Abstract/Contents: | "Two sulfometuron-resistant biotypes of Italian ryegrass were identified from rights-of-way of U.S. Highway 49E in Holmes County, MS, and State Highway 14 in Humphreys County, MS. Sulfometuron at 5.2 g ai/ha applied PRE or POST reduced shoot fresh weight of these selections 20% or less at 4 wk after treatment. As susceptible 'Gulf' Italian ryegrass was reduced 52% or more in shoot fresh weight by 0.5 g/ha sulfometuron applied PRE or POST. The biotype from Highway 49E was reduced 47% or less in shoot fresh weight by 520 g/ha sulfometuron applied PRE or POST." |
