Fig. 1. Leaf area index (LAI) for each soybean cultivar and herbicide combined over years. Vertical lines indicate the LSD (P = 0.05). Treatments included nontreated soybean; glyphosate at 840 g ha-1 plus ammonium sulfate at 20 g L-1; bentazon–acifluorfen at 1030 g ha-1 plus thifensulfuron at 2.2 g ha-1, sethoxydim at 240 g ha-1, UAN, and COC at 1.5% (vol./vol.); and lactofen at 105 g ha-1 plus bentazon at 1120 g ha-1, clethodim at 140 g ha-1, UAN, and COC at 1.5% (vol./vol.)
