Sounds like powdery mildew... common w/ lots of rain.

Short answer- potassium bicarbonate or if that's hard to find, baking soda.
Kills of fungi quite handily.
From Howard's lists:
Potassium Bicarbonate Fungicide
Mix 4 teaspoons (about 1 rounded tablespoon) of potassium bicarbonate into one gallon of water. Spray lightly on foliage of plants afflicted with black spot, powdery mildew, brown patch and other fungal diseases. Potassium bicarbonate is a good substitute for baking soda. There are commercial EPA registered as well as generic products available. |
