It can not be mixed with fungicides because the majority of biologicalpesticides are fungi. Once be mixed with fungicides, fungi, its main componentwill be killed by fungicides, making pesticide effectless. It also can not bemixed with alkaline pesticides for most fungi in drugs are living in acidicconditions and being mixed with alkaline pesticides will destroy the livingconditions of these microorganisms, making the fungi inactivate and pesticideseffectless. Avermectinsfirst advantage is efficient and can kill a variety of pests, includingLepidoptera, Diptera, Homoptera, Coleoptera pests and mites, rust mites, alsoan efficient pharmacy to kill a variety of parasitic nematodes; the secondadvantage is that the potency is different with other pesticides, not easy toproduce drug resistance; the third advantage is safe, because the medicinespray to the plant surface can be quickly decomposed, so it is safer to thenatural enemies, less pollution to the environment, even with more than 10-foldwould not cause phytotoxicity. Drawbacks:First, the effect to kill pests is slower, pests eat avermectin, first action slow,not feeding, death after 2 to 4 days, farmers always think that the efficacy ispoor; second, the original drug toxicity is large, various medicines are in alow content active ingredients to reduce drug toxicity level, but still need tonote the safety while using. Avermectin shouldnot be abused although it is a good medicine. Currently, it is still moreexpensive, generally in vegetable fields used for controlling diamondback moth,cabbage worm, leafminers, moth, spider mites, in the prevention and treatmentof a variety of fruit trees mites, rust ticks, fleas, and aphids and mealybugslepidopteran pests, as well as some of the other crops is difficult to controlwith other agents or have been produced resistant to commonly used drug, such asspider mites cotton bollworm.

In recentyears, abamectin supplier developed a series hybrid avermectin-containing insecticides, suchas mixed with a variety of pyrethroids mixed with chlorpyrifos, etc., are oftenable to play a role of accelerating pests death; increase tag or other mode ofaction; delaying pest produce resistance, it is worth to apply. In addition,from the development of varieties, one is called emamectin benzoate, the othercalled rich emamectin similar agents have been through tested demonstrating theinsecticidal activity is higher than abmectin, have less toxic to humans andanimals, with a good prospect. Avermectin hashigh insecticidal activity, is 5 to 50 times than the commonly used pesticides,the application amount of every hectare is only 0.1 ~ 0.5g active ingredient. The insecticidal spectrum of avermectinhas 84 species, can effectively prevent Diptera, Homoptera, Coleoptera andLepidoptera and a variety of mites and other pests. In the first batch of high-toxicpesticide alternatives varieties, avermectin is recommended for preventing andtreating leaf roller, cotton spider mite, emamectin is recommended forpreventing and controlling bollworm and small moth. It is noteworthy that theMinistry of Agriculture is organizing experts to demonstrate avermectinrecommended applications in the rice field, if all goes well, for a long timethe use "off-limits" of avermectin will be broken.
