Powdery Mildew of Cucurbits - Podosphaera Fungus Powdery mildew is primarily a disease of cantaloupe, cucumber, pumpkin, and squash. This disease does not require leaf wetness for disease initiation or spread. At vine touch, begin systemic fungicide applications at bush stage of pumpkin growth. Protect pumpkin vines until approximately 21 days from last harvest. Some pumpkin varieties have partial resistance to powdery mildew. Fungicide resistance has been detected in the Midwest. Fungicides in Groups 1 and 11 may not be effective. Fungicides that are affected include Cabrio, Flint, Procure, Quintec, Quadris, Satori, Sovran, Torino and Topsin. Alternate fungicides between MOA groups. Non-Pesticide Cantaloupe/Muskmelon, Cucumber, Pumpkin, Squash, Watermelon | Rotate to non-Cucurbit crops for 2 years. Resistant or partially resistant cantaloupe, cucumber and pumpkin cultivars are available. Prompt destruction of the finished crop with tillage to rapidly breakdown tissue is an important method to prevent disease build-up.
