Southern region papers Northern region papers Western region papers Read the key messages from each […]

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 […]

Barley disease yield loss response curves

Trial plots for Barley disease yield loss response curves project.Source: Greg Platz.

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 […]

Top 3 diseases to watch for fungicide resistance

Figure 1. A) Barley net form of net blotch, B) barley powdery mildew and C) Wheat powdery mildew have been highlighted in the 2016 Fungicide Resistance Group sampling report.

Three key fungicide resistance findings from the 2016 growing season remind Australian growers to stay vigilant when it comes to monitoring crop disease. These are findings of the annual sampling report by the Fungicide Resistance Group, a program within the Centre for Crop and Disease Management, co-supported by Curtin University […]

How your farm samples help improve varietal resistance

Research programs are often asking for growers and advisors to send in disease samples to assist in their research, but how does this lead to more profitable varieties for you? How are your samples used by researchers to ensure new varieties have improved disease resistance? The following article hopes to […]

New weapon in the arsenal to fight barley powdery mildew

A new genetic discovery from an Ethiopian landrace has potential to significantly improve resistance in barley to powdery mildew. For the first time researchers at the Centre for Crop and Disease Management (CCDM) have found a gene that is resistant to all forms of powdery mildew, without affecting yield. The […]

Webinar: Powdery mildew in wheat and the implications for this season in WA

Early detection of powdery mildew in wheat in the Bindi Bindi region and south of Kadoux prompted the DAFWA team to present a webinar on powdery mildew in wheat and the implications for the 2016 season.  This webinar was presented on July 6, 2016. The key messages from the webinar […]

Using cancer technology for rapid detection of fungicide resistance

Grower samples from last year’s season, along with a machine normally used for detecting mutations in cancer cells, have led to the discovery of the first signs of mutations which could lead to fungicide resistance issues in wheat powdery mildew in Australia. Digital Polymerase Chain Reaction technology picks up mutations […]

Latest on Cereal disease – 2016 GRDC Update papers

Keep up with the latest research information on cereal diseases including Septoria tritici blotch of wheat, spot and net blotch of barley, rhizoctonia root rot, crown rot and the cereal rusts. The following papers were presented at the GRDC Updates across Australia in February and March 2016. Southern region papers […]

Save now, pay later – don’t skip cereal seed treatments

Key messages Seed treatments (pickles) effectively control bunt, smut and powdery mildew. Ensure they are applied every season as a small cost up front will ensure grain is accepted on delivery. Seed treatments are becoming more important for the control of foliar diseases like the net blotches in barley and […]
