Product Overview
PH3® is a restricted-use aluminum phosphide fumigant used for labeled stored commodity fumigation, transport fumigation, and certain burrow applications.
When exposed to atmospheric moisture, PH3 releases phosphine gas, a true fumigant gas that penetrates properly sealed commodities, structures, transport containers, and burrow systems to control listed pests according to the product label.
PH3 is commonly used in stored grain, seed storage, animal feed, milling, warehouse, railcar, container, export, and commodity storage fumigation programs. It is also labeled for certain burrowing pest applications when used according to the product label and applicator manual.
PH3 is available in pellet and tablet formulations. Pellets release phosphine faster and are often used where faster gas generation is needed. Tablets release phosphine more slowly and may be preferred when a slower release profile is desired. Product selection should be based on the fumigation plan, commodity, temperature, structure, exposure period, burrow conditions, and label directions.
