About the research project
Pyrethrum is a major horticultural crop in northern Tasmania. The Australian pyrethrum industry, the majority of which is situated in Tasmania, is the largest supplier of the natural insecticides, pyrethrins, into the world market. 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 results obtained from previous studies suggests that different growing regions are subject to different levels of disease pressure. Additionally, the impact of fungal diseases on crop yields is highly dependent upon climatic conditions. It is suggested that if the risk of negative disease impacts is quantified relative to environmental conditions, disease control strategies could be refined for implementation the target control strategies. This would lead to more effective and efficient fungicide applications, and an overall reduction in control costs by reducing fungicide sprays.
This project will investigate the effect of environmental factors such as temperature, moisture and light on disease outbreaks. The components that drive disease outbreaks include, fungal growth, sporulation, plant host infection and host colonisation. How the environmental conditions impact each of these components individual and/or as a system will be key questions for this project. The work undertaken in this project will support a larger, Hort Innovation supported project, that aims to develop risk models and decision systems for the Australian pyrethrum to provide improved disease management strategies for the industry.
