| Abstract/Contents: | "Commercial sod production has been taking place since the 1920's. Sod growers must have weed-free, high-quality sod to sell their product. The objective of this trial was to evaluate the effects of mesotrione, a relatively new herbicide in the turfgrass market, on sod regrowth after harvest and sod strength at the time of harvest. Tifway bermudagrass sod was harvested on 24 May 2008 and five different rates of mesotrione were applied at different timings during the regrowth of the sod. Herbicide injury and turfgrass cover were evaluated seven days after each herbicide application. Sod was harvested three weeks after final herbicide application (17 October 2008) and percent harvestable sod and sod strength were evaluated. There were no significant effects of mesotrione on turfgrass coverage for any of the application dates. There were no significant differences for herbicide injury except for the final application date, when the highest rates of mesotrione caused more severe injury than other rates. The highest rate (0.5 lb ai/A) of mesotrione applied at six and nine weeks after initial treatment had a negative effect on sod quality and produced less harvestable sod with weaker sod strength compared to most other treatments. There were no significant differences between any of the treatments at label rates (less than 0.5 lbs ai/A annually) in regard to sod strength." |
