Tree Disease Diagnostics: Identifying and Treating Fungal and Bacterial Pathogens.

This advanced PHC webinar provides ISA Certified Arborists with a science-based framework for diagnosing and managing tree pathogens. Participants will distinguish biotic/abiotic symptoms, use diagnostic tools, and explore treatment strategies aligned with ISA standards.

Learning Objectives:

• Identify symptoms and signs of common fungal and bacterial tree diseases
• Distinguish between biotic and abiotic disorders
• Apply integrated treatment strategies using cultural, chemical, and sanitation-based interventions
• Use field and lab diagnostic tools to confirm pathogen presence
