High-throughput screening of new biofungicides and plant defence inducers on wheat against Zymoseptoria tritici

In a global context of pesticide use diminution all over the European Union, new means of alternative crop protection have to be developed. One of them is biocontrol wich is defined as a crop protection method package using living organisms or natural substances 1 . • Under these circumstances, the European project portfolio Smartbiocontrol was established to promote the use and development of biocontrol products in the Belgium-France cross-border area2 . • One of the targeted disease is Septoria tritici blotch (STB), one of the European Union’s most devastating foliar disease on wheat. • A total of more than 200 biomolecules or extracts of diverse origins have been tested for in vitro antifungal activity and elicitation effect. The objective of this project is to identify new biocontrol products and characterize their modes of action on the wheat-Zymospetoria tritici pathosystem
