Raspberries are a very tasty berry, but the pleasure is spoiled by worms that call the tasty fruit their home.
Most often, this worm is the larva of the raspberry fly or raspberry beetle.
For this reason, it is necessary to carry out prevention to reduce the number of these unwanted guests.
The first method requires quite a lot of effort - you need to take a sheet of oilcloth or a large sheet of cardboard. We lay it under the bush and shake it - most of the larvae will fall from the branches and berries themselves.
The second remedy is potassium permanganate. It is safe and relatively effective. Treat the onion with the solution to deal with pests.
The third method is to make an infusion of wormwood and mustard. Take 500 grams of wormwood from your plot and put it in a bucket, and also add 2 tablespoons of mustard powder.
These simple methods will allow you to eliminate most pests without causing damage to the bush.
