Is this stuff of any real use? Are there drawbacks?
I tried it on my pepper seedlings to prevent every year pepper powdery mildew with no visible effect. Diluted milk works much better, though creates big mess when applied indoors.

Thanks - I was wondering in particular if it might be effective against botrytis on strawberries
I have used it. Most obvious success is it does a good job of keeping various leaf rots off basil. Actually very good at that. I did not notice as spectacular results elsewhere.
