PURPOSE:A herbicide composition that contains, as active ingredients, a combination of a 4-substituted-pyridine-3-carboxamide derivative with a known compound with herbicidal activity, thus enabling perfect control against all kinds of weeds by only one application with extremely reduced chemical injury and low toxicity to man and animals. CONSTITUTION:The objective composition contains, as active ingredients, a combination of a compound of the formula (R1 is alkyl, alkenyl, alkinyl, aralkyl, aryl; R2, R3 are alkyl, cycloalkyl aralkyl; n is 0, 1; R4 is H, in case of n=0, or H, halogen, alkyl in case of n=1; A is H, halogen, CN, NO2, NH2 alkyl; Z is N, N 0) with another compound selected from 16 compounds including i) 3-isopropyl-2,1,3-benzothiazinone-(4)-2,2-dioxide, ii) 3-(3,4-dichlorophenyl)-1- methoxy-1-methylurea, iii) 2-[4-(3,5-dichloro-2-pyridyloxy)phenoxy]propionic acid and others, at a weight ratio of 1:(0.2-5). |
