You must calibrate granule application equipment each time you change granular products.

Calibrating granule application equipment each time a different granular product is used is essential for ensuring accurate application rates. Each product may have different physical characteristics, such as size, weight, and density, which can affect how the granules flow through the equipment and how they are distributed. Proper calibration helps to ensure that the correct amount of product is applied to the target area, which is crucial for effectiveness and for minimizing the risk of applying too much, which can lead to environmental harm or damage to the treated area.

Failure to calibrate for each different granular product can result in inconsistent application rates, potentially leading to ineffective pest control or unintended consequences, such as harming non-target organisms or plants. Thus, obtaining the right calibration for each specific product is fundamental to maintaining safety and efficacy in pest management practices.
