Used as a systemic insecticide in agriculture, imidacloprid solution is applied to control sucking insects such as aphids, whiteflies, and leafhoppers on crops like cotton, cereals, vegetables, and fruits. It is effective when applied through soil drenching, seed treatment, or foliar spray, as it gets absorbed into plant tissues and kills pests upon ingestion. Commonly used in both field and greenhouse settings, it provides long-lasting protection due to its stability and translocation within the plant. Also utilized in urban pest management, it helps control termites and other structural pests when applied as a soil treatment around buildings. Its high potency at low application rates makes it a preferred choice in integrated pest management programs.
