60%氟吗·锰锌防治黄瓜霜霉病药效试验

Control Effect Experiment on 60% Flumorph-Mn-Zn for Cucumber Downy Mildew

使用60％氟吗·锰锌防冶黄瓜霜霉病，每667m^2用80～120g进行喷雾，防效达77．19～92．67％，优于代森锰锌。大田上使用建议在黄瓜发病初期施药，每隔7～10d施一次，连续使用2～3次，每次施药量100～120g／667m^2。

Abstract： The results of field experiments on three agricultural chemicals show that spraying 80120g over each Mu （667m^2）, the effect of applying 6096 flumorph-Mn-Zn to control the cucumber downy mildew reaches 77.1992.67%, which excels that of Mancozeb. For field application, we recommend it at the early stage of the downy mildew, applying every 710 days for 23 times continuously and with 100120g/Mu each time.
