An application device that rubs the herbicide on the leaf surface is:

• A. Wiping applicator
• B. Sprayer
• C. Roller applicator
• D. Foam applicator

Answer: (A)

Rubbing herbicide onto the leaf surface is done with a wiping applicator. This method uses a cloth, pad, or sponge saturated with herbicide and physically rubs it across the leaf to deliver the chemical directly to the surface. It allows precise, localized treatment with minimal drift compared to spraying, making it ideal for spot treatments or sensitive crops. Other devices rely on different mechanisms: a sprayer disperses droplets over the foliage, a roller applicator transfers the chemical by rolling a wetted roller against the leaf, and a foam applicator applies herbicide in foam form rather than by rubbing.
