Avermectin has a 16-membered macrolide with strong insecticidal, acaricidal and nematicidal activity, and a dual-use antibiotic for agriculture and livestock.

Broad spectrum, efficient and safe. It has stomach poisoning and contact killing effect and cannot kill eggs. Its mechanism of action is to interfere with neurophysiological activity, affecting cell membrane chloride conduction, and aminobutyric acid is its site of action.

When the agent stimulates the action site, it blocks the transmission process of the motor nerve information, so that the signal of the central nervous system of the pest is continuously accepted by the motor neurons, and the pest quickly paralyzes, refuses to eat, slows or does not move within a few hours, because it does not cause Insects are rapidly dehydrated, so the lethal effect is slow and usually dies after 24 days.
