Which term describes the application to the leaves of a plant, shrub, or tree?

• A. Foliar
• B. Pour on
• C. Band
• D. Over-the-top

Answer: (A)

Applying to the leaves is described as foliar. When a product is sprayed onto the foliage, it’s absorbed directly through the leaf surface for relatively quick uptake, which is useful for fast correction of nutrient deficiencies or rapid pest control. This distinguishes it from methods aimed at the soil or trunk areas: pour-on is not used for plants (it's a term from animal applications), band refers to a narrow strip placement often along the soil or row, and over-the-top describes spraying over the top of the canopy. So the term that best fits leaf application is foliar.
