Powdery mildew

August is here and so is the powdery mildew on the monarda and the phlox is
getting ready to bloom, so I hate to see it. There was a "homemade" recipe
for a spray sent to the list, but I can't find where I saved it. In doing a
search online, I found a paper comparing different sprays on one cultivar of
phlox, and thought it might be of interest. Here's the URL:

WiltPruf gave the best results in this trial - interesting!

And if someone still has the baking soda/horticultural oil recipe, could you
send it out again?

Thanks, Barb in WI
