Which method is used to deposit pesticide directly onto target plants?

• A. Rope-wick
• B. Fogging
• C. Soil injection
• D. Granular spread

Answer: (A)

Direct deposition on plant tissue comes from methods that place the chemical right onto the plant itself. Rope-wick uses a soaked wick that is kept in contact with the plant surface, delivering the pesticide directly to the target area such as the canopy, stem, or trunk. This focused placement helps ensure the pest encounters the product where it feeds or shelters, with less drift than other methods. Fogging applies a fine mist into the air, so the chemical settles broadly on surfaces rather than being placed precisely on the plant. Soil injection delivers the pesticide into the soil around the roots, not onto above-ground tissue. Granular spread scatters granules on the soil surface, with most movement into the soil or through weathering before reaching the plant tissues.
