HERBICIDAL COMPOSITION CONTAINING 3-PHENOXY-4-PYRIDAZINOL COMPOUND

摘要

PROBLEM TO BE SOLVED: To expand a herbicidal spectrum of a 3-phenoxy-4-pyridazinol derivative, and to provide a means capable of preventing and eliminating principal weeds in a smaller amount than ever. SOLUTION: A herbicidal composition contains a compound expressed by general formula (I) (R1is H, a halogen, an alkyl or the like; R2is H, a halogen, an alkyl or the like; R3, R4, R5, R6, and R7are each H, a halogen, an alkyl which may be substituted, an alkenyl which may be substituted, an alkynyl, a cycloalkyl which may be substituted or the like, or two of R3, R4, R5, R6, and R7adjacent to each other may combine with each other together with carbons bonding thereto and form a ring which may be substituted; and m and n are each 0 or 1), its salt, its esterified derivative, and 3-(4-chloro-5-cyclopentyloxy-2-fluorophenyl)-5-isopropylidene-1,3-oxazolidine-2,4-dione as active ingredients.
