10 David Schlipalius 2011 Diagnostic technologies for phosphine resistance management - Final Report 18 <p>Phosphine is an inexpensive, versatile fumigant, accepted on world markets as a residue-free treatment. It is relied on heavily throughout the Australian grain industry to maintain freedom from insect infestation - an important aspect of grain quality for export markets.</p> <p>Research spanning many years has not identified a suitable alternative for phosphine. This has placed pressure on efforts to maintain phosphine by minimising the development and spread of phosphine resistance among grain insects.</p> <p>In order to contribute to the management of phosphine resistance, this project set out to determine the feasibility of developing a molecular diagnostic test for phosphine resistance.</p>
