## 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‐t
