PURPOSE:A herbicide composition obtained by dissolving a specific herbicide and a specified surface active agent in an amount effective for raising its herbicidal activity in water, etc. to give a highly concentrated solution, blending the solution with a specific amount of a specified quaternary ammonium salt so that the stability of the solution is improved. CONSTITUTION:(A) 1pt.wt. compound shown by the formula I or its salt (herbicide ), ( B ) 0.1-20pts.wt. compound shown by the formula II ( R<1> is long-chain alkyl; R<2> is long-chain alkyl, or lower alkyl; R<3>, and R<4> are lower alkyl; X is halogen), and (C) one or more surface active agents selected from polyoxyalkylene-long-chain alkylamine, polyoxyalkylene-long-chain alkyl ether, polyoxyalkylene-long-chain alkyl aryl ether, polyoxyalkylene-fatty acid ester, polyoxyalkylene-polyol fatty acid ester, and oxyethylene oxypropylene block polymer in a conventional amount effective for raising the herbicidal activity of the component A, are dissolved in water or water containing an organic solvent compatible with water, to give a stabilized herbicidal composition in the form of a highly concentrated solution. |
