The invention belongs to the field of weeding, and discloses a mixing
weed killer containing bentazone,
acifluorfen-
sodium and fenoxaprop-p-ethyl, and an application thereof. The mixing
weed killer adopts the bentazone, the
acifluorfen-
sodium and the fenoxaprop-p-ethyl as main effective components, wherein a
mass ratio of the bentazone to the
acifluorfen-
sodium to the fenoxaprop-p-ethyl is 0.1-80:0.1-80:0.1-80, the total
mass percentage of the three materials in the mixing
weed killer is 1-85%. The mixing weed killer provided by the present invention can be applicable for weeding in the soybean field after
seedling, specifically provides significant effects for prevention and
elimination of various grassy weeds and broadleaf weeds in the soybean field. Compared to the single weed killer, in the premise of improvement of the
efficacy, the weeding composition provided by the present invention delays the resistance generating of the weeds, and has wide weeding spectrum and long effectiveduration, and provides safeties for the soybean and the succeeding crops.
