Who is responsible for calibrating granular spreaders before application?

The person who will make the application is responsible for calibrating granular spreaders before use. Calibration is essential because it ensures that the spreader applies the correct amount of pesticide or fertilizer accurately, which is critical for effectiveness and safety. Proper calibration helps prevent over-application or under-application, both of which can lead to pest control failures or environmental harm.

A trained applicator needs to understand the specific requirements of the product they are using, as well as the spreader's mechanics, to achieve the desired coverage and dosage. This responsibility lies directly with the individual who will be operating the spreader, ensuring they are familiar with the equipment and knowledgeable about the application rates needed for effective pest management.
