| Abstract/Contents: | "Field experiments were conducted at Meadowbrook Country Club in Lubbock, TX in the summer of 2008 to quantify the efficacy of several herbicides for the postemergence control of puncturevine (Tribulus cistoides L.). Studies were located on established infestations of puncturevine 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 C2 backpack sprayer equipped with XR8003VS nozzle tips and calibrated to deliver 304 L/ha at 276 kPa. Treatments were initiated on July 3, 2008 and consisted of metsulfuron at 0.036 or 0.072 kg ai/ha, sulfentrazone at 0.21 or 0.28 kg ai/ha, carfentrazone at 0.017 or 0.034 kg ai/ha, sulfosulfuron at 0.066 or 0.105 kg ai/ha + NIS at 1.0% v/v, trifloxysulfuron at 0.033 or 0.050 kg ai/ha, and 2,4-D + MCPP + dicamba + carfentrazone at 0.22 or 0.44 kg ai/ha. Visual estimates of percent puncturevine control and bermudagrass phytotoxicity were recorded 1, 2, 4, and 6 weeks after initial treatment (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. Puncturevine control declined with herbicide rates; therefore, only treatments containing the highest rates will be discussed. 2,4-D + MCPP + dicamba + carfentrazone exhibited 99% control followed by sulfosulfuron (76%) 2 WAIT. All other treatments exhibited <= 50% control 2 WAIT. Puncturevine control with 2,4-D + MCPP + dicamba + carfentrazone remained high (98%), while control with metsulfuron increased to 99% 6 WAIT. Moderate control (79%) was observed with trifloxysulfuron treatments 6 WAIT. All other treatments exhibited <= 43% control 6 WAIT. This experiment will be replicated in time." |
