Sweet corn can be sensitive to new herbicides and crop tolerance needs to be evaluated.
The soil was Nyssa silt loam with pH 8.1 and 1.2 percent organic matter. Plant population was 29,000 seeds per acre on 30-in rows. Plots were 10 ft wide by 30 ft long and replicated three times in the efficacy trials and four times in the tolerance trials. Plots were organized in a randomized complete block design within each trial. Herbicide treatments were applied with a CO 2 -pressurized backpack sprayer delivering 20 gpa at 30 psi.
