PHD POSITION – Pest and disease modelling in grain cropping systems

Understanding pest and disease dynamics within farming systems and the ability to relate incidence and seasonal conditions to grain yield loss is a clear and present challenge for the agricultural science community. Currently, management of many pests, diseases and weeds in crops relies on an estimated economic damage threshold. The threshold is used to help identify when a pest population should be reduced to prevent yield loss.

However, this approach does not consider the environment, the timing of pest control in relation to crop development, the pest lifecycle or the economic cost to future crops. Further, in many farming systems, the decision to control a pest or disease outbreak is required before the economic threshold is reached, in which case identifying and forecasting drivers for epidemics can support and improve the outcomes of pest and disease control decisions.

In contrast to traditional reactive approaches, this project will develop a proactive forecasting approach, providing end-users with the ability to plan and holistically manage pest populations well before any economic damage thresholds are attained.

Funding
