The impact of climate change on specific biotic constrainers like pathogens and on the host-pathogen relationship is associated with changes in pathogens life cycles, increased incidence, pathogenicity, genetically recombination and aggressiveness traits, which require rethinking the integrated management strategies. However, the results of investigations are inconsistent and poorly understood in the context of climatic change. The present review is focused on the influence of crop management on Septoria Tritici Blotch (STB) disease in winter wheat in the context of climate change taking into consideration case studies in order to understand better how the components of disease cycle are affected and to identify disease risk of different agricultural practices. The response of Zymoseptoria tritici pathogen to climate change is of high interest currently in order to estimate disease risk on a large scale and to introduce new understandings in developing management strategies. Soil tillage, crop rotation, sowing date and nitrogen fertilization are considered important tools in disease control which need to be adjusted according with climatically factors for each area which affect the dispersal of ascospores and pycnidiospores of the pathogen. However, further investigation need to be done in order to highlight the impact of climate change on foliar wheat pathogens and which are the most appropriate management tools in order to control these pathogens and to enhance global food security in a changing climate.
