Completing the Picture: Integrating Plant Disease Into Ag Systems Modelling

I present four scenarios that cover various spatial and temporal scales where plant disease models can be used to help inform growers or researchers. This was presented for the official opening of the USQ Agriculture Systems and Engineering Precinct in Toowoomba as a part of a symposium on the future of agriculture.
