Dorothy,
The main problem with spraying grapes during bloom is the
possibility of knocking off the blooms and thus reducing the fruit set. If
the pressure on your spray rig is not too strong, you should be okay. If
you have any cytokinin sources in your tea, I would think you should get a nice
benefit to fruit development. Having some humisolve tm7 and soluble kelp
in the tea will really green up the leaves on your grapes.

Laura, Dan, Elaine, et al--
I have read on one of
these lists that it is not a good practice to spray CT at bloom because it
has some sort of adverse effect on the fruit set.
Does anyone
have details on this or an explanation as to what that would be so?
My vines are looking pretty good this year. I've
been spraying about 1x per week. My recipes have been mostly
fungal, using a combination of Alaska Humus and home grown
vermicompost. Occasionally I see a very few leaves with
some black rot type spots.
The Chambourcin, which has a reputation for
being very susceptible to black rot, looks excellent, no spots there at
all.
And thanks to Laura on the organic molasses source--got
some.
Dorothy
