Abstract
Abstract Treatments were replicated four times in a 10-year-old ‘Meeker’ red raspberry field in Vancouver, WA. Plots measuring 1 row wide and 30 ft long were arranged in a RCB design. Full coverage sprays were applied on 2 Jun with a tractor-mounted 6-tank plot sprayer with an over-the row-boom using 14 D3-45 TeeJet nozzles per row at 200 psi, 2 mph to deliver 130 gal/acre. The nozzles were spaced 10 inches apart and began 12 inches above the soil line. Sampling consisted of randomly removing 10 terminal mature leaflets , from each side of each plot between 3-5 ft high at 3, 7, 14, and 28 DAT. MSM female counts were made by brushing them onto glass plates with a mite-brushing machine.
