Several additional cucurbit crops were added to the Quintec label and the changes are not in the 2010 Vegetable Recommendations book. Quintec is labeled for powdery mildew control on winter squash, gourds and pumpkin in addition to watermelon, cantaloupe and other melons such as honeydew and others. Rates range from 4-6 fl oz/A. See label for details. This is a good powdery mildew fungicide and should be used in rotation with other fungicides for powdery mildew. Be sure to read the label to avoid fungicide resistance.
