Recommended four kinds of measures to prevent and control peach tree borers:
First, the medicament is dried with 1 part of 40% omethoate, 1 part of multi-functional plant synergist, 2 parts of water, and mixed liquid. Apply a brush with a brush about 10 cm wide on the trunk. If the bark is rough, you can scrape off old warp skin and apply it. After coating, wrap it with newspaper or plastic film.
Second, the tree trunk injection is to use the iron cone in the trunk from top to bottom, piercing the hole, deep to the xylem, and then use the 8th syringe to inject 40% dimethoate, close the orifice, after 2-3 days can be more than 95% Aphids kill.
Third, the spray can choose to use a lot of chemicals, commonly used in production: 35% of endosulfan cream 1500 times; 50% of the new fog 3000-4000 times; 50% phoxim 1500 times; 40% of the Dimethoate 1500 times; 50% of malathion (marathon) EC 1000 times; 10% imidacloprid (WP) WP 5000 times and so on. In order to improve the control effect, a certain amount of spreading agent can be added to the liquid, and several agents are used alternately to avoid using a single agent.
4. Many natural enemies such as ladybugs, syrphids, grasshoppers, and parasitoids, etc., have a strong inhibitory effect on locusts. Therefore, it is necessary to spray as little as possible with broad-spectrum insecticides and to avoid spraying during natural enemies, in order to protect natural enemies and use natural enemies to eliminate aphids. This is of great significance to protecting the ecological environment of orchards and producing pollution-free green fruits.
