Speakers

Betsy Beers, Professor and Entomologist, WSU Department of Entomology, Tree Fruit Research and Extension Center. Beers has worked for 30+ years on integrated pest management of apple and cherry pests.

Vaughn Walton is the Horticultural Entomologist in the Department of Horticulture at Oregon State University. His work focuses on biology and management of key pests in perennial horticultural crops.  His work has resulted in several technologies of that have been adopted into industry.

Gary Grove is a Professor in WSU Department of Plant Pathology. His work focuses on epidemiology and management of fungal diseases of stone fruits; disease forecasting and fungicide resistance management.

Tobin Northfield is an Assistant Professor for WSU Department of Entomology. He leads an interdisciplinary task force comprising researchers and representatives from government and industry that works to improve management X-disease and Little cherry disease. He leads a project focusing on X-disease vector management including the use of cultural controls such as Surround and Extenday.

Scott Harper is an Assistant Professor for WSU Department of Plant Pathology. His research program focuses on viruses and other systemic pathogens of perennial crops in the Pacific Northwest.

Mike Basedow is a Tree Fruit Specialist for Cornell Cooperative Extension. Mike delivers educational programming and conducts applied research relevant to orchards across the Eastern New York region, primarily in the areas of cultural orchard practices and pest management.

Matt Whiting is a Professor of Horticulture for Washington State University. His focus is on: whole-tree physiology, high efficiency orchard architecture, incorporating automation/mechanization in fruit production systems, environmental control of fruit quality, and pollination biology.

Theresa Pitts Singer has worked as a Research Entomologist at the USDA-ARS Pollinating Insects Research Unit in Logan, UT since 2002.  Her research on alfalfa leafcutting bees and blue orchard bees focuses on specific factors that affect reproduction and pollination efficacy, on chemical cues that are used in nest establishment and individual nest recognition, and on effects of certain pesticides on bee mortality and behavior.

Angie Orpet works with agricultural producers in the inland Pacific Northwest to create pollinator friendly habitat. She has been collaborating with farmers since 2016 to help with resource needs in perennial and annual crops.

Kirti Rajagopalan is part of the Land, Air, Water Resources, and Environmental Engineering emphasis area of the Department of Biological Systems Engineering at Washington State University. Her modeling group develops and utilizes a variety to modeling approaches to better understand and manage water and agricultural resources. The group focuses on trans-disciplinary efforts to problem solving and works closely with colleagues from a broad range of disciplines including engineering, economics, entomology, physiology, statistics, and agronomy.
