Mycosphaerella graminicola

(Septoria tritici blotch - STB) is the main foliar fungal disease of wheat, present in most wheat-growing areas worldwide. The disease is clonally propagated among wheat plants during the growing season by pycnidiospores, which are splash-dispersed upwards over short distances. The progress rate of the epidemic and then the final disease severity are determined by the number of asexual, embedded infection cycles completed by the pathogen, depending mostly on temperature and rain events. Primary inoculum and the early stages of STB epidemics are still not fully understood and deserve attention for improving management strategies

Management approach

For biological control agents: Metagenomic microbiological & epidemiological approaches for identifying microbes as potential bio-controls

Cultural controls: Rotation and crop management

Solution proposed by EMPHASIS

For biological control agents: Screening of microbial BCAs candidate for L. maculans and M. graminicola control on debris (PU)

Cultural controls: Guidelines for crop debris management and enhancing the action of some microbes as direct or indirect biological control in a wheat/oilseed rape rotation (PU) and Protocol for debris management
