Growers and advisors will need to remain vigilant and monitor crops closely for the presence of Russian wheat aphid (RWA), particularly in the Wimmera/Mallee region. Current reports indicate that RWA is widespread in the Wimmera and populations are becoming more evident in the Mallee. Russian wheat aphid has also been […]
Wheat leaf rust, barley leaf rust and wheat stripe rust have all been found in Victorian cereal crops. Growers and advisors are advised to inspect cereal crops for symptoms (Figure 1) and determine the need to apply foliar fungicides. Check the latest disease resistance ratings in the Victorian Cereal Disease Guide to identify varieties […]

Chickpea growers in South Australia are advised to apply preventative fungicide sprays in chickpea crops ahead of rain events for Ascochyta blight control and continue to monitor the disease after reports of disease on previously resistant varieties.
Following on from reports of severe […]
Lupin crops across Victoria’s lupin growing regions have been experiencing high levels of Sclerotinia collar rot (caused by Sclerotinia minor) causing main stem infections as a result of cool wet conditions conducive to the disease. Some crops have been badly affected, particularly in the Victorian Mallee where infection levels of […]
Growers in the Victorian Mallee are advised to apply early preventative fungicide sprays in chickpea crops for Ascochyta blight control and continue to monitor for disease after reports of Ascochyta blight on previously resistant varieties.
In 2015 an outbreak of Ascochyta blight in a Kabuli chickpea trial in the southern […]
A new genetic discovery from an Ethiopian landrace has potential to significantly improve resistance in barley to powdery mildew.
For the first time researchers at the Centre for Crop and Disease Management (CCDM) have found a gene that is resistant to all forms of powdery mildew, without affecting yield. The discovery […]
Scald has been detected in several early sown barley crops in the Wimmera and Mallee of Victoria. The disease has been favoured by wet seasonal conditions across the south eastern region and will be common in early sown crops and crops sown into barley stubble from 2014 and 2015. Scald […]
Recent wet conditions have favoured the development of sclerotinia stem rot in canola crops across south-eastern Australia. Growers need to consider their risk and enact a management strategy now to avoid yield loss later in the season.
Key considerations for management
High risk indicators for sclerotinia
A combination of the following risk factors […]
Management of the major mungbean diseases in Australia

For management of halo blight and tan spot: Plant seed with the lowest possible levels of infection, use varieties with higher levels of resistance, clean harvesting equipment, control weeds and volunteers, and […]
Early detection of powdery mildew in wheat in the Bindi Bindi region and south of Kadoux prompted the DAFWA team to present a webinar on powdery mildew in wheat and the implications for the 2016 season. This webinar was presented on July 6, 2016.
The key messages from the webinar were:
