Abstract
Two new herbicides quinclorac or known as BAS 514. H and bensulfuron or known as DPX-F5384 were evaluated. Quinclorac at 0.25 kg a.i./ha applied 10 days after sowing (DAS) completely controlled Echinochloa crus-galli whose efficacy was comparable to that of molinate at 3.0 kg a.i./ha 2 4-D Isobutyl ester (IBE) at 1.0 kg a.i./ha whilst bensulfuron at 0.03 kg a.i./ha did not provide any control. Both quinclorac and bensulfuron caused slight but temporary phytotoxic effect on rice seedlings control of a broader spectrum of weed species was achieved when applied as mixtures. Although quinclorac could well be an alternative choice over that of molinate 2 4-D IBE its application in combination with bensulfuron would be a better substitute if the control for sedges was also needed. Grain yield was largely dependent on the efficacy of control of E. crus-galli with the tested herbicides.
