Application of a pesticide to the stem, leaves, needles, or blades of a plant is called what?

• A. Foliar Application
• B. Soil Injection
• C. Seed Treatment
• D. Basal Bark

Answer: (A)

Foliar application is applying pesticide directly to the plant’s foliage—grass blades, leaves, needles, or similar above-ground parts. This method targets pests that feed on or contact the surfaces of the plant and often allows rapid absorption through the leaf cuticle for quick or systemic control. It’s different from other methods like soil injection (into the soil to reach roots), seed treatment (coating seeds before germination), or basal bark (application around the base of a tree trunk). Because the question describes applying to the stem, leaves, needles, or blades, it fits foliar application perfectly.
