A spider mite is pestparasitizing on plant leaves. The female tick can be up to 1 mm in length, the male is 2 times smaller in size. These arthropods are most often milky white, but there are also red, green or orange individuals.

They usually amaze the underside of the sheet - at first, it is covered with white dots on the underside, then the pest begins to weave a web and multiply rapidly.

Ultimately, the cobweb can cover several adjacent leaves, and a wiggling mass from the bodies of ticks and their excrement accumulates along the edges. At the same time, the sheet dries, the plant loses microelements necessary for growth.

The fight against this parasite is usually complex, and its methods depend on which plant was affected, at what stage the infection is and on what in what phase is the plant itself now (flowering, vegetation, etc.). In this article, we will look at how to independently cope with a spider mite on a berry.

  2. Eradicating spraying.
  3. With the arrival of autumn, after the foliage has completely fallen, the grapes are sprayed with DNOC... This can be done in the spring, the main thing is to have time before the buds begin to bloom.
  4. If a tick appears during the growing season, grapes can be treated with special acaricides, among which Sunmight, Omite, Demitan... Plants should be treated with these preparations only if the number of parasites has reached the economic threshold of harmfulness - for grapes it is 5 ticks per leaf.
  5. Folk remedies for combating spider mites. Among them are various decoctions on onion peel, garlic, dandelion... Spraying with such formulations is carried out in the spring, before bud break.

On raspberries

  4. Leaf processing alcohol solution... For this, ordinary medical 96% alcohol is suitable. Before processing, it is imperative to remove all damaged parts of the plant. After a week, the procedure is repeated.
  5. Processing 35% Sulfaride paste.
  6. Fighting ticks with ultraviolet... This pest does not tolerate ultraviolet radiation (therefore, it is located mainly on the underside of the leaf). In order to destroy it, the tree is placed under a special lamp for one and a half to two minutes.
