Powdery Mildew on Watermelon
Powdery mildew is a common disease on watermelon during moderately dry weather in South Carolina and the southeastern United States. Powdery mildew develops quickly on non-treated watermelon leaves. Several powdery mildew-specific fungicides help manage this disease, if they are applied when powdery mildew is seen.
