Abstract
[aims] The paper aims to explore the action mode and control effect of lh-2010A against cucumber downy mildew.[Mothods] The floating leaf disc bioassay was adopted to determine the preventive and curative toxicity.[Results] lh-2010A has good preventive and curative toxicity with ec50values of 6.70 and 15.06 mg/L respectively,while ec50 of fluopicolide were 7.66 and 9.68 mg/L respectively.Cucumber downy mildew can be controlled well by spraying LH-2010A 25% SC once downy mildew occurs at the concentration of 375 g/ha.The control efficacy reached 98.29% at the 10th day after spraying.Disease can also be hold by praying LH-2010A twice with a 10 d internal,too,and the control efficacy were 97.74 and 83.59%.The dilution of LH-2010A 25% SC with the concentration of 1687.5,562.5,270,135,67.5 g/ha were all safe to cucumber seedlings.[Conclusions] lh-2010A can be applied to control cucumber downy mildew in practical production.
