Baking Soda in a different form. Not to be confused with the more common sodium biocarbonate. Used for the control of powdery mildew on all crops. Mix 5-10 grammes in 1 litre of water with wetting agent. Stir until dissolved. Spray all the leaves until run off. It is only a contact fungicide so make sure you hit all leaves. Don't spray in full sun or rain.
