Abstract/Contents:"Methiozolin is applied five or more times per year to control annual bluegrass in cool, temperate areas, but high market demand in the Southern US and recent registration in Australia expands the products use in variable climates. To better design weed control programs for variable turf types, more information is needed to characterize methiozolin dissipation in different turf systems. Methiozolin was applied biweekly thrice to twelve hybrid bermudagrass putting greens in Virginia. Soil samples were collected immediately following each application and biweekly for 12 additional weeks. Methiozolin was extracted from each soil sample and analyzed using liquid chromatography with tandem mass spectrometry. Methiozolin dissipation in the one-month span of three sequential applications differed between years. Methiozolin concentration immediately following the third biweekly application to hybrid bermudagrass greens was approximately 105 and 180% of the concentration immediately following the initial application, in 2021 and 2022, respectively. This difference in methiozolin accumulation following three applications was attributed to differential hybrid bermudagrass green up during methiozolin treatments each year. Despite differences in post-treatment methiozolin concentration between years, the temporal dissipation rate later into the summer was consistent. Following the final application hybrid bermudagrass greens, methiozolin dissipated 50 and 90% in 14 and 46 d, respectively. These data suggest that the previously reported 49-day methiozolin half-life from laboratory dissipation studies may not adequately describe field conditions."
