What is the main objective of calibration?

• A. Ensure that all the parts of the sprayer are working properly
• B. Determine the quantity of pesticide that you will need to apply
• C. Ensure that the proper rate of chemical is applied to the target area
• D. Determine the time required to treat a specific area

Answer: (C)

Calibration is about delivering the chemical at the correct rate per unit area. It ties together how fast you move, how wide your spray swath is, and how much liquid comes out of the nozzle, so you can apply the labeled rate exactly where you intend. This matters because applying too little can leave pests untreated, while applying too much wastes product, costs more, and increases environmental risk. By calibrating, you translate your sprayer’s performance into a specific amount of chemical per acre (or per hectare), ensuring efficacy and compliance with the label. In practice, you measure how much liquid the system puts out over a known distance or time, combine that with the spray width and your travel speed, and calculate the gallons per acre you’re applying. If that rate isn’t at the label-recommended level, you adjust (nozzles, pressure, or speed) until you reach the target rate. So, the main objective is to ensure the proper rate of chemical is applied to the target area.
