| Abstract/Contents: | "Experiments were conducted under greenhouse conditions to determine the effect of soil organic matter and clay content on the efficacy of sethoxydim and quizalofop applied as preemergence treatments. A Hyde sandy loam soil with an organic matter content of 9.9% was modified with a structurless quartz sand to investigate a range of organic matter contents (0, 1, 2, 4, 6, 8, and 10% w/w). In separate experiments a montmorillionite clay was incorporated into the quartz sand at 0, 2, 4, 6, 8, and 10 % w/w. Results were compared to similar treatments applied to soils collected from several locations in North Carolina's Piedmont, Coastal Plain, and Tidewater regions. Organic matter greatly reduced the efficacy of both sethoxydim and quizalofop on large crabgrass as the rate of each herbicide was reduced and the organic matter was increased from 0 to 10%. Montmorillionite clay decreased the activity of sethoxydim while no decrease in the herbicidal activity was observed with quizalofop. Similar results were observed in the collected soils. While it is not economically feasible for either sethoxydim or quizalofop to be applied as preemergence treatments for the control [of] grass weeds, it is important to recognize their full potentials." |
