Downy Mildew of Cucumber Detected in South Georgia

By Bhabesh Dutta, Downy mildew of cucumber has been detected from the Brooks County, GA. These observations indicate that inoculum of downy mildew is currently in southern GA counties  and under favorable conditions  potential disease outbreak in other cucurbits  can occur. I would suggest our cucurbit growers to look for the downy mildew symptoms in their fields and start applying protective spray of below stated fungicides.

 

 

 

Watermelon: Rotation (foliar application)  with  Orondis ultra (provide protection against both Downy and P. capsici);

Elumin+Bravo/Manzate;

Ranman+Bravo/Manzate;

Previcur flex+Bravo/Manzate

 

Please do not use Bravo after fruit set.

 

Other cucurbits: Orondis opti;

Elumin+Bravo;

Ranman+Bravo

Previcur flex+Bravo

 

If Orondis was used as a soil application, please do not use it as foliar (use restriction according to label).
