A model taking into account physical mechanisms involved in splash dispersal of pathogens and host cultivar quantitative resistance has been developed to study the potential of heterogeneous three-dimensional crop canopies such as cultivar mixtures to prevent disease progression. We investigated different spatial organizations, proportions and resistance levels of wheat cultivars mixtures to allow better control of septoria tritici blotch
