This is one of the better PM articles I have seen on the net. One correction is that baking soda does not stop powdery mildew, it only helps to prevent it. You may spray it on and think your PM is gone, but if you come back in a couple of hours your PM has returned.
Pristine is a BASF product that actually eliminates PM. Some form of it might be available to homeowners. Of the softer chemistries, Circadian Sunrise is the only one I've seen that consistently stops PM cold. The problem with that product is that the smallest unit presently sold is a 2.5 lb concentrate, which is far more product than most homeowner will use in their gardens over the course of a year or more.
