Imazethapyr plus propanil programs in imidazolinone-resistant rice
Weed Technology 25 (2), 204-211
Abstract: Field studies were conducted in 2008 and 2009 near Crowley, Louisiana, to evaluate the addition of different propanil formulations in mixture with a standard imazethapyr program of 70 g ai ha⁻¹ early postemergence followed by (fb) 70 g ha⁻¹ late postemergence. Weeds evaluated included red rice, barnyardgrass, Texasweed, and alligatorweed. Control of all species with treatments, including a propanil formulation applied at 3,400 g ai ha⁻¹, was equivalent to, or greater than, the standard imazethapyr program. Rough rice yield and economic returns were maximized when the propanil formulations of Propanil 1 or Propanil 3 were mixed with imazethapyr in the early postemergence applications. The addition of propanil to imazethapyr increased rough rice yield and economic returns because of improved weed control.
