This project is designed to explore and test a range of management practices with the aim of making some practical recommendations for growers and the grains industry to enable them to better manage mice, without having to rely on applications of zinc phosphide. Through a series of ten sets of replicated experiments across the three regions (North, South and West), we will evaluate the impact of these practices on mouse populations, but also evaluate the economics of the practices and the impact on profitability of growers. There will be a strong communications effort to enable growers to understand the economic thresholds of mouse populations including management practices.
