Growers should scout their fields twice per week and protect their crops. The continuos wet weather we have been experiencing will favor the disease. The forecast for cucurbit downy mildew risk in NC continues to be high.

If you think you have cucurbit downy mildew in your cucurbits please contact your local Extension Agent and send photos and/or physical samples to the Plant Disease and Insect Clinic. If cucurbit downy mildew is confirmed in your samples by an expert, please make sure a report is sent to the Cucurbit downy mildew IPM pipe website.
