The latest free guides from WSU Extension include a new training curriculum aimed at tree fruit growers and other agricultural producers, as well as a study materials form for spray users and professionals.
• Spray Nozzle Demonstration Curriculum (EC010E)
WSU educators developed this curriculum as a resource for growers and their employees, exploring function and challenges associated with different nozzles used in common agricultural sprayers. Readers will learn the difference between types, and how nozzle wear leads to deviations in spray pattern and rate. This curriculum is used in conjunction with Common Interchangeable Nozzles for Perennial Crop Canopy Sprayers (FS352E). Authored by WSU Department of Horticulture Research Assistant Margaret McCoy, Regional Extension Specialist Gwen Hoheisel, and Viticulture Extension Specialist Michelle Moyer.
• WSU Pesticide Study Materials Order Form (C0886)
This is a revised order form showing current titles and prices of study materials; it helps professionals and spray users prepare for Washington State Department of Agriculture pesticide licensing examinations.
