  • Applications

    Imidacloprid (CAS 138261-41-3) is a systemic neonicotinoid insecticide widely used in agriculture to protect a broad range of crops from sucking and chewing pests. It is commonly applied as seed treatment, soil drench, or foliar spray to provide internal protection for the plant. In addition, it is used in professional pest management for termite control and is formulated for residential garden and lawn products to control common pests such as aphids, whiteflies, and beetles. In ornamental horticulture and turf management, it helps maintain landscape appearance and plant health.
