Ectoparasiticidal compsns. contg. tri (cyclo) alkyl tin triazoles - esp. for mites and flies resistant to chlorohydrocarbon pesticides

摘要

Compsns. for control of ectoparasites contain =1 triazole deriv. of formula (I) (R1, R2 and R3 are each alkyl or cycloalkyl; the Sn atom is bonded to one of the triazole N atoms and n is an integer 0). (I) are esp. useful for control of mites causing mange, flies and fly larvae which are resistant to chlorohydrocarbon pesticides such as lindane e.g. Psoroptes cuniculi, P. Ovis, Chlorioptes bovis, Stomoxys calcitrans and Lucilia caprina. Tricyclohexyltin triazole, the pref. cpd., is already known as a fungicide and as an insecticide and acaricide.
