Wow. Just the topic I was going to bring up this week. Disease.
I’ve had problems with powdery mildew and late season blight for years.
This is the first year I’ve actually got some squash & cukes that look like we’ll be able to actually eat some. (Frying up squash blossoms right now - yum!), but some of the plants are showing signs of powdery mildew. Been spraying everyday with Serenade. Seems to be slowing the problems down at least.
Late season blight just seems to be everywhere here in southern CT. I’ve noticed it in trees and weeds even. I just keep my tomatoes pruned and remove any part of the plant that shows signs of it. Seems to go after the potatoes too, but doesn’t seem to effect the tubers the way it effects the tomatoes.
What does everyone else do to deal with these problems?
I seem to remember that some use dilute solutions of bleach or baking soda. Maybe they’ll see your post and chime in.
I haven’t actually had much in the way of blight. Gardens Alive has some nice pictures in their catalog of various problems and products for sale to treat them:
