How to deal with pear gall mites
Reasons for the appearance
The main danger of these bugs is that they independently move from one tree to another. Their appearance and reproduction provoke the following factors:
- a very large number of phosphorus-compatible fertilizers;
- irregular pruning of the crown;
- the introduction of an excessive amount of stimulant preparations for trees.
Sometimes drugs that are used to control other pests do not pose a danger to the pear gall mite. They only destroy its direct enemies - dragonflies, ground beetles, etc.
Due to the fact that these pests are very small, they are difficult to recognize. The pear gall mite resembles white or light pink worms with four legs that are closer to the head and help them move.
First, small wavy blisters (galls) of 0.18 to 3 mm in size are formed on the pear leaves. Under them can be adult worms or previously laid female eggs. At first, these bubbles merge with the color of the leaves, then they darken and turn black. As a result, the parasites very dry the leaves and they fall.
Beetles can also hide under the bark of a tree, especially in winter. They multiply there and suck out the cellular sap from the buds of the tree. This leads to the fact that the kidneys become very small or do not open at all.
Ways to fight
Means of struggle against pear mites are the correct and timely care of the tree. If damaged leaves are noticed, they must be removed immediately and burned. Branches that are badly infected should also be pruned.
There are also more radical measures to combat pear mites - chemical treatment and folk methods. These spraying methods should be carried out in the morning or in the evening. The best weather is dry, sunny, but you can carry out the procedure in cloudy weather. Because in the sun, the effectiveness of combating parasites decreases and droplets of solutions burn leaves.

- Vermitek. A chemical that affects the reproduction of various pests. Advantage - resistant to washing off by rain.
Processing should be carried out no more than 1 time in 2 weeks. Do not forget about safety measures. All actions must be performed with gloves, a face mask and clothing as closed as possible. Be sure to change the preparations for treating the tree so that the parasite does not develop immunity to them.
Pest injection has also recently become popular. The drug gets into sap flow and causes irritation of the mucous membrane in pests. This method is distinguished by the efficiency of delivering drugs to different parts of the tree.
A very good remedy is an infusion of dandelions. You need to take 1 kg of fresh leaves of dandelions and fill them with 3 liters of water. Leave to insist for 3 days. Before processing the pear, 100 ml of liquid soap should be added to the filtered solution.
