How do you ensure that a spray system delivers the correct rate?

• A. Perform regular calibration, follow label rates, maintain equipment, and verify outputs with measurements.
• B. Rely on memory and do not check outputs.
• C. Calibrate only once after purchase.
• D. Use random rates and hope for good results.

Answer: (A)

Getting the right spray rate comes from calibrating the system under real operating conditions, using the label’s recommended rate, keeping the equipment in good condition, and verifying the actual output with measurements. Regular calibration shows exactly how much product is being delivered at your chosen speed, pressure, and nozzle setup, so you can adjust to hit the label rate accurately. Following the label ensures both legal compliance and effective pest control, while ongoing maintenance prevents changes in flow caused by worn nozzles, clogged filters, or leaks. Verifying outputs with measurements—using methods like the catch-can test or flow meters—confirms the delivered rate and helps you correct any drift or uneven distribution. Relying on memory, calibrating only once, or using random rates can lead to under- or over-application, reducing effectiveness and increasing environmental risk.
