Postemergence Weed Control Systems Without Dinoseb for Peanuts (Arachis hypogaea)

Abstract
Postemergence treatments utilizing various combinations of fluazifop-P, paraquat, and 2,4-DB were compared to a preplant-incorporated (PPI) application of benefin followed by a ground-cracking application of alachlor and dinoseb plus naptalam and a postemergence application of 2,4-DB for weed control, peanut yield, and net economic return to land, overhead, and management. The greatest peanut yields (3-yr average of 4510 kg/ha) and net returns (3-yr average of 136/ha, respectively, compared to the same system without paraquat and 2,4-DB.
