wheat disease

Catalogue: GRDC Research Summaries
Foliar diseases are a major constraint to national wheat yield stability, and cause annual industry wide costs ranging from yield loss and down grading of grain, to chemical control expenses and removal of preferred varieties from recommendation lists... The importance of wheat diseases to Australian cereal producers was highlighted in a GRDC commissioned study that was published in September 2009... The study by Murray and Brennan (2009) on the economic impact of wheat diseases estimated that stripe rust caused current.....

Overall, barley diseases have the potential to cause very significant costs for farmers... Incidence is 30 per_cent frequency in 30 per_cent of the area, so that the average incidence of the disease affecting the crop is 9 per_cent... Overall, breeding contributes more than 25 per cent of the control for 14 diseases, cultural methods for 32 diseases, and pesticides for six barley diseases...

The cause of septoria nodorum blotch on wheat, Parastagonospora nodorum , can reduce wheat yields by 10 to 20 per cent despite the application of fungicides and a heavy focus on plant breeding over the past 30 years... Despite missing the ability to make and secrete the encoded proteins, the mutant fungal strain still retained the ability to infect wheat... "Already by providing the option of effectors and markers to breeders, we have helped breed wheat with much better disease-resistant profiles, which has saved the industry millions of dollars through improved yields."..

SARDI's Dr Margaret Evans says yield loss from eyespot comes as a result of the lesions forming on the base of the stem and lodging... Growers in high and medium rainfall zones across the Southern Region are being asked to keep a look out for eyespot in cereal crops this season after the disease made a surprise appearance in a number of wheat crops in 2015... Yield losses from eyespot are most obvious when caused by lodging, which is when plants infected by the fungus fall over in different directions and form a tangled mess on the ground, making harvesting difficult...

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...

Wheat infected with crown rot.. Prof. Sutherland said the first step in finding a solution was identifying lines of wheat with significantly better resistance these were five low-yielding, unadapted wheat germplasm that did not grow well in Australian conditions... "The aim then was to get this resistance into lines of wheat adapted to Australia possessing other traits that farmers require," Prof. Sutherland said...
