Abstract :ABSTRACT This search is carried out in order to find out the causes and ratio of drying on turfgrass in Konya. In the process of the research, surveys on the green areas were held between the years 2003 and 2004. As a consequence of these surveys, it is determined that the factors causing drying of the turfgrass on the green areas in Konya are originated from abiotic and biotic reasons. Where as delayed reaping deficiency of phosphorus, human causing harm, insufficient or excessive irragation, using scythe to cut the grass and the indirect harms of cutting machines have been accepted as the biotic factors resulting in drying on turfgrass, Fusarium culmorum, Fusarium equiseti, Fusarium oxysporum, Fusarium solani, Rhizoctonia solani, Pythium sp. and Dreschlera sp. have been considered as biotic based reasons. It is observed that there is drying on 33 different turfgrass locasion due to both abiotic and biotic reasons. Mean while, the ratio of the dried areas to the total turfgrass areas was recorded as 0.62 % in 2003 and as 0.77 % in 2004. The general dry-ing ratio was found as % 0.69. As a result of isolation made to determine the biotic results of drying, 6 species belonging to 17 different genus have been identified. As a consequence of pathogenicity tests on seven of these fungi, it was found that all these seven species are pathogen. According to these pathological tests, the severity of diseases on turfgrass are measured as as 99.4 %, 99.22 %, 98.95 %, 94.77 %, 93.02 %, 67.40 % ve 62.90 %. These measurements respectively belong to Fusarium culmorum, Fusarium solani, Fusarium oxysporum, Rhizoctonia solani, Dreschlera sp., Pythium sp., Fusarium equiseti.Keywords : Abiotik, Biotik, Çim, Konya, Kuruma
