How often can you use baking soda with water for powdery mildew? I use 2 tbl per gallon of water. I want to try to stay ahead of the spread. I already have some but its not all over the patch yet. any help.. ?

I had what I thought was great success with seaweed emulsion keeping PM to a minimum in years past. I alternated with Daconil. This year I've used Compass in the rotation, and no PM yet! The Compass has stopped the PM spread on an old lilac I use for test purposes.
Hope this helps,

i use Remedy. It's baking soda basically. Used it every 2 wks. at 1tbl / gallon. No problems w/PM at all.
