Under the new NVT Pathology Services Agreement 2019–23, the total number of diseases and crop species being screened in NSW has increased. Eight different crop types, both cereal and broadleaf, are annually screened for a total of 17 different diseases across three climatically and agronomically diverse sites within NSW (NSW DPI research stations based at Grafton, Tamworth and Wagga Wagga).
• Yearly screening is required to quantify and monitor the reaction of current and new varieties to diseases of economic importance.
• Natural changes in virulence occur in pathogen populations or when exotic pathotypes are introduced to Australia. These can affect host plant (variety) resistance ratings in both cereal and broadleaf crops.
• Five wheat stripe rust pathotypes of significance were detected in the NSW cropping regions during 2020; four were present in NSW Department of Primary Industries (NSW DPI) stripe rust nurseries.
• Host resistance can vary significantly depending on the stripe rust pathotypes present.
• Growers and advisers are kept up to date with latest resistance ratings each year through nationally co-ordinated National Variety Trials (NVT) pathology trials across a wide range of crops and diseases.
