Powdery Mildew

Powdery Mildew (Erysiphe, Podosphaera, Microsphaera, Golovinomyces, Oidium) is a plant disease commonly encountered in Middle Tennessee's humid climate. Our subtropical conditions — with dew keeping plants wet up to 12 hours daily and nighttime temperatures exceeding 75 degrees F in summer — create ideal conditions for disease development. Early identification and proper treatment are essential for managing this disease in local lawns and landscapes.
