<jats:title>Abstract</jats:title>
<jats:p>Cabbage was transplanted on 1 Jul at the Vegetable Crops Research Farm near Geneva, NY. To increase populations of thrips, a 5-ft strip of oats was planted along the length of each side of the experimental area. Plots consisted of one 10-ft row with 18-inch plant spacing. Treatments were replicated 4 times in an RCB design. A CO2 backpack sprayer with a one-row boom, having 3 nozzles per row (one over the top and one drop nozzle on each side) with TXVS-8 hollow cone tips, and delivering 31 gpa at 40 psi and 2 mph, was used to apply applications of each treatment. Javelin WG at 1.0 lb/acre was added to Admire and the check treatments to control Lepidoptera and insure readable plants at harvest. Silwet L-77 spray adjuvant was applied at 0.1% v/v with all foliar treatments. Admire (3 week post-transplant) was applied only on 22 Jul. Admire (5 week post-transplant) was applied only on 5 Aug. Metasystox-R and Warrior treatments were applied only on 14, 20, and 27 Aug. Warrior fortnightly treatments were applied only on 6, 20 Aug, 5, 15, 28 Sep, and 13 Oct. Other treatments were applied on 6, 14, 20, 27 Aug, 5, 15, 22, 28 Sep, 6 and 13 Oct. Harvest evaluations for thrips were done on 20 Oct. Evaluations for thrips damage were done by randomly selecting 2 mature heads per plot, cutting them in half along the core, and peeling back 10 layers. Each layer was assessed for the presence of thrips injury. To compare treatments, we used the average number of layers per two plants in a replicate and then analyzed these averages. Data were analyzed by a two-way ANOVA.</jats:p>
