ORGANOPHOSPHORIC ACID ESTERS AND THEIR USE AS INSECTICIDES, ACARICIDES AND NEMATOCIDES

摘要

The invention provides as new compounds the organophosphoric acid esters of the general formula in which R1 represents alkyl with 1 - 8 carbon atoms, R2 represents alkyl with 1 - 8 carbon atoms or alkoxyalkyl with 2 - 8 carbon atoms, X represents hydrogen, halogenoalkyl with 1 - 8 carbon atoms or alkoxy with 1 - 8 carbon atoms, and Y represents halogen. The compounds of the formula have been found to have excellent insecticidal, acaricidal and nematocidal activities.
