Abstract
Abstract Treatments were applied to plots that were 8 rows (40 inches wide) × 75 ft long. The experimental design was a complete randomized block with 4 replications. Seed and soil treatments were applied at planting on 6 May with a John Deere 7100 series planter equipped with granular applicators. The Orthene 80SP seed treatment was prepared prior to planting using 6.4 oz/cwt seed. All plots received an infurrow treatment of Terraclor Super-X fungicide (0.25 + 1.0 lb (AI)/acre). Foliar insecticides were applied with a high-clearance sprayer equipped with a compressed air system for spraying small plots, delivering 2.5 gal/acre with two X-3 hollow cone nozzles/row. Early season foliar treatments were initiated at pinhead square stage and applied 5 times (21 and 27 Jun and 3 and 10 Jul. Sweep net data were collected by making 25 sweeps/plot on 20 and 26 Jun and 3 and 8 Jul. Heliothis and boll weevil damage was assessed on 15 Jul by pulling 25 squares/plot. All plots were oversprayed with Capture 2EC 0.04 lb (AI)/acre for major pest control on 15, 25 and 31 Jul, 19 and 28 Aug and 6 Sep. The test was defoliated with Def (6) 1.2 pt/acre on 13 Sep., Four rows from each plot were mechanically harvested on 20 Sep and 8 Oct. Yields were converted to lb sc/acre.
