Mineral Fungicide for Powdery Mildew Active ingredient is potassium bicarbonate, which is a contact fungicide, so direct contact with the fungus organism is required for control. Works by disrupting the potassium ion balance in the fungus cell, causing cell walls to collapse. Use for powdery mildew on fruits, vegetables, lawns, herbs, ornamentals, and roses. Apply 2 tsp/gallon water; thoroughly cover foliage.
