Foliage application is application to the leaves of growing plants as mists or sprays.

• A. application before planting.
• B. application to the leaves of growing plants as mists or sprays.
• C. application to roots of plants.
• D. application to soil surface.

Answer: (B)

Foliar application means delivering substances directly to the leaves of growing plants by spraying or misting, so they come into contact with the foliage rather than the soil or roots. This method targets the above-ground parts and allows relatively quick absorption through the leaf cuticle and stomata, making it useful for providing nutrients or pesticides when rapid uptake is needed. The other options describe different targets or timings: applying before planting is a pre-plant treatment, applying to the roots targets the root zone, and applying to the soil surface addresses soil- or root-area treatments. Since foliage application is specifically about the leaves and the spray/mist method, it is the best description.
