  • Echinochloa crusgalli（L.） Beauv was pot cultured in greenhouse and treated with 36 novel pyribenzoxim compounds. The activities and herbicidal activities of these 36 compounds against E.crusgalli were determined. The result showed that the 36 compounds at a concentration of 50 mg·L-1 had fresh weight-based inhibition rates of 87.31%～93.18% against E.crusgalli（L.） Beauv.. The toxicity tests showed that the IC50 values for the 36 compounds against E.crusgalli（L.） Beauv. were ranged from 1.123 7 mg·L-1 to 8.734 1 mg·L-1. These compounds had good herbicidal activity against E.crusgalli（L.） Beauv., have broad application prospects and can be further developed.

Abstract: Echinochloa crusgalli（L.） Beauv was pot cultured in greenhouse and treated with 36 novel pyribenzoxim compounds. The activities and herbicidal activities of these 36 compounds against E.crusgalli were determined. The result showed that the 36 compounds at a concentration of 50 mg·L-1 had fresh weight-based inhibition rates of 87.31%～93.18% against E.crusgalli（L.） Beauv.. The toxicity tests showed that the IC50 values for the 36 compounds against E.crusgalli（L.） Beauv. were ranged from 1.123 7 mg·L-1 to 8.734 1 mg·L-1. These compounds had good herbicidal activity against E.crusgalli（L.） Beauv., have broad application prospects and can be further developed.
