Flonicamid Metabolite TFNG is primarily involved in plant protection as an active component derived from the insecticide flonicamid. It acts as a feeding blocker in sap-sucking pests such as aphids, whiteflies, and planthoppers by disrupting their ability to ingest plant sap. This effect leads to rapid cessation of feeding, resulting in pest control and reduced transmission of plant viruses. Due to its selective mode of action and low impact on beneficial insects like pollinators and natural predators, TFNG contributes to integrated pest management programs. It is commonly used in agriculture on crops such as vegetables, fruits, and ornamentals, especially where resistance to other insecticides has developed. Its systemic activity allows it to be effective when applied through soil drenches or foliar sprays, providing flexible use in various growing systems.
