Advantages and disadvantages of avermectin

It can not be mixed with fungicides because the majority of biological pesticides are fungi. Once be mixed with fungicides, fungi, its main component will be killed by fungicides, making pesticide effectless. It also can not be mixed with alkaline pesticides for most fungi in drugs are living in acidic conditions and being mixed with alkaline pesticides will destroy the living conditions of these microorganisms, making the fungi inactivate and pesticides effectless.

Avermectin’s first advantage is efficient and can kill a variety of pests, including Lepidoptera, Diptera, Homoptera, Coleoptera pests and mites, rust mites, also an efficient pharmacy to kill a variety of parasitic nematodes; the second advantage is that the potency is different with other pesticides, not easy to produce drug resistance; the third advantage is safe, because the medicine spray to the plant surface can be quickly decomposed, so it is safer to the natural enemies, less pollution to the environment, even with more than 10-fold would 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 is poor; second, the original drug toxicity is large, various medicines are in a low content active ingredients to reduce drug toxicity level, but still need to note the safety while using.

Avermectin should not be abused although it is a good medicine. Currently, it is still more expensive, generally in vegetable fields used for controlling diamondback moth, cabbage worm, leafminers, moth, spider mites, in the prevention and treatment of a variety of fruit trees mites, rust ticks, fleas, and aphids and mealybugs lepidopteran pests, as well as some of the other crops is difficult to control with other agents or have been produced resistant to commonly used drug, such as spider mites cotton bollworm. Other places are as much as possible to avoid using this drug. It can be considered a form of protection for the environment.

In recent years, abamectin supplier developed a series hybrid avermectin-containing insecticides, such as mixed with a variety of pyrethroids mixed with chlorpyrifos, etc., are often able to play a role of accelerating pests death; increase tag or other mode of action; delaying pest produce resistance, it is worth to apply.

In addition, from the development of varieties, one is called emamectin benzoate, the other called rich emamectin similar agents have been through tested demonstrating the insecticidal activity is higher than abmectin, have less toxic to humans and animals, with a good prospect.

Avermectin has high 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 avermectin has 84 species, can effectively prevent Diptera, Homoptera, Coleoptera and Lepidoptera and a variety of mites and other pests. In the first batch of high-toxic pesticide alternatives varieties, avermectin is recommended for preventing and treating leaf roller, cotton spider mite, emamectin is recommended for preventing and controlling bollworm and small moth. It is noteworthy that the Ministry of Agriculture is organizing experts to demonstrate avermectin recommended applications in the rice field, if all goes well, for a long time the use "off-limits" of avermectin will be broken.
