Abstract/Contents:"Field studies were conducted three times during the summer of 2000 to evaluate herbicide drift. Twelve treatments were evaluated, five nozzles (AI TeeJet, XR TeeJet, Turbo TeeJet, Turbo FloodJet and the Turbo Drop nozzle), and three drift retardants (Placement, Array and Border). The XR TeeJet was tested at 20 and 40 psi. The three drift retardants were tested with each the XR TeeJet and AI TeeJet nozzles. Glyphosate was applied at ten gallons per acre, by a tractor mounted sprayer traveling eight miles per hour. Sorghum was used as the indicator crop to measure glyphosate drift. Measurements taken to determine drift were distance visible injury on the sorghum could be observed (injury line), and distance from the boom that glyphosate drift killed the sorghum (kill line). When the AI TeeJet nozzle was used with Border or Placement, there was a reduction in the distance drift injured the sorghum, compared to the AI TeeJet nozzle alone. The XR TeeJet nozzle with Array reduced the distance of measured sorghum injury compared to the XR nozzle alone. The three drift reducing additives gave no benefit in reducing the kill line compared to the nozzles alone. The ability of a nozzle to reduce drift ranked them: Turbo TeeJet = Turbo FloodJet > AI TeeJet = Turbo Drop = XR TeeJet @ 20 psi > XR TeeJet @ 40 psi."
