Mode of action:
Bi-carb Old Fashioned Fungicide contains microencapsulated potassium bicarbonate as the active ingredient. Bi-carb Old Fashioned Fungicide is a contact fungicide, requiring direct contact with the fungus organism for control. Bi-carb Old Fashioned Fungicide disrupts the potassium ion balance in the fungus cell, causing the cell walls to collapse.
For residential use. Apply with a hand-held sprayer. Make sure to spray foliage thoroughly, as contact with the disease organisms is essential for control. Use a non-acidifying spreader/sticker such as Monterey – Nature’s Own Spray Helper. This product can also be used with a non-phytotoxic crop oil.
