The Beneficial Effect of <i>Trichoderma</i> spp. in Seed Treatment of Four Maize (<i>Zea mays</i> L.) Genotypes

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