A study was conducted in Stoneville and Verona, MS, to evaluate control of failed stands of corn and soybean with different herbicide treatments and application timings, as well as control of failed stand of corn with soybean planted 1 and 7 DAT (days after treatment). Clethodim plus glyphosate proved most effective across all growth stages of corn with > 90% control 7, 14, and 21 DAT. Paraquat plus metribuzin provided the greatest control of a simulated failed corn stand 3 DAT compared with all other treatments. Pooled across all herbicide treatments, 49% control was achieved when replant occurred 7 DAT compared with 46% following replant 1 DAT. These studies demonstrated clethodim plus glyphosate was most effective in control of failed stands of corn as well as the benefits of not replanting immediately after herbicide treatment. Paraquat and paraquat plus metribuzin both provided > 90% control 3, 7, and 14 DAT.
