Combating arthropods with O-alkyl-O-(6-alkoxy-2-cyclopropyl-pyrimidin-4-yl)-(thiono)(thiol)-phosphoric (phosphonic) acid esters or ester-amides

摘要

O-Alkyl-O-(6-alkoxy-2-cyclopropyl)-pyrimidin-4-yl)-(thiono) (thiol)-phosphoric (phosphonic) acid esters or ester-amides of the formula <IMAGE> in which R is alkyl, R1 is alkyl, alkoxy, alkylthio, monoalkylamino or phenyl, R2 is alkyl, R3 is hydrogen, halogen or alkyl, and X is oxygen or sulphur, which possess arthropodicidal properties.
