Abstract :

To study the role of Pythium species as the turf pathogenic agents, during the years 2005 and 2006, diseased samples and soil samples from green spaces and sport fields were collected from different regions of Tehran province. From isolates identified, Pythium catenulatum Matthewshas been reported from turfgrasses in other countries, but our study is the first report of this species in Iran. Pythium okanoganense Lippshas been isolated from soil in Iran but hasn’t been recorded from turfgrasses in Iran and other countries yet.
