This product is a patented, fixed copper fungicide, made by combining a soluble copper fertilizer with a naturally occurring fatty acid. The copper and the fatty acid combine to form a copper salt of the fatty acid, known technically as soap. The copper soap fungicide controls many common diseases using low concentrations of copper, down as low as 90 ppm. The net result is an excellent vegetable, fruit and ornamental fungicide. It decomposes to form soluble copper, and fatty acid, both of which can be used by microbes and plants.
The copper soap is suited for use in domestic circumstances, both indoors and outdoors. This product controls diseases of a wide range of plants, including many vegetable, fruit and ornamentals. As with most fungicides it acts to protect plants from infection. Therefore, it is important to have the coppersoap on the leaf, flower or fruit before the pathogen is able to cause an infection. This product will control fungal diseases such as : powdery mildew and downy mildew on vegetables and ornamentals, rust on ornamentals, late blight on potatoes and tomatoes, and Peronospora and downy mildew on grapes.
