Novel thiadiazole compounds are taught and disclosed having the following general structure: ##STR1## wherein R.sub.1 is a halogenated C.sub.1 to C.sub.4 acyclic hydrocarbon radical, wherein the halogen is fluorine, chlorine and/or bromine, R.sub.2 is hydrogen or a C.sub.1 to C.sub.4 acyclic hydrocarbon radical, and R.sub.3 is hydrogen, a C.sub.1 to C.sub.4 acyclic hydrocarbon radical, a halogenated C.sub.1 to C.sub.4 acyclic hydrocarbon radical or cycloalkyl. The compounds show particular utility as agricultural pesticides and, most favorably, as herbicides.
教授和披露了具有以下一般结构的新噻二唑化合物:##STR1##其中R.sub.1是卤化的C.sub.1至C.sub.4无环碳氢基团,其中卤素是氟、氯和/或溴,R.sub.2是氢或C.sub.1至C.sub.4无环碳氢基团,R.sub.3是氢、C.sub.1至C.sub.4无环碳氢基团、卤化的C.sub.1至C.sub.4无环碳氢基团或环烷基。这些化合物在农业杀虫剂中显示出特殊的实用性,最为有利的是在除草剂中。
