Substituted phenyl (thiono)carbamates, herbicidal compositions containing the same as active ingredient and method of controlling weeds

摘要

There are provided novel substituted phenyl (thiono)carbamates capable of effectively controlling broad-leaved annual weeds and annual weeds belonging to the families Gramineae and Cyperaceae such as wild Echinochloa species, monochoria, toothcup and umbrella plant, herbicidal compositions containing these (thiono)carbamates as active ingredient and a method of controlling weeds using these (thiono)carbamates. The (thiono)carbamates are substantially nonphytotoxic to useful crop plants such as the paddy rice plant.
