WAE: weeks after emergence; NS: nonsignificant; Chl + Flu + Pyr: chlorimuron + flumioxazin + pyroxasulfone; where no significant interaction () is present, insecticide seed treatment main effect is given below and marked with a cross. For responses that did not produce a herbicide by insecticide seed treatment interaction, a -test was conducted to compare treatments with no insecticide to each insecticide seed treatment within an herbicide. Where use of an insecticide seed treatment reduced injury or increased height or yield compared to no insecticide, means are marked with a double dagger (‡).
