Which adjuvant is used to improve adhesion of the pesticide to treated surfaces?

• A. Drift Reduction
• B. Penetrants
• C. Stickers
• D. Surfactants

Answer: (C)

Adhesion of a pesticide to treated surfaces is enhanced by using stickers. Stickers form a thin, flexible film on leaves or other surfaces, helping the active ingredient stay in place even when conditions cause wash-off or abrasion. This improves residue persistence and efficacy. Other adjuvants have different roles: surfactants lower surface tension to improve wetting and spreading; penetrants help the product move into plant tissues; and drift reduction agents minimize off-target movement. While those functions are important, they don’t specifically boost how well the product sticks to the surface, which is the main job of stickers.
