Parasites hibernate in the soil at a depth of a few centimeters. They rise outside in the spring when heat is stabilized and the soil warms up well. It is during this period that seedlings are planted in open ground.
Gnawing pests gnaw passages in young stems, eat leaves. You can identify them by the yellowness of plants, their growth retardation and through holes in shoots.
Fighting cabbage pests with folk remedies involves deep digging of the plot in early autumn, the destruction of all plant cabbage residues and weed grass. At the advanced stage of the defeat by the beetles, they need to be treated with insecticides.
Whiteflies are one of the most common cabbage pests that infects almost all varieties of garden crops. In appearance, an insect measuring 2-2.5 mm looks like a moth. The whitefly may have a white or yellowish body.
Females lay eggs on the inside of the leaf. In the process of growth and development, insects secrete a sweet sticky substance, which attracts sooty mushroom.It can provoke the development of many diseases, mainly fungal, so often the leaves of infected plants are covered with black spots.
It is very difficult to deal with pests of this type of cabbage on our own. First, insects are lured with tobacco. Then, special baits for whiteflies are installed on plants and near them.
An effective method of control is spraying leaves with water, then loosening the soil and fertilizing it with humus.
The fly does tremendous damage to cabbage plantings. Pupa of a fly measuring 8 mm winter in the ground. With the onset of spring, females begin to intensively lay eggs in the ground next to the stems and roots of seedlings.
The larvae that appear after a week begin to gnaw the roots of young seedlings, then root insects gnaw through the passages in the stems of plants.
Fight with pests of cabbage is carried out by spraying the aerial parts of plants with a solution of burdock. To protect cabbage from pests, the following infusion should be prepared: pour 2 liters of finely chopped burdock leaves with a bucket of warm water, insist for 48 hours. Filter the plantings with filtered solution.
If necessary, the treatment is repeated after 10 days.
Spraying is carried out after removal from the site of plant residues of weed grass and other garden crops. After harvesting, the soil is dug up.
To reduce the harmfulness of such a pest, young plants are spudded after planting in open ground. Thus, they have additional roots due to which plants can still be saved.
A distinctive feature of this pest is the presence of lemon strips on each wing. A beetle with a black carapace and black paws about 3-4 mm in size is called a wavy flea. In appearance, this insect looks like a black flea. The only difference is dwelling in wetter conditions and the color of the insect.
With the onset of warm spring days, the female parasite rises from the soil to the surface and makes the laying of testicles. After 10 days, the appeared larvae begin to intensively eat the roots, leaves and stems of plants.
After 3 weeks, the larvae turn into pupae, and after 2 weeks a new offspring of insects appears.
The fight against these parasites is carried out using tansy infusion. It is prepared as follows: 700 g of dry grass or 1.8 kg of fresh foliage is poured with a bucket of warm water. Then this mixture is boiled for 40 minutes, insisted under a lid for 3 hours, filtered.
Treatment regimen: spraying seedlings is carried out in the evening every 2 days. The number of treatments per week – no more than 3.
2 weeks before heading out, folk remedies are not used for spraying plants.
This microscopic worm-like insect harms young plantings of the Cruciferous family. The length of its body is 1-1.5 mm.
Most often, this pest is affected by seedlings grown in greenhouse and greenhouse conditions.
A microscopic worm penetrates the root system of plants and eats it from the inside. Defecating, this pest releases a poisonous substance, which on the surface of plants is converted into growths or galls. Inside these blisters, larvae develop, which are also no less dangerous for young seedlings. Plants affected by this cabbage pest lag behind in growth, as a result of which the yield indicators and taste qualities of vegetables are reduced.
Processing cabbage against underground pests involves the complete replacement of old soil with new soil to a depth of half a meter. In addition, a deeper layer of soil is watered with an insecticidal solution.
This bloodworm can be found in almost all regions of our country. Butterflies with white or lemon wings with black patches on the surface lay eggs on the underside of seedling leaves.After 7-10 days, caterpillars hatch from them. Belyanka eats all seedlings, and in a short time it is able to destroy all plantings.
When the plantings are severely damaged, the plants stop growing, they don’t tie out the head, and its cap is damaged. Often such plants die.
You can save cabbage from pests of this species in two ways:
- Plant a bed of carrots, dill or onions near the plants. These garden crops, highlighting a specific smell, repel insects.

- plant cabbage early, before the beginning of summer moths;
- catch butterflies with their hands or a net, luring at night with a lamp, animals also help in this;
- completely remove the remains of weeds and cabbage from the area.
Such plant protection will help preserve young plantations and get a good harvest.
A scoop is a butterfly pest with a wingspan of up to 5 cm. The upper wings are brown in color with light spots, the lower ones are light brown in color.

With the onset of heat, the females crawl out, climb the stems of plants and lay eggs on the surface of the leaves. Females gnaw stems, making moves in them. Over time, they sink to the roots and destroy them. On the root surface, one can see bloats (galls) in which a new generation of gnawing parasites develops.
There is no point in fighting these cabbage pests.In this case, careful digging of the soil in the fall, removal of fallen leaves, and plant debris from the site is required.
