摘要
In bioassays on cucumber (Cucumis sativus) inNewYork, Ohio, and South Carolina in 2015 and 2017, mandipropamid (Revus) and azoxystrobin (Quadris) failed to suppress downy mildew caused by Pseudoperonospora cubensis. Propamocarb (Previcur Flex), cymoxanil + famoxadone (Tanos), and fluopicolide (Presidio) were ineffective in one or two states in both years. Famoxadone, dimethomorph (Forum), cymoxanil (Curzate), and mancozeb (Manzate) were ineffective in one state one year. Oxathiapiprolin, cyazofamid (Ranman), and fluazinam (Omega) suppressed downy mildew in >= 80% of the bioassays.
