E-mail Print PDF


Below are links to regional and / or state control recommendations for cucurbit downy mildew.  

 ***Please contact your local extension office or your State Coordinator for more information regarding the control and prevention of cucurbit downy mildew.***

Downy mildew is a very destructive disease and progresses rapidly under favorable conditions. Fungicides are much more effective when applied well before symptoms are visible. Initiating a downy mildew control program after symptoms have been detected is much more likely to fail.
