Sprayed the Cellulosic Ethanol Study, corn treatments, all replications CE1 (plots 108, 202, 304, and 401) and CE3 (plots 105, 207, 301, and 403) for postemergence weed control in corn. Plots were sprayed over several days with Lexar (S-metolachlor (+ safener) + atrazine + mesotrione) [EPA Reg. No. 100-1201] at 3 qts/acre (7.01 L/Ha), Roundup Power Max (EPA Reg. No. 524-549) (Glyphosate: N-(phosphonomethyl) glycine, in the form of its potassium salt, 48.7%) at 22 oz/A, and Ammonium Sulfate (sprayable, CAS #7783-20-2) at 3.4 lbs/A with the Lexar being applied either solo or as a tank mix with the Roundup + AMS, depending on what was available in the spray tank at that time. Spray dates were 6/17, 6/20 and 6/21. All plots received the final spray amounts of Lexar at 3 qts/A, Roundup PowerMax at 22 oz/A and AMS at 3.4 lbs/A. Weather conditions depended on the day. Equipment Used: JD 5220 tractor traveling 4.6 mph (gear C1, 1400 rpm) with a pull type Top Air Sprayer equipped with a hydraulic centrifugal sprayer pump and a Raven 440 automatic carrier control unit. Turbo TeeJet 11003 nozzles were used, spaced 15 inches apart with a total boom length of 30 feet. 20 psi were used. Water applied at 20 gals/A, (187 L/ha), was used as the carrier.
