| Abstract/Contents: | "Annual bluegrass (Poa annua L.) is one of the most problematic weeds in high maintenance turfgrass. Its lime green color contrasts that of desired turfgrass species, giving the turf a blotchy, mottled appearance and disrupting the overall color uniformity. Field experiments were conducted at Lake Ridge Country Club in Lubbock, TX during the fall of 2009 to determine the efficacy of AE 1170437 (indaziflam) for the preemergence control of annual bluegrass. Studies were located in a hybrid bermudagrass fairway cut to a height of 1.3 cm with a history of annual bluegrass infestation. Plots measured 1.5 x 1.5 m and were arranged in a randomized complete block design with four replications of treatments. Treatments were applied using a CO2 backpack sprayer equipped with XR8003VS nozzle tips and calibrated to deliver 304 L/ha at 276 kPa. Treatments were initiated on September 16, 2009 and consisted of AE 1170437 at 0.030, 0.040, 0.050, and 0.060 kg ai/ha; and prodiamine at 0.56 and 0.84 kg ai/ha. Visual estimates of percent annual bluegrass control and bermudagrass phytotoxicity were taken 1, 2, 3, 4, 6, 8, and 10 WAIT. Data were subjected to analysis of variance (ANOVA) and means were separated using Fisher's Protected LSD at the 0.05 significance level. No bermudagrass phytotoxicity was recorded throughout the length of the trial regardless of treatment. Indaziflam treatments exhibited 100% annual bluegrass control 4 and 10 weeks after initial treatment (WAIT) regardless of application rate. Prodiamine treatments exhibited 91 to 96% control 4 WAIT and 95 to 96% control 10 WAIT regardless of application rate." |
