Applications

Biochemistry: Abamectin acts by stimulating the release of g-aminobutyric acid, aninhibitory neurotransmitter, thus causing paralysis. See M. J. Turner & J.M. Schaeffer in Ivermectin and Abamectin, W. C. Cambell ed., Springer-Verlag,New York (1989) p. 73.
Mode of action: It is an insecticideand acaricide with contact and stomach action. Abamectin has limited plantsystemic activity, but exhibits translaminar movement.
Uses: Abamectin is used in the control of motile stages ofmites, leaf miners, suckers, Coloradobeetles, etc. on ornamentals, cotton, citrus fruit, pome fruit, nut crops,vegetables, potatoes, and other crops. The application rates are 5.6 to 28 g/ha for mite control and 11 to 22 g/ha for control of leaf miners.Abamectin is also used for control of fire ants.
Phytotoxicity: May be phytotoxic topome fruit when mixed with captan.
