Comment:
Sprayed the soybeans, preemergence, on the KBS Dairy field Turner (field 12). Started on the west tree line and sprayed towards the east. A total of 15 acres was treated. First Rate (cloransulam-methyl) was applied at 0.6 oz/A, (42 g/ha) and Dual II Magnum (s-metolachlor (+ safener)) was applied at 1.33 pts/A (1.56 L/ha). A total of 9 oz of First Rate and 2.5 gals of Dual II Magnum were applied on 14.82 acres (6 hectares). Weather Conditions: Sunny with air temperature 69 degrees F. Relative Humidity was 42%. Wind was out of the west-northwest at 0-8 mph's averaging 5 mph's. Time of application was between 12:45 p.m. and 1:45 p.m. Equipment Used: JD 5220 tractor traveling 5.5 mph (gear C1, 1700 rpm's) 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 annual broadleaves and grass weeds. Sprayed preemergence. The sprayer was loaded for the LTER treatment 1 with the listed spray solution and volume when the PTO driven centrifugal pump shaft broke, we replaced the pump with a new hydraulic centrifugal pump. The solution was in the sprayer for 4 days before the pump was fixed. With the recommendation from Jim Kells it was decided to spray this load out on a KBS Dairy field and have a new tank load and material for the LTER treatment 1.
