What is an adjuvant?

An adjuvant is a substance that is added to a pesticide formulation to enhance the effectiveness of the active ingredient. Adjuvants can improve various properties such as the spreading, adhesion, penetration, or stability of the pesticide, ultimately leading to better efficacy in pest control. They can help ensure that the pesticide adheres well to the surface being treated or that it penetrates into plant tissues more effectively, thus improving overall performance.

In the context of pesticide application, understanding the role of adjuvants is crucial for improving outcomes and ensuring that the pesticide performs as intended. Other options like type of pesticide, method for application, or safety equipment do not accurately describe what an adjuvant is or its specific function in enhancing pesticide effectiveness.
