A detailed description of the pests of radish and methods of dealing with them. Description of pests of radish (radish) and the fight against them Radish in holes

Smooth, bright marketable radish evokes joy and pride in the work done on the site. But a tasty root crop is liked not only by people, but also by insects, so it is not always possible to get a beautiful harvest. There are many pests that can spoil the radish, destroy its tops or pulp. If you do not fight them, they will quickly spread, filling the site. The article will describe the pests of radish and methods of dealing with them.

Signs of pests on radishes

It is even easier to notice pests on radishes than diseases, because they are visible with the naked eye, and if we are talking about underground pests, then it will help to determine appearance tops or dug up root vegetable. There are several main signs of the appearance of pests:

ulcers on the leaves;
twisted, yellow leaves;
black formations at the base of the sheets;
for no reason sluggish, drooping tops;
leaves in holes that could not appear in any other way, except from caterpillars and other pests;
holes and tunnels are visible on the radish itself.

In particular, you need to watch out for young shoots of radish. They are very vulnerable and if pests attack them, you can lose the entire crop!

Insects usually eat the leaves immediately, although underground ones can start from the root or root vegetable, so you need to be careful. And at the first sign, retaliate.

The main pests of radish

Radish pests do not appear spontaneously in the garden. They usually switch to radishes from other crops or from weeds that are on the site.

Cabbage white is a butterfly white with a black border along the edge of the wing. She lays eggs in areas where radishes grow, and the caterpillars hatching from them eat the bases of the radish leaves. This leads to the fact that the root crop stops growing and may simply not grow.
The cruciferous flea is one of the most dangerous enemies radish. She eats still young leaves of radish, gnawing holes in them when they first appear. After their invasion, the planting bed resembles a sieve.
The wireworm is a pest known to any gardener. This is the larva of the click beetle, which can destroy the entire plant - the ground and underground parts in a short time.
Cabbage and garden scoop are gray-brown butterflies that also leave clutches on radish leaves. The larvae that appear from them eat the leaves, while only transparent skeletons remain from the green tops. Of course, root crops in the ground stop developing completely and dry out or rot.
The cabbage moth is a gray-brown insect with a distinctive fringe on its wings. The moth itself is not harmful to the radish, but its larvae suck the juices from the tops and eat the leaf tissue.
The spring and summer cabbage fly is an ash-colored insect (the summer fly is usually larger than the spring one). Among the plantings of radishes and other vegetables, she lays eggs, and the white larvae (worms) hatching from them penetrate deep into the ground and eat the roots of the radish. Within 2-3 days the radish becomes unusable.

As you can see, there are a lot of pests that threaten radish. But if you know how to deal with them, you don't have to worry about the crop or its quality.

How to deal with radish pests?

When the gardener has recognized a pest encroaching on the area with radishes, you can begin to exterminate the pests. There's a lot specialized drugs, which very effectively cope with their task, but they must be used exclusively according to instructions, during that period of culture development, when they cannot harm the crop.

« Actellik "- a well-known drug effective against cabbage flies, cabbage whites, scoops. For 10 liters of warm water, 20 ml of the substance is taken, mixed well and used for spraying. This solution is sufficient for 10 squares of planting.
« Entobacterin " - strong, biological product from cabbage moths, aphids, cabbage whites. It is used dry (for dusting) or liquid (for spraying). Diluted according to the guidance provided on the package.
« Zolon "Used for cabbage whites, midges, scoops, aphids, cruciferous flea... The method of use is indicated on the package.
« Zemlin »Can save the site from cabbage flies, wireworms and other insects that live in the ground. Diluted according to the rules on the package and used immediately. You cannot cook this product for future use!
« Provotox "- a strong drug against wireworm, not addictive in insects, therefore it can be used annually. Divorced according to the instructions on the box.

Spraying or watering with insecticides is carried out only in dry weather. If it rains after using the insecticide, it is advisable to repeat the procedure, because the water washes away most of the insecticide.

« Aktara "- a universal preparation against various pests on cruciferous plants. He can remove caterpillars, larvae, butterflies, moths, aphids from the site. However, you need to use it carefully because it is also harmful to bees. Therefore, it is always used only according to the instructions and only when there are no flowering plants nearby.
« Initiative »Breeds wireworm, caterpillars, scoopers, cruciferous flea beetles, fly larvae, cabbage whites. One sachet (30 g) is sufficient for about 15 square meters plot. This remedy is being prepared atypically. It is not divorced with water, but mixed with sand. A ¾ liter jar is filled with sand, and then 30 g of the substance is poured there and mixed. The resulting composition is sprayed over the site.
« Bazudin »Copes with the invasion of bears, cabbage fly larvae, weevils, wireworms. To use, you need to fill in with ¾ liter jar sand, add 30 g of Bazudin and spray over the area with radishes. This amount is usually sufficient for 20 square meters of planting.

Folk methods of struggle

In the case when radish pests have just appeared on the plant, you can not immediately use strong ones, specialized means, and get along with folk remedies.

Ash soap. Dissolve 50 g of laundry soap and 2 glasses in a bucket of water (10 l) wood ash... The resulting composition is thoroughly mixed and used for watering radishes. This remedy copes with the cruciferous flea.
Mustard with pepper. If a mole, scoop, cabbage whitewash appears on the radish, you can scare them away with this remedy. A teaspoon of red powder is mixed in 10 liters of water, hot pepper, 2 tablespoons of salt and the same amount of dry mustard. Plants are watered with the resulting mixture.
Tobacco and ash drive away caterpillars, larvae, flea bees. One of these means or both, you just need to powder the leaves and the ground where the radish grows. This simple procedure will scare away pests.
Ash and lime in a 1: 1 mixture can drive away a horde of cruciferous flea beetles. But you need to use this tool only in dry weather, and repeat after rains.

Preventive actions

Every gardener knows what pests live on his site or lived earlier. In order to prevent their secondary appearance or damage to radish by them, it is necessary to carry out preventive measures.

The aisles should be clean - no weeds, fallen leaves, and it is also not recommended to thicken the crops.
Preventive spraying of crops allows you to avoid possible problems... But it is not necessary to use insecticides for this. If there are no pests yet, folk recipes will also be effective.

Interesting!

Insects are especially active during the hot season. And most of all they are attracted by young radish.

Any affected plants are best removed rather than waiting for the crop to recover. While the gardener is waiting, the pest is looking for new ones, delicious treats and switches to them.
Rot always attracts pests, so there should be no such odors on the site. Old mulch is changed in time, fallen leaves are burned, waste is thrown away.
Observance of crop rotation avoids pests. You cannot plant radishes after crucifers!
Watering should be done in moderation. An abundance or lack of moisture can attract insects for which such an environment is comfortable.
An acidic environment is liked by many pests, so you need to control the acidity of the earth and adjust it as needed.

As you can see, everything is not very difficult, the main thing is to take a comprehensive approach to the problem, if it has arisen. But, in general, with the observance of preventive measures and a timely response to the appearance of pests, the gardener may not worry about the radish harvest.

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

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

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

If a plant overcomes an ailment, it changes its physiological condition. Symptoms various diseases may be:

the appearance of a white oily coating on the stems, leaves, pedicels and testes;
spherical growths on root crops, which eventually acquire a brown tint and begin to rot;
black, light yellow or brown spots on radish leaves;
root crops are covered with brown spots and are 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 fragments and rapidly enlarging 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 radish from a flea, are there folk remedies against this insect?

You can use a natural remedy to protect the planting from a flea attack. For the manufacture of protective composition required in equal proportions:

Ash.
Tobacco dust.
Mix the ingredients and scatter the resulting composition over the garden bed once every five to seven days.

In case of massive defeat and the inevitable need to use chemicals use drugs Tod, Alfatsin, Zolon, Kaiser, Arrivo.

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

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

Belyanka

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

Mustard - 2 tablespoons
Ground black pepper - 1 teaspoon.
Table salt - 2 tablespoons.
Water - 10 liters.
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 gray-brown moth, about two centimeters in size. Insect larvae can be found on the underside of leaves... The hatched caterpillars feed on radish foliage.

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

If there is a massive defeat of plants, then to destroy the pests will have to resort to chemical processing Lepidocide and Bitoxibacillin, remembering that it is prohibited to carry out such treatments during fruit ripening.

Application of Lepidocide:

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

Cabbage fly

This gray-brown fly is not dangerous for radishes, unlike its larvae. They deform the root, gnawing holes in it. Caterpillars are also capable of completely destroying fresh leaves.

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

If the lesion exceeds 15%, use Lepidocide and Bitoxibacillin.

Garden scoop

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

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

500 grams of dried tops.
50 grams of grated laundry soap.
10 liters of water.
Insist the tops in water in a warm place for four hours.
Add soap before spraying.
Process plantings in dry weather in the evening.

If a remedy made from natural ingredients did not work, you need to use chemical means. Zeta-cypermethrin, IntaVir have proven themselves well.

IntaVir solution is prepared at the rate of 1 tablet for 5-10 liters of water. The treatment 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 fight pests by collecting them by hand. and processing the landing coniferous concentrate... For this you will need:

Spruce or pine branches and cones - 200 grams.
Hot water - 2 liters.
Fold the raw material into an enamel container, fill it with water, leave at room temperature for a week.
After the allotted time, strain the product.
Dilute one part concentrate to ten parts water.
Spray in the morning every two weeks.

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

Wireworm

Small, brown bugs with oblong bodies. Destroy tender sprouts. Adults feed on foliage, and the larvae feed on roots... Plants attacked by wireworms can develop rot and all kinds of fungal diseases. Radish rotting out from the inside.

Burying a wireworm is a good option. onion peel in the garden at.

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

If the plant is attacked en masse, 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 target - radish juice, can nest in the root collar of the fruit, roots or stem. Damaged radishes wither and die.

Marigolds are effective against nematodes:

The whole plant is dried in the open air.
Half a bucket of chopped marigolds are poured with ten liters of water and insisted for three days.
Add 50 grams of laundry soap to the resulting composition, filter the solution.
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... For best results, choose a warm, windless day.

Rapeseed 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. Female rape sawfly lays eggs in the second half of May - early June on the underside of a radish leaf. The hatched caterpillars eat out numerous holes in the tops and lead the plant to death.

In the fight against the pest, an infusion of black henbane will help. You need to take:

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

Of the chemicals, Dendrobacillin, Entobacterin are effective.

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

Cruciferous bug

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

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

Phosbecid, Actellik are used for chemical treatment. The drugs are used according to the instructions.

Summer cabbage fly

The wormy fruits of the radish are the result of the vital activity of the summer cabbage fly... It is difficult to detect harmful insect larvae - they are whitish, up to 8 mm in length. Destroy interior stems, make moves and move towards the fruit.

A folk remedy in the fight against this insect includes:

Salt - 200 grams.
Ten liters of water.

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

Prophylaxis

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

spray wood ash, slaked lime and tobacco dust in equal proportions on the beds with radish;
spray the radish with a decoction of green wormwood;
spray only the seedlings that have appeared with a vinegar solution prepared at the rate of 1 glass 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 part of the pests winters. Closer to frost, the ground in the garden must be dug up so that the larvae and adult insects die.

Adequate crop control, prevention of pests and, if necessary, timely control measures taken will help the gardener to win the fight for a rich radish harvest.

Radish belongs to plants of the Cruciferous (Cabbage) family, therefore, its diseases and pests are the same as for everyone garden crops this group.

By the way, radishes rarely get sick. Most often, the following diseases of fungal or bacterial origin appear on radishes:

bacteriosis - fungal disease leading to the formation of putrid mucus on roots, yellowing and death of leaves;
powdery mildew (white bloom on the stems and the upper side of the leaves) - a fungal disease leading to blackening and death of the leaves;
keela is also a bacterial disease, manifests itself as growths and swellings on the surface of root crops, leads to yellowing and wilting of leaves;
black leg - manifested by yellowing, twisting of leaves and blackening of the stem at the base.

but greatest harm crops are caused by harmful insects. About the most dangerous pests let's talk further.

The cruciferous flea is the main enemy of the radish. These are small black bugs jumping in the garden and damaging plants. They bite holes in the leaves, and when the damage reaches a critical size, the plant stops growing and begins to die. Insects are especially active in hot, dry weather, and their main target is extremely young radishes. Fleas are not as scary to adult plants as to young seedlings.

Belyanka is white butterfly laying its eggs in the soil. It is not she who is dangerous for the radish, but its caterpillars, which eat the leaves, making holes in them.

Medvedka is the most serious enemy of root crops. It is more common in greenhouses because it loves warm soil. The pest eats root crops, forming holes and holes in them.

Cabbage flies - these insects are not averse to feasting on any cruciferous crops... They lay eggs in the ground, from which larvae appear in a matter of days, eating radishes. If you do not start fighting them in time, then the entire crop will be destroyed.

Moth is a gray-brown nocturnal butterfly that feeds on the leaves of cruciferous crops. Like all butterflies, it lays eggs from which caterpillars emerge. These caterpillars very actively devour young leaves, which leads to the complete destruction of plants.

The rape bug is a black beetle with yellow stripes on the back that appears on the radish as soon as it gets warmer. They eat the leaves, forming holes in them, which leads to yellowing and then wilting of the plants.

Wireworms are the larvae of click beetles. They eat any root vegetables, including radishes.

Since radishes love moist soil, slugs can often be found in its garden. During the day, they hide in the ground between the plants, and at night they crawl out to feast on the pulp of root vegetables. Slugs appear in the middle or second half of summer, therefore, they are dangerous only for late varieties.

Ways to fight

The surest way to control pests of garden crops is insecticides, however, for radishes, their use is not always justified and advisable. The fact is that these drugs lead to the accumulation of such harmful substances like nitrates. If the use of insecticides is stopped a month before the harvest, then the nitrates will have time to leave the plant and will not harm the consumer. Radish accumulates nitrates very quickly, and since the growing season of the crop is short (20–40 days), it does not have time to get rid of them. To nitrates in early vegetables did not cause harm to health, radishes are treated with light insecticides, antiseptics or folk remedies.

Diseases of bacterial origin (powdery mildew, rot, bacteriosis) can be fought with Bordeaux liquid. It is a lightweight complex insecticide with high antiseptic properties. Radish does not accumulate nitrates from it, since the solution is used only for spraying the tops and does not get into the soil. The drug is effective not only against fungal diseases, but also against many pests, therefore it is used for almost all cultivated plants as a preventive and therapeutic agent.

To combat keel, an aqueous solution of slaked lime, popularly called lime milk, is recommended. To do this, dilute 2 glasses of the product in 10 liters of water and use it to water the plants. Lime is safe for humans, nitrates are not formed from it in radishes. In addition, slaked lime is used in horticulture as a fertilizer for the soil, so there is no need to worry about the quality of root crops.

A solution is effective from black leg on radishes copper sulfate(1 tablespoon / 10 l of water) with the addition of laundry soap (40 g). Vitriol is an insecticide, but since it is used only for spraying, it does not interact with root crops, and, therefore, nitrates are not formed from it. You can also fight the disease with folk remedies - a decoction of onion husks (20 g / 1 liter), you need to insist it for a day and process the tops of plants.

It should be remembered that nitrates are formed from a large amount of organic matter in root crops, so the amount of fertilization should be minimal.

You can get rid of cruciferous fleas and other insects using exclusively natural remedies, from which nitrates are not formed in radishes: ash, tobacco dust, laundry soap, wormwood.

Video "Wood ash against pests"

Experienced gardeners use wood ash as natural fertilizer, however, it is no less successfully used against pests and diseases. Details in the video.

Processing technology

Whatever method of treatment is used: spraying, watering or spraying a dry mixture, it will be effective only if the agent lingers for some time in the soil or on the radish itself. The first surface watering or rain will immediately wash away the product and will not give the desired result. Therefore, if the radish was sprayed with a medicinal solution or sprinkled with a mixture, then it must be transferred to drip irrigation (directly under the roots).

If radishes grow in the vicinity of cruciferous weeds, then they should be watered abundantly with insecticides - otherwise they will become a breeding ground for insects.

It is better to process radishes in dry and calm weather. Usually such works are carried out in the evening. However, to eliminate fleas on radishes, you should choose the daytime, since insects are especially active in the heat. A flea can be fought not only with the help of solutions and mixtures, but also by mechanical means: by covering the garden bed, as well as by hanging sticky tapes to which insects stick. These harmless measures help to wait until the radish grows up and the fleas are less dangerous for it.

How to prevent pests

The most reliable way to prevent diseases and pests on radishes is to disinfect seeds and soil when sowing a crop. Compliance with crop rotation also effectively solves this problem.

It is important not only to change the location of the garden bed every year, but also to avoid re-seeding during the season.

Radish is a precocious vegetable, and many gardeners try to grow several crops per season in the same garden. This is the reason for outbreaks of fungal diseases, which with each subsequent sowing become more active.

Good precursors for radishes are: potatoes, cucumbers, tomatoes, legumes, garlic, onion. Since early radish ripens quite quickly, it can be sown in an area intended for planting seedlings of peppers, tomatoes, eggplants - this is an example rational use landing area.

In addition, many pests such as the cruciferous flea do not like the smell of nightshade crops. She also does not like moisture, and if the radishes are watered abundantly, then it is quite possible that insects will leave the garden.

An important role in the cultivation of crops is played by proper care... Remove weeds from the garden in time, since it is from them that the pests move to the beds with cultivated plants... Some gardeners plant plants and flowers next to radishes, which emit a special smell that repels pests. Such plants are: tansy, calendula, celandine, marigolds, coriander, dill.

When planning to plant a radish, choose early varieties as well as resistant to diseases and pests. Early sowing is the most the right way prevention of many diseases and obtaining a high-quality, undamaged crop.

Gardeners value radishes for their tasty and healthy roots, which are eagerly awaited. However, in some cases, the yield can be significant and for a short time spoil the pests called cruciferous flea beetles. These little bugs bring a lot of trouble. How to save seedlings and get rid of insects, we will talk in this article.

What is this pest?

The cruciferous flea is mainly harmful to 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 beetle prefers to settle on weeds such as wild radish, shepherd's purse; from garden crops, it especially loves turnips and cabbage. However, radish remains a favorite delicacy in the early stages of the pest.

The insect is very small in size, the length of its oblong oval body is up to 3 millimeters. At the same time, the flea can fly. There are several varieties of pest, among them black, blue, light-legged and others. The differences are mainly determined 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 peculiar pits. The flea is especially dangerous for young greenery, since it can gnaw through delicate leaves. Thin roots of crops serve as a delicacy for the larvae. The most active pests are during the day, excluding the interval from 13 to 16 hours, when the sun is especially scorching.

V winter period an adult flea hides in the remains of plants, the crevices of greenhouses, and the soil. When spring comes and the ground thaws, insects come out and start actively looking for 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 emerge on the surface. An insect can give birth to a whole summer period up to 3 generations.

Prevention measures

Any problem is easier to prevent than to deal with its consequences later. Therefore, specialists and experienced gardeners recommend several preventive measures that will help preserve radishes. Let's 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, since the insect 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.

Control methods

In order to get rid of a cruciferous flea, you need to make sure that this particular insect is harming the crop. This is not so difficult to do, because despite the small size of the pest, it can be easily detected visually. Bugs jump over leaves with gnawed holes.

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

You should start with prevention and deterrence, chemicals 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 borne in mind that in this case it is not enough to process the crops once or twice, systematic care will be required, which, accordingly, involves a lot of time. There are several of the most common folk methods, the excellent action of which has been confirmed by a huge number of examples:

humid environment;
dry pollination;
shelter non-woven fabric;
setting traps;
spraying with infusions.

Let's consider the listed methods in more detail.

Wet environment

The red-colored flea feels great in hot and dry weather, but it does not like moisture. Therefore, when planting, it is recommended to choose the most humid part of the garden. Watering abundantly will also scare away the pest. At the same time, do not forget that he is afraid of strong odors, so it will be useful to add pungent-smelling agents to the water.

Dry pollination

Planting can be pollinated by various means, since the beetle chooses the cleanest leaves for eating. This method is very popular among gardeners, as it does not require large financial costs and is very effective. Mixtures can be different, most often ash is used in combination with tobacco or road dust, as well as fluff 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 lay 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, and then gently shaken over the sprouts. This method is also called dusting.

Minus this method is that it does not work for a single use. Good protection can be provided only when dusting is carried out systematically.

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

Nonwoven Shelter

If the crops are covered with a canvas, they will be protected not only from insects, but also from weeds and cold weather... The material must be chosen correctly, it must transmit light, water and air, but at the same time it must be an insurmountable obstacle for pests. For example, lutrasil or spunbond works well.

In addition, many recommend dusting the radish before the shelter, which will serve additional protection... When found under such a canvas, the radish will grow, get stronger, the leaves will coarsen a little, therefore, 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 any special skills.

To make a flag, a piece of fabric is attached to a stick and treated with some kind of adhesive. Solid oil is excellent for this purpose. After that, you need to walk along the radish beds, slightly touching the flag of 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 short time intervals. Such flea fishing will help to significantly reduce the number of insects in the beds.

Another trap is made using waste engine oil in which a piece of cloth is moistened. Along the beds with radishes, boards are laid out, on which the impregnated fabric is laid. So that as possible more insects trapped, the material must 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 for dusting, are suitable. There are many popular recipes, each selects the simplest and most effective in a particular case. Here are the most common ones.

A glass of ash is poured into one liter of boiling water, mixed and left for 48 hours. After that, you should rub laundry soap and add it to the infusion. You can also use liquid soap... Radish is 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 cheesecloth.

Chop the garlic. Tomato stepchildren 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.

Gardeners know well how difficult it is to achieve big harvest in the beds, if not pest control. Even the smallest insects can cause tremendous damage to vegetable crops.

This insect got its name from taste preferences- she really loves cruciferous plants. V field conditions the flea feasts on weeds (rape, yarotka, shepherd's bag), and in the gardens it eats turnips, turnips, radishes.

Gardeners without experience sometimes do not even pay attention to a small insect jumping like a flea (hence it got its name). It would seem that such a trifle cannot cause much trouble. But if measures are not taken in time, the flea can destroy plants in the beds in a matter of days.

These bugs are hardly noticeable due to their size (no more than 3 mm) and often merge with the ground. The color of cruciferous fleas is black, but some species of insect have yellow stripes on their backs.

As for the radish, the planting of this culture falls just on the active period in the life of the flea. It is in May that insect larvae crawl through the beds in search of food. AND young radish will be a real find for them.

Having then transformed into an imago, the insect eats the tops. The flea eats the delicate leaves of radish to the holes, as a result of which they dry out. In the same place, on the leaves, beetles lay yellowish eggs.

Usually, the cruciferous flea is fought with the help of purchased chemicals (Actellik, Bankol, Karate, etc.). But since radish belongs to an early ripening culture, chemical substances not worth using(so that the vegetable is not saturated with them). But a great solution problems can become folk remedies.

Folk tricks

How to get rid of cruciferous fleas on radishes without using chemicals? Here are our tips:

The fight against the flea should be started almost immediately, as the radish is sown in the garden... The soil is sprinkled with a "pillow" of wood ash and tobacco dust. This will not only protect the radishes but also fertilize the soil.
When the tops hatch out, you can also sprinkle it with ash and dust (even a regular street one will do). This preventive measure should be applied at least once a week... And as an option - ground black pepper or slaked lime.
Spraying gives a good result... But they are used already when the flea was found on the culture. You can dilute a bottle of vinegar (or 2 tablespoons of essence) in a bucket of water, or prepare a decoction from tomato tops collected as a result of pinching the bushes. Laundry soap is also rubbed here (0.5 pieces).
Craftsmen came up with original traps various configurations. The simplest of them is a canopy over the garden. The underside of the awning is lubricated with any sticky compound (for example, tar). In a few days it will be possible to harvest insects.

Preventive remedies

To make it easier to deal with the cruciferous fly, you can pre-protect the beds from its invasion:
radishes should be planted next to tomatoes - the smell of nightshades repels insects;
for the same reason, tansy or celandine can be planted around the perimeter of the garden;
you can also make a distracting maneuver by planting a favorite flea weed next to the radish;
to postpone the planting of crops to an earlier time (immediately after the snow melts);
choose moist places for sowing radishes.

For those who do not want to "bother" clarifying the relationship with pests, you can use the method of growing crops in greenhouses. But the ubiquitous insect is able to reach there too.
