"Biocontrol de Fusariumm solani Mart a base de trichoderma spp., en el cultivo de maracuyá (Passiflora edulis) VAR. Flavicarpa in situ"

passion fruit, results in death associated with the presence of the fungus Fusarium solani Mart production units. In order to contribute to the management of the health problem, was evaluated under field conditions the effect biocontrol two commercial inoculants prepared from mixtures of various species of Trichoderma (T. harzianum + T. asperelleum) and (T. viride, T. koningii, T. harzianum + T. polysporum) respectively. Plants four months old, implanted in the field, where a trial in which the plants were inoculated with the pathogen and seven days after the antagonist was applied under an experimental design of randomized complete block design was established where the results were used subjected to analysis of variance (ANOVA) and comparison of means was performed using the Tukey test. Chemical control with the use of Carbendazim 500 g / l and commercial inoculants for T1, T2 and T3 respectively plus a control treatment that the pathogen was inoculated only: three treatments of application is evaluated. Could antagonize check Trichoderma strains present in the commercial products, and the mixture of strains T.viride; T. koningii; T. harzianum and T. polysporum who demonstrated progress control of the pathogen within the plant and a significant reduction of its activity, also proven by a remarkable root development of the plants affected by the disease, due to the symbiotic activity exercised Trichoderma, demonstrating to obtain greater root biomass and volumes in the root zone KEYWORDS: Passiflora edulis, biological control, Fusarium solani Mart, antagonism, field conditions.
