Viruses and Sclerotinia are two disease threats that have come under increased scrutiny in New South Wales in recent years. Both can easily fly under the radar with symptoms that are often indistinguishable from those caused by abiotic stress and herbicides.

New research has identified three major resistance genes for blackleg in canola, developed markers, and is working to better understand how minor gene resistance is expressed. Screening shows that one of these major genes is present in most historic and many current Australian varieties.

The SARDI pathology group has supported growers with a disease diagnostics service for accurate identification, disease surveillance and disease management advice. Information has included the timing of spore showers and how shifts in disease pathotypes impact on variety resistance.

Ascochyta blight in chickpea has become more aggressive against commonly grown chickpea varieties such as PBA HatTrick (PBR), Genesis™ 090 and PBA Seamer (PBR). Studies into pathogen biology are targeting opportunities to develop better resistance and management recommendations.
