Abstract
Field studies were conducted at Carbondale, IL from 1992 to 1994 to evaluate rhizome johnsongrass control in field corn with nicosulfuron and primisulfuron applied POST without or with EPTC applied PPL EPTC applied PPI at 4480 and 6720 g ai/ha plus dichlormid controlled johnsongrass 38 and 60% in 1992 and 29 and 41% in 1993, respectively, and 0% in 1994. EPTC did not decrease johnsongrass rhizome weight, length, or number of nodes in any year. Nicosulfuron at 35 g/ha and primisulfuron at 40 g/ha applied to 38-cm tall plants controlled 94 to 100% and 85 to 100%, respectively, from 1992 to 1994. Plots treated for three consecutive seasons with nicosulfuron or primisulfuron did not have any rhizomes. Corn yield was more than double in nicosulfuron and primisulfuron plots compared with control plots.
