"A thorough inspection of the sprayer's plumbing system is crucial. Confirming the main filter is clean, ensuring selector valves are set correctly, and checking for leaks or worn components can prevent costly mistakes."
"Nozzle wear is often overlooked, as rate controllers can mask the issue. Manual testing is essential to determine whether wear is within acceptable limits, typically no more than 10 per cent variance."
"Calibration doesn't stop at the nozzles. Verifying the rate controller using a timed jug test allows growers to confirm whether the system is applying the intended rate or if adjustments are needed."
""The jug doesn't lie," emphasizes the importance of verifying real-world performance rather than relying solely on in-cab readings to ensure accurate application rates."
Growers must ensure their sprayers are properly set up and calibrated before applying treatments to winter wheat. Key steps include inspecting the plumbing system, checking for leaks, and confirming nozzle condition. Nozzle wear can lead to inaccurate applications, so manual testing is necessary to ensure output is within acceptable limits. Calibration should also include verifying the rate controller through a timed jug test to confirm the system's performance matches intended application rates. These practices help manage costs and protect crop performance.
