Abstract: Efficacy of three herbicides of "Bailongtong", "Kuoer" and "Chushabao" in peanut fields were contrasted. The results showed that "Bailongtong" had the best control effect with the longest effective duration, and the yield of peanut pod was similar to the manual weeding; "Kuoer" and "Chushabao" had poorer control effect, and the pod yield had a significant difference compared with the manual weeding. In production, the herbicide "Bailongtong" could be selected to control weeds in peanut field.
