| Abstract/Contents: | "Field experiments were conducted at Meadowbrook Country Club in Lubbock, TX in the summer of 2009 to quantify the efficacy of DPX-MAT28 for the postemergence control of dandelion. Studies were located on established infestations of dandelion 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 375 L/ha at 221 kPa. Treatments were initiated on June 10, 2009 and consisted of liquid applications of DPX-MAT28 at 0.052, 0.078, and 0.105 kg ai/ha; a granular application of DPX-MAT28 at 0.078 kg ai/ha; and carfentrazone + 2,4-D + mecoprop + dicamba at 0.45 kg ai/ha. Visual estimates of percent dandelion control and bermudagrass phytotoxicity were taken 1, 2, 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. Bermudagrass phytotoxicity was greatest (19%) with applications of DPX-MAT28 at 0.105 kg ai/ha 2 WAIT. All other DPX-MAT28 treatments exhibited <= 10% phytotoxicity 2 WAIT. Bermudagrass recovery from DPX-MAT28 treatments was observed 4 WAIT. No bermudagrass phytotoxicity was observed in plots treated with carfentrazone + 2,4-D + mecoprop + dicamba throughout the length of the trial. All DPX-MAT28 treatments exhibited 100% dandelion control 4 WAIT, while control with carfentrazone + 2,4-D + mecoprop + dicamba was 95%. Control with carfentrazone + 2,4-D + mecoprop + dicamba decreased to 77% 12 WAIT, while control with DPX-MAT28 ranged from 90 to 96% 12 WAIT regardless of application rate. No differences in dandelion control were observed between liquid and granular applications of DPX-MAT28 throughout the length of the trial." |
