2. Database, including cereal rust collection and rust surveys, set up ca. 15 years ago In recent years, demand for rapid notification of results has increased In the past 2 years, Dr Wellings has done this manually Dr Nabil Ahmad (PBI) kindly restructured the database in FileMaker Pro, early 2011 All samples received for pathoytping are now acknowledged, and results sent as soon as they are generated, by email Pathogenicity surveys, rust database

3. 375 samples received to date, 8 from artificially inoculated material Wheat stem rust Common in commercial wheat crops in south eastern Australia Found on Yitpi volunteers in the Mallee in late February 2011 60 samples received, 4 pts identified: 34-2,12,13 (nNSW, 3 isolates) 34-2,12,13 +Sr21 (nNSW 1 isolate) 34-1,2,7 +Sr38 (45 isolates) 34-1,2,7 +Sr38 [Yalta Low] (6 isolates) Pathogenicity surveys, 2004 - 2010 - number of samples received and processed Year Pathogen2005200620072008200920102011* WSR511252118116021 WLR1224013231910029 WYR393167350830552650253 BLR273113656212319 BSR10 451852 OCR463424491716530 OSR41171342209413 Total6904244381,0327051,197367 * As at 26 September 2011
