Comment:
Sprayed the Nitrogen Rate Studies (N-rate), both the irrigated and non-irrigated studies. Roundup Weathermax (glyphosate) was applied at 16 oz/A (1.17 L/ha), and AMS was applied at 17 lbs/100 gals of water. A total of 80 oz of Roundup, and 17 lbs of AMS was applied on the N-rate study area. Weather Conditions: Sunny with air temperature was 74 degrees F. Wind was out of the northeast at 0-8 mph averaging 3 mph. Time of application was between 5:15 p.m. and 5:45 p.m. Equipment Used: JD 5220 tractor traveling 4.5-5.0 mph (gear C1) 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. 30 psi was used. Water applied at 20 gals/A, (187L/ha), was used as the carrier. Purpose of Application: Control of volunteer corn (non-roundup ready corn). Sprayed postemergence. Srayed Roundup on both N-rate studies. Because we replanted both of these studies the volunteer corn from the first planting time needed to be reovmed.
