Investigations on pesticidal phosphorus compounds I. Fungicides, insecticides and acaricides derived from 3‐amino‐1,2,4‐triazole

Abstract

Abstract The preparation and the biological properties of a number of compounds with fungicidal, insecticidal and acaricidal activities are described. The compounds were prepared by substitution of a phosphorus containing group for a hydrogen atom of the 1,2,4‐triazole nucleus in 3‐amino‐1,2,4‐triazole or a 5‐ substituted derivative thereof. Biological activity was highest when the phosphorus containing group was a bis(dimethylamido)phosphoryl group.
