| Abstract/Contents: | "Field experiments were conducted at Lake Ridge Country Club in Lubbock, TX in the summer of 2007 to quantify the efficacy of foramsulfuron with various spray adjuvants to control dallisgrass. Studies were located on established infestations of dallisgrass 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 June 22 and consisted of foramsulfuron (0.15 kg ai/ha) applied alone or in combination with methylated seed oil (1.0% v/v), crop oil concentrate (1.0% v/v), non-ionic surfactant (0.25% v/v), or each of the three plus urea ammonium nitrate (UAN) (2.5% v/v). Sequential applications for each treatment were made 1 WAIT (week after initial treatment). Visual estimates of percent dallisgrass control and bermudagrass phytotoxicity were taken 1, 2, 4, and 6 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 (< 5%) was recorded 2 WAIT regardless of treatment, but recovery was observed by 3 WAIT. Treatments containing COC or NIS exhibited greater dallisgrass control 6 WAIT (43 to 55%) compared to foramsulfuron applied alone (38%). The addition of UAN resulted in a biological increase in dallisgrass control 6 WAIT compared to treatments without UAN. All treatments resulted in dallisgrass re-growth from rhizomes 8 WAIT. This experiment will be replicated in time and additional foramsulfuron application timings will be investigated." |
