TRIAZOLE PHOSPHONATE PESTICIDES

摘要

Compounds of formula (I), where Tr is optionally substituted 1,2,4-triazol-1-yl or 1.2.4-triazol-3-yl; A is a) Q, where Q is an optionally substituted chain containing 3 to 6 atoms, and in which (i) when the chain is of 3 atoms, at least one of the chain atoms is a hetero atom, (ii) when the chain comprises 4 carbon atoms, then the second carbon from the triazole is not substituted by optionally substituted hydroxy, and (iii) when the chain is of 3 to 5 atoms, the phospho group is not attached directly to an oxygen atom; or b) an optionally substituted three membered carbon chain or ring, in which two optional substituents can together with the chain atoms form a carbocyclic ring; and in which when A is a chain, various proviso apply, can be used for combating fungi. The compounds have been shown to be inhibitors of imidazole glycerol phosphate dehydratase. Many of the compounds are novel and these also have other pesticidal activity.
