Biogrow Copper Soap is a natural organic fungicide.  Provides preventative control of downy and powdery mildew, black spot, rust, botrytis rot and early and late blight.

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.

Biogrow 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 copper soap 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.


Use 10-20 ml per 1 liter


Additional Preventative measures that can be taken to help prevent plants from falling prey to molds later on in life:

  • Expose them to Trichoderma Fungus (a fungus that is beneficial to a plant when introduced into the root zone)
  • Apply a silicon plant supplement on a regular basis from a young age, right throughout the plants’ life cycle. Silicon strengthens plant cell wall, amongst other things and this will it harder for molds and mildew to take hold on the plant surfaces.
