ABSTRACT: Maize is the main crop for Mexicans; however,
it is affected by species of fungi causing ear rot. This research aimed to
evaluate the effect of T. asperellum T11, T. harzianum T1 4 y T.
longibrachiatum T1 40 on some agronomic variables of four maize genotypes.
The seeds of the genotypes H-515, Zapata 7, and H-507 were treated with a
suspension of Trichoderma spp. to 1 × 108 spores mL-1,
using a control (untreated seed), and Benomyl as chemical control. The planting
was in Morelos, in a completely random block design with a factorial
arrangement. The ear rot was natural. Data were obtained at the end of the crop
cycle and processed in SAS 9.4®. H-515 genotype had the greatest effect on the treatment of maize seeds with Trichoderma spp. (5.562 kg); T. asperellum T11 was the strain that stood out with a mean yield of 50 ears in an area
of 16 m2 of 4.904 kg, and control of 4.448 kg. Our results are an
economic option for farmers to contemplate the use of Trichoderma and
obtain its benefits.
