At first sign of disease, use 2 Tbsp per gallon of water. For best results, repeat at 1-2 week intervals until conditions are no longer favorable for disease development. Spray more often during rainy weather or during periods of high relative humidity.

Grower’s Tip:
This organic fungicide kills both mold and mildew spores on contact by causing an immediate dehydration of the spores and destruction of the cell walls. Many of the deceased spores will slough off or be washed away with the next rain or watering.
