Crown rot in winter cereals -Western region

*Information on crown rot symptoms and management is available in the article Crown rot in winter cereals
During 2015 and 2016 there were low levels of crown rot in many wheat paddocks in the low to medium rainfall zones of WA. The severe level of disease experienced during the 2014 season […]

South Australia
In the main South Australian grain growing areas in 2017, crops generally established late or were sown early but did not receive follow-up rains for 4-8 weeks. In the South East many crops […]

Crown rot in winter cereals -Northern region

*Information on crown rot symptoms and management is available in the article Crown rot in winter cereals
Dry seasonal conditions across much of NSW and Qld cropping areas favoured the expression of crown rot in wheat, barley and durum crops in 2017. Unfortunately, dry conditions during winter even resulted in crown […]

Crown rot in winter cereals

Dry seasonal conditions across much of Australia in 2017 favoured the expression of whiteheads in wheat crops associated with infection by the fungal disease crown rot.
Crown rot infection of seedlings is favoured by a wet start to the season. If the season stays wet and/or mild there may be no […]

Eyespot of winter cereals – an emerging disease

Eyespot is a fungal disease of cereals which occurs in medium and high rainfall zones and has been known to occur in paddocks in New South Wales and South Australia for many years. More recently, with changes in farming systems, eyespot has been causing increasing problems in South Australia. In […]

Cucumber Mosaic Virus – sowing healthy seed is critical

Aphid-borne virus epidemics are favoured when a significant source of virus infection is present, and climatic conditions (warm weather, rainfall sufficient for green bridge development) favour aphid buildup. Best management for seed-borne pulse viruses, such as Cucumber Mosaic Virus (CMV) starts with maintaining a healthy seed source. Sowing healthy seed […]

Latest Research from the Science Protecting Plant Health conference

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 […]
