Dr Jason Scott is a research fellow in the Tasmanian Institute of Agriculture, within the College of Science and Engineering. His research focuses on studying diseases of agricultural crops. He is particularly interested in the epidemiology and population biology of fungal pathogens and using this information to aid the development of improved disease management strategies.

Biography

After completing his PhD, Jason worked as a postdoctoral fellow at CSIRO Plant Industry in Brisbane for 3.5 years. He then spent 18 months working at the University of Minnesota in St Paul, USA. In both of these positions his research was focused on the population biology of Fusarium pathogens of wheat.

Jason joined the Tasmanian Institute of Agriculture as a research fellow in late 2008. Since mid-2014, he has led the TIA plant pathology program based at the Cradle Coast campus. Research conducted within this group falls under four general areas:

  1. evaluating the risks posed to pyrethrum crops by new and emerging fungal pathogens
  2. understanding the mechanisms than influence how fungal pathogens evolve and adapt to agricultural practices
  3. evaluating the mechanisms of spread of downy mildew of poppies and how the disease is influence by environmental conditions
  4. modelling disease epidemics to better predict and manage their effects on crop yield

Jason also currently leads the Industrial and Extractive Crops working group with TIA’s Horticulture Centre.  This role helps facilitate research programs in this area both within TIA and collaboratively within the University of Tasmania

Research Themes

Jason's research aligns with the University's research theme of Environment, Resources and Sustainability. Diseases of agricultural crops present a large risk to growers and industry, and often necessitate economically and environmentally costly control strategies to manage those risks. The mechanisms that influence epidemics, including pathogen lifecycle, methods of dispersal, and environmental interactions, often give insight into how these diseases can be managed. By understanding these mechanisms, Jason aims to facilitate the development of alternative and more efficient disease management strategies, strategies that reduce the economic, social and environmental costs of production. In addition, by understanding the variation inherent within pathogen populations and their evolutionary potential to adapt, efforts can be made to ensure that management strategies remain effective into the future.

Jason's current research program into pyrethrum has shown that the disease tan spot has emerged as a significant issue for production, due in part from the pathogen having developed resistance to the existing chemical used for its control, rendering it ineffective and costly. This knowledge has allowed the industry to adopt new strategies to successfully control this disease, and maintain the economic and environmental sustainability of the industry.

Development of regional risk models for fungal diseases in pyrethrum (2021 - 2023)$516,923
Description
Disease management in pyrethum is a major concern. Diseases such as ray blight and tan spot represent a major risk to yield and the industrys 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.

Mechanisms and spread of fungicide resistance in pyrethrum fungal pathogens (2020 - 2023)$165,430
Description
Pyrethrum is an important part of cropping production in Tasmania, being grown for the natural insecticides pyrethrins. Diseases of pyrethrum are a major constraint on production in Tasmania caused by a complex of fungal pathogens. Management of these diseases requires the use of multiple applications of chemical fungicides each year. However, this exposes the industry to the risk of resistance building up within the pathogen population, reducing the efficacy of control leading to undesirable impacts on the economics and environmental sustainability of pyrethrum production.This project will focus on understanding the risk of fungicide resistance in key fungal pathogens of pyrethrum. Potential studies include looking into the genetic mechanisms that govern resistance, assessing the current extent of resistance present in field populations and evaluating the risk of resistance developing in the future. Answering questions associated with these issues will help the pyrethrum industry better manage fungicide usage into the future. As such, the project aims to produce impactful outcomes for Tasmanian agriculture.This project is to support a PhD candidate to be based at the CCC in Burnie. In conducting this project, the candidate will be supported by, and collaborate with, Botanical Resources Australia, the commercial operator of the Australian pyrethrum industry. The project will involve a combination of field-, glasshouse- and laboratory-based experimentation. Funds for operating costs and 50% of a co-funded PhD scholarship will be provided by BRA. The remaining 50% scholarship will be sought via competitive process within the TIA scholarship allocation.This intention for contracting of this project is to have the contract agreed upon and signed, but contract start and end to be timed with the start of a suitable PhD candidate.

Integrated disease management in pyrethrum (2017 - 2020)$748,195
Description
The Australian pyrethrum industry based in Tasmania and Victoria, accounts for over 50% of the world market for the natural insecticides, pyrethrins. An increasing number of foliar and flower diseases are significant constraints on production, reducing yield and the life span of perennial crops. The management of these involves significant inputs of chemical fungicides during production. However, costs and risks of fungicide resistance are increasingly recognised by the industry. This project aims to aid pyrethrum growers in minimising these issues by determining the dominant pathogens affecting the crop, the timing of their influence, and their susceptibility to key fungicides. This information will be used to optimise the number and timing of fungicide applications, and be combined with efforts to foster increased host resistance and reduce pathogen carryover between seasons. Ultimately, this will help the industry decrease its reliance on fungicides, reducing the economic and environmental costs of production, whilst increasing pyrethrum yields across the production region.

Improving the integrated management of pyrethrum diseases (2016 - 2017)$77,239
Description
The Australian pyrethrum industry is the world leader in the production of the natural insecticides, pyrethrins. The industry is based predominantly in northern Tasmania and is a key component of many cropping rotations employed by growers in the region. Commercial production is limited by several fungal diseases that are capable of having major impacts on crop yields. To manage this issues, the industry employs an extensive fungicide program, developed through close collaboration with TIA, over the life of the crop. However, the evolving nature of the pathogen population has highlighted concerns about the long term sustainability of such strategies. As such, the industry has shift its disease research priorities towards the integration of alternative strategies for disease control. Much of the ground work for such shifts were laid down by work conducted by TIA in the recently completed HIA funded project Integrated Disease Management in Pyrethrum. However, this work highlighted areas where further work is required. This proposed project aims to directly address these key questions that require further scientific study.

Understanding the evolution of fungicide resistance for durable control of fungal pathogens in pyrethrum (2013 - 2015)$407,888
Description
Fungicide resistance is an increasing global threat to agricultural productivity that has recently impacted the Australian pyrethrum industry, supplying 60% of the worlds natural insecticidal pyrethrins. The study of fungicide resistance is a severely neglected research area within Australia. Differential development of fungicide resistance in different fungal pathogens of pyrethrum provides a unique opportunity to: study the drivers of resistance evolution; determine the molecular basis of fungicide resistance; evaluate fitness costs to pathogens associated with resistance; clarify the role of dose rate in resistance development; and develop diagnostic tools for resistance monitoring and management.
