“The best control of six weed species and highest soybean yields were obtained by a,a,a -trifluoro-2,6-dinitro- N,N -dipropyl- p -toluidine (trifluralin) application at the time of seedbed preparation followed by 3-(3,4-dichlorophenyl)-1-methylurea (linuron) application at planting and by linuron application at planting without the early trifluralin application.”
