Symptoms of the disease

Unlike many other pests, the whitefly easily betrays itself. To find it, you have to

Just touch the cabbage leaves, and then you will see a whole bunch of white dots literally in a second. If you look under the leaves of a plant, then, with a high probability, you will find many capsules there – these are larvae that have just passed the first stage of their development.

Besides, the appearance of the pest is also evidenced by the product of its vital activity that appears on the cabbage in the form of a white flower. A little later, dark spots begin to appear on the plant – this indicates the appearance and development of the fungus.

The reason for its danger

An adult whitefly is able to completely destroy the plant. Not only does the butterfly eat it, but it can also infect it with various diseases, including chlorosis, leaf deformity, and others. The butterfly carries all these diseases on its paws.

After the plant becomes infected, it can weaken, its growth will deteriorate significantly, and as a result, if you do not take any action, it will die.

In addition, the butterfly actively feeds on plant juices, thus obtaining the necessary nutrients for itself. Moreover, it feeds on both greenhouse crops and those growing in the ground.

The larvae of this insect also pose a great danger to the plant and its development, due to its voraciousness

Chemical measures

If you poison the pests with chemicals, the result can be seen quickly. Simply spraying the plants is enough to eliminate at least some of the parasites. However, it should be borne in mind that treatment with such drugs can scare away and remove not only pests, but also beneficial insects, and if used incorrectly, it can also harm the person himself.

However, the effectiveness of these funds is high. Summer residents allocate special funds such as “Aktara”, “Confidor”, “Akarin”, “Agravertin”, “Iskra”, “Aktalik” and others.

Most likely, you will have to spray the plants with these preparations more than once in order to definitely save them from pests. When using them, we strongly recommend that you follow the safety rules. Treat only with glasses, gloves, mask and gown, and after finishing wash your hands well.

Folk remedies

It is not necessary to use chemicals with a high level of toxicity. Homemade folk remedies can also be used against pests.

If the plants contain a large amount of whitefly, it is recommended to take the maximum of this agent, if you want to carry out prevention, the minimum will be enough. The medium, i.e. 1 liter, is best for plants with thin leaves.

Turpentine should be diluted with 10 liters of water, after which 50-150 grams of grated soap should be added to the liquid, depending on the amount of turpentine. Next, add 1.5 tablespoons of 25% ammonia solution. The solution is ready for use.

Crop residue should not be left after harvesting in the fall. Larvae can remain on them, which is fraught with the subsequent appearance of new pests in large numbers.
