Star-of-Bethlehem control in no-till corn

摘要

This study was designed to determine the effectiveness of corn herbicides for burndown control of star-of-Bethlehem. The study was conducted at an off-station location in Marion, IL. Herbicide applications preceded the crop and were applied 28 days before the planned planting date (28EPP). Weed control was rated 14 days after application and could not be rated at planting as planting was delayed and star-of-Bethlehem in the nontreated plots was dying naturally by that time. Plots were 10 ft wide, 30ft long arranged in a randomized complete block design with 4 replications. The herbicides were broadcast applied with a CO_2 pressurized sprayer using 8003 flat fan tips at 40 PSI in 20 GPA water.
