Abstract

Field experiments were conducted in Tifton, Midville, and Athens, GA to determine economic net returns from PRE-broadcast, PRE-banded, POST, and POST-directed herbicide treatments and inter-row cultivation in conventional-tillage soybean. Metribuzin applied PRE-broadcast was more effective for sicklepod and morningglory control than PRE-banded. Soybean net returns were not significantly reduced in two of three years in plots treated with metribuzin applied PRE-banded compared with broadcast application. The addition of POST or POST-directed herbicides increased treatment net returns over PRE-broadcast and PRE-banded metribuzin two of the three years of the study. No significant soybean injury was observed.
