Integrated Disease Management (IDM) using various combinations of cultural, fungicide and resistance strategies offer the most viable long-term option for controlling the significant field crop diseases in the Northern Region. This project aims to build on the advances in IDM of major summer and winter crops made in the GRDC-funded project DAQ00154.
Soil-borne diseases cause significant and often unexpected yield losses in broadacre crops. Annual potential national losses in wheat from soil and stubble-borne pathogens have recently been estimated to exceed $1,060 million and $792 million, respectively. Most decisions to minimise the risk from soil-borne disease need to be made before seeding, but determining which diseases pose the greatest risk can be difficult, as pathogen levels respond to changes in climate variability, farm practices, cropping sequence and crop varieties. This project provides new tools to help growers reduce the losses due to soil borne diseases.
Models will be developed using up-to-date research findings and the best scientific procedures. Before the models are applied they will be tested with location-specific data. After testing they will be used to make decision-aiding tools to assist with farm management. The decision tools will be field tested with groups of potential users across the country.
This project will result in improved decision making for management of disease in cropping resulting in improved profitability and reduced financial risk for Australian grain growers.
