How to deal with a spider mite on raspberries with folk remedies and drugs
Almost every gardener grows raspberry bushes on the territory of 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 a spider mite on raspberries.
Description of the pest
A spider mite is a small arachnid insect, the length of which 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 ticks, 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 of development of this insect:
- Egg. It has a spherical shape and is white with a faint brown tint. This stage lasts only 3-4 days.
- Larva. Small caterpillars emerge from the eggs, which move to plants and feed on their sap. Most of the larvae are colored pink, but sometimes white individuals are found.
- Nymph. At this stage, the pest develops four pairs of legs. They have a green or red tint.
- An 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 is no secret that spider mites harm raspberry bushes, they pierce the tissues of the 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 blades is covered with brownish or light spotting, which gradually leads to complete drying out and foliage falling off.
- Young leaves can turn marbled 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. At the same time, more mites will accumulate on the tips of the leaves, which will eventually move to healthy plants grown near raspberries.
- Flower buds on plants with mites dry out quickly and stop growing.
Methods of dealing with the parasite on raspberries
To preserve the berries and prevent the shrubs from drying out, it is necessary to fight the pest. There are several effective remedies that can help get rid of ticks.
Chemicals
The most effective are chemicals that quickly cleanse plants of any pests. There are four drugs that are popular with gardeners.
"Fufanon"
This is a drug with a wide spectrum of action and is used for spraying berries. Experts recommend using Fufanon not only to eliminate ticks, but also to fight other gnawing parasites. After spraying, all mites on the bushes should die within an hour.
You can use "Fufanon" no more than once every two weeks.
"Akreks"
Some gardeners believe that this remedy is too dangerous, but this is not the case. "Acrex" is highly toxic only for pests, but not for humans. It has fungicidal properties that help clear mites from shrubs after the first spray.
When processing raspberries, a weakly concentrated solution should be used, and therefore, before use, "Akrex" is mixed with water.
"Actellik"
Contact drug used to work with raspberries and other berries. Actellik effectively fights against the most common pests faced by many gardeners and gardeners. A distinctive feature of the product is considered its versatility, due to which "Actellik" is used both in small garden plots and for industrial purposes.
"Antio"
Twenty percent emulsifiable concentrate with a specific odor. To create a working solution, a liter of the drug is mixed with 7-8 liters of warm water. Active protection "Antio" lasts for 14 days and therefore re-spraying is carried out only after two weeks.
Biologicals
Instead of chemicals, biologicals can be used that are not made with chemicals.
"Akarin"
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 microelements of this biological product penetrate inside 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 in 15 liters of heated water, 15-20 grams of the product are added. Processing is carried out twice a week, after five in the evening.
Fitoverm
Domestic drug, which contains aversectin. The product is sold in small ampoules of 10 milliliters. To create a liquid that can be sprayed on raspberries, one ampoule of Fitoverma will have to be mixed with 7-10 liters of water. Pest protection after treatment will last for a month.
Folk remedies
Sometimes raspberries are treated against ticks with folk remedies, which can be made from:
- Tobacco. It is recommended to use 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 insisted. Raspberries are processed every other day for a week.
- Pepper. From the ripe fruit of bitter peppers, you can prepare an effective infusion against ticks. To do this, it is enough to add 150 grams of dry pepper to two liters of water.
Prevention is the best treatment
It is necessary to deal with the prevention of the appearance of spider mites in order to protect the seedlings from pests. All shrubs should be regularly examined and checked for juvenile ticks.
It is also recommended to periodically process the berries with biological products and folk remedies.
Some gardeners recommend planting plants near raspberries that would repel insects.These include garlic, lavender, basil, and mint.
