Description

α-Cypermethrin is a potent synthetic pyrethroid insecticide known for its high efficacy and broad-spectrum activity. This product is critical for professional pest management, offering rapid knockdown and long-lasting residual control. It is essential for agricultural producers, public health programs, and professional pest control operators seeking reliable solutions for crop protection and vector-borne disease prevention.

Application

• Agricultural Pest Control: Effective against a wide range of lepidopteran, coleopteran, and dipteran pests in crops such as cotton, fruits, vegetables, and cereals.
• Public Health Vector Control: Used in mosquito control programs for the management of malaria, dengue, and other mosquito-borne diseases.
• Structural Pest Management: Applied by professional exterminators for the control of cockroaches, ants, flies, and other crawling and flying insects in residential and commercial buildings.
• Stored Product Protection: Protects grains and other stored commodities from infestation by beetles, moths, and weevils.
• Livestock and Animal Health: Used in ectoparasite control for livestock, including ticks, lice, and flies on cattle, sheep, and poultry.
• Termite Control: Employed as a soil treatment for pre- and post-construction termite barrier systems.
