A mobile apparatus (10) is provided for the on-site production of phosphine fumigant gas so as to permit selective delivery over time of essentially constant concentration phosphine gas, thereby assuring complete fumigation of a grain silo or other enclosure. The apparatus (10) includes a mobile frame 12 supporting a reactor assembly (14); the latter includes an elongated stirred reactor (16) with metal phosphide and reactant gas (carbon dioxide and water) inlets (18,20) and a phosphine gas output (22).
