SAFENERS FOR HERBICIDES, HERBICIDAL COMPOSITIONS WITH REDUCED CHEMICAL DAMAGE AND SAFENING METHOD USING SAME

摘要

Disclosed are safeners for herbicides that comprise as the active ingredient isothiazole derivatives or salts thereof that are very suitable for reducing chemical damage to crops without reducing herbicidal effects, herbicidal compositions with reduced chemical damage that have said safeners and herbicides as active ingredients, and a safening method using same. The herbicide safeners comprise 3,4-dihalogenoisothiazole derivatives represented by general formula [I] [in the formula, X1 and X2 represent halogen atoms, and R represents a C1-C6 alkyl group, C2-C6 alkenyl group, C2-C6 alkynyl group, C3-C6 cycloalkyl group, C1-C6 haloalkyl group, phenyl group or a 5- to 10-membered heterocyclic group that comprises at least on oxygen atom, sulfur atom or nitrogen atom.] or salts thereof as the active ingredient.
