Sp. Passifloracea, in passion fruit, measuring the efficiency of Application of the antagonistic fungus Trichoderma sp in the management of the disease and determining the effect of plant extracts based on Ruta de gallinazo (Ruta graveolens) and nettle (Urtica dioca) on infection caused by F. oxysporum F. Sp. Passifloraceae, in passion fruit. The research was carried out in the Greenhouse and in the Laboratory of Phytopathology and Microbiology of the Quevedo State Technical University in which both the variety of yellow and red passion fruit inoculated with F. oxysporum were studied, the same ones that were treated by means (Trichoeb: antagonistic fungi), extracts from Ortiga (U. dioica) and Ruda (R. minuta), Captan (Chemical Control-Carboximide). Two controls were used, one inoculated with F. oxisporum and the other without inoculation. The design used was Complete Blocks to Random (BCA) for in vitro evaluations and factorial arrangement for the greenhouse test. The experimental unit consisted of five plants / treatment and for the separation of means of treatments the Duncan test at 0.05% was used. The variables that were recorded in greenhouse were plant death (MP), length of vascular lesions (TLV-cm) and root weight (PR-g); And the level of inhibition of radial growth (ICM) and sporulation (PIE) was determined at the laboratory level. According to the results, the variety of yellow passion fruit had the lowest average of dead plants; Although its behavior was similar to the red variety in the other variables recorded. Among the means of control it was observed that Trichoderma had a broad control over F. oxysporum F. Sp. Passifloraceae, inhibiting the fungus activity at growth and reproduction level. Vegetable extract based on Nettle (U. dioica) was the most effective in inhibiting the mycelial growth of this fungus. Keywords: Fusarium. Oxysporum, plant extracts, antagonist, passion fruit |
