The invention provides the acaricidal thiadiazoles of the formula: ##STR1## (where: R.sup.1 and R.sup.2, which may be the same or different, are each hydrogen, optionally-substituted alkyl of 1 to 10 carbon atoms, or optionally-substituted phenyl, of R.sup.1 is alkylthio of 1 to 6 carbon atoms; R is an ester-forming group; Y is oxygen or sulphur; and the carbamate grouping is in the 3- or 4-position on the phenyl ring), processes for their preparation and compositions containing them.
该发明提供了具有以下结构的螨虫杀灭
噻二唑类化合物:##STR1## (其中:R.sup.1和R.sup.2,可以相同也可以不同,分别为氢、1至10个碳原子的可选择取代的烷基或可选择取代的苯基,其中R.sup.1为1至6个碳原子的烷
硫基;R为酯基;Y为氧或
硫;而
氨基甲酸酯基位于苯环的3-或4-位置),以及它们的制备方法和含有它们的组合物。
