Zusammenfassung:PURPOSE:To obtain the titled herbicide by compounding a thiolcarbamate herbicide with an amino acid (derivative) having a carboxyl group and an amino group, guanidyl group or aminocarbonyl group interposing >=2 C atoms therebetween. CONSTITUTION:The titled herbicide can be produced by compounding a thiolcarbamate herbicide (especially S-ethyl-hexahydro-1H-azepine-1-carbothioate) with 0.1-100wt% amino acid or its derivative. The amino acid used above is the one having a carboxyl group and an amino group, guanidyl group or aminocarboxyl group interposing >=2 C atoms between the carboxyl group, such as aspartic acid, trans-40-aminocyclohexanecarboxylic acid, p- aminomethylbenzoic acid, etc. The herbicide retains the herbicidal effect of the base herbicidal component and the fish toxicity suppressing effect can be maintained without loss even after scattering in paddy field.
