Description

Fenvalerate is a synthetic pyrethroid insecticide known for its broad-spectrum activity and photostability. It is a critical active ingredient for controlling a wide range of insect pests in agricultural and public health applications. This product is essential for formulators and manufacturers in the crop protection, animal health, and vector control industries seeking effective and reliable pest management solutions.

Application

• Agricultural Insecticide: Formulated for the control of lepidopteran, coleopteran, and other pests in crops such as cotton, fruits, vegetables, and cereals.
• Public Health: Used in the formulation of products for mosquito control and the management of other disease-carrying insects.
• Animal Health: Incorporated into ectoparasiticide products for livestock and pets to control ticks, lice, and fleas.
• Stored Product Protection: Applied to protect grains and other stored commodities from insect infestation.
• Termiticide: Used in soil treatment and wood preservation formulations for termite control.
• Household Pest Control: A key component in insecticide sprays, coils, and other products for domestic use.

Quality Control

Our Fenvalerate is manufactured under a strict quality management system to ensure batch-to-batch consistency and compliance with FAO and WHO specifications. Each lot is analyzed for identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing assay, isomer content, and relevant impurities is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability.
