Due to their characteristics, formulations based on magnesium phosphide (Mg3P2), are the fumigant of choice for quick fumigations even under suboptimal conditions. Mg3P2 is created by the fusion of magnesium and yellow phosphorus. In contact with ambient air and humidity the very efficient phosphines gas is developed and released.
Pellets contain of 66% inert magnesium phsophide as active substance and 34% inert components, mainly ammonium carbamate amongst others, that facilitate controlled outgassing of phosphine.
One pellet has a weight of 0.6 g and releases 0.2 g phosphine gas.
Round Tablets contain of 66% inert magnesium phosphide as active substance and 34% inert components, mainly ammonium carbamate amongst others, that facilitate controlled outgassing of phosphine.
One round tablet has a weight of 3 g and releases 1 g phosphine gas.
Plates / Strips
Plates and strips contain of 56% magnesium phosphide as active substance and inert components that facilitate controlled outgassing of phosphine. This formulation does not contain ammonium carbamate.
The formulation is integrated in a flexible plastic matrix, coated with special paper that is permeable to water vapour.
One plate has a weight of 117 g and releases 33 g phosphine gas. One strip contains of 20 Plates in a chain/strip, has a weight of 2,340 g and releases 660 g phosphine gas.
