Bi Carb Fungicide is a organic fungicide for use in controlling powdery mildew on roses, vegetables, grapes, fruit trees and ornamentals. This fungicide contains microencapsulated potassium bicarbonate as the active ingredient. It is a contact fungicide, so direct contact with the fungus organism is required for control. It works by disrupting the potassium ion balance in the fungus cell, causing the cell walls to collapse.
Bi Carb Fungicide Instructions
Mix 4 teaspoons in 2 gallons of water to thoroughly cover foliage. Fill the spray tank 1/2 full with the required amount of water; add Bi Carb Fungicide slowly; then, continue filling with balance of water. Add the spreader/sticker and/or other products last. DO NOT allow mixture to stand. Use within 24 hours as it may lose its activity if left in the tank.
