N2  - The activity, absorption and translocation of fluazifop-butyl ((+-)-2-(4-((5-trifluaromethyl)-2-pyridinyl) oxylphenoxy) propanic acid) in upland rice (Oryza sativa L.) and in three grass weeds were determined in field, greenhouse, and laboratory studies at the International Rice Research Institute [Los Banos, Laguna, Philippines]. Fluazifop-butyl injured rice more when applied at pre-tillering or early tillering than when applied at tillering or late tillering. Rice recovered from initial injuries immediately after herbicide treatment, with the faster and more complete recovery at lower herbicide rates and/or later applications. Control of grasses was excellent at 0.05 kg ai/ha fluazifop-butyl or higher, applied not later than two days after rice emergence. Goosegrass (Eleusine indica (L.) Gaertn. no. 3 ELEIN) was more susceptible than itchgrass (Rottboellia conchinchinensis (Lour.) Clayton no. ROOEX) or junglerice (Echinochloa colona (L.) Link no. ECHCO). E. indica also translocated more 14C-fluazifop-butyl than did rice or the other weed species. At 24 h after foliar application of C14-fluazifop-butyl, radioactivity, in parts outside the treated leaf of goosegrass was 40 times higher than in rice, itchgrass, or junglerice
