The cabbage scoop is a polyphagous pest that can destroy a significant part of cabbage plantings because it prefers to attack all cruciferous crops. Belongs to the class of insects, the scoop family. To protect cabbage beds, you need to know the peculiarities of the development of the pest and methods of dealing with it.

Why is the cabbage scoop caterpillar dangerous?

To begin with, you should briefly familiarize yourself with the pest itself - the cabbage scoop. This is the name of the butterfly, although its larvae pose a danger in the garden. She is rather nondescript, she has large wings with denticles along the edges. The color of the scoop is grayish-brown, fertility is very high.

The nondescript appearance of a butterfly should not make summer residents feel safe for cabbage.

While the cabbage is growing in the garden, the pest can produce 2 or 3 offspring. But the number of eggs in a clutch directly depends on the region. In areas with a cold climate, this happens only once. The southern regions, where the moth lay eggs again, are more affected.

The moth larvae do the main harm to plants at night, during the day they have a rest time. Therefore, it is difficult to notice the eggs and caterpillars of the pest during daylight hours. The butterfly lays eggs on the inside of cabbage leaves and it will not be possible to detect this dangerous focus without injuring them. The greenish larvae first scrape off the tissue on the underside of the cabbage leaf, then begin to gnaw holes of various shapes on them.

Particular attention should be paid to measures to combat voracious caterpillars

After the appearance of the scoop, only thick veins remain on the leaves. On young cabbage seedlings, the pest gnaws off the stem, and the plant dies.

During the day, scoop caterpillars gather at the very base of the cabbage head. When autumn comes, they actively penetrate the cabbage head, gnaw through the passages and pollute the head of cabbage with excrement. Such specimens are no longer suitable for storage and consumption.

Important! The holes that the moth larvae gnaw to move inside the fork are very small. This greatly complicates the visual inspection of the cabbage and the ability to notice the pest.

Having penetrated into the core, the caterpillar moves to the stalk, eating away the inside of the vegetable along the way. The forks may appear relatively healthy on the outside but empty on the inside.

The cabbage scoop overwinters in the ground at a depth of 1 m.

Signs of a cabbage scoop

Knowledge of the biological characteristics of the development of the scoop will help determine the time of appearance of the pest. Butterflies appear on the site in late May or early June. Laying eggs begins immediately. After 10-12 days, caterpillars (larvae) will appear from them, which will complete their development within 3.5 to 7 weeks. The first generation of the scoop will pupate at the end of June, the next in October. Then the pupae overwinter, and butterflies will appear on the site again. Focusing on the stages of development of the pest, you can notice in time its appearance on the site:

  1. At the stage of seedling growth, the caterpillars of the cabbage moth gnaw the trunks of the seedlings. As soon as fallen plants are noticed in the garden, it means that the larvae of the scoop have already appeared and attacked the cabbage.
  2. As soon as the heads of cabbage begin to set, places with eaten juicy pulp appear on the leaves. Only thick streaks remain - these are traces of third-instar scoop caterpillars.

If you do not take action on time, cabbage can lose the bulk of its leaves.

The listed signs indicate to the vegetable grower that there is a pest on the cabbage beds.

How to deal with a cabbage scoop

This process is quite complicated. To defeat the enemy of cabbage, different methods of fighting are used:

  • agrotechnical;

  1. Hot pepper. You can take fresh (100 g) or dried (20 g) pods. Pour raw materials with water (1 l) and boil for 1 hour. Filter, leave for 2 days in a sealed container. Before processing cabbage, dilute the resulting volume of solution in 10 liters of water.
  2. Wormwood. Collect the grass in the flowering phase, before preparing the solution, chop the color and stems. Boil 10 liters of water, add 350 g of chopped raw materials, leave for 6 hours. To increase the effectiveness of the scoop remedy, you need to add 1 tbsp. l. liquid soap. Spray the plants 2 times at intervals of 14 days. You can cook wormwood in another way. Insist 100 g of dry bird droppings in 3 liters of water for 2 days. Then boil 1 kg of wormwood in 3 liters of water for at least 15 minutes. Strain the droppings and wormwood, combine the compositions, add water to a volume of 10 liters. Spray the cabbage 2 times after 7 days.

In addition to infusions against cabbage scoop, aroma traps work well. They need to put bait, such as sweet jam or fermented jam, set near the garden. These can be plastic cups, which are important to place at a distance of 1 m from the ridges where the pest is seen. The mixture must be added as it evaporates, after 2 weeks it must be replaced with a new portion.

Some gardeners prefer wood ash infusion (1 glass) + tobacco leaves (200 g) + mustard powder (15 g) + liquid soap (30 g). Mix the components, pour boiling water (19 l), leave for 24 hours.

Important! It is not recommended to apply folk compositions once, it is imperative to repeat the treatment.

To save the heads of cabbage, gardeners should start the fight well in advance of their formation.

Biologicals against cabbage scoop

Manufacturers produce a wide range of anti-cabbage scoop biologics for on-site use. The main advantage of such tools is safety. This applies to humans and garden crops. Each package contains instructions for use, which allows you to competently process cabbage. It is important to remember that the drug should first be diluted in a small volume of water. The second condition is that the last treatment against the scoop should be no later than 5 days before the start of the collection of heads. Fitoverm, Lepidocid, Biostop, Bitoxybacillin are used.

  2. Folk - regular inspection of cabbage, manual collection of caterpillars, bait placement, preventive spraying with herbal infusion.
