RIOS HERRERA, Erika Natalia et al. Fungi associated with the tar spot in maize cultivation in Mexico. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.2, pp.457-462. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v8i2.65.

The objective of this study was to identify phytopathogenic fungi associated to the tar spot in corn in two states of the Mexican Republic, Chiapas and Guerrero. The conducted samples of leaves with symptoms of the disease were performed. The preliminary identification of the pathogens associated with the symptoms was performed using morphological criteria with dichotomous keys and was corroborated by the amplification of the internal transcription spaces (ITS) sequenced and analyzed in the NCBI database. In both states he found Phyllachora maydis, Curvularia lunata and as first report of the association of this syndrome called tar spot.
