Field horticulturists from Chelan Fruit Cooperative examine beneficial insects during a hands-on workshop offered in February. Inset: Angela Gadino discusses natural-enemy monitoring techniques with Leo Garcia during a workshop preceding the WSU Sunrise Orchard Field
Implementing stable biological control programs requires growers and pest managers to have a much better understanding of management actions against not only pests, but also their natural enemies. Sound management strategies must consider the phenology
Washington State University entomologist Dr. Stan Hoyt developed integrated mite control in the late 1960s (see “How integrated mite control works”).
Over the last four decades, integrated mite control has saved Washington fruit growers millions of
Washington State University viticulture extension specialist Dr. Michelle Moyer suggests growers consider the following when developing a disease management program:

So, what can orchardists
Generations of growers have monitored the key pests in their orchards. Over the years, traps and lures available to growers have evolved. Yet, the goal has always been to develop easy-to-use, sensitive, and selective trapping
Pear and apple orchardists have a fairly broad field of products to use in controlling fireblight—and it should get even more crowded in the coming year with new registrations anticipated, says an Oregon State University
