Due to CFIA regulations we cannot ship plants outside of Canada and cannot ship fruit trees or grape vines to BC.

Try Lee Reich's simple recipe for powdery mildew control in grapes or gooseberries. Spray plants with the following:
4 litres (1 gallon) of water
1 tablespoon sodium bicarbonate (baking soda)
1 tablespoon canola oil
Repeated applications may be needed, especially in rainy weather.
