Was reading about "Actinovate" the other day, it is Streptomyces lydicus, and reported to be effective against botrytis.
B. subtilis is recommended for many things - the whole EM gang sounds really benign so I hope it does continue to work for you.
I get botrytis at some point in the greenhouse every year. It's the thing that brings them down at the end of season come what may. But it's terrible to have in a wet spring or cool summer when the plants are still setting fruit.
Always interested to hear of ways of controlling it, for the tough season that's just around the corner.
