Abstract

Turfgrass is one of the most important greenspace plants in cities that reduce dust in the runways and prevent wind and water erosion. One of the most important diseases in turfgrass is Fuarium decay of crown and root. In order to isolation of the causal agent of disease the samples collected from greenspace in different areas of Ardabil city. Root and crown were surface-sterilized using Sodium Hypochlorite 0.5%, and rinsed in sterilized distilled water. Then cultured on PDA medium. In order to identify the species of Fusarium PDA and SNA media were used. Based on morphological characteristics and authentic mycological keys, Fusarium equsti, F. solani, F. graminearum, F. sambucinum and F. acutatum were identified. Most of these species have been introduced as turfgrass pathogens from Iran and the world. F. acutatum is reported for the first time from turfgrass in the world. Awareness of the factors associated with Fusarium decay of crown and root of turfgrass and planning for its management can be effective in turfgrass freshness and health.
