curcurbit08

Below is a recommended spray regime from Dr.  Bhabesh Dutta, Extension Vegetable Plant Pathologist;

These observations indicate that inoculum of downy mildew is currently in GA and under favorable conditions (cool and wet conditions) potential disease outbreak in cucurbit 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+Bravo/Manzate;

Ranman+Bravo/Manzate;

Previcur flex+Bravo/manzate

Please do not use bravo after fruit set.

Other cucurbits: 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).

If Orondis was not used as a soil application, foliar application can be done for controlling downy mildew.
