Novel substituted N-alkyl-N-alkoxyamidophosphonates or -thiophosphonates and N-alkyl-N-alkoxyamidophosphates or -thiophosphates of formula ##STR1## wherein R is C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, R.sub.1 and R.sub.3 are each independently of the other C.sub.1 -C.sub.4 alkyl, R.sub.2 is hydrogen, C.sub.4 -C.sub.4 alkyl, or when taken together with R.sub.1, forms the radical --(CH.sub.2).sub.4 --; and X and Y are each independently of the other oxygen or sulfur, with the proviso that at least one of X or Y is sulfur if R.sub.2 is hydrogen. The preparation of these compounds is described, as well as the use thereof in pest control, especially for controlling insects and representatives of the order Acarina.
本发明涉及一种新型替代N-烷基-N-烷氧基酰胺基膦酸酯或硫代膦酸酯和N-烷基-N-烷氧基酰胺基磷酸酯或硫代磷酸酯,其化学式为##STR1##其中,R为C.sub.1-C.sub.4烷基或C.sub.1-C.sub.4烷氧基,R.sub.1和R.sub.3各自独立地为C.sub.1-C.sub.4烷基,R.sub.2为氢、C.sub.4-C.sub.4烷基,或者与R.sub.1一起形成基团--(CH.sub.2).sub.4--;X和Y各自独立地为氧或硫,但当R.sub.2为氢时,X或Y至少有一个为硫。本发明还描述了这些化合物的制备方法,以及其在害虫控制中的应用,特别是用于控制昆虫和螨类。
