What type of control adjuvant should be added to spray solutions for application using powered equipment?

Drift control adjuvants are specifically designed to reduce the potential for pesticide drift during application. When using powered equipment, such as sprayers, minimizing drift is crucial for ensuring that the pesticide remains targeted on the intended area and does not accidentally affect non-target plants, wildlife, or water sources. Drift can be caused by factors like wind, equipment pressure, and droplet size, and a drift control adjuvant works to modify these variables by enhancing the physical properties of the spray solution.

This type of adjuvant typically increases droplet size or alters the surface tension, resulting in a more stable and directed spray pattern that helps to keep the pesticide application focused on the intended area. This is particularly important in Maine, where proximity to sensitive environments such as water bodies or organic farms could amplify the consequences of unintended drift.

While the other options serve important roles in different contexts, they do not primarily address the specific need to control drift during the application process.
