Abamectin is bio-pesticide, which can be mixed with a variety of insecticides or add a small amount of detergent that help moist abamectin powder and increase its adhesion to improve efficacy. It cannot be mixed with fungicides, or most of biological pesticides are fungi which are the main ingredient of abamectin would be killed by fungicides, then the pesticide loses its effect; it can not be mixed with alkaline pesticides as the most fungi in the drug live in acidic conditions that alkaline pesticides will destroy the habitat of these microorganisms, causing inactivation of fungi, pesticides failure.

The first advantage of abamectin is efficient and can kill a variety of pests, including lepidoptera, diptera, homoptera, coleoptera insects, spider mites, rust mites, and also effective at killing a variety of parasitic nematodes; second, unlike the potency of other pesticides, it is not easy to cause drug resistance; third, because the medicament sprayed onto the surface of plants can quickly decompose, it is safer to the predators, less pollution to the environment, and the plant will not cause injury even with more than 10 times the amount of usage.

Cons: first, abamectin kill pests slowly that it takes 2 to 4 days from slow movement to food refusal to death, so farmers tend to think that the efficacy is bad; second, the original drug is of high toxicity that various pesticides keep the content of the active ingredient very low to reduce the toxicity, but safety use is still needed.

Advantages and Disadvantages of Abamectin

Abamectin cannot be abused though it is a good medicine. Currently it is expensive, usually utilized in vegetable fields for the control of diamondback moth, cabbage worm, leafminers, armyworm, spider mites, mites; on the fruit trees for prevention and treatment of a variety of rust ticks, fleas, aphids, mealybugs and lepidopteran pests; and pests difficult to control with other agents or pests have anti-drug resistance to other common agents such as spider mites and cotton bollworms.

In recent years, a series of mixing pesticides containing avermectin have been developed such the one mixed with kinds of pyrethroids agents or chlorpyrifos, etc., are often able to accelerate the death of pests; increasing the tags or other modes of action; delaying the drug resistance, worth to be put into applications.

In addition, from the development of varieties, there is one called emamectin benzoate, another similar drug called methylamineavermectin which has higher insecticidal activity than abamectin and it’s confirmed by tests, less toxic to humans and animals, having a good application prospect.

The insecticidal activity of abamectin is 5~50 times higher than the conventional pesticides, only 0.1~0.5g active ingredient per mu for the usage amount. There are 84 species of abamectin insecticide spectrum, which can effectively prevent diptera, homoptera, coleoptera, lepidoptera pests and a variety of mites. In the first alternative varieties of highly toxic pesticides, avermectin is recommended for the prevention and treatment of rice leaf roller and cotton spider mites; emamectin are recommended for bollworm moth and small levin. It is noteworthy that the ministry ofagriculture is organizing experts to demonstrate for the recommendation of avermectin applications in the fields of rice. If all goes well, the forbidden use of avermectin which has lasted for a long time will no longer be a problem.
