Program Interests

The goal of my extension education and adaptive research program is to develop integrated management strategies for important and emerging diseases of the major vegetable crops grown in Pennsylvania and provide statewide leadership in the area of vegetable pathology. Specifically these responsibilities include working with research faculty, extension specialists and county-based educators to develop integrated pest and crop management strategies to address important and emerging diseases of the major vegetable crops grown in Pennsylvania as well as use existing and new technologies to provide growers and other ag service providers with research-based information on pathogen biology, epidemiology and vegetable disease management.

Current research/extension projects include the elucidation and management of onion bacterial diseases, identification of soilborne pathogens associated with tomato high tunnels and management using anaerobic soil disinfestation, identification of bacteria associated with blackleg and soft rot of potato, as well as the population biology of Verticillium dahliae associated with potatoes in Pennsylvania.

I also conduct trials evaluating the efficacy of conventional and biorational products for the management of commonly occurring diseases on tomatoes, snap beans, onions and cucurbits in PA. With increasing concern about fungicide resistance and cost of inputs, selection of the most effective fungicides/biopesticides is an important component of an IPM program.

Most recently, a team of Penn State Extension Educators and Specialists received funding from the Pennsylvania Department of Agriculture Specialty Crop Block Grant to establish sustainable hops production recommendations for the Pennsylvania hops industry using integrated pest management tools. For the latest information on this project follow up on Facebook at the Penn State Extension Hops Project!

As part of larger regional and national projects, I also participate in pest monitoring and prediction efforts for cucurbit and basil downy mildews (http://cdm.ipmpipe.org/index.php) and tomato/potato late blight (http://usablight.org) that help disseminate timely information about confirmed outbreaks that growers can  use to make in-season disease management decisions. For the latest information regarding disease and insect outbreaks and vegetable crop production, visit our Vegetable and Small Fruit Extension Team website.
