Abstract: To select safe, high efficient and low cost herbicide for rapeseed in sprouting stage, the control effect of different herbicides and their application amount on weed in rapeseed field were studied. The results showed that all the applied herbicides were safe to rapeseed plants in this experiment, and the control efficiency was above 94% to gramineous weeds and broadleaf weeds in the field, the income increase was above 4340 yuan/hm2. Among all the herbicides application, soil surface spraying after planting with 50% different pine·acetochlor 1200 mL/hm2 mixed with water 1125 kg/hm2 had the best weeding and yield-increasing effect.
