Powdery mildew is a fungal disease.

Dock roots

"Experiments with the roots of the common dock weed as a control for mildew have been carried out in Switzerland. Mature dock roots were pureed and mixed with water at the rate of 15gms per litre. Left to soak for an hour they were then sprayed on cucumbers and apples.

Results suggest that the solution is as effective against powdery mildew as many modern fungicides. So now you know what to do with your docks- if you are strong enough to pull them out of the ground. "
