Evaluación in vitro de la capacidad antagonista de Trichoderma harzianum y Pseudomona fluorescens frente a Phytophthora infestans, agente causal de tizón tardío en la papa (Solanum tuberosum L.)

Abstract:

The following study consisted on evaluating the antagonistic capacity of Trichoderma harzianum and Pseudomona fluorescens against Phytophthora infestans causative agent of Late blight on the potato. The speed of development of the pathogen was evaluated as well as the inhibition percentage of radial growth of the pathogen against the antagonist microorganisms working individually and simultaneously.
