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 of various diseases can 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 flea radishes, are there folk remedies against this insect?

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

1. Ash.
2. Tobacco dust.
3. 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:

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. Carry out processing in the morning or evening in calm, dry weather.
4. The duration of action of the drug is 15-20 days, pests die by 90% on the third day after spraying.

Belyanka

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:

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 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.

4. After the allotted time, strain the product.
5. Dilute one part concentrate to ten parts water.
6. 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:

1. The whole plant is dried in the open air.
2. Half a bucket of chopped marigolds are poured with ten liters of water and insisted for three days.
3. Add 50 grams of laundry soap to the resulting composition, filter the solution.
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... 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.

Almost everywhere.

Pollination with wood ash or tobacco dust is recommended against these pests. Seeded in early dates radish prevents damage to plants. Hot, dry weather contributes to the emergence of diseases and pests.

1. Before planting, the seeds can be held in a damp cloth to hatch. To protect against dry rot planting material warmed up for 15 ... 20 minutes in heated water (about 45 ° C). This procedure also contributes to more early appearance seedlings.
2. Early maturing varieties (growing season 25 ... 30 days). Here one can distinguish such varieties as "Zarya", "Ruby", "Rose-red with a white tip", "Camelot", "Cherry-bell", "Early red" and others.
3. Radish is an early vegetable crop that is one of the first to harvest. 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 that can destroy the crop in a matter of days or seriously spoil it, making it unfit for human consumption.
4. It is quite simple to deal with them (and, of course, without using pesticides that will not decompose before harvesting and which you will "treat" your family to).

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

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

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

The benefits of radish. Radishes have a huge variety 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 the growth of cancer cells. Guys are fiber - doctor Aibolit for our body.

Preparing radish seeds for sowing

To prepare the working solution, add about 2 glasses 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 scatter 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 is allowed much earlier). Agricultural technology for growing radishes involves sowing seeds in lines, deepening them by 1 ... 2 cm. Sowing deeper is not recommended, since there is a risk that the root crop will not tie up. The optimal distance between rows is considered to be 8 ... 10 cm. For planting beds of 10 square meters. m will require about 15 g of radish seeds. There are about 1000 seeds in 10 g.

Optimal seeding time

Mid-season varieties (growing season 30 ... 40 days). Sorts "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 amount of the crop. Fleas have absolutely small size body with pronounced metallic luster... As a rule, insects are of the same color. The spring cabbage fly, despite its name, also spoils the radish. Females lay eggs in the soil, from which larvae 6-8 mm long, gray or white, emerge. The larvae move closer to the root crops and begin to actively eat them. Over time, they spread to the stems. If you do not take action, the crop will be spoiled. The rape bug eats absolutely any cruciferous plants, including radishes. Since bedbugs hibernate under foliage, they become active immediately after warming. Females lay clutches directly on the foliage. Damaged plants turn yellow and wither. The key is to clean the garden thoroughly in the fall. The fewer last year's leaves, the lower the likelihood that pests will appear in large quantities... Unfortunately, this is not always enough. The nocturnal cabbage moth eats cabbage, radishes, turnips, and also gladly absorbs plantings of turnip, watercress, horseradish and radish. The moth looks like a small butterfly, its wings are brown with stripes. Caterpillars of the cabbage moth eat leaves in large quantities. Slugs live on cruciferous plants, especially young ones. Pests spoil mainly radish foliage. Slugs live for a long time, and they reproduce well enough, 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. Nutcrackers or wireworms eat all root vegetables, including radishes. Since their presence is often ignored by summer residents, significant damage is noted upon harvesting. 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 through a small fire from stick branches, is sprinkled in the early morning (over dew so that it sticks to the leaves) the crops of radish and the flea beetle retires in a hurry.

It also gnaws young shoots of radishes and root crops.

To postpone the planting of crops to an earlier time (immediately after the snow melts);

Radish pests and control

Spraying gives a good result

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.

A few days after germination, the radishes are thinned out. Density of crops is one of the reasons for radish shooting. Do not regret - pull it!

Radish 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 pest control will wash away the protective compound.

To get friendly and strong shoots, 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 suggest that it is better to plant one seed at a time, since thinning can damage the root of the plant left behind, after which it develops worse and can go to the arrow, which will significantly affect the harvest.

Late-ripening varieties (growing season more than 40 days). This group includes the varieties "Dungansky", "Zenith", Rampous ".

Harvesting and storage

With cabbage flea can be fought with ash. Sprinkle some ash on the leaves and the ground. Carry out the processing several times a week until the pests disappear completely. Complex preparations are presented in a wide range of gardening stores. They usually come in the form of tablets or ampoules, which must be diluted in water. The method of application is detailed on the package - you cannot make the solution more concentrated, otherwise the radish may die. Do not forget to periodically paint greenhouses, elements of which are made of wood. Otherwise, not only pests may appear, but also the development of many diseases in radishes.

Small cruciferous fleas gnaw at the leaves of radishes and all cruciferous plants, especially in dry weather. The most effective method the fight against them is the shelter of plants, especially young ones, a covering material, I use lutrasil. Less effective is the use of a soap solution with ash, pepper. You can plant cilantro and garlic next to radish crops, but the most effective is the use of a covering material.

Radish belongs to an early ripening culture, chemical substances not worth using

With early sowing, the radish has time to get stronger before the mass appearance of the cruciferous flea, so deterrent measures (pepper, mustard, ash) can be dispensed with.

Radish care

The second planting is carried out after the appearance of the first true leaf in the plants of the first planting - from April 25th. Avid fans can plant radishes a couple more times in May and in the first half of August. Usually this is not done, since radishes are replaced by cucumbers, turnips, radishes, various varieties of cabbage.

If you remove the tops and roots of a freshly harvested radish, then it can be stored for only 5 ... 6 hours, as it will quickly wither.

Care during the growth of radishes is traditional: weeding, watering, periodic loosening. In dry weather, watering is best done twice a day, in the evening and in the morning, this contributes to the production of juicy and dense root crops. With a lack of moisture, the fruits are rough, bitter, with voids inside. Radish especially needs watering after the appearance of a real leaf, when the root crop is being formed. But it is also not worth getting carried away with watering, because excess moisture leads to cracking of the fruit.

Radish pests

Radish bears fruit well on loose light soils with an abundance of moisture. When grown in clay and dense soils, root crops are hard and shallow, often have a gnarled shape.

Radish varieties: 1 - "French", 2 - "Vera" (round form of radish), 3 - "white radish".

There are pests called cruciferous fleas. They are very fond of eating radish leaves. They gnaw through small holes. You can fight these pests with chemistry. Suitable for this are fufanon, kemifos.

Harvesting

Radish pests cause irreparable damage to crops

Common signs of pest damage to radish

The main pests of radish and the fight against them

There are ground and underground pests that can spoil the radish crop. If you notice the first signs of damage, you need to urgently take action. There are many effective ways pest control to help deal with the problem early.

Cruciferous fleas (Latin Phyllotretacruciferae)

If radish pests are found on the surface of the foliage, which jump high and destroy the tops, gnawing holes in it, then cruciferous fleas are on your plants. Such damage is fraught with infection of the leaves with bacteriosis, which can spread to root crops. In addition, the complete wilting of the green mass will cause growth arrest, or deformation of the radish.

To further protect the plants, they are sprinkled once a week with a mixture of ash and lime in a 1: 1 ratio. This should be done in dry weather, and be sure to repeat after rains.

In case of mass defeat, the following drugs are used to fight: Tod, Alfatsin, Zolon, Kaiser, Arrivo.

Cabbage whites (Pierisbrassicae)

They love the juicy leaves of the radish. Caterpillars are located on the underside of the leaves and gradually spread to neighboring plants. The first sign of the appearance of an insect is twisted leaves with oblong holes.

When spreading pests, chemical agents are effective: Iskra M, Kemifos, Fitoferm.

Garden moth larvae (Latin Noctuidae)

Before treating the radishes with chemicals, you can try spraying with an infusion of potato tops, which is good for the garden scoop. To prepare it, take 500 grams of dried plants and leave in a warm place for 4 hours. Before spraying, 50 grams of grated laundry soap can be added to the solution. Irrigation is carried out in the evening, always in dry weather.

If folk remedies do not help, it makes sense to apply chemicals... In the fight against these insects, Zeta-cypermethrin, IntaVir are effective.

Wireworms and clickers (lat.Elateridae)

They give preference to young shoots. The click beetles themselves feed on leaves, and their larvae feed on juicy roots. Wireworm damage is fraught with the development of rot, and many other fungal diseases. Radish begins to blacken and rot from the inside. The damaged crop cannot be stored, most often it loses its taste.

Nutcrackers cannot tolerate ammonium sulfate fertilizers. The use of such funds will help get rid of pests, and therefore from contamination of the soil with their larvae.

A good prevention against wireworms is to add onion husks to each well when planting radishes and other cruciferous crops. If the pest has attacked a large area of ​​the site, you can use the drug Bazudin.

Cabbage moth (Latin Plutellaxylostella) and cabbage fly (Latin Anthomyiidae)

The insects themselves are safe for radishes, but the larvae of these insects damage the root of the plant, eating holes in it. Caterpillars can completely destroy young leaves, which will stop the process of photosynthesis and, accordingly, the development of the root crop.

The question arises of how to spray radishes from pests before they have time to lay the larvae. Cabbage flies and moths will die if you use substances based on naphthalene, slaked lime, camphor. If more than 15% of plants are damaged, it is worth applying Lepidocide, Bitoxibacillin.

Stem nematodes (lat.Ditylenchusdipsaci)

The most dangerous pests radish - stem nematodes. They feed on the sap of the plant, they can live in the root collar of the fruit, the very root, or the stem. Damaged radish stops growing, in many cases the plant withers, becomes sick, and dies.

If the risk of infection is too high, that is: nematodes were found in neighboring plants, or these pests were in the beds last year, insecticides should be applied. In the fight against nematodes, they are used: Dimethoat, Rogor, Vidat.
