Description

β-Cyfluthrin is a potent synthetic pyrethroid insecticide known for its high efficacy and broad-spectrum activity. This compound is critical for providing reliable, long-lasting pest control solutions in demanding agricultural and public health environments. It is primarily needed by manufacturers of professional pest control products, agricultural formulators, and public health programs targeting a wide range of insect pests.

Application

• Agricultural Insecticides: Formulated for the control of chewing and sucking insects in a wide range of crops including cotton, cereals, fruits, and vegetables.
• Public Health Pest Control: Used in products for the management of mosquitoes, flies, cockroaches, and other disease vectors in residential and commercial settings.
• Professional Pest Management (PM): A key active ingredient in formulations for structural pest control, termite prevention, and turf & ornamental pest management.
• Animal Health: Incorporated into ectoparasiticide products for livestock and pet care to control ticks, fleas, and lice.
• Wood Preservation: Used in treatments to protect timber and wood products from wood-boring insects.
• Stored Product Protection: Applied to protect grains and other commodities from infestation during storage.
