Description

Fipronil is a broad-spectrum phenylpyrazole insecticide and acaricide known for its high efficacy at low application rates. Its primary value lies in its unique mode of action, targeting the insect GABA-gated chloride channel, which makes it a critical tool for resistance management in integrated pest control programs. This product is essential for manufacturers in the agricultural, professional pest management, and veterinary pharmaceutical industries seeking reliable, high-quality active ingredients for their formulations.

Application

• Agricultural Insecticides: Formulated for crop protection against a wide range of pests including soil insects, borers, and foliar feeders in cereals, corn, and rice.
• Professional Pest Control (PCO): Used in baits and sprays for the control of cockroaches, ants, termites, and other structural pests.
• Seed Treatment: Applied to seeds to protect against early-season soil and sucking pests, promoting healthy crop establishment.
• Veterinary Pharmaceuticals: A key active ingredient in topical spot-on solutions, sprays, and collars for controlling fleas and ticks on pets and livestock.
• Public Health: Incorporated into products for controlling disease-vector insects such as mosquitoes and locusts.
• Non-Crop Uses: Employed in turf management and for the protection of stored products.
