[Results] The result showed that the herbicide could effectively control the weeds in corn field. The optimal treatment stage of 2,4-D butylate · bromoxynil octanoate, nicosulfuron 30% OD is at 3-5 leaves stage of corn and 2-4 leaves stage of grass weeds or 2-5 cm high of broadleaf weeds. The optimum dosage is 420-630 g a.i./ha. [Conclusions] 2,4-D Butylate. bromoxynil octanoate · nicosulfuron 30% OD showed good efficacy on grass weeds and broadleaf weeds in corn field, and safe to corn.
