Three top tips to stop crown rot: rotate crops, observe plants for browning at the base of tillers and test stubble and soil... Reducing the risk before planting Reducing inoculum levels is vital to managing crown rot... Do this by visually assessing crown rot levels in a prior cereal crop or have soil/stubble samples analysed by PreDicta B . If crown rot has been identified as a risk in a paddock, there are a number of ways to minimise the risk for the coming season...

Effect of sowing time and crown rot on yield Sowing time as expected had a significant impact on final grain yield in all three varieties especially EGA Gregory and Strzelecki which are longer season... Effect of sowing time and crown rot on screenings Later sowing significantly reduced grain size in all three varieties with smaller but significant effects from variety and crown rot addition (Figure 3)... Sowing earlier in the window, if soil moisture allows, maximises the genetic yield potential, grain size and limits screenings in a variety...

Key findings Novel trial design allows exact effect of crown rot on yield and grain quality to be separated from environment and site effects... Solid bars are the average yield loss for each variety across the 11 sites in 2007 obtained by directly comparing the yield of plots inoculated with the crown rot fungus with uninoculated plots at each site...

Impact of crown rot on yield and quality is a balancing act between inoculum levels and soil water.. Table 1: Pratylenchus thornei tolerance, crown rot resistance ratings and yield of 10 bread wheat and 1 durum variety evaluated at Gurley in 2012... It is evident that varieties which have good levels of tolerance to Pt combined with some level of resistance to crown rot (even MS) had a significant improvement in yield in the presence of both of these diseases...

In summary, 20 trials have now recently been undertaken across a number of seasons and locations in NSW. None of them have demonstrated S responses in yield or oil %. This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high... Delaying any action that has the potential to cease grain fill will see more seeds achieve their maximum size and improve yield... In summary there was no 'concerning' level of seed loss observed at any trial or timing, correlating well with the yield data...
