How to deal with cruciferous pests

Cruciferous pests: fleas, flies, slugs

The most common crops in the garden are cruciferous - cabbage, turnip, radish, radish, swede, horseradish.

They are affected by more than 20 types of pests. And each of them hurts in its own way. The seedlings of radish or cabbage seedlings are attacked by small dark bugs with a metallic sheen - cruciferous fleas.

They overwintered in the topsoil and appeared in early spring. There is still nothing on the beds, and at this time the fleas feed on the leaves of cruciferous weeds, for example, the leaves of a shepherd's purse, which hibernates with leaves. Rape, wild radish and other weeds soon appear.


Then fleas are transferred to cruciferous vegetables. They eat holes on them. Leaves can dry out from this. The worst thing is that if fleas damage the growth point, this can lead to the death of the plant. These beetles lay their eggs in the soil. Their larvae feed on small roots and do no harm. By the middle of summer, the larvae pupate and young beetles appear, which again damage the plants. In the fall, they go to winter.

Begin the fight against flea beetles in the fall, carefully removing weeds and digging up the soil.

In the spring - when shoots appear - water and feed the plants to speed up their growth. To combat the pest, there are several ways: place between the rows of paper flags greased with special caterpillar glue (used to set trapping rings on trees against harmful insects and caterpillars crawling onto trees from the ground. Here is one of the recipes for its preparation: 3 parts of petroleum jelly, 4 parts of var, 20 parts of pine resin, 2.5 parts of rosin.

Var, pine resin and crushed rosin are gradually added to the petroleum jelly melted over the fire, the mixture is kept on fire until a uniform ointment is obtained), or pull the flytrap adhesive tapes. Jumping fleas stick to the trap. To repel the pest, you can spray the plantings with tobacco dust. Process cabbage seedlings pesticide solution.

The pest of cabbage plants is a horseradish leaf beetle, or, as it is also called, babanukha. Dark blue shiny beetles and their dirty yellow larvae eat through holes in the leaves of cruciferous plants. Horseradish is especially badly damaged. In the second half of summer, only veins remain from its leaves, although the plant itself suffers little even with severe damage. Cabbage and radish babanukha are also damaged very seriously. Several generations of these beetles develop over the summer. The fight consists of treating cabbage with pesticide solutions and killing weeds.


Cabbage flies

Cabbage flies are the most dangerous pests of cabbage. They are activated with the beginning of flowering of lilac and colza. After feeding on flowers, the flies lay their eggs on the base of the seedling stalk or on lumps of soil next to it. After a while, larvae appear, which damage the root system, making moves in it. The root rots and the plant turns purple. The fly gives two generations per year. The second generation appears when the plants are already sufficiently developed, so their harm is hardly noticeable. It is difficult to fight the larvae.

Therefore, scare off flies while they are laying eggs. Sprinkle tobacco dust at the base of the stem. Plant celery next to the cabbage, the smell of which is not fond of flies. Water and feed constantly to increase the plant's endurance. Huddle the cabbage to induce the formation of additional roots. When harvesting, do not leave stumps in the ground. Dig up the soil. Cabbage flies cause the worminess of radishes and turnips. Use celery and tobacco dust to scare off these flies during lay.

Belyanka butterflies we have three types. They differ in size, track color, and damage.

Cabbage butterfly

The largest butterfly, the cabbage, has a wingspan of 6 cm. The butterflies emerge from overwintered pupae in late May or June. After feeding and mating, females lay yellow elongated eggs in heaps of 15-100 pieces on the underside of cabbage leaves.

Caterpillars, yellowish with black spots, emerge from them, which devour the leaves, leaving only the largest veins. Then caterpillars pupate, and young butterflies emerge by the end of July - beginning of August. They also leave offspring, and their pupae hibernate.

To prevent colonization of plants by caterpillars, regularly inspect the plants, destroy eggs and larvae. Caterpillars are poisonous, so work with gloves. The butterflies of the whitethroat and the rutabeda are smaller, reaching 4 cm in the wingspan. They fly out earlier than the cabbage - in April - May and lay eggs also on the underside of the leaves, but one at a time. Their caterpillars are green, velvety, and it is very difficult to notice them on the leaves. They are usually given away by the damage inflicted: large irregular holes on the leaves. The second generation also damages the inner leaves of the heads of cabbage. On radishes, turnips and radishes, the harm is most often small, in extreme cases, you can collect the caterpillars by hand. But systematically inspect cabbage and, if necessary, treat with pesticides.

Slugs

Slugs are terrestrial molluscs that damage almost all vegetable crops. They gnaw large holes on the leaves with the help of a grater tongue, and eat young plants whole. In some species, adult or young slugs overwinter, while in others, eggs laid in the soil. Their damage is easily distinguished from others by the shiny traces of mucus that remain on the leaves and on the soil. Since slugs are afraid of drying out, they harm them in the dark. During the day, they hide under leaves, boards, in the soil or in any other shade.

Here is my method. To fight slugs lay out artificial shelters on the site: trimming boards, burdock leaves, slate, matting, etc. For the day, mollusks hide there. During the day, collect pests in a jar of kerosene or strong salt solution. The shells of watermelon, zucchini, peeling cucumbers serve as bait for shellfish, which are laid out between the plants. Slugs gather on them in the late evening. You can pour strips of slaked lime between the plants or dust the soil surface with it. Use metaldehyde from chemicals. Natural enemies of slugs are beetles - ground beetles, frogs and toads, the proximity of which is always useful.

How to deal with a cruciferous flea?

Many gardeners, gardeners on their backyard plots met small black insects that "devoured" radishes, cabbage of various types, horseradish and other cruciferous plants.

These small black insects are called cruciferous flea beetles and are considered the most dangerous and common pests of cruciferous crops.

Cruciferous fleas are especially dangerous in early spring for young shoots, which can be completely destroyed by bugs during this period.

Fleas hibernate in the upper soil layer at the stage of adult beetles under the remains of plants remaining in the garden. Cruciferous fleas emerge from wintering in early spring, during the first warm days, around the end of April and beginning of May. At first, they feed on cruciferous weeds (for example, rape). And as soon as the first shoots appear or gardeners plant early seedlings of cultivated cruciferous plants in the garden, fleas begin to move to them. These pests gladly eat the leaves of turnip, radish, turnip, mustard, horseradish, cabbage of various types, after which, if severely damaged, they dry out and die.

Cruciferous fleas are not only black in color, they are also wavy, notched and light-legged.

What can be done against this type of garden pest?

1) In late autumn, it is imperative to dig up the ground on the personal plot, so that the bugs hiding for wintering are at the soil surface, and in winter they can freeze out.

2) At the first signs of the appearance of a cruciferous flea on cultivated plants, you can sprinkle these plants under them with tobacco dust (makhorka), mixed with ash and phosphoric flour (1: 2). Sprinkling is done 2-3 times every 8 days. Before processing, it is advisable to moisten the plants with water, so that the dusty mixture does not scatter, but is fixed on the leaves and stems of plants.

3) Also, in the fight against a flea, you can use the method of spraying with a solution of table vinegar at the rate of 1 tbsp. 70% vinegar per 10 liters. water..

4) Spraying cultivated plants with dog shampoo (1-2 caps per bucket of water) is considered one of the most effective means of combating cruciferous flea beetles.

All of these methods are advisory in nature, since their use only limits the spread of the cruciferous flea and thereby reduces the harm it causes.

Of the preparations, you can use actellik 50% c.e. (1 kg / ha). Actellic is a drug that fights against a complex of pests, both eating leaves and sucking, incl. and with a cruciferous flea. And also volaton, 50% eq. (0.6 - 1.0 kg / ha), use according to instructions.

The last time spraying with these preparations is carried out 20 days before harvesting.

From all that has been said, we can conclude that in order to completely get rid of the cruciferous flea in the garden, it is necessary to dig up your beds in the fall and, if you can, destroy all cruciferous weeds on your site, which in early spring serve as the first food for these pests.


Dusting plants and soil with tobacco dust

The simplest and unpretentious, but, nevertheless, an effective way to combat insect pests on the site is to dust the plants themselves and the soil around with tobacco dust. You can make this dust yourself if you grow tobacco - the collected leaves just need to be dried and chopped. But it is easier and faster to buy the drug in a specialized store. In this case, you can use both pure tobacco dust and its various mixtures (Tabazol is a mixture of tobacco with ash, Tabagor is a mixture of tobacco with mustard, etc.), which will act not only as an insecticide, but also as fertilizer for soil.

Although all these mixtures are harmless to humans and animals, finely dispersed, pungent-smelling dust can cause allergic reactions, especially if it gets on the mucous membranes. Therefore, it should be sprayed dry or sprayed in solutions in closed clothing, gloves and a respirator.

The maximum effect of dusting with tobacco is observed when growing crops of the cruciferous family, affected by the cruciferous flea and cabbage fly. To combat these insects, cabbage beds (radishes, turnips, radishes, etc.) are simply powdered with tobacco dust at the rate of 20 g per 1 square meter - it can be in its pure form, it can be with various additives such as ash, slaked lime, pepper powder, etc. This treatment is especially useful for plants at the stage of cotyledons and the first tender leaves.

Tobacco dust will help grown plants to get rid of such scourge as slugs. Just groove the honey with rows of plantings and pour tobacco dust into them. A slug will definitely not get over such a "drying ditch" without damage to itself.

Also, dusting of plants with tobacco will not be liked by cabbage butterfly caterpillars, onion fly, onion hoverfly, strawberry leaf beetle (processing should be carried out only in early spring, since tobacco can worsen the taste of berries) and raspberry beetle.

Dusting the beds with tobacco dust is done in cloudy, calm weather, preferably in the evening. It is not recommended to carry out such processing more than 2-3 times per season (this should be done at intervals of 1-2 weeks).


Pests of cruciferous crops: control and prevention

Author: Natalya 05 February 2019 Category: Plant pests

Gardeners work hard all season, growing crops, and how sad it is when, with the onset of autumn, it turns out that the vegetables are spoiled by some pests. It often happens that pests occupy a plant at the stage of maturation, when it is no longer possible to carry out treatment with chemical preparations. In this case, non-toxic folk remedies can help. In the struggle for the harvest, it is very important to be able to identify the pest by appearance. In this article, we will introduce you to the five most dangerous enemies of cabbage crops and tell you how you can fight them.


Pests of cabbage, turnips and radishes

But who can spoil the harvest of cruciferous crops if you do not take the measures described in the table below in time.

Belyanki (cabbage, turnip)

Biological

Eggs and caterpillars are collected from the leaves of the affected plant. After that, the cabbage is treated with mustard infusion (100 g of mustard must be dissolved in 10 liters of water, infused for 3-5 days, then diluted with cold water in a 1: 1 ratio). Spraying with Fitoverm preparations (16 ml / 100 m2).

Spraying with Kinmix (2-3 ml per 4 l of water). Processing is carried out in dry, calm weather.

Cabbage fly (summer, spring)

Biological

The beds are watered with a salt solution (200 g per 10 l of water), after which they are sprinkled with ash. Also, the soil around the plants must be loosened regularly. Landing between the rows of cilantro, garlic, caraway seeds, mint will help.

Introduce Zemlin into the soil (to a depth of 10 cm) (mix 3-5 g with sand in a ratio of 1: 5).

Biological

Caterpillars and eggs of scoops are collected by hand and destroyed (the optimal time is morning or lunch on a cloudy day). Butterflies are caught on molasses or on night fires. For the destruction of eggs, various trichograms are used. Plants are treated with biological pesticides: Bitoxibacillin, Lepidocid, Fitoverm. For prevention in the fall, the beds are carefully dug up.

Treatment of infected plants with drugs Alatar, Kinmiks, Fufanon-Nova, etc. The procedure is repeated at intervals of 5-7 days, it is best to spray the plants in the evening on a dry day.

Fleas (cruciferous, wavy, light-footed, black)

Between the veins of the leaves of cabbage, radish, turnip, radish, daikon, bite marks (holes) are visible. Over time, the plants dry out.

Biological

Marigolds, nasturtium, and calendula are planted next to vegetable crops. Early maturing varieties are weekly treated with tobacco or ash infusion. A solution of 9% vinegar (0.5 liters per 10 liters of water) and a decoction of tomato tops are also effective. The soil is dusted with naphthalene (50 g per 10 square meters).

Good results can be achieved with the help of drugs - Aktara, Alatar, Aliot, Carbocin, Fufanon-Nova.

Cabbage moth

Biological

In the fall, deep plowing of the soil is carried out. They completely destroy weeds and the remains of cruciferous crops. Plants are treated with a solution of soap and ash, as well as an infusion of wormwood. Plants with a pest-repelling odor, such as lavender, are planted near cruciferous plants. They are treated with Bitoxibacillin, Lepidocid and Fitoverm drugs.

Treatment with drugs Alatar, Antitlin, Gerold.

Cabbage aphid

Biological

Weed control. Compliance with agricultural techniques for the cultivation of crops.

Treatment of plants with preparations Aliot, Antitlin, Iskra (according to the instructions).

Green swede barid

Notches appear on the apical buds, leaf petioles and plant stems. Damage to the stalk inside the cabbage.

Biological

Deep plowing of the soil in the autumn. Complete destruction of weeds and remains of cruciferous crops. Compliance with agricultural techniques of plant cultivation.

Treatment with Kinmix, Inta-Ts-M and Fufanon-Nova preparations according to the instructions.


Description and control of beetles - plant pests that eat tree roots

Such parasites are dangerous because it is quite difficult to recognize their presence on plants, since they damage the root system, not the leaves. We suggest considering the most popular representatives.

Medvedki

Bears (Gryllotalpidae) are large brown insects, which are also often called crayfish. The parasites lead an underground lifestyle, and the larvae are also deposited there. Due to the digging of underground tunnels, bears harm the roots by eating them. There are even cases when they can eat even the seedlings of plantations, especially young seedlings.

You can fight the bears by placing various traps (containers with honey, beer) on the territory. The tunnels where the crayfish are hiding must be spilled with an infusion of onions or garlic. The use of insecticides - "Medvetoks", "Rembek" or "Antimedvedka" is also practiced. The preparations are laid out in the holes when planting young trees or seedlings.

Beetles or may beetles are plant pests

Beetles (Melolonthinae) are another pest of trees and shrubs that feed on their roots. As a result of the beetle attack, trees begin to develop worse, and young seedlings may die.

To deal with beetles, it is best to take an integrated approach. The installation of light traps, deep digging of the soil, where plants can hide, are popular. To treat trees, biological insecticides are used, as well as chemical preparations - "Zemlin", "Antikhrushch", "Bazudin".
