Potential threat to global wheat production
Wheat blast, caused by the Magnaporthe (Pyricularia) oryzae Triticum pathotype (MoT) is an emerging disease considered a limiting factor to wheat production in various countries in South America. Given the importance of wheat around the World, blast is regarded as a potential major threat. Strains of M. oryzae that can cause significant disease effects on wheat could become established in new regions based on independent scenarios (e.g. isolates of MoT may be introduced from South America via man-mediated transport of MoT-contaminated plant materials). Therefore, it is paramount to prepare for incursion and prevent establishment of the South American MoT fungus in various wheat regions of the World.
