Glufosinate-Resistant, BAR-Transformed Rice (Oryza sativa) and Red Rice (Oryaz sativa) Response to Glufosinate alone and in Mixtures

摘要

Glufosinate applied postemergence alone and in mixture with pendimethalin, thiobencarb, quinclorac, propanil, bensulfuron, bentazon, acifluorfen, or triclopyr was evaluated on bialaphos- resistant (BAR) rice and red rice in field studies. Glufosinate at 2.2 kg ai/ha alone was less phytotoxic (6/100) to BAR-transformed rice than when it was applied in combination with 0.4 kg ai/ha triclopyr (59/100) or 0.6 kg ai/ha acifluorfen (22/100). Rice yield with glufosinate alone was similar to the weed- free check the first year, but 13/100 less than the weed-free check the second year.
