Sooty blotch and flyspeck (SBFS) is a mid- to late-season fungal disease complex that blemishes apples and other tree fruit crops in humid regions worldwide. SBFS is a concern for apple growers in northeastern Turkey, but the composition of the SBFS species assemblage in Turkey is unknown. In this study, SBFS fungi were isolated from apples collected in(More)
Scleroramularia is proposed as a new hyphomycetous fungal genus associated with sooty blotch and flyspeck (SBFS) blemishes of apple and pawpaw fruit in the Northern Hemisphere. Morphologically the genus closely resembles Ramularia (Mycosphaerellaceae), based on its chains of hyaline conidia, with thickened, darkened, somewhat refractive conidiogenous loci.(More)
Botrytis cinerea infection of kiwifruit was reported for the first time from Rize, Turkey. The pathogen caused leaf blights. It is found in Rize central district, Ardesen, Pazar, Çayeli, Fındıklı and Güneysu districts. Isolates were confirmed to be B. cinerea using polymerase chain reaction with specific primers C729± that amplified a 700 bp fragment.
An extensive survey was carried out to collect Fusarium species colonizing the lower stems (crowns) of bread wheat (Triticum aestivum L.) and durum wheat (T. durum Desf.) from different wheat growing regions of Turkey in summer 2013. Samples were collected from 200 fields representing the major wheat cultivation areas in Turkey, and fungi were isolated from(More)
The reactions of 36 barley cultivars and 683 barley genotypes to scald were investigated under greenhouse (seedling) and field (adult plant) conditions. Among the 683 barley genotypes tested 44% and 39 % were found to be resistant to moderately resistant in the seedling and adult plant stage, respectively. In the genotype resistance study, a significant(More)
Passalora blight of anise, caused byPassalora malkoffii (Bubák) U. Braun, is an important disease of anise in Turkey. The disease affects all the aboveground parts of plants including flower clusters. Infected seeds have dark, linear stromata. Detection of the pathogen on seeds was studied by the blotter method, agar method, washing test and sowing infected(More)
Seedling reactions of 15 barley cultivars grown in Turkey were determined under greenhouse conditions to five isolates of Drechslera graminea, the causal agent of barley stripe disease. Isolates were collected from different parts of Ankara province. Differences were observed among the reactions of the cultivars to the isolates of the fungus. There were(More)
