Management of Wheat Blast Disease in Bangladesh Caused by <i>Magnaporthe oryzae</i> Pathotype <i>Triticum</i>

Wheat blast, caused by Magnaporthe oryzae pathotype Triticum (MoT), poses a critical threat to wheat production in Bangladesh and global food security. Since its first outbreak in Bangladesh in 2016, the disease is likely to spread across major wheat-growing regions in the world, with potential yield losses reaching up to 100% under conducive conditions. Existing control measures, including resistant cultivars, fungicides, and agronomic practices, have shown limited and inconsistent efficacy due to the pathogen’s high genetic variability and strong interaction with environmental factors. This case study outlines a comprehensive, field-oriented approach to wheat blast management, emphasizing the integration of real-time surveillance, host resistance, biocontrol agents, molecular diagnostics, and climate-resilient agronomic practices. Innovative technologies such as field pathogenomics and CRISPR-Cas mediated crop improvement, particularly adapted for low-resource settings, are highlighted as critical components of a long-term solution. This case study also focuses on the urgency of coordinated international collaboration and farmer-centric outreach to implement sustainable, adaptable strategies for managing wheat blast in Bangladesh and other high-risk regions before it becomes catastrophic.
