Veterinary 99% up by HPLC Vet GMP Abamectin manufacturer B1a B1b

Details:

Avermectin is a mixture of avermectins containing more than 80% avermectin B1a and less than 20% avermectin B1b. These two components, B1a and B1b have very similar biological and toxicological properties. The avermectins are insecticidal and antihelmintic compounds derived from various laboratory broths fermented by the soil bacterium Streptomyces avermitilis. Avermectin is a natural fermentation product of this bacterium.

Function:

Abamectin has stomach poisoning and contact killing effects on mites and insects, and cannot kill eggs. The mechanism of action is different from general insecticides in that it interferes with neurophysiological activities and stimulates the release of γ-aminobutyric acid, which has an inhibitory effect on the nerve conduction of arthropods. Adults, nymphs and insect larvae of mites will appear paralyzed after contact with abamectin, do not move or feed, and die after 2 to 4 days. Abamectin has a slower lethal effect because it does not cause rapid dehydration of insects. Although avermectin has direct contact and killing effect on predatory insects and parasitic natural enemies, it does little damage to beneficial insects because of the few residues on the plant surface. Abamectin is absorbed by the soil and will not move, and is decomposed by microorganisms, so it has no cumulative effect in the environment and can be used as a component of comprehensive control. It is easy to prepare, pour the preparation into water and stir it for use, and it is safer for crops.
