- Abstract
- Fusarium head blight (FHB) is a common fungal disease in winter wheat in Belgium causing yield losses and sanitary problems due to the production of mycotoxins by species associated to the disease. Fusarium graminearum (teleomorph Gibberalle zeae) is one of the important species involved in the species complex causing FHB and is able to produce wind dispersed ascospores by sexual reproduction. In order to analyse the distribution of airborne inoculum of G. zeae along the year and specially between heading and flowering and to understand the role of this inoculum in the infection of the ears, a network of Burkard spore traps was set up in fields in Walloon Region in Belgium during the cultural season 2011-2012. Total DNA from each fragment of spore trap tape corresponding to 1 day sampling was extracted and the quantity of G. zeae was assessed using a real-time polymerase chain reaction (PCR) assay. First results showed the occurrence of G. zeae airborne inoculum between heading and flowering. The relationship between the distribution of airborne inoculum and the prevalence of G. zeae on infected ears collected in fields was studied in order to evaluate if spore traps coupled with real-time PCR can be used to improve the understanding of the epidemiology of FHB, the prediction of this disease and the control strategies.
