‘Copenhagen Market’ cabbage was seeded 4 Apr and transplanted 17 May to a field at the Colorado State University Horticulture Research Farm, north of Ft. Collins, CO. Single row plots were established, each consisting of 5 plants at a 15-in in-row spacing, arranged in a randomized complete block design with 4 replications. Sprays were applied on 5 and 15 Jun using a hand-operated compressed air sprayer delivering 25 gpa. Plots were evaluated by counting all flea beetles on the center 3 plants of each plot.
