| Abstract/Contents: | "Field experiments were conducted at Abilene Country Club in Abilene, TX in the summer of 2007 to quantify the efficacy of V-10142 to control yellow and purple nutsedge. Studies were located on established infestations of yellow and purple nutsedge present in a common bermudagrass rough cut to a height of 5.0 cm. 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 XR8004VS nozzle tips and calibrated to deliver 304 L/ha at 220 kPa. Treatments were initiated on July 10, 2007 and included an untreated check, V-10142 at 0.56 kg ai/ha followed by V-10142 at 0.56 kg ai/ha at various timing intervals (1, 2, 3, or 4 WAIT), V-10142 at 1.12 kg ai/ha, and trifloxysulfuron at 0.03 kg ai/ha for comparison. Each plot was assessed at the time of initial herbicide application for percent cover of yellow or purple nutsedge. Visual estimates of percent yellow and purple nutsedge control and bermudagrass phytotoxicity were taken 1, 2, 3, 4, 6, 8, and 12 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 study. Among the four sequential treatments, V-10142 followed by V-10142 3 WAIT provided the highest control (100%) of purple nutsedge 6 WAIT and control levels remained high (91%) 12 WAIT. V-10142 followed by V-10142 2 or 4 WAIT gave excellent control (97%) of purple nutsedge 6 WAIT, but control declined to 82% 12 WAIT. V-10142 at 1.12 kg ai/ha and sequential applications of V-10142 (0.56 kg ai/ha) 1 week apart gave good control (90 and 81%, respectively) 6 WAIT, but control declined to 71 and 42%, respectively, 12 WAIT. The standard, trifloxysulfuron, gave excellent control (99%) of purple nutsedge 6 WAIT, but control declined to 80% 12 WAIT. In the yellow nutsedge experiment, all treatments provided excellent control (100%) of yellow nutsedge 6 WAIT. This level of control was maintained by all treatments except V-10142 followed by V-10142 1 WAIT. Control following this treatment declined to 90% 12 WAIT." |
