Abstract
During the past 20 to 30 years, Fusarium crown rot (FCR, caused by Fusarium pseudograminearum and/or F. culmorum) has become one of the most important diseases of wheat crops in Australia. As a stubble borne disease of cereals and grasses its prevalence has increased with the widespread adoption of stubble retention cropping practices and intensification of cereals in the cropping system. A recent study of the economic impact of FCR in Australia, based on inoculum levels in 5,993 fields (2015 to 2017) determined using qPCR molecular analysis (PREDICTA®B), estimated average annual losses of 6% (A$404 million) with losses of 8-10% possible across the regions. These losses were estimated using the negative relationship between pre-sowing inoculum density in the field and grain yield in seasons with hot and/or dry conditions during grain filling; with yield loss often not measured in seasons with a wetter and cooler seasonal finish. Australian growers can use PREDICTA®B testing commercially to identify fields at risk of FCR infection to plan rotations to minimise loss from this disease.
