Sorry your having so much rain Worth. There is little that can be done to stop the damage of too much rain for too long. We are having the exact opposite problem. I dread my next water bill. The good side is diseases are usually far less in dry times but things grow slower and tomatoes and other fruits don't set as well.
I used the bleach spray on English peas multiple times this year and it really slowed down the mildew. Each day after spraying they would look so much better for a few days or a week before the powdery mildew would start showing up again. It extended their life by about 3 weeks and so extended the harvest and production. I used slightly less then 5 ounces of Clorox to a gallon of water. Next year I may use it a bit stronger since their seemed to be no negatives at the strength I used. I use this slightly weaker mix on cucumbers and squash as soon as I see the first signs of mildew on the underside of any leaves.
