Spirotetramat

Spirotetramat is an insecticide. It is active against C. pyri nymphs in vitro (LC50 = 6.51-12.53 mg AI/L) and induces mortality of C. pyri nymphs in European pear (P. communis) fields by 99.2% 15 days after application at a concentration of 27 g/hectare. Spirotetramat also reduces O. insidiosus embryonic viability and nymph survival. It exhibits aquatic toxicity, increasing protein levels of glutathione peroxidase (GPX) and superoxide dismutase (SOD), decreasing levels of malondialdehyde (MDA), and inducing lethality in Chinese toad (B. gargarizans) tadpoles (LC50 = 6.98 mg/L). Formulations containing spirotetramat have been used in the control of insects in agriculture.Formal Name: carbonic acid, cis-3-(2,5-dimethylphenyl)-8-methoxy-2-oxo-1-azaspiro[4.5]dec-3-en-4-yl ethyl ester.
