Trials were conducted on spring-transplanted (13 May) broccoli (cv. Green Comet) at the Horticulture Field Research Center in Ft. Collins, CO. Individual plots consisted 20 ft long single rows with 15-in in-row spacing, arranged in a randomized complete block design with four replications. Insecticide applications were made 3 Jun and 21 Jun using a CO2 compressed air sprayer delivering 15 gpa at 30 psi in two passes directed along the sides of the planting. An organosilicant spreader (Kinetic, 6 fl oz/A) was added to all treatments. Evaluations were made by visual observations of flea beetles on six plants/plot.
