ABSTRACT: Orchidaceae is the plant family with the largest number of species on the planet, Brazil has a rich diversity of species, with emphasis on the Southern Amazon region. Orchids have high economic value because they present floral beauty, with diversity of shapes and colors, and in general the cultivation is rustic. However, these characteristics can be compromised by the incidence of diseases. The identification of pathogens in orchids is still little explored, researches associated with this area are important, as they can contribute to the adequate management of diseases that occur in orchids, favoring the control of pathogens. In this context, the objective was to isolate and identify phytopathogens in orchids with characteristic symptoms. Three genera of microorganisms harmful to orchids were isolated and identified, two of fungal etiology, Colletotrichum sp. present in the following orchid species Dendrobium sp., Maxillaria pouciflora, Oncidium baueri, Schonburgkia marginata, Zigosepalum labiosum. The pathogen Lasiodiplodia sp. was found in the species Schonburgkia marginata. And the pathogen of the genus Pythium sp. (Chromist kingdom) was observed in the species Maxillaria pouciflora. KEYWORDS: Plant diseases, Orchid species, Phytopathogens.
