Growers are now able to utilise the PREDICTA® B DNA-based soil test to detect the presence of Ascochyta blight inoculum (Phoma rabiei) in their paddocks. Initial testing has shown that the Ascochyta fungus was detected in 35 per cent of samples from the Northern Region. This finding is a concern […]

Chocolate spot has been found in some early sown vetch crops in the Northern Victorian Mallee. This disease develops in warm and humid canopies. Given suitable conditions this can be a damaging disease that may warrant control with fungicides, […]
During 2017 there is an increased incidence of canola white leaf spot in many regions of southern Australia. The disease is distributed worldwide, but in Australia, it is not usually severe enough to cause yield loss. However, if environmental conditions are favourable, it can result in significant defoliation causing reduced […]
During 2015 and 2016 the blackleg fungus overcame the blackleg resistance of some Group A cultivars. These cultivars dropped from Moderately Resistant (MR) to Moderately Susceptible (MS) and all updated ratings are available in the 2017 Autumn Blackleg Management guide. In the lead up to the 2017 season, fungicide application […]
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 […]
Leading into the 2017 season the risks presented by Ascochyta blight in chickpeas are at an elevated level. The occurrence of a new virulent strain of the Ascochyta blight pathogen has resulted in all resistance ratings being revised to susceptible or moderately susceptible. Throughout the Southern Region there is also […]

Monitor crops for blackleg
Growers are usually encouraged to monitor for blackleg in the spring. However, in 2016 widespread, severe early blackleg leaf lesions have occurred across Australia’s canola growing regions.
The increased incidence of early disease is due to the following key factors:
continued leaf wetness driving the disease cycle;
the blackleg […]
Stubble-borne diseases such as yellow leaf spot (YLS) of wheat and spot form of net blotch (SFNB) of barley will need to be monitored during 2016 and foliar fungicides applied where necessary. These diseases will be common and most severe in early sown crops with wet seasonal conditions across the […]
