Hi, Byron -- you probably have heard me tell this before -- about 9 years ago, Cornell had come out with the remedy of baking soda solution to prevent mildew. So I drove all the way to up to the Finger Lakes from the New York City area where I live, and stopped in at Sonnenberg Gardens at the head of Canandaigua Lake to see their test rose gardens which were following this regimen of an application every 3rd day. Wasted trip. They had no money in their budget to provide water to the roses, and in that particular year, the rainfall must have been pitifull, for most of the roses had dropped dead, and those which were still alive, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Penny Problem, Remedy is Potasium Carbonate, not sodium bicarbonate (baking soda) Potassium is more caustic and more costly. Bonide ads say food grade, don't think potasium carb is used used in food that much. I tried Baking Soda at 1 tsp per qt on squash, did not appear to help that much in my garden. Manure tea was a great help in supressing early blight, Definately going to try it for mildew. Basically I have the same weather as you, Almost 12 weeks of rain, 48F expected tonight, Did not water my veggie garden until July 5th this year. About 2/3rds of my hot peppers in the ground. Not as much fungal infections yet, that I expected. Byron
