[Evaluation of Trichoderma spp. as antagonist of Rhizoctonia solani in vitro and as biocontrol of greenhouse tomato plants].
Five Trichoderma isolates were compared in their ability for controlling Rhizoctonia solani attack to tomato plants in greenhouse and as antagonists of this pathogen in three independent laboratory assays. Four out of five isolates showed biocontrol ability and decreased pathogen growth and survival of its sclerotia in soil. Results suggest that dual cultures in Petri dishes and mycoparasitism assays against R. solani sclerotia may be useful for detecting isolates effective as biological control agents against this pathogen in tomato plants.
