Well, is not some toxic chemical, so I can spray it daily, from my POV (if the plants are not damaged). I already took off all the diseased leaves (some plants reduced to almost stick stage) and gave them a chemical spray 2 days ago, but yesterday rain hit again. The mornings are cooler, and EVERYTHING is covered with water, like a heavy fog.
Will spray the entire garden, at least to prevent the spread to tomatillos, and to prevent anything to pepper.
ahhh, Just saw this peroxide page, looks like im going to run to the store, put a cup in a 2 gallon wattering can, and mix up a double batch to spray on the leaves.. See if it helps..
