La fusariose des épis des céréales à paille : synthèse de 10 années de recherche pour une meilleure gestion intégrée de la maladie.

Abstract : Fusarium head blight (FHB) is a cereal disease caused by a complex of plant pathogenic fungal species of the genera Fusarium and Microdochium, with different epidemiological characteristics and producing or not different toxins. The FHB causes significant yield losses, health issues and technological quality concerns in all temperate areas worldwide. The composition of the species complex is different according to the cereal, depending on the climate of the year and the agronomic practices. These species may have different susceptibilities to the fungicides used and different behaviors towards genetic resistance. Thus, investigating these characteristics is required to implement integrated pest management strategies adapted to this disease. For more than 10 years, several research programs have led to significant progress in this area. Tools have been developed to more accurately characterize fungal populations and their interactions. Models have been developed to predict the risk and to adapt control measures. The molecular mechanisms involved in the interaction between plant genes and the pathogenicity of fungal species are beginning to be deciphered. Phenotyping methods are being developed to help in the characterization of varietal susceptibility and direct control methods using biocontrol products are under investigation. The goal of this paper is to review the main results obtained in the context of integrated management of fusarium head blight.
