Beyond the Bale : September 2014
46 ON FARM Timing of animal husbandry practices and treatments have a major impact on the flystrike risk, but weighing up the impact from each and the best time to do them can be a daunting task. However, FlyBoss tools make the job fast and easy. FlyBoss is a website developed by the Sheep CRC and its partners to provide producers with information and tools to improve flystrike management. With its sister sites, WormBoss and LiceBoss, it is now funded by AWI and Meat and Livestock Australia. The two FlyBoss tools that allow you to optimise your management and treatment strategies use your local long-term average weather data to calculate the risk of flystrike across the year. Results are displayed in a simple graph, and when each management practice (shearing, crutching and chemical treatment) is applied, the tool calculates any reduced flystrike risk and changes the graph accordingly. The tools are simple to use; they operate directly from the FlyBoss website, so there is nothing to download. After choosing your FLY TREATMENTS GETTING THE MOST FROM YOUR Flystrike preventative treatments could be wasted if not applied at the optimum time. Optimising treatment times is fast and easy with FlyBoss tools FlyBoss tools use your local weather data to map flystrike risk for your location. The graph indicates the average flystrike risk. Actual risk will vary greatly from week to week due to seasonal conditions. The maximum on the graph is set at the maximum risk for any management system tested in this session. EXAMPLE 1 COMPARE MANAGEMENT TOOL LOCATION Armidale, northern NSW (mulesed sheep) CURRENT MANAGEMENT Left column of table; red line in graph Shear first week of August, crutch mid-January, apply Dicyclanil 4 weeks later in mid-February. ADJUSTED MANAGEMENT Right column of table; blue line in graph Shear first week of August, no crutching, apply Dicyclanil in mid-November. The current management (red line) shows a high risk of flystrike, even with the sheep crutched. Whereas, the adjusted management scenario (blue line) shows the risk from flystrike is almost completely removed by changing the time of chemical treatment, even with the sheep not crutched (dag is not an issue in this area).
