  • Applications

    Aluminum Phosphide (CAS 20859-73-8) is primarily used as a fumigant pesticide for stored-product protection in agriculture, releasing phosphine gas when exposed to moisture to control insects, mites, and other pests in grains, legumes, and other dried commodities. It is commonly applied on site for fumigation in warehouses, ships, and containers to safeguard bulk goods throughout logistics and storage. As a source of phosphine, it is often employed for quarantine and transport treatments of agricultural products. It may also be used to fumigate wood packaging materials and other bulk commodities to meet import/export quarantine requirements. In industrial settings such as food processing facilities and storage warehouses, it supports pest control programs under appropriate handling protocols. Use is subject to local regulations and safety guidelines.
