If the field to be replanted is especially weedy, a soil-applied herbicide may be needed on the second planting. To reduce the potential for crop injury to the replanted crop, select a herbicide that is suited to the soil and weed situation, but which is not in the same chemical family as the herbicide that was used at the original planting. For example, if the first crop of corn was treated with pendimethalin (Prowl), replanted corn should not be treated with Prowl. Use the Cultural and Chemical Weed Control in Field Crops publication (University of Minnesota Publication # 3157) to choose a herbicide from another chemical family that will control the weed species present in the field. Choose a herbicide that, when applied late in the growing season, will not present a carryover problem to the next year’s crop.
