Yield loss data is often generated by comparing trial plots with high disease levels and plots with no disease. Yield loss figures are then calculated based upon potential yield loss as a percentage of maximum yield in a susceptible variety. In an on-farm situation, disease pressure is more likely to […]
Topic: net blotch
After a bumper season in 2017 Victorian growers are reminded to be proactive in monitoring and management of barley diseases. Mark McLean, Barley Pathologist with Agriculture Victoria spoke to us at the Bendigo GRDC Updates and gives growers a heads up of what diseases are likely to pop up in […]
Stubble-borne diseases such as yellow leaf spot (YLS) of wheat and spot form of net blotch (SFNB) of barley will need to be monitored during 2016 and foliar fungicides applied where necessary. These diseases will be common and most severe in early sown crops with wet seasonal conditions across the […]

Cold weather can cause a physiological response in crops leading cereal leaves to turn yellow and barley to develop brown spots. These can be easily confused with disease symptoms and there can be a temptation to respond with a fungicide. It is […]
By Mark McLean, DEDJTR Victoria.
Spot form of net blotch (SFNB) can reduce grain yield and quality if it becomes severe. Check crops early in the growing season and be prepared to apply a foliar fungicide if necessary.
Application of foliar fungicide is an important management tool that can provide effective suppression […]

Nick Poole, Foundation for Arable Research (FAR) Australia talks about fungicide resistance at the GRDC updates in Adelaide, February 2015.
He warns not to rely on fungicides to control Net Form of Net Blotch (NFNB) and Septoria tritici Blotch (STB). Use an Integrated Disease Management (IDM) package to prevent pathogen resistance […]
