The main pests of radish
The best is obtained early type radishes.Seeds are planted in the soil until the moment when the spores of fungi and larvae become active, therefore the fruits form and ripen without much difficulty. It is more difficult for middle and late ripening vegetables, the vegetative period of which coincides with the intensive reproduction of harmful microorganisms and insects. They literally attack young shoots, wanting to drink all its juices.
If there are signs of damage to plants, it is impossible to hesitate; parasites in just a few days can destroy almost the entire crop. Serious problems can be avoided if timely preventive maintenance is done.
Processing plants against flea crucifers
Insect is the main enemy of radish. Small black bugs jump over the bed very intensively, so they are easily detected. Pests gnaw leaf fragments, quickly increasing the area of damage. The damaged plant stops growing and dries out. Of particular danger are parasites for young shoots. Their activation and increase in the population is observed in dry hot weather.
The likelihood of attack of fleas is reduced if you timely inject feed to the bed of 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 procedures once in 5-7 days.
What to spray against whitefish
The white butterfly poses a danger to the radish by laying its eggs directly on the soil. Emerging caterpillars easily move to the leaves and eat them.
To protect the radish from the whitefish, it is necessary to spray a solution of mustard (2 tbsp.), Ground black pepper (1 tsp.) And salt (2 tbsp.) For a bucket of water.
Fighting cruciferous bug
Black little bugs with bright orange stripes suck the juice out of the radish, causing the young shoot to dry out.
Protect the bed from the pest can be if you spray it with infusion of dope ordinary or henbane. Preparation of the working solution involves the infusion of 500 grams of leaves in a bucket of water for 12 hours.To make the composition stay longer on the leaves, it is recommended to add 2-3 tablespoons of chopped household soap.

How to protect seedlings from rape sawflies
In the second half of May - early June, the female of the rape sawfly lays eggs. When choosing a place, preference is given to radish, located on the underside of the sheet. After only 6-10 days, very voracious caterpillars emerge 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, it is necessary 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 at least 12 hours, after which the liquid is filtered through a sieve. The resulting infusion is diluted with 8 liters of water, add grated soap and treat the beds.
How to process radish against babanuhi
A leaf beetle with a wonderful appetite can destroy a garden in a matter of days. You can recognize it on an even color with a greenish tint and brown paws. As soon as the parasites leave the wintering grounds at the beginning of June, they begin to feed on the lush green of the young shoots.Right in the gnawed leaf pits, females lay eggs.
Prevention of insects can be prevented by preventive measures, which include autumn site cleaning and soil digging.

Rapeseed flower eater
A small bug (body length not more than 2.5 mm) of black color with blue tint, perfectly tolerates frosts in plant debris. In the spring is activated, laying eggs in unblown buds.
If a parasite is detected, it is recommended to immediately treat it using one of the following means:
- etafos (0.2%);
- anometrine (0.04%);
- Thiodan (0.2%);
- zolone (0.3%);
- cymbush (0.03%).
Cabbage fly and cabbage mole
Both parasites attack almost all cruciferous plants. Insects are terrible not only because they lay off the larvae, which later feed on the sap of the plant, but also the ability to tolerate various diseases.
Among the important measures for the protection of radishes from pests:
- crop rotation;
- thorough autumn cleaning;
- the introduction of fertilizers into the soil;
- selection of quality seeds for planting;
- introduction of dressings to strengthen the immunity of plants;
- spraying karbofos;
- treatment of beds with biological products (Dendrobatsillin, Lepidotsid, etc.).

Preventive treatment of radish from pests
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 mixture of naphthalene and road dust (1: 1);
- spraying on the beds of powder from wood ash, slaked lime and tobacco dust (all components are taken in equal proportions);
- morning sprays with a solution of wood ash (for 3 liters of water, a liter can of ash and 2-3 tablespoons of crushed laundry soap);
- spraying the seedlings with vinegar solution (1 cup of 9% vinegar in a bucket of water);
- spraying of plants with a decoction of green wormwood.
It is clear that one treatment can not do, therefore, experienced gardeners practice weekly procedures that are repeated for 1.5 months.
Scare off the invasion of pests can properly selected crops planted next to the radish. These are: potatoes, cumin, dill, tomatoes.Fragrant tops of these plants discourage any desire from the parasites to colonize and postpone the larvae.
After each season, thorough cleaning of plant residues should be carried out. It is in them that most of the pests overwinter. Closer to the frosts, the bed should be dug up so that the larvae and adults would freeze.
The spring diet is supplemented with fresh salads, the main ingredient of which is often radish. Proper care, prevention and control will not leave the parasites a chance to destroy the crop of bright root vegetables.
