Conditions in Western Australia during the 2018 growing season were favourable for the development of sclerotinia in canola crops. Sclerotinia apothecia were first observed mid-July in Geraldton and persisted until September in many places. Infection in canola was detected as early as August with the first report being received in […]
As the 2018/19 summer cropping season draws to a close, sorghum growers are once again confronted with an unfortunate all too familiar problem with charcoal rot and lodging in their paddocks (Figures 1, 2 and 3). This summer season was a text-book case where conditions were ideal for the disease […]
Net form of net blotch is a damaging foliar disease of barley in susceptible varieties. Grain yield and quality losses occur where yield potential is greater than 3 t/ha. At least two, well timed fungicide applications are required to minimise losses. Background Net form of net blotch (NFNB) is a major […]
A range of smart phone and tablet apps and online tools, developed in conjunction with Australian plant pathologists and grains researchers, are helping farmers to identify crop diseases and construct appropriate management plans with just the push of a button. With smart phone and tablet adoption by farmers now exceeding that […]
Disease surveillance on winter grain crops in the GRDC Northern Region showed no major disease issues from July to September 2018. Joining with Dr. Kevin Moore, a chickpea pathologist from NSW-DPI (Figure 1), more than 60 chickpea crop paddocks across central Queensland, southern Queensland and northern NSW were visited. Very […]
Applying fungicides to cereal seed, or in-furrow at sowing, are common management practices for managing various seed borne and foliar fungal diseases – particularly smuts, net blotches, and powdery mildew. As with any input, it is important to choose the right product and rate to get optimum efficacy. It is also […]
Take a look at the most popular top five articles articles and videos from 2018. In 2018 GRDC Communities Field Crop Diseases published 27 articles covering many disease issues which impact on grains production. These articles were prepared with, and reviewed by, members of our Community of Practice, Australia’s leading […]
Fran Lopez-Ruiz from the Centre for Crop and Disease Management (CCDM) explains the recent detections of fungicide resistance to spot form of net blotch in barley and the importance of its management, especially in southern Western Australia. The CCDM has received and analysed multiple samples from barley paddocks which have […]
Main points Barley loose smut infections are becoming more common in varieties such as Spartacus CL, LaTrobe, Rosalind and Hindmarsh. Growers need to ensure that seed of these varieties have good coverage of an effective seed treatment fungicide prior to sowing in 2019. Situation Loose smut continues to be observed […]
The Blackleg Management Guide not only provides blackleg resistance ratings but also blackleg resistance groups for current canola cultivars. But how do researchers determine these? Steve Marcroft talked us through how researchers establish resistance groups for canola cultivars, and more importantly, why you should know the resistance groups of the […]
