per bucket of water);
• spraying plants with a decoction of green wormwood.

It is clear that one processing is not enough, therefore experienced gardeners practice weekly procedures that are repeated for 1.5 months.

When choosing neighboring plants, it is worth considering the option of planting marigolds, nasturtium, fennel, mustard and other repellents.

After each season, a thorough cleaning of plant residues should be carried out. It is in them that most of the pests hibernate. Closer to frost, the bed needs to be dug up so that the larvae and adults freeze out.

Attacking a plant, pests can destroy the entire crop in just a few days.

The defeat of the tops is especially dangerous - the growth of the root crop stops, and the plant dies.

How to determine what exactly hit the root crop - a disease or insects?

If a plant overcomes an illness, it changes its physiological state. Symptoms of various diseases can be:

• the appearance of a white oil coating on the stems, leaves, pedicels and testes;
• spherical growths on root crops, which eventually turn brown and begin to rot;
• black, light yellow or brown spots on radish leaves;
• root crops are covered with brown spots and overgrown with gray fluff;
• the veins on the leaves or the base of the stem turn black, the leaves turn yellow and begin to fall off.

The causative agents of diseases with such manifestations are fungi and viruses.

cruciferous flea

Black bugs moving in the garden with intense jumps making them easy to spot. The pest infects radish leaves, gnawing out fragments and quickly increasing the affected area. The attacked radish stops growing and dries up.

The cruciferous flea is especially active in dry, hot weather.

How to deal with a pest, how to treat a flea radish, are there folk remedies against this insect?

To protect landings from flea attacks, you can resort to natural remedy. For the manufacture of protective composition required in equal proportions:

1. Ash.
2. Tobacco dust.
3. Mix the components and scatter the resulting composition over the garden at intervals of once every five to seven days.

In case of mass destruction and the inevitable need for the use of chemicals use drugs Tod, Alfatsin, Zolon, Kaiser, Arrivo.

The plant is processed according to the instructions. For example, Zolon, a preparation in the form of an emulsion concentrate, is used as follows:

1. Spraying is carried out during the growing season.
2. The composition is diluted in a ratio of 1.6 ml per 2 liters of water. The resulting solution is enough to process about three square meters.
3. Processing is carried out in the morning or in the evening in calm, dry weather.
4. The duration of the drug action is 15-20 days, 90% of pests die on the third day after spraying.

Belyanka

White butterfly laying its larvae in the soil. The emerging caterpillars move onto the leaves and destroy them. To disinfect plants, you need to prepare a composition of the following components:

1. Mustard - 2 tablespoons.
2. Ground black pepper - 1 teaspoon.
3. Table salt - 2 tablespoons.
4. Water - 10 liters.
5. Mix all the ingredients and spray the radish once a week.

Of the chemicals, Iskra M, Kemifos, Fitoferm are effective, they are used according to the instructions.

cabbage moth

A night butterfly of a gray-brown color, about two centimeters in size. Insect larvae can be found on the underside of leaves.. The hatched caterpillars feed on the leaves of the radish.

To counteract the pest, you need to feed the plantings with superphosphate with calcium chloride.

If there was a mass defeat of plants, then to destroy the pests, you will have to resort to chemical treatment Lepidocide and Bitoxibacillin, remembering that it is forbidden to carry out such treatments during fruit ripening.

Application of Lepidocide:

1. The drug is prepared on the day of use, according to the instructions.
2. To prepare the solution, only clean, warm water is used.
3. Spraying is carried out in dry weather up to +35 degrees.

cabbage fly

This gray-brown fly does not pose a danger to radishes, unlike its larvae. They deform the root, gnawing holes in it. Also, caterpillars are able to completely destroy fresh leaves.

The insect does not tolerate substances based on naphthalene, slaked lime and camphor. Plants can be treated with formulations that include one of the listed components.

If the lesion exceeds 15%, Lepidocid and Bitoxibacillin are used.

garden scoop

Butterfly brown color, the larvae of which eat seedlings. As a result of such a lesion, the greens can grow, and the fruit does not develop, and remains a root.

To destroy the pest, you can use the following recipe:

1. 500 grams of dried tops.
2. 50 grams of grated laundry soap.
3. 10 liters of water.
4. Leaves to insist in water in a warm place for four hours.
5. Add soap before spraying.
6. Process landings in the evening in dry weather.

If a remedy made from natural ingredients does not work, you need to use chemicals. Well proven Zeta-cypermethrin, IntaVir.

IntaVir solution is prepared at the rate of 1 tablet per 5-10 liters of water. Processing is carried out through a sprayer.

cabbage butterfly

A white butterfly whose caterpillars feed on young leaves and eat away the flesh, leaving only veins.

You can overcome pests by collecting them manually and processing the landing coniferous concentrate. For this you will need:

1. Spruce or pine branches and cones - 200 grams.
2. Hot water - 2 liters.
3. Put the raw materials in an enameled container, fill with water, leave at room temperature for a week.
4. After the set time, strain the remedy.
5. Dilute in a ratio of one part concentrate to ten parts water.
6. Spray in the morning every two weeks.

If there is a need for processing chemical compounds, then Fitoverm, Bitoxibacillin and Lepidocid are well suited.

wireworm

small, brown bugs with oblong bodies. Destroy tender shoots. Adults feed on leaves, while larvae feed on root crops.. On plants attacked by a wireworm, rot and all kinds of fungal diseases. Radishes rot from the inside.

A good option for saving from a wireworm is to bury the onion peel in the garden when.

At the first symptoms of damage, fertilization based on ammonium sulfate can help.

If the plant is massively attacked, use the drug Bazudin. To destroy the wireworm, it is introduced into each well, at a dosage of 1 gram per square meter.

stem nematode

These are filamentous microscopic transparent whitish worms, up to 2 mm long. Their goal is radish juice, they can nest in the root neck of the fruit, roots or stem. Damaged radishes wither and die.

Marigolds are effective against nematodes:

1. The whole plant is dried in the open air.
2. Half a bucket of crushed marigolds is poured with ten liters of water and insisted for three days.
3. 50 g of laundry soap is added to the resulting composition, the solution is filtered.
4. It is necessary to spray the plant weekly.

To combat nematodes, insecticides are used: Dimethoat, Rogor, Vidat. The use of these drugs makes sense only for young seedlings.

Plants are treated by spraying in the morning or evening hours. To achieve the best effect, choose a warm, calm day.

Rape sawfly

Insect, about 8 mm long, yellow-orange in color with two black spots on the back. The body is shiny with two pairs of transparent wings, yellow at the base and with a black border around the edges. The female rapeseed sawfly lays eggs in the second half of May - early June on the underside of the radish leaf. Hatched caterpillars eat numerous holes in the tops and lead the plant to death.

An infusion of black henbane will help in the fight against the pest. You need to take:

1. 500 grams of dry leaves.
2. 2 liters of water.
3. Insist 12 hours.
4. Strain the liquid through a sieve.
5. Dilute the resulting composition with eight liters of water, add grated soap and process the beds.

Of the chemicals, Dendrobacillin and Entobacterin are effective.

Entobacterin is dissolved in warm water, adhering to the dosage of 10 g per liter of water. Processing is carried out using a spray gun.

cruciferous bug

Small black bugs with bright orange stripes feed on radish juice and young shoots dry up. To protect plantings from pests, you can prepare the following solution:

1. 500 grams of Datura leaves.
2. 10 liters of water.
3. 2-3 tablespoons of crushed laundry soap.
4. Mix the ingredients and leave for 12 hours.
5. Spray the tops every five days.

For chemical treatment, Phosbecid, Aktellik are used. The drugs are used according to the instructions.

summer cabbage fly

Wormy radish fruits - the result of the vital activity of the summer cabbage fly. Harmful insect larvae are difficult to detect - they are whitish, up to 8 mm in length. Destroy inner part stems, make moves and move towards the fruit.

A folk remedy in the fight against this insect includes:

1. Salt - 200 grams.
2. Ten liters of water.

Salt is diluted with water and the beds are watered. After the earth needs to be sprinkled with ashes.

Effective insecticides in the fight against summer cabbage fly - Karbofos, Zemlin, Rovikurt.

Prevention

To prevent the appearance of pests, you can also carry out the following procedures:

• spray on beds with radishes taken in equal proportions wood ash, slaked lime and tobacco dust;
• spray radishes with a decoction of green wormwood;
• spray only emerging shoots with a solution of vinegar, prepared at the rate of 1 cup of 9% vinegar per ten liters of water.

At the end of the season, you need to clean up plant residues, since it is in them that some of the pests hibernate. Closer to frost, the earth in the garden needs to be dug up so that the larvae and adult insects die.

Proper crop control, pest prevention and, if necessary, timely destruction measures taken will help the gardener win the fight for a rich radish crop.

Gardeners appreciate radishes for tasty and healthy root crops that they look forward to. However, in some cases, the harvest can significantly and a short time spoil the pests called cruciferous flea. These little bugs bring a lot of trouble. How to save seedlings and get rid of insects, we'll talk in this article.

What is this pest?

The cruciferous flea damages mainly plants of the cruciferous family, which is why it got its name. The flea has hind legs, on which it jumps like a flea, but it is not a blood-sucking insect. The bug prefers to settle on such weeds as wild radish, shepherd's purse, from horticultural crops especially fond of turnips and cabbage. However, radish remains a favorite delicacy in the early stages of the pest.

The insect has very small dimensions, the length of its oval oblong body is up to 3 millimeters. At the same time, the flea can fly. There are several varieties of the pest, among them are black, blue, light-footed and others. The differences are determined for the most part by the color of the elytra.

Beetles live in the European part of Russia, excluding the regions of the Far North. The harm from the insect is expressed in the fact that it damages the leaves, in which it gnaws out peculiar pits. The flea is especially dangerous for young greenery, as it can gnaw through tender leaves. Thin roots of crops serve as a delicacy for larvae. Pests are most active during the day, except for the period from 13 to 16 hours, when the sun is especially scorching.

V winter period an adult flea hides in the remains of plants, crevices of greenhouses, soil. When spring comes and the ground thaws, the insects come out and begin to actively seek food for themselves, after which eggs are laid. The cruciferous flea larvae live in the soil for about 3 weeks, after this time they pupate, and new young individuals come to the surface. An insect can give birth in a whole summer period up to 3 generations.

Prevention measures

It is easier to prevent any problem than to deal with its consequences later. Therefore, experts and seasoned gardeners recommend several prevention methods that will help protect radishes. Consider. what needs to be done to protect the plantings from the pest at the initial stage.

The proximity of coriander, dill and garlic repels the pest, as the insect really does not like the smell of these plants. In the case when radishes are planted towards the end of the season, it is recommended to place the beds next to calendula or marigolds, which the flea also does not tolerate.

Fighting methods

In order to get rid of the cruciferous flea, you need to make sure that the crop is harmed by an insect of this particular species. This is not so difficult to do, because despite the small size of the pest, it can be easily detected visually. The bugs jump on the leaves, which have gnawed holes.

The main danger of a flea is that in the absence of a fight against it, the gardener can completely lose seedlings. Since radishes often appear earlier than other sprouts, it is on it that the main blow of the bugs that become active after hibernation falls. In addition, a large number of these insects can harm adult plants, as well as even hardened radish seedlings, so protection measures should be started as early as possible.

Start with prevention and deterrence, chemicals are used as a last resort.

Folk remedies

Not all gardeners accept the use of chemicals. In some cases, they are quite effective folk methods, however, when using them, it must be taken into account that in this case it is not enough to process the crops once or twice, systematic care will be required, which, accordingly, involves a large investment of time. There are several of the most common folk methods, the excellent effect of which is confirmed by a huge number of examples:

• humid environment;
• dry pollination;
• shelter nonwoven fabric;
• setting traps;
• spraying infusions.

Let's take a closer look at these methods.

Wet environment

The red-colored flea thrives in hot and dry weather, but it does not like humidity. Therefore, when planting, it is recommended to choose the most humid part of the garden. Abundant watering will also scare away the pest. At the same time, do not forget that he is afraid of strong odors, so it would be useful to add strong-smelling products to the water.

dry pollination

Plantings can be pollinated various means, since the bug chooses the cleanest leaves for food. This method is very popular among gardeners, as it does not require large financial costs and is very effective. Mixtures can be different, the most commonly used is ash in combination with tobacco or road dust, as well as fluffy lime.

The components should be taken in equal proportions and mixed thoroughly. The procedure itself is recommended to be carried out early in the morning so that the composition lies on the dew, and you also need to water the radish first. In humid conditions, the particles of the mixture adhere well to wet leaves. For the most effective and uniform result, the composition is placed in a gauze bag, after which it is gently shaken over the sprouts. This method is also called powdering.

Minus this method in that it does not work with a single use. good protection can only be ensured if dusting is carried out systematically.

The ideal option would be when the gardener can carry it out after each watering or rain. And also, to achieve the maximum effect, crops should be processed not only from above, but also from below.

Shelter with non-woven material

If the crops are covered with a cloth, they will be protected not only from insects, but also from weeds and cold weather. The material must be chosen wisely, it must pass light, water and air, but at the same time be an insurmountable obstacle to pests. Well suited, for example, lutrasil or spanbond.

In addition, many recommend dusting radishes before shelter, which will serve additional protection. When under such a canvas, the radish will grow, get stronger, the leaves will coarsen a little, so when the shelter is removed, it will no longer be an easily accessible and especially attractive delicacy for a flea.

Traps

The use of a sticky flag is often used to help get rid of the pest. The procedure is quite simple and does not require special skills.

To make a flag, a piece of fabric is attached to a stick and treated with some kind of adhesive. Solidol is excellent for this purpose. After that, you need to go along the beds with radishes, slightly touching the flag with its leaves. This will disturb the insects, which will try to hide from danger, and, flying away or jumping, will touch the material and stick to it.

Gardeners advise to carry out this procedure in the middle of a dry and hot day, while repeating it several times, maintaining small time intervals. Such catching fleas will help to significantly reduce the number of insects in the beds.

Another trap is made using used engine oil, in which a piece of cloth is wetted. Boards are laid out along the beds with radishes, on which the impregnated fabric is laid. To as much as possible more insects trapped, the material needs to be turned over a couple of times a day.

Spraying with infusions

Infusions can be made on the basis of various components. For example, ash and tobacco dust, which are used in dusting, are suitable. There are many popular recipes, each one selects the simplest and most effective in a particular case. Let's take a look at the most common ones.

A glass of ash is poured into one liter of boiling water, mixed and left for 48 hours. After that, rub laundry soap and add it to the infusion. You can also use liquid soap. Radishes are sprayed with this composition.

A glass of tobacco dust should be poured with a bucket of boiling water and left for 24 hours. After that, 100 grams of soap is added, and the infusion is filtered through gauze.

Garlic should be crushed. Stepsons of tomatoes are added to it. The ratio should be 1: 1. The mixture is poured with warm water and infused for 5-6 hours, after which it is filtered, and a little liquid soap is added to the resulting infusion.

Agrotechnics for growing radishes

General information. Varieties of radish.

For the same reason, tansy or celandine can be planted along the perimeter of the garden;

should be applied at least once a week

A young radish will be a real find for them. Watering when planting in April is not necessary - the ground is still quite wet. You can pre-cultivate the land hot water. When re-planting radishes, watering is essential.

Almost everywhere.

Against these pests, it is recommended to use pollination with wood ash or tobacco dust. sown in early dates radish helps prevent plant damage. Hot, dry weather contributes to the emergence of diseases and pests.

1. Before planting, the seeds can be held in a damp cloth so that they hatch. To protect against dry rot planting material heated for 15 ... 20 minutes in heated water (about 45 ° C). This procedure also contributes to more early appearance seedlings.​
2. Early ripe varieties (vegetation period 25 ... 30 days). Here you can select such varieties as "Dawn", "Ruby", "Rose-red with a white tip", "Camelot", "Cherry Belle", "Early Red" and others.
3. Radish is an early vegetable crop that begins to produce one of the first crops. Juicy, spicy-tasting fruits are incredibly healthy and tasty. They can be used for salads, okroshka and other dishes. Radishes are often attacked various pests, which can destroy the crop in a matter of days or seriously spoil it, making it unfit for human consumption.
4. Dealing with them is quite simple (and of course, without using pesticides that will not decompose before cleaning and with which you will “treat” your family).

Soil preparation before planting

She jumps from leaf to leaf and makes holes in the leaves.

You can also make a distracting maneuver by planting a weed loved by a flea next to a radish;

. And as an option - ground black pepper or slaked lime. ​.​ The quality of radishes is proportional to the regularity of watering. Without water, radishes are not as juicy and large, more bitter. On hot days, radishes are watered every evening, on cool days - once every two days.

The benefits of radishes Radishes have a lot of useful properties. It improves appetite and metabolism, strengthens the immune system, lowers blood cholesterol levels, removes toxins from the body, and even, according to some reports, stops growth. cancer cells. Guys - this is fiber - Dr. Aibolit for our body.

Preparing radish seeds for sowing

To prepare a working solution, add about 2 cups of fresh ash and about 50 g of laundry soap to a 10-liter bucket of water. Mix everything thoroughly. You can pick up ash on a shovel and crush it over a bed with crops. For some time, insects will limit their harmful activities.

You can sow radishes in the country from mid-March, as soon as the soil thaws to a depth of about 10 cm (when growing radishes in a greenhouse, sowing can be done much earlier). The agricultural technique of growing radishes involves sowing seeds in rows, deepening them by 1 ... 2 cm. It is not recommended to sow deeper, as there is a risk that the root crop will not tie. Optimal distance between rows is considered 8 ... 10 cm. For planting beds of 10 square meters. m will need about 15 g of radish seeds. There are about 1000 seeds in 10 g.

Optimal sowing time

Mid-season varieties (vegetation period 30 ... 40 days). Varieties "Mokhovsky", "Heat", "Icicle", "Red Giant", "Virovsky White", etc.

plant care

Most often, cruciferous fleas attack radishes, which in a short period of time make many holes in the tops. All this negatively affects the yield. Fleas have absolutely small size bodies with pronounced metallic sheen. As a rule, insects are one-colored. spring cabbage fly, despite its name, spoils the radish. Females lay eggs in the soil, from which larvae 6-8 mm long gray or white flowers. The larvae move closer to the roots and begin to actively eat them. Over time, they spread to the stems. If no action is taken, the crop will be spoiled. The rapeseed bug feeds on absolutely any cruciferous plants, including radishes. Since the bugs hibernate under the foliage, they are activated immediately after warming. Females make clutches directly on the foliage. Damaged plants turn yellow and wither. The main thing is to carefully clean the garden in the fall. The fewer last year's leaves, the lower the likelihood that pests will appear in large quantities. But this, unfortunately, is not always enough. Cabbage moth, leading a nocturnal lifestyle, feeds on cabbage, radish, turnip, and also gladly absorbs plantings of turnip, watercress, horseradish and radish. The moth has the appearance of a small butterfly, the wings are brown with stripes. Cabbage moth caterpillars eat leaves in large quantities. Slugs live on cruciferous plants, especially on young ones. Pests spoil mainly the foliage of radishes. Slugs live for a long time, and they reproduce quite well, which is why it is important to process planted crops on time. Manual collection of slugs will not give the desired effect, because they can migrate from garden to garden, thereby spreading to large areas. Clickers or wireworms eat all root crops, including radishes. Since their presence is often ignored by summer residents, significant damage is noted upon harvest. In some areas, there is a huge number of pests that look like orange thin worms, somewhat reminiscent of copper wire.

Ordinary ash, which can be collected after cooking kebabs or specially burned a small bonfire of stick branches, is sprinkled in the early morning (on the dew to stick to the leaves), radish crops and the flea are retreated in a hurry.

It also gnaws on young shoots of radishes and root crops.

Postpone the planting date of the crop to an earlier time (immediately after the snow melts);

Radish pests and their control

Spraying gives good results

Transforming then into an imago, the insect eats the tops. The flea eats the tender leaves of the radish to holes, as a result of which they dry out. There, on the leaves, beetles lay yellowish eggs.

A few days after germination, the radish is thinned out. The thickening of crops is one of the reasons for the shooting of radishes. Do not regret - pull through!​

Radishes can be sown at several times with an interval of 10-15 days.

When growing radishes, it is best to use drip irrigation systems, as abundant watering after treatment against pests will wash off the protective composition.

To get friendly and strong seedlings, the soil must first be watered. When the first true leaves appear, it is necessary to thin out the plants. The distance between the shoots should be 2-3 cm. Experienced gardeners they suggest that it is better to plant one seed at a time, since when thinning, the root of the plant left behind can be damaged, after which it develops worse and can go into the arrow, which will significantly affect the yield.

Late-ripening varieties (vegetation period of more than 40 days). This group includes varieties "Dungansky", "Zenith", Rampoush.
