Product Overview
Magnaphos® is a magnesium phosphide fumigant designed for quick, reliable release of phosphine gas in low temperature or low humidity conditions. Because it is formulated without ammonium carbamate, Magnaphos plates do not release ammonia, making them ideal for sensitive commodities such as fresh produce and stored tobacco. This versatile fumigant provides powerful protection against major stored grain pests, including moths, beetles, and weevils, while leaving no residue behind.
