Aluminum phosphide is a highly toxic inorganic compound with the chemical formula AlP, which is mainly used for killing and preventing insects in food storage. It decomposes by absorbing water in the air to produce highly toxic phosphine gas, which has an efficient killing effect on insects. Because of its low cost and high efficiency, aluminum phosphide is widely used in rural areas. The use of aluminum phosphide needs to strictly abide by the safety operation procedures to prevent the occurrence of poisoning accidents. Specifically, the uses and application scenarios of aluminum phosphide include:

‌ grain storage ‌ : aluminum phosphide is widely used in grain storage, especially for controlling grain storage pests. It can kill pests in stored grain by fumigation to ensure the safe storage of grain.
‌ Other storage materials ‌ : aluminum phosphide is also used for the insecticidal work of rape seeds, feed, medicinal materials, tobacco, tea, paper and other storage materials, by decomposes phosphine gas produced to kill pests in these materials.
When using aluminum phosphide, the following points need to be noted:

‌ safety ‌ : aluminum phosphide is highly toxic, accidental inhalation or contact may lead to poisoning and even death. Therefore, it must be used in strict accordance with safe operation procedures.
‌ Storage conditions ‌ : aluminum phosphide will hygroscopic decomposition under wet conditions to produce highly toxic phosphine gas, so it must be stored in a dry environment to prevent accidental poisoning.
‌ Protective measures ‌ : When using aluminum phosphide, wear protective equipment, such as gas masks, and ensure that the working area is well ventilated to reduce the risk of poisoning.
In summary, as a broad-spectrum fumigation insecticide, aluminum phosphide has a wide range of applications in agriculture and storage, but its high toxicity requires users to take strict safety measures.
