AGENT FOR REDUCING CHEMICAL INJURY AND HERBICIDE WITH CHEMICAL INJURY REDUCED

PURPOSE:An agent for reducing chemical injury that contains, as an active ingredient, 1,2-benzoisothiazole-3(2H)-one-1,1-dioxide, thus showing high chemical injury reduction in a specific haloacetanilide herbicide, and the titled herbicide containing the same. CONSTITUTION:The objective agent contains, as active ingredients, 1,2-benzo- thiazol-3(2H)-one-1,1-dioxide which shows an effect of controlling rice blast or a compound of formula I (R is lower alkyl, lower alkenyl), or its salt which is known as an agent for controlling rice blast. These chemicals are used as an agent for reducing chemical injury caused by a haloacetanilide of formula II(R1, R2 are lower alkyl; R3 is 1-4C alkyl; A is methylene chain or ethylene chain or ethylene chain substituted with 1-2 methyl groups), which is known as a herbicide, and applied to a wide range of crops such as paddy-rice plant or corn to which the compond of formula II has been or will be applied. Further, the above active ingredient may be combined with the compound of formula IIto give a herbicide with chemical injury reduced.
