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.
