Abstract
Treatments were evaluated for control of a heavy population of strawberry root weevil and some black vine weevil. Treatments were replicated 4 times in a 2 year-old ‘Totem’ strawberry field in Burlington, WA. Plots measuring 3 rows wide and 25 ft long were arranged in a RCB design. Five 1 ft2 samples were randomly taken on 20 Jul from the middle row of each plot beginning at 10 PM with the aid of a flashlight. Sprays were applied on 18 Jul with a field sprayer at 100 psi delivering 100 gpa of finished spray from a hand-held boom with 3 hollow cone D4-45 TeeJet nozzles at 2 mph. Air temperature was 80° F and NW wind speed 3-5 mph.
