Which term refers to the chemicals that do not possess pesticidal activity but improve application effectiveness?

The term that refers to chemicals that do not have pesticidal activity but enhance the effectiveness of pesticide applications is known as inert ingredients. Inert ingredients are substances included in pesticide formulations that help improve the distribution, stability, and effectiveness of the active pesticide components.

These ingredients might include surfactants, emulsifiers, or stabilizers, which facilitate the pesticide's ability to adhere to surfaces, disperse evenly, or remain stable during storage. Unlike the active ingredients that directly control pests, inert ingredients play a crucial role in optimizing the overall performance of the pesticide product.

Understanding the function of inert ingredients is vital for effective pesticide application because they can influence how well the active ingredients perform under various conditions. Their role is often essential in ensuring that the pesticide is both effective and safe when used.
