Abstract/Contents:"Mesotrione is a triketone herbicide soon to be registered for use in turfgrass under the trade name Tenacity™ (Syngenta Professional Products). Tenacity™ will be a product offering control of many annual and perennial broadleaved and grassy weeds. Mesotrione can be applied as a pre or a post-emergence herbicide. This quality will serve as a major benefit to lawn care operators and their approach to weed control in cool season turfgrass. Two trials were initiated on lawn height Kentucky bluegrass (Poa pratensis) in 2007 at Virginia Tech's Turfgrass Research Center in Blacksburg, VA. These trials included 8 treatment options which combined and/or compared the use of mesotrione and standard preemergence and postemergence herbicides to provide broad-spectrum weed control through the growing season. A randomized complete block experimental design with 4 replications was used. Treatments were applied on April 3 (pre), May 15 (early post), July 1 (post), and September 1 (post). Treatments included 4 combinations of a granular formulation of mesotrione plus prodiamine followed by 3 applications of granular mesotrione at varying rates, a granular dithiopyr formulation followed by 3 applications of Trimec® Herbicide (PBI Gordon Corp.) on a 22-0-4 fertilizer carrier, a 22-0-4 fertilizer applied with a foliar broadcast of liquid dithiopyr (Dimension® 2EW, Dow AgroSciences LLC) followed by 2 applications of a 22-0-4 fertilizer applied with foliar broadcast application of Triplet® Sensitive Herbicide (Nufarm Turf & Specialty), 4 applications of a 22-0-4 fertilizer applied alone at 42.6 kg/ha throughout the season, and an untreated check. All of the treatments combining mesotrione with preemergence herbicides controlled smooth crabgrass (Digitaria ischaemum) and dandelion (Taraxacum officinale) 90 to 100% throughout the growing season. Treatments containing regular fertilizer applicationsalone increased turf quality and reduced weed pressure by 50% over the untreated check. Overall turfgrass quality was significantly greater in treated plots than in untreated plots. Mesotrione proved to be an effective addition to a lawn care operator's management program providing an option for preeemergence [preemergence] and postemergence control of broadleaved and grassy weeds."
