Effect: has the new mechanism, has the effects of tag, not systemic. Mainly inhibit mite fat synthesis, blocking the energy metabolism of mite, and every developmental stage of mites, including the eggs.
 
Characteristic ,
1. The new structure, the unique mechanism of action: ketone mite mites crisis of effective ingredients is season ester, mechanism of action is inhibition harmful mites body fat synthesis. Without interaction between it with existing acaricide resistance, is suitable for used for the prevention and control of becoming resistant to the existing acaricide harmful mites.
 
2. Acaricidal wide spectrum, strong adaptability, mite crisis of starscream, yellow rust spiders,  yellow tea mite, cinnabar variegated leaf mites and two mites etc all have very good control effect, can be used for citrus, grapes and other fruit trees and eggplant, chili, tomato crops in solanaceae, such as mites pollution governance. In addition, the mite dangerous for pear psylla, yu oyster shield pest and leafhoppers pests, such as there is good and cure effect.
 
3. Egg baby and kill, kill the eggs especially excellent results, at the same time also has a good tag for if young mites. Mite dangerous though can't quickly kill female mites, but for the female adult mites have a very good sterilization effect. Female touch into mite eggs are produced by *6% after the drug cannot hatch, died in late embryo.
4. The effective length: mites crisis of effective length, all can control citrus production claw mite damage of *0 ~ *0 days. Mite crisis on plant leaves after the rain resistant, spraying encounter rain does not affect the work after 2 hours of normal play.
5. Low toxicity, low residue, good safety. Under the condition of different temperature on crop is very safe, for people and livestock and crop safety, low toxicity. Suitable for pollution-free production.
6. No cross resistance: but with most pesticides (except strong alkali with cupric pesticides) is mixed with now. Used with existing acaricide, can improve the mite dangerous readily availability, and is advantageous to the mites pollution resistance management.
