Which of the following is NOT considered a benefit of using adjuvants in pesticide formulations?

Using adjuvants in pesticide formulations is primarily aimed at enhancing the effectiveness of the active ingredients, which is why improved efficacy, better coverage, and enhanced penetration are all recognized benefits. Adjuvants can help ensure that the pesticide adheres better to the target surface, covers it uniformly, and allows for deeper absorption into the plant tissue, thus maximizing the potential benefits of the pesticide application.

In contrast, increased volatility is not a beneficial effect associated with adjuvants. High volatility can lead to the rapid evaporation of the active ingredients, which decreases their effectiveness and increases the risk of off-target movement. Thus, while adjuvants are designed to optimize the pesticide's performance, increasing volatility contradicts this goal and is not a desirable outcome in pesticide formulation.
