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 season. For more information about controlling powdery mildew, see the New England Vegetable Management Guide, found online at http://www.nevegetable.org/.
All varieties should be trialed on a small scale to determine whether they are suitable for your growing conditions, and markets.
