Abstract

Cultivations in conjunction with POST applications of AC 263,222 were evaluated for their effects on sicklepod and pitted morningglory control and soybean yield. Cultivation alone controlled sicklepod and pitted morningglory season-long no more than 30%. In most instances, one cultivation with herbicides improved sicklepod and pitted morningglory control compared with no cultivation, but two cultivations did not further improve control. Two applications of AC 263,222 at 9 or 13 g ai/ha per application with a single cultivation caused the most soybean injury and were no more efficacious than imazaquin applied PRE followed by 9 g/ha AC 263,222. Imazaquin applied PRE followed by AC 263,222 at 18 g/ha plus one or two cultivations were the only treatments that controlled sicklepod and pitted morningglory more than 90% season-long. Cultivation in combination with herbicides increased yields over that of herbicides used alone. Soybean yield was the highest following imazaquin applied PRE followed by AC 263,222 at 9 g/ha plus two cultivations.
