My applied research is driven by the needs of Indiana
vegetable growers. Research emphasis is split between disease etiology and
disease management. Disease etiology includes recognizing disease threats to
the Indiana vegetable industry and determining how the pathogen causes disease
and impacts production. Research on disease management includes greenhouse and
field trials to determine effective treatments to diseases that threaten
production. Methods of interacting with the vegetable industry include: extension
publications such as the Midwest
Vegetable Production Guide for Commercial Growers as well as several
bulletins on particular diseases; newsletter articles in the Vegetable Crops Hotline as well as other
newsletters; presentations made to vegetable growers in Indiana and throughout
the US; field visits; Youtube videos; phone calls and, increasingly, emails.
