Herbicide composition containing dicamba and clodinafop-propargyl and application thereof

The invention provides a herbicide composition. Active ingredients in the composition comprise dicamba and clodinafop-propargyl in a ratio of (1:1)-(40:1). The herbicide composition can be prepared into wettable powder and water-dispersible granules according to the known methods. The herbicide composition has the following advantages: relative to the single agent, on the premise of expanding the weed-controlling spectrum, the herbicide composition delays generation of weed resistance, improves the pesticide effect, has low residues, is safe to wheat and afterreap crops and can control most monocotyledon and dicotyledon weeds in wheat fields once.
