Debra Ann Inglis
Professor and Extension Plant Pathologist
Research Specialty and Interests
The WSU-Mount Vernon research and extension program in vegetable pathology focuses on the biology and management of fungal and oomycete diseases of fresh and processing vegetables, particularly red and yellow potatoes and other high-value specialty vegetables. Current field, greenhouse and laboratory research projects are on (i) diseases of specialty potato tubers, (ii) late blight on potato and tomato; (iii) vegetable diseases under biodegradable crop covers and in high tunnel systems, (iv) flooding as a rotation alternative to preserve shorebird habitat and manage soilborne potato pathogens in western Washington.

Western Washington supports one of the most abundant and diverse vegetable industries in the United States. Both fresh and processing vegetables and vegetable seed crops are grown here. Because of the region’s mild marine climate, plant pathogens, especially fungi, are prevalent, and can negatively impact yield, quality and production costs. The WSU Mount Vernon vegetable pathology program, through numerous and varied extension activities (field days, breakfasts, written materials, commodity meetings, training sessions, visiting scientists), provides information to growers on ways to manage diseases of fresh and processing vegetable crops, and better understand plant pathogens. General vegetable disease education and outreach includes leadership in the Pacific Northwest Vegetable Extension Group, PNW-VEG
