bulletIndications & Usage
The avermectins are insecticidal/miticidal compounds derived from the soil bacterium Streptomyces avermitilis. Abamectin is a natural fermentation product of this bacterium. It acts as an insecticide by affecting the nervous system of and paralyzing insects. Abamectin is used to control insect and mite pests of citrus, pear, and nut tree crops, and it is used by homeowners for control of fire ants.

Abamectin is a stomach and contact poison to mites and insects. It decomposes and dissipates rapidly with its application on foliar surface. When the active ingredient penetrates into the tissue, it may persist in the tissue and may be transferred. Because of this effect, the product has a prolonged efficacy against harmful mites and phytophagous insects. Its mode of action is different from other pesticides. It disturbs the neurophysiologic activities of the pests, stimulate the release of GABA and block the transmition of motive nervous impulse. The adult mites larvae mites and larvae insects will be paralyzed and will not move or feed to die in 2-4 days being exposed to the product.
