2. Stem fly. Pest that appears in May-June. He lays eggs in the leaves and tops of young stems. Hatching caterpillars eat the leaves and cause them to dry.

We always use Malathion from many pests in the country. Inexpensive and very effective. We use it infrequently, as we try to prevent the development of pests or use proven folk remedies. But with a strong infection, we always spray the cultures with Carbofos. Helps a lot.

I am afraid to apply chemistry at any stage of growing garden crops. But last summer, the bushes simply attacked the caterpillars and folk remedies were powerless. Neighbor recommended Guapsine. This is a biological product that has almost no negative effect. I bought for 100 rubles a bottle of 500 ml.

I tried to plant mustard in a bucket of water to process garden shrubs. Effect not noticed. If the caterpillars and became smaller, then not much. I had to buy special insecticides, and only then was the result.

How to prevent infections

It is always easier to prevent the development of pests on raspberries than to suffer harvest losses. To protect the crimson bushes, you should follow these recommendations:

1. Crop. Every year before sending the plants for wintering, it is necessary to prune dry and damaged branches.
2. Spring thinning bushes. This will improve air circulation in the root system.
3. Keep the area clean. All rubbish and weeds should be immediately taken out of the garden and burned. Picked plants lying on the beds, contribute to the spread of spider mites.
4. Ensure that the soil is loose. To do this, throughout the growth of raspberries periodically loosen the ground.

Important!

Affected stems should be cut at the root. The exceptions are parts infected with stem gallfly.In this case, pruning should be slightly lower than the characteristic swellings detected.

Regular vegetation control can reduce the number of pests on raspberries. To do this, once a week it is necessary to carefully inspect each hive and, if diseases or pests are detected, immediately remove the affected parts. If various harmful insects are often found on the site, it is possible to treat the stands with special chemicals once a year for prevention. It is best to do this in the spring with the help of Karbofos or Aktellik.

To save the crop from the crimson beetle, I cover the bushes with non-woven material for the period of bud formation. When the flowers begin to bloom, the protection is removed.

Thus, getting rid of caterpillars on raspberries will not be easy. In order to preserve the crop as much as possible and not be zealous with chemicals, it is better to regularly carry out simple methods of prevention. Cleanliness at the site and control over the ripening of plants will be the key to the absence of pests and the generous harvest of not only raspberry berries, but also other crops.
