Abstract
New derivatives of hydrazinium phosphites, their preparation and fungicidal compositions in which they are present are described. The new fungicidal derivatives have the formula ##STR1## in which R.sub.1 =H, or an alkyl radical containing from 1 to 4 carbon atoms, and R.sub.2 =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 R.sub.1 and R.sub.2 to simultaneously represent a hydrogen atom. These products can be used in agriculture for combating fungal diseases in plants.
