Structural Pest Control Applicator Practice Exam

What is necessary to calibrate granular application equipment?

1. The ground speed of the spreader

2. The weight of granules over a known area

3. The total amount of granules in the spreader

4. The type of granular product used

The correct answer is: The weight of granules over a known area

To effectively calibrate granular application equipment, it is essential to determine the weight of granules applied over a known area. This measurement is critical because it allows the applicator to ensure that the correct rate of application is being achieved to target pests effectively while minimizing waste and potential environmental impact. By measuring the actual weight of granules distributed over a specified area, you can compare this to the desired application rate, making any necessary adjustments to the spreader's settings or movement speed. While understanding the ground speed of the spreader, the total amount of granules in the spreader, and the type of granular product used are all components of the application process, they do not directly inform the calibration itself. The ground speed influences distribution, but without knowing how much product is actually being spread over a specific area, it cannot be used effectively for calibration. Similarly, the total weight of granules in the spreader is relevant before starting, and the type of product can affect spread patterns, but calibration primarily hinges on the exact delivery of the product to the targeted treatment area.
