Which of the following is NOT a function of activator adjuvants?

Activator adjuvants play a significant role in enhancing the effectiveness of pesticides and other agricultural sprays by modifying their physical properties to improve application performance. Their functions typically include wetting, which allows the pesticide to spread more readily over the surface of the target plant; spreading, which ensures that the product covers a larger area effectively; and sticking, which helps the pesticide adhere to the target surface for a longer period.

Fermentation, on the other hand, is a biological process involving the conversion of sugars to acids, gases, or alcohol using microorganisms. It is not related to the functions of activator adjuvants in pesticide formulations. Therefore, identifying fermentation as a function clearly separates it from the roles that activator adjuvants actually fulfill in enhancing pesticide efficacy.
