LAST SUPPER MOUSE BAIT
(Broadacre Zinc Phosphide)

Mice plagues during the seasons of 2010-2014 throughout the southern grain belt saw farmers seeking more economically viable mice control options. Wilchem Pty Ltd in partnership with 4 farm-based manufacturing plants brought Last Supper Zinc Phosphide (Broadacre) Mouse Bait to market in 2014. The initial production of un-sterilised wheat based Zinc Phosphide bait gave farmers a reliable mice control option at less than one third of the cost of previously available products on the market. In 2021 a new double strength option “Last Supper Supreme 50” has been added to the product range in un-sterilsed, sterilsed and pellets.

Emerging pest resulting from conservation farming practices

The shift towards no till and stubble retention farming systems throughout the southern Australian grain belt has seen significant yield improvements for farmers. These conservation farming methods however have also resulted in favourable habits for a new spectrum of pest including mice, snails and slugs. In order to control these new pests, farmers are implementing Integrated Pest Management practise which are seeing them use a variety of tools including mechanical (strategic tillage, cabling, rolling), crop rotation, strategic burning and chemical baiting to combat the evolving issues.

About Zinc Phosphide
Mouse Bait

Zinc Phosphide (ZP) was first used to control mice in Australian broad acre farming systems under emergency permit in 1997 before achieving registration in 2000. Zinc Phosphide has become the preferred rodenticide for broad acre mice control as it is: well accepted by rodents, does not leave residues in crops or the environment and has low impact on secondary non-target species. The standard formulation for Zinc Phosphide mouse bait is 25g Zn3P2/kg which equates to 1 mg of ZP per grain of wheat bait. This formulation means a single grain provides the lethal dose to an adult mouse. In 2021 a new double strength option of 50g Zn3P2/kg called “Last Supper Supreme 50” has been added to the product range in un-sterilsed, sterilsed and pellets.

Current Last Supper Products Available

Since the initial offering of only un-sterilised ZP bait in 150kg drum in 2014, the Wilchem product range of Last Supper Zinc Phosphide has expanded with the assistance of its manufacturing partners, like Their Last Supper Pty Ltd (trading entity for mouse bait at AG Schilling & Co). In 2021, the standard 25g Zn3P2/kg formulation is still available but Wilchem is now able to offer customers a double strength option of 50 Zn3P2/kg called Last Supper Supreme 50. Both options are available as sterilised and un-sterilised wheat based baits in packaging sizes of 150kg drums and 500kg plastic lined bulk bags and pellets in 500kg bulk bag.
