| Abstract/Contents: | "A number of new acetolactate synthase (ALS) inhibiting herbicides are being launched into the turf market and several others are soon to follow. As the use of these products has increased, turf managers have raised concerns about their non-target movement from treated areas onto desirable turf. This is especially important when these herbicides are sprayed near warm-season turf that has been overseeded with cool-season grasses. The objectives of our research and demonstration trials were to evaluate the effect of irrigation on down-slope movement of selected ALS herbicides and to assess the impact of ALS herbicide movement via foot traffic. Two replicated trials along with several demonstration trials were conducted during 2003 at the University of Floridas West Florida Research and Education Center near Jay and Indian Bayou Golf and Country Club in Destin, FL. Plots were treated with a CO2 pressurized back pack sprayer fitted with 11002 nozzles calibrated to deliver 190 L ha. In the slope movement studies, rimsulfuron, trifloxysulfuron, foramsulfuron, and pronamide were applied to perennial ryegrass (Lolium perenne) overseeded bermudagrass (Cynodon dactylon X C. transvaalensis). Irrigation was withheld for 24 hours or applied either immediately following herbicide application or one hour after herbicide application. Down-slope injury was measured. At the WFREC, no treatment differences were noted when irrigation was withheld for one hour. When irrigation was withheld for 24 hours, all three herbicides moved an equal distance. When irrigation was applied immediately following herbicide application, trifloxysulfuron moved considerably farther than foramsulfuron and pronamide. Results at Indian Bayou Golf and Country Club were less conclusive. In the movement via foot traffic demonstrations, plots were sprayed with the various herbicides and then either walked through and into untreated Poa trivialis immediately following treatment, two hours after treatment, or the following morning while heavy dew was present. Foramsulfuron, rimsulfuron, and pronamide at 1X rates did not move with foot traffic immediately after spraying, however, trifloxysulfuron, flazasulfuron, and sulfosulfuron did. None of the products tested at 1X rates moved with foot traffic once the herbicides had dried or in heavy dew the morning following herbicide application. Foramsulfuron moved immediately after treatments at 2X rates, but required 3X rates to move after drying and the following day on foliage wet with dew. At 2X rates, trifloxysulfuron, flazasulfuron, rimsulfuron, pronamide, and sulfosulfuron moved via foot traffic even after the materials were allowed to dry and the following day on foliage wet with dew." |
