Phosphate ester based insecticides and - fungicides

摘要

Title based compositions contain a proportion of compound I, with the general formula (in which R1 and R2 are resp. an alkyl gp with 1-6 C atoms or a cycloalkyl gp with 1-6 C atoms, X = C or S, Z = H or CH3 gp and Y is an aralkyl gp or a gp of general formula II, in which W = H or halogen or a nitro or an alkyl gp with 1 - 4 C atoms. These Compounds are active general herbicides, especially for rice cultivation at concns. of 20-40 Kg/ha but show more selective behaviour at 2.5-kg/ha. As fungicides a concn. of 40-600 g/10a is preferred.
