Which term is designed to hold the active ingredient on the sprayed surface?

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

Answer: (A)

A sticker is a film-forming adjuvant added to spray solutions to help the active ingredient stay on the plant surface. It creates a sticky, clingy layer that adheres droplets to the leaf, increasing retention time and reducing wash-off from rain, dew, or wind. This makes the active ingredient more likely to stay where it’s needed long enough to work. Dusts are powders that can aid coverage or act as carriers, but they’re not meant to keep the active ingredient attached to the surface. A penetration agent aims to move the active ingredient through the leaf cuticle into the plant or pest, which is about entry rather than surface retention. An emulsion is a type of formulation where droplets of one liquid are dispersed in another; it describes how the product is mixed, not specifically how well it sticks to the surface.
