Evaluation of Trichoderma in Three Peanut Varieties (Arachis hypogaea L.)
Bearing in mind that peanut cultivation in Ecuador has lost agricultural interest due to its susceptibility to fungal diseases, and that the application of microorganisms of the genus Trichoderma effectively controls other species of pathogens, we decided to carry out this study.

| description | Bearing in mind that peanut cultivation in Ecuador has lost agricultural interest due to its susceptibility to fungal diseases, and that the application of microorganisms of the genus Trichoderma effectively controls other species of pathogens, we decided to carry out this study. For this, the Plant Health Laboratory and the experimental area of “Santa Inés” farm of the Faculty of Agricultural Sciences at the Technical University of Machala were used. A completely randomized block design was employed, with 33 treatments, four Trichoderma and its mix strains, two concentrations (1011 and 1012 spores/L) on three peanut varieties (INIAP 380, 381 and 382), three controls, with three replicates, evaluating 15 plants per dose, giving a total of 495 plants. The variables evaluated were plant height (cm), main branches/plant, 100 seed weight (g), nodule weight (g), number of seeds/pod, number of seeds/plant, number of pods/plant, seed weight per plant, rust incidence and white mold incidence. The results obtained indicated that the application of Mix increased production in all varieties and decreased the incidence of rust (Puccinia arachidis) by 55% and white mold (Sclerotinia sclerotiorum) by 53% compared to the controls. |

Tomando en cuenta, por una parte, que el cultivo de maní en el Ecuador ha perdido interés agrícola debido a su susceptibilidad ante enfermedades fúngicas, y por otra, que la aplicación de microorganismos del género Trichoderma controla eficientemente otras especies de patógenos, se decidió llevar a cabo este estudio. Para ello, se utilizó el Laboratorio de Sanidad Vegetal y el área experimental de la granja “Santa Inés” de la Facultad de Ciencias Agropecuarias en la Universidad Técnica de Machala. Se empleó un diseño de bloques completamente al azar, con 33 tratamientos, cuatro cepas de Trichoderma y la mezcla (Mix), dos concentraciones (1011 y 1012 esporas/L) en tres variedades de maní (INIAP 380, 381 y 382), tres testigos, con tres repeticiones, evaluando 15 plantas por dosis, con un total de 495 plantas. Las variables evaluadas fueron: altura de planta (cm), ramas principales/planta, peso 100 semillas (g), peso nódulos (g), número de semillas/vaina, número de semillas/planta, número de vainas/planta, peso de semillas por planta, incidencia de roya e incidencia de moho blanco. Los resultados obtenidos indicaron que la aplicación de Mix incrementó la producción en todas las variedades y disminuyó la incidencia de la roya (Puccinia arachidis) en un 55 % y del moho blanco (Sclerotinia sclerotiorum) en un 53 % en comparación con los testigos.
