The Crop Disease Au application has been developed by the Australian National Variety Trials program (NVT) and funded by the Grains Research and Development Corporation GRDC). It provides quick access to current disease resistance ratings, disease information and an extensive disease image library. Compare the resistance ratings of wheat, barley, canola, chickpea, faba bean, field pea, lentil, lupin, oat and triticale for a range of different diseases. Compare disease symptoms with photographs and access detailed descriptions of each disease with management controls. Explore detailed information on crop varieties, map diseases, and automatically share photographs with friends or colleagues via email.With live feeds from the Australian National Variety Trials (NVT) database, variety information will always be up to date and information on newly released varieties will become instantly available upon their release. The disease resistance ratings presented in the app are developed in collaboration with with a working group of pathologists from state-based departments, universities and private consultancies funded by GRDC. The disease ratings used in this app can also be found on the NVT website (www.nvtonline.com.au) and in the sowing/variety guides developed by the state-based departments of agriculture and primary industries.
