Roadmap for a Regional Agri-Food Knowledge Cluster in North West Tasmania (2022)$38,636
This project will create a regional agri-food knowledge cluster in North West Tasmania. The cluster will link family farms and local agri-food enterprises with regional knowledge enterprises (e.g. researchers, digital experts), equipping them with the tools and resources to work together to strengthen drought resilience. The cluster will support local producers to navigate the fast-changing landscape of knowledge-intensive agriculture and food technologies and identify, adopt and adapt relevant new technologies to transform profitability and sustainability along the value chain. This will enable producers to diversify, mitigate against risk and generate cross-cutting economic, social and environmental benefits for the region (Objective 4a), as well as concrete benefits for agricultural productivity (1b) and community wellbeing (3a). The Ideas project will co-design the cluster, identify key opportunities for cross-sector collaboration and investment and produce a roadmap of next steps.

Development of regional risk models for fungal diseases in pyrethrum (2021 - 2023)$516,923
Disease management in pyrethum is a major concern. Diseases such as ray blight and tan spot represent a major risk to yield and the industry's ability consistently meet market production requirements. Managing that disease also represents a major financial and environmental cost. Therefore, any effort to reduce these costs without major disease yield losses would be beneficial.Currently, a standard industry wide recommended spray program is deployed to manage disease. However, anecdotal evidence from growers and initial results obtained from previous studies suggests that different growing regions are subject to different levels of disease pressure. It is suggested that if the relative risk of disease is quantified across the different growing regions, disease control strategies could be refined for the different regions. This would lead to an overall reduction in control costs by reducing fungicide sprays in low risk regions, whilst ensuring high risk regions are subject to sufficient sprays to mitigate disease losses. This reduced level of fungicide inputs would also help the industry minimise the spread of fungicide resistance in the fungal pathogen populations, an issue that is of increasing importance.This project aims to develop a risk framework for the pyrethrum industry that can be used to adapt their disease management strategies in accordance with region and environmental conditions. It is also envisaged that this work will lead to at least 3 Q1 research publications.
