Alternatives to Phosphine - Final Report

The use of nitrogen as a method for grain storage has been known for more than 30 years but only recently with the development of lower priced Pressure Swing Adsorption (PSA) and Membrane Separation (MS) Nitrogen generators, has it been possible to consider the technique as a viable grain protection system. This project successfully developed clean high nitrogen technology at a commercial scale for offering an immediate answer to the growing problem of insect resistance to phosphine and satisfies growing market demand for grain free of pest and chemical residues.
