Be in the know before you sow
29 April 2019
Victorian field pea growers are being urged to use the Blackspot Manager alert service to predict their field pea disease risk this year.
Blackspot Manager is a model for each field pea growing district in Victoria. It is based on spore release and rainfall and is updated fortnightly to provide the risk level of field peas being infected by blackspot.
The model uses rainfall to predict when spores are released in each district. With a dry summer, less spores are released and therefore, when initial rains occur, there are high numbers of spores released that can then infect plants. After more rainfall events, less spores are released and there is a decrease in disease risk. This allows growers to identify the best balance between fungicide management, sowing time and potential yield loss.
Growers can then change their management plan based on the predicted risk. This means growers can adjust their fungicide plan to the risk level in their district or delay sowing to reduce fungicide inputs.
Following a dry summer, less spores have been released and the risk of blackspot in field peas is high, but growers can use the Blackspot Manager to predict their risk before sowing.
Agriculture Victoria research scientist, Dr Joshua Fanning, said a proactive disease management strategy is key to increasing yield and the Blackspot Manager is one tool that can help.
Dr Fanning is encouraging Victorian field pea farmers to sign up to the SMS text messaging service to help reduce losses from this disease.
Information on the Blackspot Manager website is updated every two weeks from April through to June according to rainfall information.
“To sign up for the SMS alert service, text BLACKSPOT, your name and your nearest weather station or your location to 0475 959 932,” Dr Fanning said.
The service is also available via email, simply email your name and your nearest weather station or location to BlackspotManager@agric.wa.gov.au
Blackspot Manager, which was developed by the Grains Research and Development Corporation and the Western Australian Department of Primary Industries and Regional Development, is updated in collaboration with Agriculture Victoria based on local conditions.
