Quizalofop- p -ethyl Mixed with Synthetic Auxin and ACCase-Inhibiting Herbicides for Weed Management in Rice Production

Year: 2019

Type: article

Abstract: A study was conducted near Crowley, Louisiana, to evaluate the efficacy of quizalofop- p -ethyl mixed with different synthetic auxin and ACCase-inhibiting herbicides for barnyardgrass and weedy rice control in rice production systems. Quizalofop was applied at 0 or 120 g ai·ha −1 mixed with 2,4-D at 1336 g ai·ha −1 , triclopyr at 282 g ai·ha −1 , quinclorac at 420 g ai·ha −1 , cyhalofop-butyl at 314 g ai·ha −1 , or fenoxaprop- p -ethyl at 122 g ai·ha −1 . Cyhalofop, fenoxaprop, 2,4-D, quinclorac, and triclopyr antagonized quizalofop for barnyardgrass control at 14 days after treatment (DAT). At 28 DAT, an antagonistic response persisted for barnyardgrass control, except when cyhalofop was mixed with quizalofop, which indicated a neutral response. Red rice, CLXL-745, and CL-111 control decreased due to antagonism of quizalofop when mixed with 2,4-D. However, quinclorac, triclopyr, cyhalofop, or fenoxaprop mixed with quizalofop resulted in a neutral response for red rice, CLXL-745, and CL-111 control at 28 DAT.
