What is the white powder growing on my pumpkin leaves, causing them to die? What can I do to stop it from spreading to the new leaves?

Pumpkins, and other squash plants, grow best in the long, warm summer days. When nighttime temperatures get cool, especially cool and moist, the leaves become susceptible to powdery mildew. The summer season is winding down, even in your region, and the plants are beginning to die. Allow the leaves and vines to die naturally, then harvest your pumpkins by cutting them from the plants, along with 3-4 inches of stem. Allow the pumpkins to dry in the sun until the stems shrivel and turn gray. Then put them in a cool, dark location for storage.
