Abstract

Sicklepod control mid-season in cultivated soybean was higher when imazaquin plus AC 263,222 or AC 263,222 alone was applied POST following pendimethalin plus imazaquin PPI compared with only the PPI treatment. Pendimethalin plus imazaquin PPI followed by imazaquin plus AC 263,222 at 36 + 18 g ai/ha or followed by AC 263,222 at 18 g ai/ha with cultivation controlled sicklepod equal to pendimethalin PPI followed by imazaquin plus AC 263,222 at 71 + 18 g ai/ha or followed by a sequential application of AC 263,222 at 13 g ai/ha early POST followed by 9 g ai/ha late POST. Control with these treatments was no higher than for the standard of pendimethalin plus metribuzin PPI followed by chlorimuron POST at 9 g ai/ha, which controlled 86% sicklepod. Averaged across herbicide treatments, cultivation reduced percent sicklepod seed in harvested soybean samples 33% and increased soybean yield 19% compared with no cultivation. Soybean yield was highest for the chlorimuron standard and greater than that for the other treatments when averaged across cultivation treatments.
