Özet

Quantitative disease surveys were conducted to evaluate the distribution and incidence of the fungal disease agents causing root-foot rot and foliar diseases on bean (Phaseolus vulgaris L.) plants in major bean growing districts of Hatay province of Turkey. The disease surveys were conducted, during the period of February to June 2006, in randomly selected bean fields at three major plant growing stages such as seedling stage, flowering stage and fruiting-harvesting stage. The results of fungal isolations from diseased bean roots, crowns and stems taken at regular intervals over the entire growth period indicated that the most frequently encountered and widespread soil-borne fungal disease agents were Fusarium solani (Mart.) Sacc. f. sp. phaseoli (Burkholder) W. C. Snyder & H. N. Hans. [Fusarium root rot]; Fusarium oxysporum Schlechtend Fr. f. sp. phaseoli J. B. Kendrick and W. C. Snyder [Fusarium wilt]; Rhizoctonia solani Kuhn. [Rhizoctonia root rot]; Macrophomina phaseolina (Tassi) Goidanich [Charcoal rot]; Pythium ultimum Trow [Pythium disease]; Sclerotinia sclerotiorum (Lib.) de Bary [White mold]; Sclerotium rolfsii Sacc. [Southern blight] and Alternaria spp. on bean plants growing in all districts surveyed. Majority of the affected seedling samples were infested by more than one disease agents. Alternaria leaf spot caused by Alternaria altemata (Fr.) Keissler and bean rust caused by Uromyces appendiculatus (Pers.) Unger var. appendiculatus were the most frequently observed foliar fungal disease agents at both flowering and fruiting-harvesting stages of bean plants. Podosphaeraphaseoli (Zhao) U. Braun [Powdery mildew] and Phaeoisariopsis griseola (Sacc.) Ferraris [Angular leaf spot] were the least frequently observed foliar fungal disease agents at this stage.
