Alan Eaton

Alan Eaton

University of New Hampshire Cooperative Extension

Areas of Expertise: rodents, ticks, apples, blueberries

IPM Tools: biological control, cultural control, education, exclusion/avoidance, monitoring

Bio: Alan has been coordinator of UNH Cooperative Extension’s integrated pest management work since 1978. The work involves managing pests of tree fruit, small fruit and vegetables. He also extensively works on ticks (especially blacklegged tick, which spreads several human diseases here). We (the IPM team) provide educational programs and publications to assist people in managing pest problems. While commercial agriculture is our primary focus, the creation of a national IPM road map helped us broaden our scope, and we also work with backyard gardeners, and anyone who is a potential victim of tick bite.

Collaboration Interest: With retirement looming, I am not seeking long term collaborations, but may be interested in short-term collaborations on voles or ticks.

Donna Ellis

Donna Ellis

University of Connecticut, Department of Plant Science and Landscape Architecture

Areas of Expertise: invasive terrestrial plants, ornamentals

IPM Tools: biological control, education, monitoring, mapping invasives

Bio: Donna Ellis is a Senior Extension Educator in the Department of Plant Science and Landscape Architecture at the University of Connecticut, where she has worked for 27 years. She has a B.S. degree in Plant Science from the University of Rhode Island and an M.S. degree in Plant Science from the University of Connecticut.

Donna is the UConn Integrated Pest Management (IPM) Program Coordinator and conducts IPM training programs for nurseries and garden centers. She teaches two courses at UConn on agricultural and horticultural plant pests and is involved with educational outreach and applied research programs for insects, weeds, and plant pathogens, with an emphasis on invasive plants and biological control. Donna initiated a Beetle Farmer Program to train volunteers to raise beneficial insects as biological control agents for the invasive plant purple loosestrife (Lythrum salicaria). Together with the Beetle Farmers, approximately 2 million beetles have been introduced in Connecticut for control of this invasive species. Since 2009, Donna has collaborated with other scientists to release beneficial weevils for biological control of another invasive plant, mile-a-minute weed (Persicaria perfoliata).

Donna serves as Co-Chairperson of the Connecticut Invasive Plant Working Group (CIPWG), a statewide organization whose mission is to provide invasive plant education. The Working Group convenes biennial symposia on invasive plants.

Collaboration Interest: Biological control of terrestrial invasive plants.

Jeff Garnas

University of New Hampshire

Areas of Expertise: fungi, forest insects and pathogens

IPM Tools: biological control, host resistance, modeling

Bio: I am a population and community ecologist and have focused on invasive insects and pathogens in forest systems. I am interested in understanding the evolutionary ecology of invasion, including genetic consequences of population bottlenecks and admixture on adaptive evolution in invaded ecosystems. I currently work with a number of systems including the emerald ash borer, the southern pine beetle, and beech bark disease, among others.

PhD Plant Pathology, Simon Fraser University, Burnaby, BC, Canada

MS Plant Pathology, Oregon State University, Corvallis, OR, USA

Professional Experience:

Extension Associate Professor (5/2017–present), West Virginia University

Program focus: Integrated disease management of fruits and vegetables with emphasis on strawberries, tomatoes, and cucurbits. Specific responsibilities are:

  • Disease diagnosis at WVU Plant Diagnostic Clinic and sending recommendations to growers
  • Development of IPM based plant disease management tools for sustainable crop production
  • Research and teaching on “Integrated Pest Management of Vegetables and Small Fruits”
  • Development and implementation of decision support system for growers and investigation on fungicide efficacy in growers field and research farms

Extension Assistant Professor (6/2011–5/2017), West Virginia University

  • My major research focus is sustainable management of diseases in small fruits and vegetables. I strongly believe plant disease management should be a package of judiciously arranged options encompassing host resistance, use of disease free seeds and transplants, planting in appropriate site and providing balanced nutrients to maintain good plant vigor, careful intercultural operations to minimize environmental stress, and use of plant protection materials if needed. Exploitation of host resistance has been on the top of the list of my research and will continue to be so for sustainability of crop production and feed ever increasing population. Host resistance and varietal potential of resistance to diseases need to be exploited and incorporate it in the package of disease management tools. I also work on developing and utilizing sensitive diagnostic tools for disease management recommendations.

Collaboration Interest: Regional efforts on applied research for developing sustainable disease management options in fruits and vegetables. I am specifically interested in fungicide resistance, disease forecasting, and soilborne disease management in strawberries. Screening and development of beneficial microbes based products for plant health, productivity, and quality.
