Blackspot Manager is a forecasting model for ascochyta blight (synonym: blackspot) of field peas. It can be used by agronomists and growers to help identify the best balance between early sowing and potential yield loss from ascochyta blight. Windborne ascochyta spores are released from infected stubble early in autumn, with timing […]

The Cereal Disease Guides are essential reading to learn about the latest changes to disease resistance. The Guides also summarise what happened in the last season and what diseases are likely in the coming year.
The resistance ratings in the guides are an important management tool because they provide a guide […]

This guide is provided to help growers and agronomists identify common faba bean diseases in the field including ascochyta blight, cercospora leaf spot, chocolate spot, alternaria leaf spot and rust. Correct identification is important because different fungicides are used to manage different fungal diseases.
In particular ascochyta blight, chocolate spot and […]
*Information on crown rot symptoms and management is available in the article Crown rot in winter cereals
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 […]
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 […]
We interviewed Marg Evans from SARDI about Eyespot, a fungal disease of cereals which occurs in medium and high rainfall zones. The disease has been known to occur in paddocks in New South Wales and South Australia for many years. In this short video Marg discusses symptoms, management and current […]
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 […]

Figure 1. Blackleg leaf lesion on canola
Blackleg is a fungal disease of canola that can cause severe yield loss. It is more severe in areas of intensive canola production as fungal spores are released from the previous year’s canola stubble and spread by wind and rain splash. With good management yield loss […]
