HERBICIDE COMPOSITION

PROBLEM TO BE SOLVED: To obtain a herbicide composition for paddy field weeds that enables more reduction of herbicide consumption, enlargement of herbicidal spectrum, development of appropriate control effects and more labor saving owing to synergistic effects of a combination of three specific herbicides. SOLUTION: This herbicide composition for paddy field weeds is obtained by combination of a tetrazolinione compound of formula I (X and Y are each H, a halogen, an alkyl; R is an alkyl; R is a cycloalkyl), a sulfonyl urea compound of formula II (T is formula III, etc.), and oxyacetoamide compound of formula IV (W is formula V, etc.; R is methyl when W is formula V; Z is H). It is preferable for this composition to contain approximately 0.02 to approximately 1 pt.wt. of the compound of formula II, and approximately 0.002 to approximately 5 pts.wt. of the compound of formula IV, per 1 pt.wt. of the compound of formula I. To this composition, 1-(4,6-dimethoxypiperidin-2-yl)-3-[1- methyl-4-(2-methyl-2H-tetrazol-5-yl)-pyrazol-5-yl sulfonyl urea, etc., may be added.
