PURPOSE:To obtain a herbicide composition for upland farming, showing synergistic effects, exhibiting high effects with a small amount of herbicide free from phytotoxicity, containing a 3-substituted phenylpyrazole derivative and a sulfonylurea-based compound. CONSTITUTION:A herbicide composition for upland farming containing a compound shown by the formula (R is lower alkyl; X is halogen) and a sulfonylurea- based compound (e.g. chlorsulfuron) in a weight ratio of 1:0.2-2 is produced and 1-20g calculated as active ingredient based on 1ha of the herbicide composition is applied to a plowed field of wheat to exterminate weeds. Cleavers, white- bird's-eye, Stellaria media cry., Veronica persica Poir, violet, INUKAMITSURE, etc., which have been difficult to control can be weeded and treatment is effectively carried out at initial stage of emergence and growing period of wheat and weeds. |
