【Abstract】 [Aims] This study aims to clarify the control effect of mancozeb·benalaxyl-M 69% WG against potato late blight diseases, and provide the basis for security application in field. [Methods] According to guidelines for the field efficacy trials. [Results] The results showed that the control efficacy of mancozeb·benalaxyl-M 69% WG(1552.5 and1725 g a.i./ha) against potato late blight disease was over 86%, which was significantly higher than controls.Mancozeb·benalaxyl-M 69% WG(1552.5 and 1725 g a.i./ha) respectively gave 13.95 and 18.43% yield increase of potato. [Conclusions] Potato late blight disease could be effectively controlled by mancozeb·benalaxyl-M 69% WG.The recommended dose was 1552.5-1725 g a.i./ha in field.更多还原
