Doğu Akdeniz bölgesi örtü altı domates yetiştiriciliğinde Fusarium oxysporum spesiyal formlarınının simptomatolojik ayrımı ile solgunluk ve kök-kök boğazı çürüklüğü hastalıklarının çıkış, şiddet ve yaygınlıklarının belirlenmesi

Abstract

Fusarium crown and root rot and Fusarium wilt are the most important diseases of tomato grown under protected conditions in the Eastern Mediterranean region of Turkey. The diseases cause important economic losses in the region. Survey studies were conducted in tomato growing greenhouses of Adana and Mersin provinces to determine disease incidence and severity of Fusarium crown and root rot (FORL) and Fusarium wilt (FOL) during November 2007-April 2008. Disease incidence and disease severity values were 35.1% and 18.8% in Adana province and 43.3% and 20.4% in Mersin province, respectively. Disease prevalence in terms of number of diseased greenhouses and diseased area were 56.1% and 68.1 in Adana province and, 58.8% and 54.5% in Mersin province, respectively. As a result of pathogenicity studies, symptomatologic characters of different regions according to the determination of the 87 isolates 61 (70%) FORL and 26 (30%) isolates were identified as FOL, respectively.
