PURPOSE:A herbicidal agent that contains a combination of N-penyltetrahydro phtahlic imide derivative with a phonoxypropionic acid derivative, thus increas ing its herbicidal effect synergetically and being applied to crop fields in low doses. CONSTITUTION:The objective herbicidal agent contains, as active ingredients, an N-phenyltetrahydrophthalic imide derivative of formula I (R is lower alkyl, cycloalkyl) and a phenoxypropionic acid derivative of formula II (X is H, Cl; Y is Cl, trifluoromethyl; Z is lower alkyl), preferably at a weight ratio of 1:(0.1-50, preferably 0.2-20). |
