Herbicidally active thiolcarbamates are employed in combination with certain 4-phenyl-1,2,3-thiadiazoles having the formula ##STR1## in which R.sup.4 is selected from the group consisting of trifluoromethyl and ##STR2## in which R.sup.5 is selected from the group consisting of C.sub.1 -C.sub.3 alkyl, phenyl, and phenyl substituted with one or more members selected from the group consisting of halogen and trifluoromethyl. In a typical application, the 4-phenyl-1,2,3-thiadiazole is included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering a single application of the herbicide effective over a longer period of time.
除草活性巯基氨基甲酸酯与具有以下结构式的某些4-苯基-1,2,3-噻二唑结合使用:其中R.sup.4从三氟甲基和##STR2##组成的群体中选择;其中R.sup.5从C.sub.1-C.sub.3烷基、苯基和苯基中选择,其被来自卤素和三氟甲基组成的群体中的一个或多个成员取代。在典型应用中,4-苯基-1,2,3-噻二唑的含量足以减少巯基氨基甲酸酯在土壤中的降解速率。因此,巯基氨基甲酸酯的除草效果得到增强和延长,使得除草剂的单次施用在较长时间内有效。
