| Abstract/Contents: | "Mesotrione (2-(4-Mesyl-2-nitrobenzoyl)-1,3-cyclohexanedione) is a relatively new selective herbicide marketed as Tenacity (Syngetnta, 2001). Mesotrione is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) enzyme inhibitor that prevents the production of carotenoids in susceptible plants resulting in a bleaching response. It can be applied pre- and post-emergent and effectively controls clover (Trifolium sp.), creeping bentgrass (Agrostis sp.) and annual bluegrass (Poa annua) in Kentucky bluegrass (Poa pratensis) turf stands. In this experiment, we assessed the responses of Kentucky bluegrass cultivars and selections to mesotrione herbicide at seeding in a growth chamber. All eighty-nine entries from the 2017 National Turfgrass Evaluation Program Kentucky bluegrass test plus one additional selection were evaluated for their response to a high label rate (230 g ha-1) treatment of mesotrione at the time of seeding and 31 days after seeding (DAS). Entries were seeded in 10.2 cm square pots filled with a fine silica sand and potting mix blend at a 50/50 ratio by volume. Utilizing randomized complete block design, each selection was present twice in each of the four blocks with one treated (water, mesotrione and a non-ionic surfactant) and one un-treated control (water and non-ionic surfactant). Applications were made using a track sprayer with water carrier at 410 L ha-1. Digital images were captured using a light box at days 14, 18 and 22 DAS of the experiment for a total of 3 image sets for digital analysis. Percent green cover was determined using imageJ and the results were subjected to statistical analysis. After bleaching subsided, 55 DAS, biomass samples were taken, excluding the roots, to evaluate the difference in establishment from the treated control. Cultivar dependent responses to mesotrione were observed among Kentucky bluegrass entries. PPG-KB 1131 and Barvette HGT exhibited very little injury in both runs while Selway, A06-8 and PST-K13-143 were susceptible to the mesotrione application in both runs." |
