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 […]
Do you find The Northern Chickpea Ascochyta Diaries useful? Tell us what you think in this 2 minute survey.
These diaries are intended to update chickpea growers in New South Wales and Queensland with the current Ascochyta situation in 2017. They will be updated with observations throughout the season.

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 […]
High grain prices are tempting at the best of times, particularly when another rotation staple is at historical lows. This it the predicament some chickpea growers are facing in the GRDC Northern Region, with high chickpea prices and low cereal prices heading into the 2017 season tempting some growers to […]
With the 2017 growing season approaching, now is the time to set preventative practices in place to minimise the potential impact of disease in this year’s pulse crops. Ascochyta blight was a major issue for chickpea growers across the southern region due to changes in the virulence of the pathogen […]
Following a high incidence of Ascochyta blight in 2016 chickpea crops throughout northern NSW and Queensland, there will be a large amount of ascochyta inoculum to infect 2017 chickpea crops. This inoculum will be present in three forms:
Ascochyta infected chickpea residue being discharged out the back of headers or spread […]

Recommended management for Ascochyta blight and Botrytis Grey Mould (BGM) in the Northern Region has been altered as a result of changes to predicted winter and spring rainfall. It is recommended that growers take a conservative approach to Ascochyta management and use an integrated disease management […]
Sclerotinia on a lupin stem. This will result in total plant death and yield loss.
Reported incidences of Sclerotinia infection in lupin crops have increased across Western Australia’s southern grain growing districts this season. While the focus of the disease is predominantly on canola and lupins, other pulse crops including Chickpea, […]

There are several confirmed reports of Ascochyta blight (AB), caused by the pathogenic fungus Phoma rabiei (previously referred to as Ascochyta rabiei) in commercial crops of the previously resistant chickpeas in the Victorian Mallee.
*It has since been found on the Yorke Peninsula, SA […]
