PURPOSE:To obtain a herbicide showing extremely excellent synergistic effects on gramineous weeds and cyperaceous weeds, capable of reducing phytotoxicity to crops because of enabling of remarkable reduction in amount of herbicide, containing cinmethylin and bromobutide in a specific ratio. CONSTITUTION:A herbicide composition obtained by blending 1 pt.wt. cinmethylin shown by formula I with 1-20 pts.wt. bromobutide shown by formula II, surfactant, solid carrier, binder, etc. and made into granules by aggregation method or impregnation method or into a form such as wettable powder or paste. The herbicide has not only excellent effects on weeds in paddy fields such as Echinochloa oryzicola Vasing, Echinochloa crus-galli Beauv. var. praticola Ohwi., monochoria, water nutgrass, slender spikerush, etc., but also can reduce the amount of herbicide because of synergistic effects by blending. Treatment period of the herbicide is suitably prior to germination to early stage of growth. |
