  • Applications

    Alpha-Cypermethrin (CAS 67375-30-8) is primarily used as an insecticide in agriculture to protect crops from pests and to control insects in field and greenhouse settings; it is formulated in common product forms such as EC, WG, and granules for field spraying, crop protection, and stored-product protection. It is also used in consumer and professional pest-control products for households and exterior areas, in formulations such as sprays, dusts, or granules. In public health vector control programs, the pyrethroid is used to reduce nuisance and disease vectors such as mosquitoes. It is also employed for wood protection and wood treatment against termites and other wood-destroying organisms, as well as for protecting stored commodities from pests during storage. Common agricultural applications include field crops, greenhouse crops, and stored-product protection; all usage is subject to local regulations and formulation limits.
