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 […]

Training Growers Podcasts

Training growers podcast

This series of podcasts is hosted by Dominie Wright, Research Officer with DPIRD, WA. Dominie discusses current pest and disease issues relevant to WA growers and advisers with DPIRD researchers. The episodes cover: Russian Wheat Aphid in Crops with Dusty Severston Slugs in Crops with Svetlana Micic Earwigs in crops […]

Keep an eye on barley loose smut infection levels prior to harvest

Low levels of loose smut are being observed in some barley crops in Victoria, South Australia and southern New South Wales, particularly Hindmarsh, LaTrobe and Spartacus. Loose smut has been an issue in Hindmarsh in SA and WA in previous years. Smut infections have been found in crops that have […]

Bacterial blight in field peas

Exacerbated by frost events, severe bacterial blight has recently been reported in the Mid and Upper North and Upper Eyre Peninsula of South Australia, increasing the importance of containment measures. Multiple frosts can cause bacterial blight epidemics to develop and may result in significant yield loss as the conditions provide […]

Chocolate Spot in faba beans

Chocolate spot is one of the most severe disease of faba bean in Victoria, SA and NSW, and occurs in all areas where the crop is grown.  In light of recent persistent rains across the southern region, frequent rainfall events in combination with wet soils will contribute to humidity beneath […]

Botrytis Grey Mould of Lentil

With Botrytis Grey Mould (BGM) recently found in early sown lentil crops sown on narrow rows, vigilant disease monitoring and management is crucial now to minimise impact and yield loss. Conducive growing conditions this season have resulted in heavy crop canopies in many districts of South Australia and Victoria, which […]

Russian wheat aphid numbers increasing with spring upon us

Growers and advisors will need to remain vigilant and monitor crops closely for the presence of Russian wheat aphid (RWA), particularly in the Wimmera/Mallee region. Current reports indicate that RWA is widespread in the Wimmera and populations are becoming more evident in the Mallee. Russian wheat aphid has also been […]

Apply fungicides to rusts emerging in Victorian cereal crops

Wheat leaf rust, barley leaf rust and wheat stripe rust have all been found in Victorian cereal crops. Growers and advisors are advised to inspect cereal crops for symptoms (Figure 1) and determine the need to apply foliar fungicides. Check the latest disease resistance ratings in the Victorian Cereal Disease Guide to identify varieties […]

Apply fungicide to control Ascochyta in previously resistant chickpea crops

Chickpea growers in South Australia are advised to apply preventative fungicide sprays in chickpea crops ahead of rain events for Ascochyta blight control and continue to monitor the disease after reports of disease on previously resistant varieties. Following on from reports of severe Ascochyta blight affecting previously resistant chickpea varieties […]

Continuous wet provides ideal conditions for Sclerotinia collar rot in lupins

Lupin crops across Victoria’s lupin growing regions have been experiencing high levels of Sclerotinia collar rot (caused by Sclerotinia minor) causing main stem infections as a result of cool wet conditions conducive to the disease. Some crops have been badly affected, particularly in the Victorian Mallee where infection levels of […]
