Product Application of Aluminum phosphide (CAS#20859-73-8)
Aluminum phosphide (AlP) is primarily utilized as a fumigant for controlling insects and rodents in both food and non-food crops within indoor settings. Additionally, it is employed outdoors for rodent management through applications in burrows or grain storage areas. Owing to its widespread use in safeguarding rice crops, the compound is colloquially referred to as "rice tablet" in certain regions.
AlP is available in solid formulations, including tablets, pellets, or dust, catering to diverse application requirements.
