PURPOSE:To provide the title composition capable of selectively, significantly reducing the chemical injuries on barley, wheat, etc., and controlling a wide range of weeds, comprising as active ingredients a dispymidinyloxybenzoic acid derivative and 2,4-D or MCP. CONSTITUTION:The objective composition comprising as active ingradients (A) a compound of the fomula [R is H, alkali metal, alkaline earth metal, ammonium ion, ogranoammonium ion, CH2OCOC4H9-t or CH(CH3)COOC2H5] and (B) a compound selected from 2,4-dichlorophenoxyacetic acid (2,4-D), 2- methyl-4-chlorophenoxyacetic acid (MCP), their salts and their esters at a level of pref. 2-50 pts.wt. (for 2,4-D) or 4-100 pts.wt. (for MCP) per pt.wt. of the component A. The composition has outstanding herbicidal effects on both annual and perennial weeds. |
