Effect of Growth Stage on the Efficacy of Postemergence Herbicides on Four Weed Species of Direct-Seeded Rice

Figure 3

Effect of postemergence herbicides (BisNa, bispyribac-sodium; Fx + etho, fenoxaprop-p-ethyl + ethoxysulfuron; Px + cyh, penoxsulam + cyhalofop) on aboveground dry biomass (g) and control (%) of junglerice when sprayed at its four-, six-, and eight-leaf stages. Mean comparisons were performed based on least significant difference test at 5%.
