Abstract :Fusarium wilt caused by Fusarium oxysporum Schlect f.sp. melonis (Leach &Currence) snyd.&Hans is the most im-portant disease of melon (Cucumis melo) in many countries, including Turkey. Konya is the major for melon plant field and production amongst the cities of Central Anatolia. Also Fusarium wilt is the most serious disease of melon plants in Konya Province. This study was carried out during 2000-2002 for determination of prevalence Fusarium wilt disease on melons and path-ogenicity of Fusarium species isolated from melon. For this purpose, field surveys were carried out in 2000 and 2001 and then pathogenicity experiments were conducted in 2002. According to field survey results; prevalence ratios of disease were found 72.05 % and 84.55 %, while ratios of infected plants were determined as 19.22 % and 33.36 % in 2000 and 2001 respectively. The following fungi were the most commonly isolated from root and crown of diseased melon plants: Fusarium spp. (67.32 %), Macrophomina phaseolina (18.07 %), Fusarium spp. and Macrophomina phaseolina are together (5.90 %), Alternaria spp. (2.39 %), Rhizoctonia solani (1.52 %), Pythium spp. and (1.2 %). A total of 249 Fusarium spp. isolates were obtained. Of these isolates 37.8 %, 32.6 %, 16.4 %, 11.4 % and 1.8 % were identified as F. oxysporum, F.equiseti, F. culmorum, F.solani and F. semitectum respectively. In pathogenicity experiments were used total 18 Fusarium spp. isolates (10 F. oxysporum, 3 F.solani, 3 F. equiseti and 2 F.culmorum). In the result of pathogenicity tests, only one F. oxysporum isolate was found more virulent (95.83 %) than other Fusarium isolatesKeywords : Fusarium solgunluğu, kavun, patojenite, yaygınlık
