“Oak Wilt, Bacterial Leaf Scorch, or Something Else?” Webinar

Many factors can cause oak leaves to scorch, wilt, and defoliate, making accurate diagnosis challenging. This webinar will help participants distinguish between oak wilt, bacterial leaf scorch, and abiotic stressors such as drought by focusing on key symptoms and field patterns. Timed to coincide with the onset of these issues, the session offers practical guidance on field evaluation, sampling, and management strategies. Participants will build confidence in diagnosing oak health problems and learn about free tools and resources to support accurate identification and effective management. This webinar is offered at no cost. A $10 registration fee is required to receive PA pesticide, International Society of Arboriculture, Society of American Foresters, and Pennsylvania Landscape and Nursery Association credits.
