Three steps for Powdery mildew management
Components of a good PM management program:
1. Choose PM-tolerant or -resistant hybrids whenever possible to maximize host plant resistance against this disease.
2. Scout for PM beginning mid-summer on the upper and lower leaf surfaces throughout the field and leaf canopy. If even a few colonies are found, treatment should begin immediately and continue until harvest.
3. Know the Fungicide Resistance Action Code (FRAC) or mode of action (MOA) number (found on the label) for each fungicide used on your farm and how to rotate it.

Plant Pathologists at Land Grant Universities conduct fungicide efficacy trials on cucurbits to determine spray programs to recommend. Results of these trials are published in Plant Disease Management Reports.
Michigan Cucurbit update | July 26, 2023
Reports of virus symptoms in squash were received this week. Cucurbit downy mildew disease on pickling cucumber plants in a commercial production field were verified by the MSU vegetable pathology lab. Look for weekly spore trap updates and current downy mildew news on the Hausbeck Lab Downy Mildew News website.
Cucurbit downy mildew in Michigan
The first symptoms of cucurbit downy mildew disease on pickling cucumber plants in a commercial production field have been verifiedby qPCR in the Saginaw County lab on July 19, 2023. The statewide spore trapping network to detect downy mildew spores in the air has had positives in multiple counties.
