In vitro antagonic capacity evaluation of Trichoderma spp strains against Phytophthora cinnamomi, phytopathogen of Persea americana (Palta)
Descripción del Articulo
Phytophthora cinnamomi is a phytopathogen reported as the causative agent of avocado root rot in Peru. In this study, the antagonistic capacity of Trichoderma spp native strains isolated from the avocado crop rhizosphere in Quilmaná, Cañete, was evaluated. For the in vitro evaluation of the antagoni...

In this study, the antagonistic capacity of Trichoderma spp native strains isolated from the avocado crop rhizosphere in Quilmaná, Cañete, was evaluated. For the in vitro evaluation of the antagonistic capacity of the isolated strains, the dual culture technique was used, where the percentages of radial growth inhibition (PICR) of P. cinnamomi were measured. Of the total isolates, 3 strains (P1.1, P4.9 and P5.3) presented higher PICR with 53.86, 56.24 and 60.49% respectively. Molecular identification indicated that strains P4.9 and P1.1 show 99.66 and 100% similarity to Trichoderma asperellum, while strain P5.3, 98.17% similarity to Trichoderma spp, according to BLAST analysis. Based on the results obtained, these Trichoderma asperellum strains represent a potential to be used as biocontrol agents of P. cinnamomi. therefore, it is recommended to carry out a field trial.Phytophthora cinnamomi es un fitopatógeno reportado como el agente causal de la pudrición radicular del palto en el Perú. En este estudio se evaluó la capacidad antagónica de cepas nativas de Trichoderma spp aisladas de la rizósfera de un cultivo de paltos del distrito de Quilmaná, Cañete. Para la evaluación in vitro de la capacidad antagónica de las cepas aisladas se utilizó la técnica de cultivo dual en donde se midió los porcentajes de inhibición del crecimiento radial (PICR) de P. cinnamomi. Del total de cepas aisladas, 3 (P1.1, P4.9 y P5.3) presentaron mayores PICR con 53.86, 56,24 y 60,49 % respectivamente. La identificación molecular indicó que la cepas P4.9 y P1.1 presentan un 99,66 y 100% de similitud con Trichoderma asperellum mientras que la cepa P5.3 un 98,17% de similitud con Trichoderma spp, según el análisis BLAST. En base a los resultados obtenidos estas cepas de Trichoderma asperellum representan un potencial para ser utilizadas como agentes biocontroladores de P. cinnamomi. por lo que se recomienda realizar ensayo en campo.Universidad Nacional Mayor de San Marcos, Facultad de Farmacia y Bioquímica2020-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/farma/article/view/1875410.15381/ci.v23i1.18754Ciencia e Investigación; Vol. 23 Núm. 1 (2020); 65-70Ciencia e Investigación; Vol. 23 No. 1 (2020); 65-701609-90441561-0861reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/farma/article/view/18754/15796Derechos de autor 2020 Ebeling M.
