I would like to know some varieties of cucumber, squash, melon, and pumpkin which are resistant or immune to powdery mildew.

Powder Mildew fungi thrive under conditions of high relative humidity, warm temperatures, low light, high fertility and succulent plant growth. Pumpkins and melons vary in their resistance to powdery mildew; the best defense is to provide full sunshine and ample air circulation between the plants. Resistant cucumber varieties include 'Calypso', 'Cherokee', 'Dasher II', 'Monarch', and 'Supersett'. 'Senator' is a resistant zucchini.
