Phosphine is central to pest management in the Australian grain industry and its continued effectiveness is essential to the sustainability of grain biosecurity and market access for Australian grains. In the past 10-15 years, resistance to phosphine in target insect pests has increased in both frequency and strength such that it now threatens effective control.
In response, this strategy was developed in consultation with the Australian grain industry to ensure that practical and commercial constraints inherent to this industry were accommodated without loss of the resistance management aim. The strategy applies to all sectors and is consistent with current best practice integrated pest management. However, the strategy is voluntary, and success will depend on industry commitment and widespread compliance. Where successful, these strategies will limit the spread and impact of resistance but not eradicate it.
