Researchers are requesting industry to submit field pea samples infected with bacterial blight from all pea growing regions. This survey will help researchers understand the prevalence of the pathovars within the pathogen population.
Bacterial blight disease in field pea is caused by the bacterial pathogen, Pseudomonas syringae. There are two pathovars, pv.syringae […]

Diagnosing plant diseases: What do we ask and why do we ask for it?

Diagnosing a plant disease or other injury is like going to a medical doctor who must ask several questions before making an accurate diagnosis and recommending a treatment. If you withhold information, it can lead to a misdiagnosis. The same goes for crop diseases. Plant pathologists, specifically diagnosticians, are often […]

Blackleg Management Guide

Blackleg lesions on canola leaf

After a bumper season in 2017 Victorian growers are reminded to be proactive in monitoring and management of barley diseases. Mark McLean, Barley Pathologist with Agriculture Victoria spoke to us at the Bendigo GRDC Updates and gives growers a heads up of what diseases are likely to pop up in […]

Top 3 diseases to watch for fungicide resistance

Figure 1. A) Barley net form of net blotch, B) barley powdery mildew and C) Wheat powdery mildew have been highlighted in the 2016 Fungicide Resistance Group sampling report.

Three key fungicide resistance findings from the 2016 growing season remind Australian growers to stay vigilant when it comes to monitoring crop disease.
These are findings of the annual sampling report by the Fungicide Resistance Group, a program within the Centre for Crop and Disease Management, co-supported by Curtin University and […]

Lupin growers to keep an eye out for Lupin anthracnose

In the eastern Riverina region of NSW in October 2016 lupin anthracnose was detected for the first time in commercial crops. The disease is present in WA and SA but still remains a notifiable exotic disease in NSW and Victoria. Natural hosts of lupin anthracnose are not established in NSW […]
