Hi, I was hoping for some advice from all you experienced growers... I have sprayed (fixed copper) for botrytis once this season, but am having some additional foliage dieback. I've trimmed off all the dead leaves and buds. Now I'm wondering if it's too late to spray again, now that the buds are getting ready to open.

In other words, is there a time (in the bud/flower opening sequence) beyond which it's better not to spray?

Thanks for any help.
