First up for programs is Rob Curtiss, Michigan State University special projects coordinator at the Washington Tree Fruit Research Commission, talking about sterile codling moth distribution in the orchard. His presentation starts at 9 a.m.
He works with growers, WSU faculty and staff, and others to develop a technology road map for orchard automation and mechanization research and development, according to the commission’s website He has a bachelor’s degree from the State University of New York and a master’s from WSU. He is working on his doctorate in entomology at Michigan State University.
Before joining the commission in 2017, he was the Hawaii state entomologist.
At 9:30 a.m., Betsy Beers of the WSU Tree Fruit Research and Extension Center, Wenatchee, will talk about sterile insect release for codling moth control.
For the past 25-plus years, her research has been in integrated pest management of apple pests, both those feeding directly on fruit and those dining on roots, shoots and foliage, according to her WSU website.
She has also studied integrated and biological control, arthropod phenology and life history, host plant associations, economic injury levels, effects of herbivory on plant gas exchange, sampling, non-target effects of pesticides on natural enemies, and pesticide resistance.
After a 10 a.m. break, a program on “good guys” in orchards will be presented by Chris Strohm, WSU Extension, and Tobin Northfield, WSU entomologist.
Strohm has a background in biology, ecology and forest entomology. He worked as a crop scout and consultant for dairy and vegetable producers in upstate New York and south Florida before moving to WSU in 2017.
Northfield is an assistant professor in entomology integrated pest management and biocontrol at the tree fruit center in Wenatchee. He has doctoral and master’s degrees from WSU.
He is researching insect ecology to identify sustainable pest management strategies in tree fruit groups, according to WSU. Northfield previously was a U.S. Department of Agriculture post-doctoral fellow, and lecturer/senior lecturer in northern Australia.
Beers will give a secondary pest update at 10:45 a.m. Those pests include apple maggot, clear wing, apple leaf curl midge and BMSB.
Gary Grove, a WSU plant pathologist from Prosser, will talk about cherry powdery mildew management and fungicide resistance at 11:10 a.m.
Grove has been with WSU since 2006. Before that, he was director of the Washington Agricultural Weather Network. His research is in epidemiology and management of fungal diseases of stone fruits and grapes.
At 11:40 a.m. Tianna DuPont of WSU Extension will talk about fire blight.
DuPont is a tree fruit extension specialist with the WSU Tree Fruit Research and Extension Center, Wenatchee.
Her program works to bring research-based information to the tree fruit industry through trainings, applied research, technology and consultations. Programs include organic production, sustainable pest and disease management, soil and water management, next generation tree fruit network, and increasing knowledge and application of tree fruit best management practices.
Lunch is planned from 12:15-1 p.m.
The afternoon sessions are geared toward Spanish speakers.
At 1 p.m., DuPont will cover flight blight management, or “Manejo de Fuego Bacteriano.”
The 1:30 p.m. session on pesticide safety, “Cuidando su Salud en la Huerta,” will be led by Alexandra J. Lewis Lorentz, AJL Productions and Central Washington University.
Lewis-Lorentz’s company, AJL Productions, is a video production business that combines digital arts with her experience as a cultural anthropologist. She is a lecturer and adjunct faculty member in the anthropology department at CWU.
Kaz Lorentz of Bluebird will talk about codling moth management, or “Palomilla de Manzana,” at 2 p.m.
He is on Bluebird’s field staff and is a former tree and vine crop adviser at the McGregor Co., Quincy.
At 2:30 p.m. DuPont will present “Conociendo los Insectos Buenos en la Huerta,” or “Getting to Know the Good Guys in Our Orchards.”
Attendees can claim their pesticide education credits after the morning and afternoon sessions.
