Abstract

Cultivation timings were used in conjunction with postemergence herbicides to determine their effect on sicklepod control in soybean. Treatments using cultivation alone resulted in less than 70% sicklepod control. A postemergence application of chlorimuron following metribuzin applied postemergence was usually more effective in controlling sicklepod with cultivation 7 days after application than with cultivation 3 days before or at application, or with no cultivation. Cultivation at any timing in conjunction with a postemergence application of imazaquin following imazaquin preemergence improved sicklepod control compared to imazaquin without cultivation. Sicklepod control with chlorimuron postemergence followed by cultivation 7 days after application was as good as or better than two sequential applications of chlorimuron with no cultivation. Imazaquin or metribuzin preemergence followed only by cultivation provided less than 80% control in two of three experiments.
