CORRALES RAMIREZ, Lucía Constanza; SANCHEZ LEAL, Ligia Consuelo e QUIMBAYO SALAMANCA, Melco Esteban. Potentially phytopathogenic microorganisms irrigation water from the media Bogota river basin. Nova [online]. 2018, vol.16, n.29, pp.71-89. ISSN 1794-2470.
Objective.
Identify phytopathogenic microorganisms present in the water used for irrigation in the middle basin of the river Bogota.
Methods.
Samples were taken at 12 farms of the middle basin and analyzed by the membrane filtration technique. The bacteria were identified by biochemical and fungi by dichotomies keys.
Results.
The irrigation water contained bacteria analyzed as E. coli, P. vulgaris, A. urinae, E. cloacae, B. cereus, S. marcescens, B. brevis, and as for the mushrooms found: A. fumigatus, A. flavus, Mucor sp., Rhizopus sp., Penicillium sp. and Fusarium sp. The presence of these potential pathogens in water indicate a high risk of contamination and dispersion thereof in crops.
Palavras-chave : Irrigation water; wastewater; plant pathogens; middle basin.
