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 […]

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 […]
Researchers are requesting industry to submit field pea samples infected with bacterial blight from all pea growing regions. This survey will help researchers understand the prevalence of the pathovars within the pathogen population.
Bacterial blight disease in field pea is caused by the bacterial pathogen, Pseudomonas syringae. There are two pathovars, pv.syringae […]
