Dr. Gary E. Vallad

Associate Professor, Plant Pathology Department

Dr. Gary Vallad’s research and extension program focuses on the diagnosis and management of diseases common to vegetable and ornamental production with an emphasis on the development and implementation of bio-based disease management strategies.  His research utilizes traditional and contemporary approaches to study pathogen biology, disease epidemiology, and plant-pathogen interactions.  Current projects are focused on the management of diseases caused by Alternaria spp., Corynespora cassiicolaFusarium spp., Sclerotium rolfsii, Pseudomonas spp., and Xanthomonas spp. in vegetable and ornamental production; and strategies for managing soilborne pests and pathogens in raised-bed, plasticulture production systems.
