Radish pests

The main pests of radishes are:

The black beetle got its name for its external resemblance to a flea and jumping ability, as well as for its gastronomic preferences: love for cruciferous crops. The pest gnaws through the young tender leaves of the radish and makes depressions in the harder ones. The highest activity of the flea is from 10:00 to 13:00 and from 16:00 to 18:00. The heat promotes its reproduction. The insect lays eggs in the soil. The larvae settle on the roots and eat them. Thus, the landings perish;
2. White butterfly. It is dangerous because it lays eggs on radish greens. From them larvae-caterpillars develop, which feed on leaves. The presence of caterpillars can be recognized by twisted foliage with elongated holes;
3. Spring cabbage fly. The insect has a small gray body with transparent wings. Attacks crucifers during the flowering period of bird cherry. The period of activity ends after the lilac fades. Pest larvae gnaw through passages in roots and stems;
4. Cruciferous bug. The pest hibernates under the remains of plants. With the onset of warmth, it lives on wild cruciferous plants. Switches to cultural when they appear in the garden. The female insect lays eggs on the back of the leaves. After about 14 days, larvae form, after a month they turn into mature insects. Both mature bugs and larvae harm the plant. These pests suck the juice out of the leaves. They are especially active if the land is devoid of moisture. It is difficult not to notice this parasite on the plant, its red-black color contrasts with green leaves;
5. Cabbage moth. This small pest is gray-brown in color, with a dark fringe on the wings, lays eggs on the lower surface of the leaves. On days 3-7, caterpillars appear from them, they feed on sap and leaf tissues;
6. Garden moth larvae. They eat young shoots of radishes. This stops the growth of the root crop. If you do not destroy the pest in time, then the greens can grow, and the root crop will remain a root, will not develop;
7. Clickers and wireworms. Adult clicking insects eat leaves of young plants. Their larvae (wireworms) are those who eat radishes in the ground. If the radish is damaged by wireworms, rot and other fungal diseases develop. The fruits turn black and rot from the inside.
