Aluminium phosphide

Aluminium phosphide is a highly effective active ingredient classified under the metal phosphide chemical group. In agricultural practice, it is exclusively utilized as a powerful fumigant designed to eradicate insect pests and mites within enclosed environments, such as grain silos, warehouses, and shipping containers.

The mechanism of action is based on a chemical reaction triggered by atmospheric moisture. When the tablets or pellets come into contact with humidity, they release phosphine (PH3) gas. This gas possesses exceptional penetrative properties, allowing it to permeate through bulk grain or dense commodities to reach and eliminate pests at all life stages, including eggs, larvae, pupae, and adults.

This substance is widely employed to protect stored cereals, pulses, oilseeds, and processed agricultural goods. It is particularly effective against major stored-product pests such as the grain weevil, lesser grain borer, flour beetle, and various species of moths that can cause catastrophic losses in stored inventories if left unchecked.

• Strict requirement for site sealing to maintain gas concentration.
• Recommended application temperature is above 10°C for optimal gas release.
• Specific exposure times are necessary to ensure complete pest mortality.
• Safe handling protocols for residues after the fumigation process.

Handling aluminium phosphide requires strict adherence to professional safety protocols, as it is categorized as a highly toxic substance. It must never be used in residential areas. Only trained and certified personnel should conduct fumigation. After the required exposure period, the facility must be thoroughly ventilated and monitored to ensure that phosphine gas levels have returned to safe, non-detectable levels before human re-entry.
