Grain growers across New South Wales and Queensland are being reminded to follow updated sampling techniques when assessing the risk of disease threats including crown rot and root lesion nematodes... Crown rot is caused by the fungus Fusarium pseudograminearum and is one of the most serious disease threats to winter cereal crops in Australia... DNA-based soil test PreDicta B is recognised as a reliable technique for identifying the level of risk for crown rot, and other soil-borne pathogens within paddocks prior to sowing...

An authority in soil science is among those suggesting closer long-term scrutiny of soil health using precision agriculture (PA) technology and on-farm trials to rectify areas where crops under-perform because of poor water use efficiency... Esperance-based David Hall, of the Department of Agriculture and Food, Western Australia (DAFWA), says root growth and water use by crops are often restricted by subsoil constraints including sodicity, salinity, boron toxicity and acidity which, to some extent, can be alleviated by applying gypsum... At the Mt Madden Field Walk in September 2010, Mr Hall observed the crop growth differences between the treatments highlighted the short-term benefit of gypsum in helping to increase crop emergence, root growth, water infiltration and water storage...

Application of nitrogen to most crops will affect grain yield, grain protein or both, depending on the available nitrogen supply relative to crop demand... Soil analysis conducted recently have indicated that EC, sodicity and chloride content have increase in the root zone of some soils due to capillary rise arising from the extended dry period... Environment mean yield (t/ha) d) Reduced tillering Several years ago I proposed that the incidence of haying-off could be reduced by increasing the storage of stem sugars by several means...

Current research is helping boost the accuracy of the PreDicta B test in assessing crown rot risk by fine tuning soil sampling techniques and recommendations... PreDicta B is a good technique for identifying the level of risk for crown rot and other soil-borne pathogens prior to sowing within paddocks but requires a dedicated sampling strategy and is not a simple add on to a soil nutrition test... There is no detection issue with the current PreDicta B tests that were resulting in an underestimation of crown rot risk...

A replicated field trial examining crown rot tolerance in different wheat and barley varieties at Tamworth, NSW. Note the white heads caused by crown rot in plots across this 2014 trial... Trials at the NSW Department of Primary Industries (DPI) in 2013 and 2014 showed that some new bread wheat varieties produce higher yields in the presence of crown rot infection than the more popular wheat variety EGA Gregory ... "Crop and variety choice is not the sole solution to crown rot, but rather just one element of an integrated management strategy to limit losses from this disease."..
