| Deskribapena: | Vanilla sp. genus belongs to Orchidaceae family, and V. planifolia, V. pompona and V. tahitensis. are species of commercial interest. The quality classification of vanilla is made according to the length of the capsule and vanillin content, which is used to make food and beverage, as raw material in the pharmaceutical industry and for the production of cosmetics and perfumes, among others. Currently, root rot caused by the fungus Fusarium oxyporum f. sp. Vanillae is considered to be the biggest problem facing vanilla production, causing 30 to 52% of plant death, attacking adventitious roots and preventing this plant is able to absorb water and nutrients. The fungus cannot be eradicated by the action of chemicals that damage the viability of the plants, and because the cultivation of vanilla in agroforestry systems without the application of agrochemicals is an activity that is gaining interest among small producers country. It is for this reason why was studied the ability of control of vanilla endophytic bacteria isolated from samples from Corcovado, Puriscal, Dota and Guápiles, by testing in vitro antagonism between asylee bacteria and fungus F. oxysporum, giving results about promising candidate B1M11 to respond to pathogen attack, which was corroborated by the appearance of a halo of inhibition of fungal growth on plate. |
