WAE: weeks after emergence; NS: nonsignificant; Chl + Flu + Pyr: chlorimuron + flumioxazin + pyroxasulfone; means followed by an asterisk indicate a significant herbicide by insecticide interaction () or a significant injury reduction via insecticide seed treatment, within the same herbicide, compared to no insecticide. Where no significant interaction is present, insecticide seed treatment’s main effect is given below and marked with a cross.
