The leaves of the cabbage

Reasons

There may be several reasons for twisting the castings:

• aphid pests or white midges wound up;
• the culture is not enough moisture;
• cabbage lacks mineral fertilizers, or there was an oversupply of the last ;
• burn plant leaves with chemicals applied during processing against pests.

Damage to cabbage aphids

If in a summer cottage or a bed, the leaves of a cabbage plant are curled, then most likely it was attacked by aphids. Cabbage aphid is a small, sucking insect of gray-white color, which actively reproduces during the summer. A pest of this kind feeds solely on the sap of the plant.

By laying its eggs on the back of the leaf, it can completely destroy an undeveloped vegetable. The aphid sticks to the shoots and drinks juice from them, as a result of which the edges of the leaves of the cabbage are curled. Also, the affected edges of the plant take a strange, convex shape and become pale in color.

Aphids eaten cabbage suffers from a lack of nutrients, which affects its development. It threatens to stop or slow growth, over time, the plant will simply die.

You need to deal with this scourge immediately, since the insect spreads very quickly and destroys the entire crop. For prevention purposes, it is necessary to carefully examine the leaves for insects, especially at the time of the head of the ovary.

Fight

To get rid of pests, you need to:

1. Be sure to check cabbage leaves. Larvae are laid on the back of the leaf. The sooner a problem is discovered, the better.
2. Treat areas with parasites with the following solutions: a decoction of tobacco dust or dust Metafos.
3. An effective remedy for milk and iodine. On a bucket of water (10l.) Take 0.5l. milk and add 10 drops of iodine. Mix everything and spray on the affected leaves.
4. Folk methods. Decoctions of the tops of potatoes or tomatoes. Can be treated with a solution of infusion of onions or garlic.
5. It is safe for humans to use a drug such as Deltamethrin. It has an active effect on the nervous system of parasites, and not only aphids. Valid for about 2 weeks.
6. Insecticidal soap – a product that does not harm human health and cabbage. Includes fatty acids of flax and olives. Together with the plant-based treatment method, the effect is enhanced.
7. Mandatory cleaning of the soil from weeds and leaves.Parasite larvae may be hiding in them.
8. Caring for the plant. Includes timely watering and loosening of the soil.

Thanks to these methods, the leaves of cauliflower will not curl.

Pests can be disposed of

Sometimes birds are attracted to the site to control the pest. To do this, set feeders and periodically feed the birds.

White midge

This insect looks like a small moth of white color, 1.5–2, and sometimes 3 mm in size. If the leaves of the cabbage are twisted, then the problem can be caused by this pest.

The cat loves warm and hot weather. In mid-summer, when the air temperature rises above 35 ° C, it’s time to take preventative measures. He loves the greenhouse environment, especially if it is poorly ventilated. It hides well from a person. It feeds on the juice of a plant, depriving cabbage of a growth point. Reproduction begins in spring.

It is recommended that all plants be examined for moth larvae. But if they already exist, getting rid of them is not so easy, because the laid eggs are covered with a wax coating.

Fighting

With spraying with chemical preparations in the fight against the pest should wait until the insects hatch. Adult pests are better treated.You can spray a solution of anabazine sulfate, Antelik, or another chemical product intended for these purposes. It is recommended that the mole be lured with ordinary adhesive tape for flies.

Agriculture

If the pest treatment was successful and the leaves of the cabbage still spin, the reason is different.

It is advisable to check the soil for moisture. The lack of sufficient water can also negatively affect the plant. Watering is done strictly at the root. The rain method is rarely needed.

It is worthwhile to saturate the earth with minerals, since an excess of them can also damage. Spray ash on the beds, in order to prevent from diseases and pests. To add humus and chicken droppings, this will significantly improve the vegetation process.

Conclusion
