Cereal disease authorities, supported by the Grains Research and Development Corporation (GRDC), say fungicides have an important role to play in disease control but they should be seen as just one component of an overall management strategy... "And while fungicides can be very effective in offering protection from diseases, they must be used judiciously and as part of a multi-faceted management strategy which should also include c ontrolling the green bridge for cereal rusts, attention to the potential risk of stubble-borne leaf disease when deciding on crop rotations, and avoiding susceptible varieties... The Fact Sheet provides information on identifying and understanding fungal diseases, cereal disease diagnosis, fungicide modes of action, foliar fungicide timing, tips for optimal fungicide efficacy, the economics of using fungicides, fungicide resistance, and stewardship...

A new Grains Research and Development Corporation (GRDC) fact sheet brings together the latest results and recommendations from nine current cereal disease research projects for northern region growers... Cereal fungicides - Northern Region outlines how and why growers should assess disease risk, including pre-planting tactics such as determining the risks posed by retained stubbles and over-summering weeds and cereal volunteers... Region North < Keep browsing 0 Responses to Swatting up on cereal diseases..

YELLOW LEAF SPOT RESOURCE: Southern region grain growers are being provided with a useful resource as they endeavour to reduce the incidence of yellow leaf spot... The Grains Research and Development Corporation (GRDC) has developed a new fact sheet, Management to reduce the risk of yellow leaf spot, to support growers in their efforts to combat the disease... Yellow leaf spot does not affect oats or green barley plants, although barley stubbles can host the pathogen and generate inoculum for the following season...

Northern New South Wales grower and agronomist Drew Penberthy is road-testing new research findings on a DNA-based soil test to help better predict crown rot risk in northern farming systems... "New soil sampling techniques for the PreDicta B test could provide savings in terms of the preparation and analysis of stubble testing for crown rot," Drew says... Drew, who also runs a business that provides stubble testing for crown rot and soil testing for root lesion nematodes, says most growers in the northern grains region undertake two separate tests for these cereal pathogens...

Crop disease management in water limited environments A feature of cropping enterprises in the water limited environments of the northern and central agricultural regions of WA is the intensive cereal rotations used to maintain profitability and manage weeds... The project will develop disease management recommendations for intensive cereal rotations to enable growers to minimise the impact of foliar and root diseases on cereal yields... Maintaining market access Changes to the World Trade Organisation legislation now require that countries participating in international trade, such as Australia, must prove that specific grain pests and diseases exotic to importing countries are known not to occur in the exporting country...

The overall objective of this research program is to develop and deliver strategies for management of plant diseases of importance to SA grains industries... The increased frequency of cereals and greater adoption of susceptible cultivars is creating an opportunity for cereal cyst nematode (CCN) to re-emerge as a significant problem in the southern region... Subproject 3 continues existing monitoring and surveillance of new races and pathogen threats; this subproject will link with newly appointed grains biosecurity officer in SA. Subproject 4 focusses on rebuilding a joint capability in the southern region to address key issues in cereal nematology, most critically preventing CCN re-emerging as a significant problem...

In many cropping soils of south-eastern Australia the presence of nematodes limits field crop production... Recent reports by Murray and Brennan (2009 a & b) estimated that in south-eastern Australia alone, nematodes are currently reducing wheat and barley production by 4.9% ($98 million) and 5.1% ($42 million) respectively, with losses in excess of 20% possible in the absence of appropriate control strategies... Growers can minimise yield loss caused by the nematodes in two ways...

Foliar diseases cause significant yield losses to grain crops across Australia, leading to millions of dollars in lost GDP. Crop yield and grower revenue/profit could be increased through up-skilling the county's farm advisers who work with growers to maximise grain production and profitability... The range of crop diseases, growing environments, and new strains of foliar diseases, require a diverse range of management tools for cost effective management... The Grains Research and Development Corporation will support a two-day workshop at Temora, NSW, in March, which will deal with the cutting edge of cereal disease management, enabling advisers to pass on the latest knowledge and insights to their grain-growing clients...
