Cucurbit Downy Mildew Update – August 11, 2014

Cucurbit Downy Mildew has been identified in a cucumber field in Chatham-Kent, Ontario.  Levels were very low (< 1% of the field). The infection likely occurred within the past few days.  However, this does indicate that all area cucumber and melon fields are at a high risk of developing downy mildew at this time.

Continue to use a preventative fungicide program, rotating between the targeted downy mildew fungicides.  For more information on fungicide selection, see the Downy Mildew Report – July 11, 2014.
