| Abstract/Contents: | "Annual bluegrass (Poa annua) ) is a widely distributed seed producing winter annual with a tufted growth habit. Roughstalk bluegrass (Poa trivialis) is a seed producing perennial that also has a tufted growth habit and yellowgreen color. The purpose of this research was to evaluate postemergence control of annual bluegrass and roughstalk bluegrass in creeping bentgrass (Agrostis stolonifera) golf course fairways using Amicarbazone (Xecute 70 DF). The study was conducted on creeping bentgrass fairways at Wade Hampton Golf Course in Cashiers, NC. Plot size for each treatment was 2.0 m by 3.0 m with 4 replications. Treatments were applied using a CO<2> backpack sprayer calibrated at 20 GPA. Treatments for the study included: Amicarbazone at 0.044 lbs ai/a applied April 22, 2010 followed by 6, 12, 20 DAI (days after initial application), 0.0875 lbs ai/a applied April 22 and 20 DAI, 0.131 lbs ai/a applied April 22 and 20 DAI and bispyribac-sodium (Velocity 17.6 SG) at 0.022 lbs ai/a applied on April 22 followed by 12, 26, 40 DAI and sulfosulfuron (Certainty 75 WDG) at 0.012 lbs ai/a applied on April 22 and 12 DAI. Visual ratings were taken throughout the study. Percent creeping bentgrass injury was rated on a 0-100% scale with 0% representing no injury and 100% representing the damage to all bentgrass present. Percent annual bluegrass and roughstalk bluegrass control was rated on a 0-100%, with 0% representing no control and 100% percent representing total control. In addition, a composite rating of stand density was taken on a 0-100% scale with 0% representing no green grass (turfgrass and/or Poa species) ) in the stand and 100% representing total stand density. Overall, 20 DAI (days after initial application) saw 65% turf stand injury from amicarbazone (0.044 lbs ai/a) after 3 applications and sulfosulfuron after 2 applications. Injury decreased to <= 20%, 33 and 40 DAI for all three rates of amicarbazone. Injury from amicarbazone was more severe than bispyribac-sodium treatments at all rating dates, with the exception of 40 DAI. Amicarbazone reduced overall stand density ~45% more than Velocity and Certainty at 33 and 47 DAI. However, amicarbazone provided greater control for annual bluegrass and roughstalk bluegrass than Certainty and Velocity at ~70%. Future research will be continued at Clemson University and Wade Hampton Golf Course where plots will be evaluated for long term effects of treatments. Turf injury in weed-free creeping bentgrass will be assessed. Repeat treatments of amicarbazone and additional products will be evaluated for timing and control of Poa annua." |
