About the research project

Potato industries often rely on prophylactic pesticide applications for control of soil-borne disease. This is largely in absence of a good understanding of the dynamics of disease development. Disease predictive tools provide growers with a decision support system that would enabling most efficient use of interventions to improve disease control and productivity.

This PhD will:

Generate a deep understanding of the dynamic drivers of disease development for two key soil-borne diseases (powdery scab and pink rot) and use this information to develop predictive and monitoring systems for these diseases in situ. A new predictive system will focus on key parameters of the disease triad in its development, integrating measurements of:

  • Pathogen (including initial inoculum inputs from soil and seed tubers and population development in soil and plant tissues),
  • Host (including real-time measurement of root function through hydrological conductivity assessment and spectral crop monitoring), and
  • Environment (including rainfall, air temperature monitoring, EMS soil mapping, soil monitors for soil moisture and temperature).

In addition to contemporary control of the target diseases, the models will have value in assessment of the likely impact of climate change, by enabling modelling of changes in air and soil temperature and rainfall, and for preparedness for novel pathogen incursions providing a suitable base to estimate likelihood of impact of such an incursion.

This PhD will work within a dedicated internationally renown potato pathology research team in collaboration with researchers and support personnel from Simplot, a major international potato industry partner. The project may require international travel to work with collaborators in the US.
