What term describes the liquid material that a pesticide is added to for application?

The correct term for the liquid material that a pesticide is added to for application is "Carrier." In pesticide application, the carrier is crucial as it helps deliver the active ingredient of the pesticide to the target area. The carrier can be water, oil, or another liquid that facilitates the even distribution of the pesticide. By using a carrier, the pesticide can effectively penetrate the surface it is meant to treat, ensuring optimal efficacy.

Understanding the role of a carrier is essential for effective pest control, as it impacts how well the pesticide performs in the intended environment. It also helps in minimizing drift and ensuring that the pesticide reaches the targeted pests, which is fundamental for both effectiveness and safety in pest management practices.
