Immediately after the flowering season of peach trees, peach trees are prone to produce aphids, which affect the yield of their fruits. So, how to completely control peach aphids?
Four measures are recommended to strictly control peach tree mites:
1. Apply 40% omethoate to the drug, add 1 part of multi-functional plant synergist, add 2 parts of water, mix and mix into a liquid. Use a brush to apply a 10 cm wide medicine ring on the trunk. If the bark is rough, the old skin can be scraped off and then applied. After coating, wrap it in newspaper or plastic film.
Second, the peach tree trunk injection is to use the iron cone on the trunk to puncture the hole from the top to the bottom, deep into the xylem, and then inject 40% dimethoate with a No. 8 syringe, close the orifice, 95% after 2 to 3 days The above mites kill.
Third, spray agents can choose to use a lot of drugs, commonly used in production: 35% endosulfan 1500 times liquid; 50% sputum fog 3000 ~ 4000 times liquid; 50% phoxim 1500 times liquid; 40% Omethoate 1500 times solution; 50% malathion (marathon) emulsifiable concentrate 1000 times solution; 10% imidacloprid (pampoo) wettable powder 5000 times solution. In order to improve the control effect, a certain amount of spreading agent can be added to the liquid medicine, and several agents should be used alternately, and a single agent should be avoided as much as possible.
Fourth, the natural enemies of the protection of natural enemies, such as ladybugs, scorpion flies, grasshoppers, parasitic wasps, etc., have a strong inhibitory effect on aphids. Therefore, it is necessary to spray a broad spectrum of pesticides as little as possible and avoid spraying during periods of natural enemies to protect natural enemies and use natural enemies to eliminate mites. This is of great significance for protecting the ecological environment of the orchard and producing pollution-free green fruits.
