What is the purpose of calibrating a sprayer?

Calibrating a sprayer is primarily focused on ensuring that the correct application rates of pesticides or fertilizers are administered to the landscape or turf area being treated. This process involves adjusting the sprayer to deliver the right volume of liquid over a specific area, which is crucial for achieving effective pest control while minimizing the risk of over-application or under-application.

When the sprayer is correctly calibrated, applicators can accurately apply the correct amount of product needed to manage pests or enhance plant health, which promotes both efficacy and safety. For example, under-application might not effectively control the target pests, while over-application can lead to environmental harm or regulatory violations.

While enhancing the spray pattern, reducing operating costs, and maximizing the area covered can be beneficial outcomes of a well-calibrated sprayer, the primary and most essential purpose remains to ensure that the application rates are correct. This is vital for both effective pest management and compliance with local regulations regarding pesticide use.
