TL;DR: Pigweeds have become increasingly important in soybean, peanut, and cotton in a limited number of states and sicklepod, nutsedges, and morningglories were the three most troublesome weeds averaged over all crops. (via Semantic Scholar)

TL;DR: All rates of AC 263,222 applied POST and all application methods of AC263,222 at 72 g/ha had better yields than the pendimethalin control and application method had little effect on weed control. (via Semantic Scholar)
