The invention discloses a compound weeding composition. Effective components of the compound weeding composition include
dicamba, agroxone and pinoxaden, wherein a weight ratio of
dicamba to agroxone to pinoxaden is 0.5-5: 1-15: 1-30; besides, the compound weeding composition also contains a dispersing agent, an emulsifier, a
wetting agent, an antifreezing agent, a
thickening agent, a disintegrating agent, a binder, filler, a
solvent and other auxiliaries; the
dosage form of the compound weeding composition can be
wettable powder, suspending agent, water dispersing granules and
emulsion oil. The weeding effect of the compound weeding composition is significantly improved by comparing with that of single dosage, and the compound weeding composition can be applied to prevention and
elimination of broad-leaf
weed, nutgrass flatsedge and grassy
weed in wheat fields; thus the compound weeding composition can enlarge herbicide controlling spectrum, improve prevention effects, retard
weed resistance, reduce consumption of
dicamba, decrease using cost, and improve wheat safety.
