Understanding Plant Disease Management with Dr. Sara Villani
In this seminar, Dr. Sara Villani from North Carolina State University presents an insightful discussion on plant disease management. As an assistant professor specializing in fruit and woody ornamental pathology, Sara outlines practical research on fungicide and antibiotic resistance, the impact of abiotic stressors on diseases, and various management strategies. The talk covers general plant disease tactics used in fruit crop and ornamental pathology, a new dieback issue affecting maples, redbuds, and dogwoods, and the role of fungicides and biological products in disease control. Her extensive experience and dedication to disease management have significantly benefitted the North Carolina apple industry.

Dr. Sara Villani, an assistant professor at NC State, delivered a seminar on plant disease management, focusing on challenges in the Southeast. She highlighted the importance of accurate diagnosis, understanding disease development, and the specific challenges posed by the region’s warm, humid climate. A significant portion of her talk addressed a newly observed dieback issue affecting redbud, dogwood, and maple trees. This dieback is potentially linked to Serrata basidium, though this has not been confirmed. Villani provided strategies for managing these issues, including proper cultural practices, biological controls, and fungicides, but acknowledged the difficulties in prescribing treatments without a fully identified causal agent. The seminar underscored the complexities of managing plant diseases in the Southeast, where environmental conditions often exacerbate the spread and severity of pathogens.
