Plant Pathology Research and Instructional Activities

Your support powers cutting-edge research in plant disease diagnostics, focused on vegetable and field crops across California. Working hand-in-hand with farm advisors statewide, our researchers tackle the most challenging plant health issues—especially those where symptoms are ambiguous or current diagnostic tools fall short. When potentially new or emerging diseases are detected in California, we preserve and study these pathogens to better understand their impact and protect crops locally and globally. With your help, we can stay one step ahead of threats to plant health and food security.
