GENERAL INFORMATION Click here for an explantaion of the general chemical status information
for phosphine

Description: The major uses of phosphine are as a fumigant during the storage of agricultural products and against vertebrates. Often generated via the breakdown of other substances such as aluminium phosphide.

Example pests controlled: Bean weevil; Fruit moth; Grain beetle; Meal moth; Tobacco moth; Meal worm; Leaf beetle; Flour beetle; Pink bollworm; Maize weevil

Example applications: Stored grain; Stored animal feed; Leaf-stored tobacco; Cotton seed
