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 […]
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 […]
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, […]
Charcoal rot was confirmed in a number Western Australian lupin crops in 2014 (DAFWA Pest Fax newsletter, No. 20); a likely consequence of the hot and dry conditions experienced during August.
Normally charcoal rot does not reduce lupin crop yields as symptoms only appear after pod set. However, unseasonable heat in […]
Chickpea and other pulse crops in the Northern region can be significantly affected by a range of aphid transmitted viruses as was observed in chickpea crops in 2012 and 2013.
The effect of virus infection on plants include stunting, reddening, chlorosis, distortion, shoot tip wilting, reduced yield and grain quality and […]
