NEW DERIVATIVES OF HYDRAZINIUM PHOSPHITES, METHOD OF PREPARING THE SAME AND FUNGICIDE PREPARATIONS CONTAINING THESE DERIVATIVES.

摘要

New derivatives of hydrazinium phosphites, their preparation and fungicidal compositions in which they are present are described. The new fungicidal derivatives have the formula IMAGE in which R1=H, or an alkyl radical containing from 1 to 4 carbon atoms, and R2=H, or a phenyl nucleus which is optionally substituted by one or more of the following atoms or radicals: halogen, alkyl radicals, containing from 1 to 4 carbon atoms, and the nitro radical; however, it is not possible for R1 and R2 to simultaneously represent a hydrogen atom. These products can be used in agriculture for combating fungal diseases in plants.
