At a trial site near Yallaroi in 2012, a range of crops and varieties were grown where performance was evaluated in strips with contrasting starting levels of Pt ... All varieties evaluated in all 9 trials except CICA0912 (only 6 trials).. Differences in Pt populations following a range of crops assessed at two sampling times during the fallow, Yallaroi 2012..

Over the three survey years this allowed 307 comparisons of Fusarium DNA levels assessed at sowing using PreDicta B with the actual incidence of infection that developed by harvest as determined from laboratory plating (Table 1)... The predicted risk of crown rot development at sowing using PreDicta B was within one category of the actual level of infection measured after harvest in 121 paddocks (39%, light grey shading)... In other regions a shallower sampling depth (0-10 cm or 0-15 cm) is recommended with PreDicta B. In 2013 we aimed to determine if this deeper sampling depth in the northern region, to account for RLN populations deeper in the soil profile, is potentially compromising the accuracy of PreDicta B to measure levels of other soil-borne pathogens including Fusarium ...
