Growers in high rainfall zones should be proactive and develop a Barley Yellow Dwarf Virus (BYDV) management plan which includes crop monitoring, green bridge management, foliar pesticide sprays and pre-sowing seed treatment... Trial results have found that the oat and rose grain aphid are found on wheat and barley and the corn aphid favours barley and is rarely found on wheat... Even where there have been large yield losses due to BYDV, trial results have not shown any difference in protein content between sprayed and untreated plots...

"Of the 27 crop pathogens studied so far using growth cabinets with temperature and CO 2 controls, disease severity was found to increase for a majority of pathogens under high temperatures and CO 2 ," Dr Chakraborty says... We can expect new pathogen strains to emerge after fewer infection cycles.".. Dr Chakraborty states that our current knowledge is inadequate to deal with plant disease impacts and that the kind of experiment he favours is called 'FACE' - free to air CO 2 enrichment - in which communities of plants and pathogens are studied under field conditions but with artificially raised levels of CO2...

Northern region Grains Research Updates coordinator John Cameron reflects on the vast changes that researchers and growers have implemented over the past two decades, and the one problem that just will not go away - weeds.. No-till has become crucial to northern grains production but faces a major weed-control challenge... In the short term, the no-till system will be defended by tactics such as pre-emergent herbicides, double knock using paraquat, and the use of tillage when weeds cannot be or are uneconomical to control using herbicides...

Frost is one of the main concerns for growers in Western Australia's southern grain growing areas, along with crop disease and the need for better break crops... Growers are also seeking more detailed information about crop varieties, and those in drier areas want research into issues associated with early crop sowing, particularly dry sowing... "Growers' desire to sow crops early to maximise yield potential is compromised by the reality of frost risk," he said "While growers understand that frost is a difficult research issue, they want the GRDC to maintain a major focus in this area and look for even small areas of improvement...

In the central to west Midlands region where I work as an agricultural consultant, I didn't see much evidence of disease until about mid-June... But as temperatures have dropped, crops have slowed in growth and many have turned a bit yellow... Growers are encouraged to take part in the campaign and submit samples so researchers can recover current strains of the fungus, monitor the pathogen and stay on top of any changes, so they are best placed to combat it...

'Bio-security, Food Safety and Plant Pathology: The Role of Plant Pathology in a Globalized Economy' was the theme of the 10th International Congress of Plant Pathology (ICPP) hosted by the Chinese Society of Plant Pathology... ' the new technique works by trapping the spores of the pathogen and automatically germinating these in growth medium within the trap.'.. Populations collected from distant regions in Brazil demonstrated that this pathogen has potential for long-distance dispersal, highlighting the need for Australia to maintain strict biosecurity controls when exchanging material between continents...

Western Australian growers can obtain information and direct specialist feedback about fusarium crown rot and other topical agronomic issues by visiting the recently launched web platform eXtensionAUS... By visiting www.extensionaus.com.au/crown-rot-cereals-western , growers can access regionally-specific information to help them manage the disease and post questions that will be answered by experts... The national eXtensionAUS web platform can also be used by growers to obtain information and request answers to other issues relating to crop diseases and nutrition...

Farmers have responded by growing more cereals... The action is risky, where herbicide resistant weeds can quickly become a problem and the populations of soil borne diseases such as take all and crown rot may increase in ideal conditions and devastate a cereal crop... The project will deliver an economic framework to help determine appropriate 'rules of thumb' for growers about what crop to grow given current costs and prices, yield expectations for the season, the previous crops grown, weed populations and the presence of disease...
