Phosphorus derivatives of carbamimidothioic-acid esters of the formula
wherein
R and R1 are each independently a methyl or ethyl group or
R and R1 when taken together represent an alkylene group containing 4 to 6 carbon atoms or a group of the formula
wherein
A is oxygen, sulfur or -NR;
R2 and R3 are each independently an alkyl group containing 1 to 4 carbon atoms and
X and Y represent oxygen or sulfur, with the proviso that X and Y are not the same; employed as plant systemic insecticides for the control of sucking and boring-type insects which attack plants of economic importance.
式中R和R1各自独立地为甲基或乙基,或R和R1合在一起代表含有4至6个碳原子的亚烷基,或式中A为氧、硫或-NR的基团;R2和R3各自独立地为含有1至4个碳原子的烷基,X和Y代表氧或硫,但X和Y不相同;用作植物内吸性杀虫剂,以控制侵害具有重要经济价值的植物的吸虫和蛀虫。
