VELARDE FELIX, Sixto et al. Molecular identification of Fusarium spp. isolated maize in Sinaloa, Mexico. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.8, pp.1675-1689.  Epub Oct 06, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i8.756.

Fusarium species cause macular diseases in the maize that induce rotting of stems, roots and grains of corn and finally the death of the plant. In the present study, the presence and diversity of Fusarium species associated with these damages in Sinaloa was molecularly identified. During the sowing periods in the years 2013-2014, stem and root tissue from young and adult plants, as well as diseased pod kernels, was collected in the municipalities of Ahome, Culiacan and Elota in the state of Sinaloa. In this investigation, species F. verticillioides, F. oxysporum, F. subglutinans, F. equiseti, F. nygamai, F. cf. bullatum and F. andiyazi, were identified by enzymatic sequencing analysis, where F. verticilloides was the most predominant species. Likewise, the presence in Mexico of Fusarium cf. bullatum causing damage to corn.
