Wheat, sorghum, pulses (chickpea, peanut and mungbean), and sunflowers are very important components of the GRDC northern region farming systems, with a combined farmgate value of well over $1 billion pa... The first two crops are the mainstays of these systems, with pulses and sunflowers not only providing niche opportunities but also being break crops with significant soil nutrition and biology impacts... Diseases of the crops have considerable impacts on crop profitability and farm enterprise sustainability...

Pre-sowing assessment of crown rot inoculum levels in paddocks is critical if growers and consultants are to avoid "flying blind" on agronomic management and maximise winter crop production potential... "Following below average summer rainfall for 2013-14 we undertook a Crown Analytical Stubble test for one of our clients near Edgeroi leading into the dry 2014 winter crop season as well as a PreDicta B test to assess Crown rot and nematode levels," Mr Miller said... "Following the results some necessary rotational adjustments to the farm program were made including selecting canola to assist in stubble degradation and the selection of a more crown rot tolerant wheat cultivar, Impala...

HRZ growers urged to be prepared for STB threat.. Mr Poole says rusts are a "puppy" compared to STB because fungicides do not achieve the same level of control as seen with stripe rust in Australia, and because the disease has a longer latent period which makes it more difficult to determine its progress... With the STB pathogen becoming resistant to strobilurins and triazoles in other parts of world and with evidence that the pathogen in southern Australia has some of the early stage resistance mutations to triazoles, Mr Poole is urging growers to use an IDM strategy and not base control on fungicides alone...

"In looking at fungicide options, bear in mind the recent discovery by Dr Andrew Milgate at New South Wales Department of Primary Industries of strains of the disease that show mutations conferring reduced sensitivity (low level resistance) to a number of triazole fungicides," Mr Poole said...

The Grains Research and Development Corporation has developed a new fact sheet to help growers identify, manage and prepare for Barley Yellow Dwarf Virus (BYDV), a disease which can affect all cereal crops... Research scientist Trent Potter says that growers should be proactive and develop a Barley Yellow Dwarf Virus management plan which includes crop monitoring, green bridge management, pre-sowing seed treatment and foliar pesticide sprays... Mr Potter says BYDV is transmitted from plant to plant by aphids, which spread easily throughout regions, specifically when they take flight in autumn, coinciding with critical crop development, and again in spring...
