Bacterial blight survey to inform breeding efforts

Symptoms of bacterial blight on Kaspa field peas grown at Horsham, Victoria

Following on from samples submitted in 2017, researchers are again this year requesting industry to submit green field pea samples infected with bacterial blight from all pea growing regions. These samples will help researchers understand the prevalence of the pathovars within the bacterial blight pathogen population. Bacterial blight disease in […]

Blackspot Manager for field peas

Blackspot field peas

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 […]

Mungbean powdery mildew management with fungicide

Powdery mildew of mungbean, white fungal growth, on upper leaves of maturing mungbean plant

Caused by the fungus Podosphaera xanthii, powdery mildew of mungbean  is responsible for yield losses of up to 40% in  susceptible varieties within Australia. Plants are susceptible to the disease from the seedling stage onwards, with the first sign of infection being small, white circular patches on the lower leaves […]

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 […]
