Abstract: To screen for safe and effective soil-applied herbicides to prevent and control of buffalobur, pot experiments were conducted to evaluate the control effect of 5 preemergent herbicides against buffalobur, and greenhouse bioassay were further conducted for the herbicides with better control effects. The results showed that the toxicity of acetochlor was the highest, while that of pendimethalin was the lowest, the ED90 were 41 . 43 and 748. 56g a. i. /hm2, respectively. The order of toxicity was acetochlor > clomazone > alachlor > s-metolachlor > pendimethalin. Based on consideration of herbicidal activity and recommended rate, the 5 herbicides could be used to controlbuffalobur at lower dose than recommended.
