APPLICATIONS

Biochemistry Acts by stimulating the release of g-aminobutyric acid, an inhibitory neurotransmitter, thus causing paralysis. See M. J. Turner & J. M. Schaeffer in Ivermectin and Abamectin, W. C. Cambell ed., Springer-Verlag, New York (***9) p. *3.  Mode of action Insecticide and acaricide with contact and stomach action. Has limited plant systemic activity, but exhibits translaminar movement.  Uses Control of motile stages of mites, leaf miners, suckers, Colorado beetles, etc. on ornamentals, cotton, citrus fruit, pome fruit, nut crops, vegetables, potatoes, and other crops. Application rates are 5.6 to *8 g/ha for mite control, *1 to *2 g/ha for control of leaf miners. Also used for control of fire ants. Phytotoxicity May be phytotoxic to pome fruit when mixed with captan.  Formulation types EC.  Compatibility Not compatible with captan.  

 

ANALYSIS

Product analysis by hplc with u.v. detection. Residues by conversion to a fluorescent product followed by hplc with fluorescence detection. See T. Wehner et al. in Comp. Anal. Profiles, Chapt. 4.

环境命运

动物 快速消除（*6 小时内 *****0%），主要通过粪便排出;尿排泄量为 0.**1.4%。植物 三种不同植物中的每一种的降解/代谢都是相似的，主要通过植物表面的光解发生。因此，残基的定义表示为阿维菌素 B1 及其 8,*-Z-阿维菌素 B1 光异构体的组合残基。土壤/环境 与土壤紧密结合，被土壤微生物迅速降解。无生物蓄积。
