Thanks, Zuzu -- my main concern is for squash and cucumber plants; I did find an article from the Univ. of New Hampshire extension service at this site http://extension.unh.edu/resou...
-- in part, it states:
"All pumpkins and squash will develop powdery mildew symptoms if weather conditions favor the fungus.
Resistant or tolerant varieties develop symptoms more slowly and maintain leaf coverage later in the
They also list some varieties of pumpkin and squash that are resistant.
Interesting! Thanks, Evan, for bring this up
