Pests of radish (radish) and the fight against them with a photo

Every gardener who grows crops on the plot met with radish pests. In nature, there are enough who want to feast on the juicy root crops of insects.

Often the gardener does not pay attention to the condition of the plants. The tops are damaged - you think, there will be enough for everyone. Some adhere to the rule: plant as much as is enough for themselves, friends and enemies.

Sometimes there are too many of the latter. By the time of ripening, there is nothing to clean: the radish is small, corroded, tough. Who is guilty? Pests!

But an experienced gardener does not miss a single detail. He regularly inspects the landings. If necessary, immediately begins to act. And the harvest pleases: the roots are even, juicy. And there are many of them: there is something to share with friends.

Common signs of radish damage by pests

The gardener should inspect plantings throughout the entire period of root ripening. It is recommended to be alert when:

damage to growing point on young plants;
perforated leaves;
oppression of seedlings;
delayed development and growth of tops;
damage to the protruding part of the roots.

Even in isolated cases, it is necessary to identify the pest and work to protect the crop.

The main pests of radish and how to deal with them

The radish belongs to the cruciferous family. She has common pests with cabbage, turnips, rutabaga. When related crops are affected, attention should be paid to the condition of the crop plantings.

Cruciferous flea

Very dangerous pest. Able to destroy seedlings before the growth of true leaves.

This is a jumping bug. It overwinters as an adult under unharvested plant debris. When warm weather arrives, it activates. Before sowing cultivated plants, it lives on wild representatives of the Cruciferous family. After germination of radishes, turnips, radishes, it feeds on young leaves.

Gnaws through holes in tender plants. On more rigid makes indentations. Activity period: from morning to 13:00 and from 16:00 to 18:00. Hot weather favors breeding.

The flea lays its eggs in the ground. The larvae live on young roots. They also feed on them. Landings are disappearing.

Recommended for prevention:

remove plant debris;
dig the ground deep in autumn;
apply mineral fertilizers to the soil;
observe crop rotation;
fight weeds;
apply compact planting of protective plants.

Gardeners dust the ridges with ash and tobacco dust. In difficult cases, insecticides are recommended.

Caterpillars of the white butterfly

This insect is familiar to every adult. They are touched by children and townspeople. The butterfly itself is not harmful to the radish: it feeds on the nectar of flowers (alfalfa, dandelion, clover).

But she lays her eggs on the leaves. Voracious caterpillars that feed on leaves develop from them. In advanced cases, they completely destroy the tops of the radish. The root crop stops developing.

The gardener should regularly inspect the plantings. Pay attention to the back side of the leaves. Destroy immediately discovered clutches of eggs and caterpillars.

Mechanical methods of protection are recommended to be combined with the treatment of plantings with insecticides (according to instructions).

There are folk methods of protecting plants from whites. Along the perimeter of the ridge, sticks with halves of eggshells are stuck. The butterfly does not like competition and flies to lay eggs elsewhere.

Some gardeners thickly sprinkle plantings with sifted oven ash. Belyaka - clean. It will not grow on dirty leaves. After rain and wind, protection is updated.

Spring cabbage fly

Belongs to the type of flower fly. The mass summer starts from the moment of flowering of bird cherry and cherry, ends after the flowering of lilac.

The fly itself feeds on nectar. She pollinates plants. But its larvae are harmful to gardeners. The fly lays its eggs in the soil under radish plantings. The hatched larvae gnaw through tender root crops, build passages. Outwardly, the radish looks oppressed, the tops begin to wither.

At the first sign of damage to plantings by a flower fly, it is necessary to start a fight. Damaged roots should be dug up and burned. Treat the soil with an insecticide.

Prevention gives excellent results. Weeds must be removed from the site. Protective measures:

It is recommended to plant plants with a pungent aroma along the perimeter: marigolds, celery. They will scare away the fly.
Beds should be mulched with coarse wood chips or covered with dark non-woven material: there is nowhere for the fly to lay its eggs.
To stretch a net with small cells completely over the landings: the fly will not overcome the obstacle.

Some gardeners thickly sprinkle the ridges with oven ash: this prevents the pest from laying eggs.

Cruciferous bug

Cabbage bug hibernates under plant debris. When heat comes, it flies out and lives on the weeds of cruciferous plants. After the advent of cultural moves to them.

The female lays her eggs on the reverse side of the leaf. The larvae feed on the juice of the leaves. Small dots are visible through the light, they turn into spots. The leaf dies, the plant weakens.

Insecticides are used to control the pest. Prevention gives excellent results: destruction of weeds, digging the soil before winter.

Some gardeners attract enemies of the cabbage bug to the plot: the motley fly phasia and the egg-eater trissolkus. They naturally reduce the pest population.

Cabbage moth

This butterfly is inconspicuous beige. She feeds on nectar. But her caterpillars are capable of destroying the radish crop.

As soon as the pest begins to flutter over the ridges, the fight should begin. It is recommended to inspect the back of the leaves and the middle of the rosette. Caterpillars must be collected and destroyed, eggs must be washed off with a solution of green soap. In case of severe lesions, radish plantings should be treated with insecticides.

Some gardeners reduce the pest population with traps. A long-drying substance (pine resin, glue, grease) is applied to a piece of yellow cardboard or plastic. Butterflies stick to the composition. Traps with insects are destroyed and replaced with new ones.This method helps to identify other winged radish pests as well

Cabbage moth

This is a nocturnal pest. The butterfly is painted in a dirty gray color. She lays eggs on the underside of the egg. Young caterpillars make holes in the leaves of the radish, grown stronger - gnaw through the bot. Then the caterpillars go underground for the winter.

Preventive measures will help get rid of the pest. Digging deep, removing weeds, crop rotation and neighborhood rules.

Some gardeners lay out pieces of synthetic material soaked in kerosene or tar among plantings to scare away butterflies. Caution should be exercised when using insecticides on early varieties of radishes.

Rape Sawfly

The insect's ovipositor looks like a jagged saw. With it, the female pierces the leaves on the underside and lays eggs. The caterpillars hatch. They eat the leaves. After them, veins remain from the leaves.

Most active in warm, dry weather. Precipitation and cold weather are detrimental to them. Caterpillars wait for short rains on the underside of the leaves.

Agronomists recommend creating plots with bait plants from the Cruciferous family. Pests get over it. The grass is cut and burned.

The wasp rider is a natural enemy of the sawfly. She lays eggs in the body of caterpillars. Beneficial insects should be attracted to the site.

In rainy weather, caterpillars must be collected and destroyed. With large pest populations, it is recommended to use insecticides.

Rape beetle

Glitter blue-green bug. Winters in the ground. When the soil warms up to 10 degrees Celsius, it comes to the surface.

Active from May to the end of June. Eats the buds from the inside. Prefers canola, but damages any cruciferous plants (and radishes too). Able to destroy 70% of the crop. At the first sign of planting, it is recommended to treat with an insecticide.

Slugs

Damage the tops and parts of root crops protruding above the soil surface. They feed at night. During the day they hide under boards, plant debris.

To protect plantings, it is recommended to collect and destroy pests during the day. A thick layer of crushed eggshells or lime should be poured around the perimeter. This prevents the clams from crawling up to the plants.

Aphid

Parasites on tender, young radish leaves. Sucks juices and weakens plants.

Insect is passive. Garden ants carry it to radish plantings. Aphids secrete a sweet juice that ants like.

For pest control, it is recommended to destroy anthills. A good result is obtained by treatment with the drug “Muracid”.

Aphids should be washed off the leaves with a solution of green soap. To attract ladybugs, marigolds, calendula, and chamomile are planted next to radish ridges. Spraying with infusions of tobacco or orange peels will help scare away aphids.
