The Liquid Copper concentrate provides excellent control of blights, leaf spots, rusts, mildews, scab, anthracnose and mold with as little as 1-1/2 teaspoons per gallon. University studies have shown copper fungicides to be one of the most effective ways to treat late blight in organic systems. A natural way to control disease, Liquid Copper fungicide is also ideal for indoor use. Certified organic growers should consult their certifier before using copper products.
