Imidacloprid is widely used as a systemic insecticide in agriculture and veterinary practices. It is effective against a broad spectrum of sucking insects such as aphids, whiteflies, thrips, and leafhoppers. Applied to soil, seeds, or foliage, it is absorbed by the plant and distributed through the vascular system, making the entire plant toxic to pests. It is commonly used in crops like cotton, rice, vegetables, and fruits. In addition to agricultural use, imidacloprid is used in household pest control products and veterinary medicine to control fleas and other parasites on pets. It is often found in spot-on treatments and oral formulations for dogs and cats. Due to its high potency and systemic action, it provides long-lasting protection with relatively low application rates. However, its use has raised environmental concerns, particularly regarding non-target insects such as bees, leading to restrictions in certain regions to protect pollinator populations.
