A field study was conducted to evaluate pre, sequential pre/post, and postemergent weed control in conventionally-tilled, glufosinate-resistant field corn. A randomized complete block design with three replications per treatment was utilized. The study was conducted on a Kennebec silt loam with 2.4 percent organic matter and a pH of 6.9. Seedbed preparation consisted of disking one week prior to planting and one field cultivation the day of planting. Individual plots consisted of six 30-inch rows, each 30 feet long. 'Pioneer 33G28LL' corn was planted May 16 at a population of 24,200 seeds/acre. Treatments were applied with a tractor-mounted sprayer traveling 2.5 mph.
