Triazole fungicides have not been effective for managing the wheat blast disease in Brazil. A broad analysis across six geographicalpopulations of Pyricularia graminis-triticiin central-southern Brazil indicated a high level of resistance to triazole fungicides. Since P.graminis-triticiis also associated with others poaceous species,here, we analyzed whether triazole-resistant isolates of the blast pathogencould be recovered from other poaceous hosts that are invasive of sprayed wheat fields. In addition to P.graminis-tritici (Pygt),we also evaluated the levels of sensitivity of three other grass-associated blast pathogens, which included P. grisea (Pg), P. pennisetigena (Pp), andP. urashimae(Pu).Resistance to the triazole fungicides tebuconazole and epoxiconazole was assessed phenotypically based on EC50 values and molecularly by analysis of the presence of mutations in the CYP51Agene, which encodes for the target enzyme 14-alpha-demethylase. We detected triazole-resistant Pyriculariaspp. (Pg, Pp, Puand Pygt) that is associated with Avenasativa, Cenchrusechinatus, Chlorisdistichophylla, Cynodonsp., Digitaria horizontalis, D. sanguinalis, Panicummaximum or Urochloaspp. The major outcome from our study was the evidence that invasive poaceous species from wheat fields could be an important source of triazole resistant fungal inoculum for the initial phases of the wheat blast epidemics.Keywords:blast disease; CYP51A gene; sterol demethylation inhibitor (DMI) fungicides; epoxiconazole; tebuconazole.
