Venn diagram representing the multidisciplinary challenges faced as plant pathology addresses burgeoning issues of food security and environmental stewardship in the twenty-first century. The ring represents the first challenge: the interface between plant pathology, crop protection and other disciplines. Each of the surrounding seven circles represents one of the remaining major challenge areas identified and discussed in the article. All seven of challenges channel results of research into food security and environmental stewardship. The seven challenge areas are themselves interconnected. Sections “Disease surveillance, detection and diagnosis” and “Disease management” have additional, specific areas of challenge discussed herein and indicated by the accompanying smallest circles in this figure
