Note: CK, the no herbicide negative control; A0, a preemergence nonspecific herbicide for maize, dinitraniline (the active control); A1-A4: four preemergence maize specific herbicides, nicosulfuron+atrazine, alachlor+acetochlor+atrazine, propisochlor+atrazine, and acetochlor+atrazine, respectively.
