Herbicidally active thiolcarbamates are employed in combination with certain substituted carbamates having the formula
in which
R4 and R5 are each methyl,
R4 and R5 conjointly form C1-C4 alkylenedioxy,
R4 is -CF3 and R5 is hydrogen, or
R4 is -CH2Br and R5 is hydrogen.
In a typical application, the carbamate 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.
具有除草活性的硫代氨基甲酸乙酯可与某些取代的氨基甲酸酯结合使用,这些氨基甲酸酯的式中 R4 和 R5 分别为甲基,R4 和 R5 共同形成 C1-C4 亚烷基二氧基,R4 为-CF3,R5 为氢,或 R4 为-CH2Br,R5 为氢。 在典型的应用中,氨基甲酸酯的用量足以降低硫代氨基甲酸乙酯在土壤中的降解速度。 因此,硫代氨基甲酸乙酯的除草效果得到增强和延长,使除草剂的单次施用在更长的时间内有效。
