Abamectin is used to control insect and mite pests of a range of agronomic, fruit, vegetable and ornamental crops, and it is used by homeowners for control of fire ants. Abamectin is also used as a veterinary antihelmintic. Resistance to abamectin-based antihelmintics, although a growing problem, is not as common as to other classes of veterinary antihelmintics. The benzoate salt emamectin benzoate is also used as an insecticide.
Abamectin is a mixture of avermectins containing more than 80% avermectin B1a and less than 20% avermectin B1b. that is why the certificate of analysis only shows that the rate as α value (calculated as B1a / B1b). 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.
Acts by stimulating the release of g-aminobutyric acid, an inhibitory neurotransmitter, thus causing paralysis.
