What defines a low-volume spray?

A low-volume spray is defined as a broadcast application that utilizes 30 gallons per acre or less. This method emphasizes efficiency and precision in pesticide application, which can lead to reduced pesticide usage while still achieving effective control of target pests. By using less volume, the application minimizes environmental impact and reduces the potential for runoff and drift.

This approach is often employed in situations where high water volumes would not only be wasteful but could also lead to adverse effects on non-target organisms and the surrounding ecosystem. Low-volume applications are particularly beneficial in forestry and agricultural settings where managing pesticide inputs is crucial for sustainability and compliance with regulatory standards.

The other options either specify quantities above 30 gallons per acre, restrict the application method to ground rigs without considering aerial application, or suggest applications that are not broad, which do not align with the definition of low-volume spraying. Thus, defining low-volume spray accurately focuses on the total application rate relative to the area treated.
