Abstract：In order to clarify the herbicides that are safe to common beans and have good control effect on common pre-emergence weeds，17 herbicides were screened by indoor pot experiment and field experiment．The results of pot experiment showed that pendimethalin，prometryn and S-metolachlor had good safety to common beans at seedling stage．The field experiment showed that 45% S-metolachlor microcapsule suspension 2 025-3 225 g · hm-2 had good control effect on weeds in the vegetable field 30 days after application．The total number of plants that had control effect was 77.52%-78.58%，and the fresh weight prevention effect was 88.21%-88.92%．It had good safety to common beans，and the yield of common beans increased by 11.61%-20.51%．It shows that 45% S-metolachlor CS can be used as a herbicide for pre-emergence weeds after common bean sowing，and has a good application prospect．
