David Yarborough


Professor and Extension Blueberry Specialist

Degree: Ph.D. 1991, University of Massachusetts
Phone: 207.581.2923
Email: davidy@maine.edu
Location: 414 Deering Hall

Website: Extension blueberry site

Professional Interests: Blueberry horticulture and weed/crop ecology

Research: Research program emphasizes weed-crop ecology and weed-crop interaction using competition experiments and determining weed thresholds in wild blueberries in Maine.  Data from these experiments have been used to develop a weed management approach to be used in an integrated management program to improve production efficiency of the wild blueberries.  He now does research on developing chemical and cultural strategies for controlling weeds, and works with wild blueberry growers in Maine and Canada to educate them on best management practices that will enable them to increase their efficiency of production and their profitability, so that this industry may continue to remain competitive in the world marketplace.  He has published well over 300 research and Extension publications dealing with wild blueberries and with weeds.  He was recognized by the IR-4 program when he received the Meritorious Service Award in 2006, was elected as a fellow of the Northeastern Weed Science Society and received a Faculty Applied Research Award from the University of Maine Cooperative Extension in 2016.
