    11 ABSTRACT Ph.D.Thesis RESEARCHES ON THE CONTROL MEANS OF FUSARIUM WILT OF MELONS (Fusarium oxysporum Schlecht f.sp. melonis Snyder and Hansen) BY INDUCED RESISTANCE Kudret ERZURUM Ankara University Graduate School of Natural and Applied Sciences Department of Plant Protection Supervisor: Prof.Dr. Salih MADEN 1993, Page:75 Jury: Prof. Dr. Salih MADEN Prof.Dr. Gürsel ERDÎLLER Prof.Dr.Hafiz DELEN Applicability of induced resistance by trifluralin and microorganisms aganist Fusarium Wilt of melon on Yuva cv. caused by race 1.2 was evaluted. Application of trifluralin at the rate of 0.5 and 1.0 (ig/g to seeds and soil decreased the disease incidence 21.5, 12.9, 39.8 and 52.0 % respectively after 36 days of inoculation. Seed applications of the two isolates of non-pathogen Fusarium oxysporum [(18)2 and (9)i) and two formae speciales of it (f.sp. lycopersici and f.sp. niveum) yielded 47.3, 38.1, 29.3 and 32.1 % reduction in disease incidence while root applications of them gave 45.3, 40.1, 32.8 and 31.3 % reduction. Localised leaf infections of the first true leaf of melon by Colletotrichum lagenarium did not protect the plants against the disease while treatment of melon seed with culture filtrates of it gave 29.5 % disease protection. KEY WORDS: Induced resistance, muskmelon, Cucumis melo, Fusarium Wilt, Fusarium oxysporum f.sp. melonis, race.
