Trials were conducted in Ft. Collins, CO, using transplanted onions (cv. Vega) in single rows at 30-in spacing. Plots were 25-ft in length arranged in a randomized complete block design with 4 replications. Treatments were applied on two dates (14 June, 7 Jul) using a CO2 compressed air sprayer delivering 18.4 gal/A at 30 psi in two passes directed along the sides of the planting. An organosilicani spreader (Kinetic, 6 fl oz/A) was added to all treatments. Application dates varied among treatments. Evaluations were made by examining 10 plants per plot and counting all thrips present in the next area of the onions.
