The present invention is based on the general formula () (In the formula, R 1 and R 2 represent lower alkyl groups,
R 3 represents an alkyl group having 1 to 4 carbon atoms, and A represents an unsubstituted methylene chain, an unsubstituted ethylene chain, or an ethylene chain substituted with one or two methyl groups. This invention relates to a drug-toxicity reducer for acetanilide. More specifically, 1,2-benziisothiazol-3(2H)-one-1,1-
Dioxide or its salt, or general formula (I) (wherein R represents a lower alkyl group or a lower alkenyl group). Herbicides use selectivity to control harmful weeds in areas where useful crops are cultivated by chemical means, but there are few that show inherent selectivity between crops and weeds. In many cases, selectivity is achieved by utilizing differences in the growth stages of crops and weeds, differences in the position of seeds of crops and weeds in the soil, and differences in attachment on the leaf surface. Therefore, depending on the type of soil, temperature, weather such as rainfall, dosage, etc., chemical damage, which is an undesirable side effect, often occurs. This applies to many herbicides, such as triazine, urea, carbamate, phenoxy, phenol, and acetanilide herbicides. For this reason, many studies have been conducted in the past on phytotoxicity reducing agents for these herbicides. N,N-diallyl-2,2-dichloroacetamide [Weed Science 21 (4), 292-
295 (1973)] and alachlor (N-methoxymethyl-2,6-diethyl-α-chloroacetanilide), weed science 22
(1), 86-90 (1974)) are known. Haloacetanilide represented by the general formula (), which is already known to be a useful compound as a herbicide (Japanese Patent Publication No. 48-37820, Japanese Patent Publication No. 49-54527), is also a compound useful as a herbicide in the same way as various other herbicides. May cause drug damage. The present inventors searched for a phytotoxicity reducer for haloacetanilide herbicides represented by the general formula (),
1,2-benzisothiazol-3(2H)-one-1,1-dioxide or a salt thereof, or
It has been found that the compound represented by the general formula (I), which is known as a rice blast control agent (Japanese Patent Publication No. 38080/1983), exhibits a remarkable alleviation effect. Crops that exhibit the phytotoxicity reducing effect of this compound include paddy rice, crops to which the herbicide represented by the general formula () can be applied, such as corn, wheat, barley, beer barley, upland rice, soybeans, cotton, peanuts, sugar beet, etc. It is wide-ranging. 1,2-Benzisothiazol-3(2H)-one-1,1- used as a drug harm reducer in the present invention
Dioxide, its salts, and the compound represented by the general formula (I) are known to have a rice blast control effect, but their herbicidal activity and herbicidal damage reducing effect are not known. Compounds that can be used as the drug-toxicity reducing agent of the present invention include those shown in the following table.

That is, soybean cultivation areas can be treated with a herbicide before, at the same time, or after the soybean is sown and sprayed with a haloacetanilide herbicide, and the soybean can be coated with a herbicide. Alternatively, the drug-toxicity reducing agent can be homogeneously mixed with a suitable carrier, an active agent, a dispersant, and a binder added thereto, and then granulated for use. The drug harm reducer of the present invention can also be used in other forms such as emulsions, wettable powders, powders, liquids, or flowables. The amount of the phytotoxicity reducer used is 0.01 to 5 parts by weight per 1 part by weight of the haloacetanilide, but the optimum amount is determined on a case-by-case basis depending on the type of haloacetanilide used and the target crop. It is said that the action of haloacetanilide herbicides lies in the inhibition of protein biosynthesis, but in the case of paddy rice, for example, symptoms such as reduced plant height, inhibition of new leaf extraction, and shrunken leaves are observed. In severe cases, it can greatly affect the yield. In this case, if the phytotoxicity reducing agent of the present invention is applied at the same time, the above phytotoxicity symptoms will be significantly reduced without any effect on the herbicidal effect, or no phytotoxicity symptoms will be observed at all, resulting in good results on the yield of paddy rice. . The drug damage reducer of the present invention is effective against the haloacetanilide herbicide represented by the above general formula (). Examples of the haloacetanilide represented by the general formula () include those shown in the following table.

21 parts, sodium dodecylbenzenesulfonate 1
1 part of polyoxyethylene alkyl allyl ether, and 2 parts of sodium lignin sulfonate are mixed, then an appropriate amount of water is added and kneaded, and the mixture is granulated using a granulator in the usual manner to form a granule of 100 parts. get the part. Example 2 Herbicide granules that reduce chemical damage After mixing 2 parts of Compound C, 1 part of Compound 6, 73 parts of bentonite, 21 parts of talc, 2 parts of sodium ligninsulfonate, and 1 part of sodium dodecylbenzenesulfonate, an appropriate amount of water was added. Add and knead and granulate using a granulator in the usual manner to form granules.
Get 100 copies. Example 3 Powder of phytotoxicity reducer 0.5 part of Compound 3 and 99.5 parts of a mixture of diatomaceous earth and clay were mixed and ground to obtain 100 parts of a powder. Example 4 Wettable powder for a herbicide that reduces chemical damage 50 parts of Compound D, 2 parts of Compound 2, 10 parts of white carbon, 33 parts of diatomaceous earth, 3 parts of sodium ligninsulfonate, and 2 parts of sodium dodecylbenzenesulfonate are mixed and ground, and mixed with water. Obtain 100 parts of Japanese medicine. Example 5 Herbicide emulsion with reduced chemical damage 40 parts of Compound A, 2 parts of Compound 1, 48 parts of orthoxylene and 10 parts of fatty alcohol polyglycol ether were mixed and dissolved to obtain 100 parts of an emulsion. Test Example 1 Test on the effect of reducing phytotoxicity by seed coating Five doses of Compound 3 were applied to each seed of corn (variety: Golden Cross Bantam), wheat (variety: Norin No. 27), and soybean (variety: Fukumusume) in a greenhouse.
% of powder at a ratio of 10g to 100g of seeds, sown in pots filled with sandy soil, treated with Compound A or Compound D at a prescribed dose the next day, and conducted a sampling survey on the 40th day after treatment. Table 1 shows the results of comparing the growth amount with the case where seeds were coated without a phytotoxicity reducer.

When the leaves reached the 2.5 leaf stage, 50g or 100g of Compound 6 prepared in 5% granules was applied per box.
9/2000 filled with sandy soil in advance after hours
Three paddy rice plants were planted in Wagner pots with the soil still attached, and two plants per pot were planted at a depth of 3 cm. On the 5th day after transplantation, the plants were treated with a predetermined dose of granules of Compound B or Compound C, grown in a greenhouse, and observed and investigated on the 10th and 20th days after the treatment. Table 2 shows the results. The display category for the degree of chemical damage to paddy rice is "severe damage"
There were six levels: "major harm,""moderateharm,""slightharm,""slightharm," and "harmless."
