PYRAZOLESULFONYLUREA COMPOUND AND METHOD FOR CONTROLLING ALS-RESISTANT WEED USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a controller against an ALS inhibitory herbicide-resistant weeds. SOLUTION: The subject method for controlling ALS-resistant weeds comprises using one or more kinds selected from a pyrazolesulfonylurea compound represented by formula (1) [R1is a 1-6C alkyl group which may be substituted with a halogen atom, or the like; R2is a 1-4C alkyl group which may be substituted with a 1-4C alkoxy, or the like] and its salt acceptable as an agrochemical. When R2is methyl group in formula (1), the compound of formula (1) is a compound in which R1is a 1-6C alkyl group substituted with a halogen atom, a cyano group, or the like, or its salt.
