Powdery Mildew? Downy Mildew? Early blight? – Biogrow Copper Soap

Copper Soap 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. It is suited for use in domestic circumstances, both indoors and outdoors.

The National Organics Standards Board of the USA allows fixed copper to be used in organic crop production for controlling plant diseases. It controls diseases on a wide range of fruit, vegetable and ornamental plants. As with most fungicides it acts to protect plants from infection. Therefore, it is important to have the Copper Soap on the leaf, flower or fruit before the pathogen is able to cause an infection.

It 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.

Application rates: 500ml – 1500ml per 100L water, use the higher dosage under high infection periods.
