Nitrogen (N2) based atmosphere has been re-evaluated as cheaper, reliable and high efficient nitrogen generators (PSA – Pressure Swing Absorption and MNS – Membrane Nitrogen Separator) are available for grain industry. The systematic laboratory bioassay were conducted on four species of mixed-age cultures of Sitophilus oryzae (L.), Tribolium castaneum (Herbst), Rhyzopertha dominica (F.) and Trogoderma variabile (Ballion) in five representative grains (wheat, barley, oats, Lupine and canola), and adult stages of Ladybird and Bronzed field beetle (Adelium brevicorne) in canola at 95-99% N2 and 25-35ºC for 1 day to 4 weeks exposure. The techniques were tested on farmer storage using farm bins - Lake Grace (33°06’00”S 118°27’40”E) and Cooperative Bulk Handling Albany export terminal (35°1’50.90”S 117°53’10.54”E). This research 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.
