Abstract: The study is carried out in Elazig province betweenthe years 2012-2014 with the prevalence of fungal disease in tomato fields andin order to determine the severity of the disease. Surveys were carried outbetween March and September, from the beginning seedling planting, inGedikyolu, Salkaya and Sarıkamış in Elazıg Center, Akmezra in Kovancılar andGemici villagers in Baskil, a total of 4.852 decare in area were realized in 5villages. Pure isolates of fungi from diseased tomato leaves were obtained anddiagnosed. In addition, prevalence rates and disease severity values of fungaldisease agents were also determined in the cultivation areas of tomatoessurveyed. As a result of isolation studies;387 isolates were obtained from 642tomato plant samples and 14 fungal pathogens were diagnosed. The prevalencerate of fungal disease agents in tomato roots according to survey studies; Rhizoctonia solani (20.27%), R.tuliparum (19.40%), Fusarium solani(17.42%), Colletotrichum coccodes(16.66%), Rhizopus stolonifer(13.79%) and Phoma destructiva(11.96%) was determined as. The prevalence rate of fungal disease agents on thetomato leaves; Alternaria alternata(27.23%), Septoria lycopersici (25.27%),Leveillula taurica (19.44%), Stemphylium solani (17.81%), Botrytis cinerea (17.39%), Phytophthora infestans (15.70%), Cladosporium fulvum (11.23%) and Ulocladium atrum (6.27%) was determined.Severity of fungal disease agents in tomato roots; R. solani (43.3%), R.stolonifer is (38.1%), F. solani(37.1%), P. destructiva (33.7%), C. coccodes (15.9%), R. tuliparum (14.7%) have beendetermined. Severity of fungal disease agents on the tomato leaves; A. alternata (47.5%), S.solani (40.1%), C. fulvum(29.9%), S. lycopersici (25.0%) B. cinerea (22.2%), P. infestans (21.0%), U.atrum (17.3%) and Leveillula taurica(17.1%) was determined. As a result; the average prevalence rate of fungaldisease agents 17.67% and average fungal disease severity 28.66% was determinedin tomato planting areas Elazig province. The most common fungal disease agentshighest prevalence rate of in tomato planting areas of Elazig are A. alternata, R. solani and L. taurica. The most common fungaldisease severity of was determined as A.alternata, R. solani and S. solani.
