Fusarium graminearum, the primary pathogen of Fusarium head blight (FHB), undergoes both asexual and sexual stages, and the ascospore is an important primary inoculum of FHB. Induction of the sexual stage under laboratory conditions is important for the study of FHB. Here we report a simple culture method that uses potato dextrose agar plates. This method works as well as the traditional procedure, which depends on carrot extracts and involves multiple steps in preparation.
