Combating pests with 2-substituted-alkyl-5-substituted-N,N-dimethylcarbamic acid O-pyrimidin-6-yl esters

摘要

2-Substituted-alkyl-5-substituted-N,N-dimethyl-carbamic acid O-pyrimidin-6-yl esters of the formula <IMAGE> in which R and R2 each independently is alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl and R1 is hydrogen or alkyl, which possess pesticidal properties. The hydroxypyrimidines corresponding to the esters are also new.
