Almost every gardener grows raspberry bushes in his garden. In the process of growing, many are faced with the fact that ticks attack the bushes. Therefore, it is recommended to figure out in advance how to deal with spider mites on raspberries.

Description of the pest

A spider mite is a small arachnid insect whose length does not exceed 0.7 millimeters. There are various types of pests that differ in surface color. Most often, raspberries are attacked by pests that are colored brown. However, there are mites, the back of which has a greenish, yellowish and even milky tint.It is impossible to notice in time that a tick attacked the bushes, since even adults are difficult to see with the naked eye.

There are several stages in the development of this insect:

  • Egg. It has a spherical shape, painted white with a slight brown tint. This stage lasts only 3-4 days.
  • The larva. Small caterpillars emerge from the eggs, which move to plants and feed on their juice. Most of the larvae are pink, but sometimes white individuals are found.
  • Nymph. At this stage, the pest has four pairs of legs. They have a green or red tint.
  • Adult. Adult males, unlike females, have several dark spots on the surface. Their lifespan is 25-35 days.

What is characteristic of the appearance of an insect

It's no secret that spider mites harm raspberry bushes, they pierce the tissue of leaf plates and damage the chloroplast. The following signs of damage to shrubs by this dangerous pest are distinguished:

  • The lower part of the leaf plates is covered with brownish or light spotting, which gradually leads to complete drying and falling off of leaves.
  • Young leaves may marble and curl into a tube.
  • All affected areas of foliage are covered with a dense layer of cobwebs.
  • If you do not get rid of the pest in time, the bushes will be completely covered with cobwebs. In this case, more mites will accumulate on the tips of the leaves, which will eventually move on to he althy plants grown near raspberries.
  • Flower buds on plants with mites dry out quickly and stop growing.

Methods of controlling the parasite on raspberries

To preserve the berries and prevent the shrubs from drying out, we must fight the pest. There are several effective remedies to help get rid of ticks.

Chemicals

The most effective are chemicals that quickly clean plants from any pests. There are four remedies that are popular with gardeners.

Use "Fufanon" can be no more than once every two weeks.

Acrex

Some gardeners think that this remedy is too dangerous, but it is not. "Acrex" is highly toxic only for pests, but not for humans. It has fungicidal properties that help clear shrubs of mites after the first spray.

When processing raspberries, a weakly concentrated solution should be used, and therefore Acrex is mixed with water before use.

Aktellik

This is a complex remedy that is made from the neurotoxins of soil fungi. You can process raspberries with Akarin no more than three times per season. When the trace elements of this biological product penetrate the ticks, they affect the nervous system, which leads to paralysis and death of pests.

Bitoxibacillin

This biological product is the most popular among raspberry growers. "Bitoxibacillin" is used to treat plants attacked by a spider mite.When creating a mixture for spraying seedlings, 15-20 grams of the product is added to 15 liters of heated water. Processing is carried out twice a week, after five in the evening.

To create a liquid that can be sprayed on raspberries, one Fitoverma ampoule will have to be mixed with 7-10 liters of water. Pest protection after treatment will be maintained for a month.

Folk remedies

Sometimes raspberries are processed from a tick with folk remedies that can be made from:

  • Tobacco. It is recommended to use the foliage or young stems of the plant. The infusion is prepared from a liter of water, in which 35-45 grams of ground tobacco leaves are infused. Raspberries are processed every other day for a week.

Prevention is the best cure

It is necessary to deal with the prevention of the appearance of spider mites in order to protect seedlings from pests. All shrubs should be regularly inspected for young ticks.

Some gardeners recommend planting plants around raspberries that would repel insects. These include garlic, lavender, basil, and pennyroyal.
