Resumen

HERNANDEZ JUAREZ, Agustín et al. Incidence and severity of ear rot on genetically modified and conventional maize in Sinaloa, Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.6, pp.1477-1484. ISSN 2007-0934.

It was assessed in genetically modified (GM) maize with Agrisure® VipteraTM 3111, the incidence and severity of ear rot by Fusarium sp., in two locations from Culiacan, Sinaloa. In El Camalote, the hybrid showed incidence and severity of 47.2 and 22.5% respectively; compared to conventional hybrid with pest control showed 54.7 and 27.1% of incidence and severity of rot and conventional hybrid (control), had further damage with an incidence of 59.4 and severity of 35.2%. In assessing Oso Viejo, the hybrid Agrisure® VipteraTM 3111 showed less damage with 25.7 and 7.6% incidence and severity of the disease respectively; the conventional hybrid with pest control had an incidence of 67.5% and severity of 38.7%, and control had the highest damage 80.8 and 53.5% of incidence and severity. Agrisure® VipteraTM 3111 corn was not developed for disease management, however; the findings show that the genetically modified maize confers an indirect additional benefit to pest resistance, preventing the formation of entry points for pathogens that develop in susceptible tissue, causing ear rot.
