Study of fungi associated with metropolitan waste water used for irrigation on soil in sokoto was carried out within sokoto metropolisusing culture method, microscopic and biochemical identification. Water samples were collected from the upstream, midstream and down stream section of the stream while three soil samples each were collected adjacent to the water sampling sites using Random sampling technique. The samples were aseptically collected in sterilized bijour bottles and are transported to the Microbiology Laboratory of the Department of Natural Sciences of the Polytechnic of Sokoto State for analysis. Soil samples within the study area were found to be loamy-sand and the texture was moderately bulky in density(1.70g). The predominantly isolated fungal pathogens wereAspergillusniger (26.8%) Rhizopus stolonifer (20.1%),Mucur racemosus (17.2%) and the least in occurence were Penicilliumcitrinum and Aspergillusfumigatuswith (11.8%) each. It can therefore be concluded that the waste water used in irrigating the soil contributes to the contamination of the irrigated soil with fungal pathogens mentioned earlier. The study recommends that farmers should be enlightened on the need to purify the waste water prior to use and other ameliorating measures to reduce risk of contaminationshould be imposed by the authorities in the study area.
