What is a recommended practice when treating large areas?

Metering herbicide into the suction side of the pump is a recommended practice when treating large areas. This method allows for a more controlled and efficient distribution of the herbicide throughout the treatment area. By using a metering system, the applicator can ensure that the correct concentration of the herbicide is delivered, minimizing waste and reducing the likelihood of over-application, which can lead to environmental harm and non-target effects.

In contrast to this effective method, applying herbicides at maximum pressure could result in uneven application and increased drift, potentially impacting surrounding non-target areas. Limiting herbicide use to specific zones is a more targeted approach but may not be feasible in all situations where a large area needs treatment. Using only manual application methods can be labor-intensive and less efficient for larger applications, making it impractical for extensive areas that require herbicide application. Thus, metering enhances precision and safety in the application process.
