My cucumber plants seem to have a mildew on the leaves, but just the Ferry Morse Spacemaster -my lemon cukes don't have it and neither do my green apples. I've been getting a bunch of cucumbers from these and they taste great.

I read it might be powdery mildew and to use a natural fungicide. What about using baking soda, hydrogen peroxide to a gallon of water, and spray it on the plants? Anyone else having this problem?

Any type of fungicide will work. I prefer liquid copper but a more natural one would be the milk/water spray some people use or apple cider vinegar and water. The trick is to mess the fungi's pH up. I don' know the specifics of the milk or vinegar recipes , so maybe someone who does will fill you in or you might be able to find it on Google.

I had that on my squash and a little on my cukes. Since I didn't want to use chemicals I used a concoction of garlic tea mixed with molasses, garret juice cooking oil and baking soda. It worked.

I don't remember the measurements. There are several recipes out there and I am sure any one would be good to try. You can do a search for baking soda fungicide and you should find something.

I hear Neem oil is good for fungus also.

There were just some studies done on the use of milk for powdery mildew. You mix it 10 parts water to 1 part skim milk and spray it on the leaves. Do a google search for powdery mildew and milk and I'm sure you'll get some more info. I used it on my zukes before they died and it seemed to work. (They died from all the rain we got, not the mildew.)

Yup, try the milk spray, I used it a couple years ago on some lilacs, just out of curiousity, and it really did seem to help.

Good luck,

Pat
