Herbicide composition containing mesosulfuron

The invention relates to a herbicide composition, and especially relates to a herbicide composition for controlling weeds in wheat fields. The active components of the herbicide composition are halauxifen-methyl, bentazone, and mesosulfuron, the weight ratio of halauxifen-methyl: bentazone: mesosulfuron is (0.5-8): (47.5-760): (1-16), and active components account for 5 to 90% of the weight of the composition. The provided herbicide composition can control various weeds in wheat fields, the control effect is prominently enhanced; the using amount of effective components is little, the using cost is low, the safety of wheat and after-reap crops is guaranteed, and the herbicide composition is an ideal herbicide.
