What kind of medicine should be used to eliminate the tea-wing bug?

Tea-winged bug not only smells bad, but also poses a great threat to fruit trees and crops. So what medicine can we use to destroy them?

1. What kind of medicine should be used to eliminate the tea-wing bug?

The available drugs for killing tea wing bugs are: thiazine, bifenthrin, endosulfan, methomyl, "741" aerosol, urea No. 3, Lesbon, dichlorvos EC insecticides, phoxim and so on.

Second, the harm of tea wing bug.

The main targets of tea-winged bug are apple, pear, Hawthorn, peach, pomegranate, citrus and other fruit trees, as well as a variety of forest trees, cash crops and vegetables. When eroded, adults and nymphs suck the sap of leaves, shoots and fruits, and when leaves and shoots are killed, the tree is often weakened. The young fruit is deformed, and the injured part often hardens and tastes bitter. Lose its edible value.

Third, how to control tea wing bug

1. The fruit can be bagged by protecting the fruit. Pay attention to choose different fruit bags according to the characteristics of different fruit trees. It is best to choose a large fruit bag to make the fruit grow in the bag, and there should be a 2cm gap between the fruit and the bag to prevent the tea wing bug from being harmed by the bag.

2. Artificial hunting was carried out in spring to eliminate the overwintering adults, destroy the eggs of pests in spring and summer, and concentrate on trapping and killing insects in autumn.

3. The natural enemies of tea-wing bugs are parasitic wasps, which can collect parasitoid eggs and put them in a container (covered with gauze). After the parasitic bees are feathered, they will be put back into the orchard.

4. in addition to the above methods, drugs can also be used to kill tea-wing bugs. In winter, 50% phoxim EC or 80% dichlorvos EC insecticides can be mixed with sawdust at 1:3 to fumigate unmanned orchards, and doors and windows must be closed for more than 24 hours. Spray and seal off the trees outside the fruit trees. If it is the period of high incidence of insect pests, the plants should be sprayed with thiazide, bifenthrin, endosulfan, methomyl, "741" aerosol, cypermethrin 3 and Lesben.

The prevention and control of tea-wing bugs need to be carried out all the year round, from eggs to adults. Read the instructions before using the medicine, and don't use it blindly.
