MARQUEZ-DIEGO, José Jesús et al. Incidence of monkey´s hand in maize germplasm from different locations in Mexico. Rev. mex. fitopatol [online]. 2022, vol.40, n.3, pp.425-432.  Epub 14-Nov-2022. ISSN 2007-8080.  https://doi.org/10.18781/r.mex.fit.2204-1.

The incidence of maize monkey´s hand disease was determined in nine states of the Mexican Republic. The evaluation sites were georeferenced, and incidence was estimated along with the farmers to determinate the identity of the germplasm used. Monkey´s hand was found affecting maize plants in localities of the States of Puebla with an incidence of 24%, Hidalgo (17.05%), Morelos (11.7%), Chiapas (7.28%), Tlaxcala (7.0%), Oaxaca (6.5%), Veracruz (6.3%), Mexico (6.2%), and Jalisco (3.0%). Data showed a low but positive correlation (r= 0.30) between altitude and incidence. Native germplasm is more susceptible to the monkey´s hand disease than improved germplasm.

Palabras llave : monkey’s hand; maize diseases; bouquet ears.
