The results showed that the control effect of 68% Metalaxyl-M·Mancozeb WDG at the dose of 1 133-1 360 mg/kg against D. officinale blight was over 78.4% at 14 d post spraying, which was equivalent to that of control agent 72% Cymoxanil·Mancozeb WP(1 200 mg/kg) and 80% Mancozeb WP(1 143 mg/kg).Therefore, 68% Metalaxyl-M·Mancozeb WDG sprayed at the dose of 1 133-1 360 mg/kg could effectively control the damage of D. officinale blight.展开更多
