PURPOSE:To obtain a herbicide composition capable of selectively controlling weeds in soybean fields, etc., without phytotoxicity, by using a specific 2- substituted-4,5,6,7-tetrahydro-1H-isoindol-1,3(2H)-dione and a dinitroaniline derivative. CONSTITUTION:A compound shown by formula I is blended with a compound shown by formula II (A is CF3 or CH; B is H, NH2 or CH3; R1 is 1-5C alkyl; R2 is 1-4C alkyl) as active ingredients in the ratio of usually 1 pt.wt. compound shown by formula I and 2-100 pts.wt., preferably 5-50 pts. wt. specific shown by formula II to give a herbicide composition which has synergistically increased herbicidal power, enlarges herbicidal spectrum and can destroy a wide range of weeds especially in soybean fields, cotton fields, wheat fields and harley fields with a small amount without exerting phytotoxicity to crops such as soybeans, cotton, wheat and barley. |
