Abstract
Abstract Field experiments were conducted in the spring of 1994 at the V. G. James Research and Extension Center in Plymouth, NC and 1995 at the Gaylon Ambrose farm near Washington, NC. A RCB test design was employed each season. Plots in each year were 6.0 ft X 50.0 ft with 6.0 ft alleyways between plots. Insecticide applications were made on 21 Apr 1994 and 28 Apr 1995. Treatments were applied by a CO, powered backpack sprayer equipped with three hollow cone Tee Jet® X-8 nozzles spaced 1.5 ft apart. The sprayer delivered 14.9 gpa at 44.0 psi which provided an effective spray swath of 4.5 ft when operated at 2.0 ft above the canopy. Treatments were evaluated four days after application by taking 25 and 15 sweeps from each plot in 1994 and 1995, respectively. The sweep net had a standard 1.0-inch.
