What is the term for a sticker designed to hold the active ingredient on the sprayed surface?

• A. A sticker
• B. Dusts
• C. A penetration agent
• D. Emulsion

Answer: (A)

The key idea is how adjuvants help the spray stay on the target surface. A sticker is an adhesive-type adjuvant that forms a thin film on leaves or other surfaces, helping the active ingredient cling and resist being washed off by rain, dew, or irrigation. This keeps more of the product in contact with the target and can improve effectiveness, especially on smooth or waxy surfaces. Dusts refer to dry powders that can aid coverage but aren’t specifically about sticking the product to the surface. A penetration agent helps the chemical move into plant tissue rather than stay on the surface. An emulsion is a two-phase liquid formulation, not the function of sticking to surfaces.
