Technical Abstract: The purpose of this study was to evaluate ZA1296 and other herbicide programs for weed control in corn. The study was established at the University of Illinois South Farm, Urbana. The soil was a Flanagan silt loam with a pH of 6.5 and 4.0% organic matter. Pioneer 34A14 corn was planted 1.5 inches deep on April 28 in 30 inch rows. Treatments were arranged in randomized complete blocks with four replications of plots 7.5 by 40 feet. Herbicides were applied with a CO2 backpack sprayer delivering 20 gpa and equipped with 8003 flat fan nozzles for preemergence applications and 8002 flat fan nozzles for postemergence applications. Plots were not cultivated after planting. Corn tolerance was very good to adequate with all of the treatments evaluated. Some treatments caused slight, temporary injury to corn plants. Control of annual weed species present in the study was excellent with a number of the mixtures. Treatments that included ZA1296 early postemergence following acetochlor preemergence were outstanding in that injury was nil, weed control was excellent well into the season, and yields were among the highest in the study.
