Abstract

Flufenacet at 200–500 g ha⁻¹, applied before or after first irrigation resulted in 40 to 69% and 44 to 72% control of grassy and broadleaf weeds, respectively. Metribuzin at 200 to 400 g ha⁻¹ provided control of both grassy (75–90%) and broad leaf weeds (79–93%). Metribuzin beyond 300 g⁻¹ was toxic to wheat. Sulfosulfuron resulted in higher grain yield due to very effective control of grassy (87–90%) and suppression of broadleaf weeds (35%), however, it was statistically at par with clodinafop at 60 g ha⁻¹, fenoxaprop at 120 g ha⁻¹ and metribuzin at 200 and 300 g ha⁻¹.
