It is not particularly important whether you are growing cabbage in a summer garden or in a winter greenhouse, you will definitely meet crop pests that will interfere with obtaining the desired result. That is why the topic of our conversation today is cabbage pests and methods of dealing with them.
Each of us dreams of growing a good harvest, stable and high-quality, which will meet our expectations and give us a lot of environmentally friendly vegetables. To do this, we invest money and effort in the development of the soil, the construction of greenhouses, fertilizers and seedlings, but we often remain, so to speak, with the nose and the blame for the pests. Today we will tell you about pests of cabbage and how to deal with them in order to preserve the harvest.
Classic cabbage pests
Serious damage to these insects is already in the seedling seedling phase. These are small bugs that winter in the soil and survive the winter in plant debris. With the onset of heat, they leave wintering places and eat cruciferous on their way. First, weeds, and then cabbage, which we planted in the ground.
An interesting fact is that cruciferous fleas eat cabbage in dry and sunny weather, but they are afraid of moisture and during the rains they simply go to the ground or under the cabbage seedlings, where they experience adversity.
Insects feed on the upper layers of leaf tissue, which is fraught with subtle ulcers on the plant. When seedlings grow up, tears appear on the sites of ulcers. Massive damage of this kind often leads to wilting seedlings and death of plants. If the attack falls on adult plants, they already have enough strength to survive it and show the crop, albeit worse quality.
How to deal with cruciferous flea on cabbage?
To save cabbage from pests, it is necessary to understand that early planting in this case is only good, because by the time the parasites are active, the plants are already more mature and stronger.
Increasing the resistance of cabbage to fleas can be achieved by top dressing with slurry and nitrate.
In order to prevent insects from destroying the crop, it is necessary to pollinate seedlings with dust. For this, hexachloran (12%) is used in a mixture with DDT, processing is carried out at the rate of 10-15 g per 10 m2. If there is no dust, you can replace it with other drugs, for example, mix road dust, furnace ash and sodium silicofluoride (1: 1: 1), and carry out processing at the rate of 10 g per 10 m2. The first treatment occurs at the time of the appearance of fleas, then a few more treatments in increments of a week.
The insect is very similar to a housefly, although smaller in size. Damages the parasite cauliflower and white cabbage, starting in late May. At this point, the fly lays eggs directly on the soil near the cabbage or on the root neck of the plant. After 7-10 days, larvae appear from small heaps of eggs, which attack the roots of the culture. As a result, the root system begins to rot, plant nutritional regimes fail and cabbage dies. The activity of the cabbage fly can be determined by a wilted appearance or by the color of the lower sheet, which becomes a lead color.
How to deal with the cabbage fly
To prevent the insect from harming the cabbage plantings, we need:
- Pollination of plantings with dust, no more than 3-5 g per square meter weekly;
- If cabbage fly larvae are detected, water the culture with a special solution of thiophos (30%), the concentration of which should not exceed 0.03%. The consumption for each plant is about 250 g;
- Water cabbage with chlorophosomes (65%), the concentration of the solution is about 0.15-0.25%, the consumption for the plant is not more than 200 g;
- If there are no such poisons, the soil is sprinkled with mothballs with sand, 1: 7, or lime with tobacco dust (1: 1), not more than 300 g per 10 m2.
This cabbage pest is a small butterfly that starts laying eggs on a cabbage leaf in early June. Each butterfly is capable of producing up to 100 eggs, which are clearly visible on the underside of the leaf in the form of small yellow dots. About a week after laying, a caterpillar emerges from the egg, which feeds on the flesh of the cabbage leaf, drilling through them through holes.
The fight against cabbage moth
Fighting cabbage pest like this should be very effective, because during the warm period, the moth gives up to several generations that cause very serious harm. To fight cabbage moth, you should:
- Treat cabbage from pests with calcium arsenate, about 12 g for every 100 m2;
- Spray chlorophosomes (65%), with a solution concentration of about 0.15%, up to 500 mo per 10 m2;
- You can use entobacterin, which is diluted to a solution state of 0.1-0.4% and is used in an amount of 500 ml for every 10 m2.
Cabbage scoop and cabbage whitewash
Belyanka is a large moth with specks of black on the wings. It rages during the day, when it lays eggs on cabbage leaves in quite serious portions, from 30 to 100 pieces at a time. After 1-1.5 weeks, a caterpillar appears, which quickly eats up the flesh of the leaf, leaving only the veins intact.
A scoop is a nocturnal representative of pests, which acts in approximately the same way. Here are just caterpillars from eggs scoops appear much earlier, after 5-8 days.
Fighting the scoop and cabbage whitewash
Protection of cabbage from pests occurs in the same ways as from cabbage moth. You can use the same means, at the same standards, and you will get an excellent result and save the cabbage crop.
Cabbage aphid is a fairly small parasite, grayish-white in color with a kind of waxy coating. In spring, with the first serious warmth, the aphids are ready to appear in whole colonies, but aphids can suck juice from cabbage, thereby killing it, by mid-summer. Signs of cabbage aphids can be considered small white, and later brown spots, twisted leaves, loss of ovaries.
Methods of dealing with cabbage aphids
Processing cabbage from pests is as follows:
- A solution of anabazine sulfate 0.2% is prepared, the treatment takes place in the amount of 500 ml per 10 m2;
- If there are no chemicals, you can use folk remedies for pests - a decoction of tobacco leaves. To do this, 400 g of tobacco is boiled for 2 hours in 2 liters of water. Further, when the broth cools down, the leaves are drained, and the liquid is poured into a bucket of water, 40-60 g of soap are added and processing is carried out.
Pests of white cabbage and cauliflower - Serious parasitic insects, at any time ready to destroy your crop, and therefore prepare in advance for the fight and learn all the methods.
How to deal with cabbage pests
Now that you know the description of the pests and the signs of their attack on the culture, and 100% understand how to deal with cabbage pests, you only need to carefully prepare yourself, choose a quality remedy for cabbage pests and protect your crop.
