Fill the 79-litre tank with the appropriate chemical mixture according to product label instructions and ensure all boom nozzles are clean and functioning. Tow the sprayer behind your vehicle at a consistent speed, maintaining even boom height (typically 45-60cm above the target) to ensure uniform coverage. Calibrate your application rate by calculating: litres per hectare = (nozzle output in L/min × 60) ÷ (speed in km/h × boom width in metres). Always wear appropriate personal protective equipment and refer to the chemical product label for safety requirements, application rates, and re-entry intervals. Tips: Start each season by conducting a nozzle output test—spray each nozzle into a container for one minute to identify blocked or worn nozzles that could cause uneven coverage. Keep your boom level and parallel to the ground to maintain consistent spray height, and travel at a steady speed to avoid over- or under-application. Maintain detailed spray records including date, location, paddock size, chemical used, application rate, weather conditions, and operator name to comply with Queensland agricultural chemical recordkeeping requirements.
