The invention discloses a weedicide composition for preventing and removing weeds in cornfield, particularly a weedicide for preventing and removing grassy weeds and broadleaf weeds in cornfield, which is a binary weedicide mixture composed of topramezone and eluthiacet-methyl as active components. The weight ratio of topramezone to eluthiacet-methyl in the composition is (16:1)-(1:8), preferably(8:1)-(1:2). The weedicide composition can be prepared into water-dispersion granulas, wettable powder, suspending agents, dispersible oil suspending agents, missible oil and microemulsion. The weedicide composition is used for preventing and removing weeds in cornfield, contains reasonable components, is superior to the activities of each single component applied independently in the aspect of prevention effect, widens the weed control spectrum, lowers the cost for preventing and removing weeds, slow down the generation of weed resistance, is safe for crops and conforms to the safety requirements for pesticide preparations. |
