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...

Yield losses in crops affected by bare patches can be over 50% and crops with uneven growth (Figure 1) may lose up to 20%... Figure 1: Above-ground symptoms of crop unevenness (main picture) are seen when Rhizoctonia damages crown roots, even when seminal roots (inset) escape the infection... Inoculum levels increase in cereal crops at all depths...

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."..
