Özet:

Field bindweed (Convolvulus arvensis L.) is a perennial, noxious weed in Europe and in many agricultural areas of the world, including Turkey. Some pathogenic fungi were identified as potential to control bindweed and some of them could be used as mycoherbicide components. In the summer of 2008, 2009 and 2010 the diseased bindweed plants were collected from different sites of Amasya, Ankara, Çorum, Samsun and Tokat provinces. Pathogenic fungi were isolated from diseased plants and they were identified based on their morphological characteristics. Bindweed plants were grown in a climatically controlled room to the 4 to 5-leaf stage; they were inoculated with an aqueous spore suspension of each fungi at various densities specified. Spores were sprayed onto bindweed plants with a hand sprayer until runoff. Dates were recorded for each isolate when disease lesions became visible, and the proportions of diseased leaves, out of the total number of leaves, on each inoculated plant were recorded. Stagonospora convolvuli, Colletotrichum linicola and Myrothecium verrucaria produced the highest level of diseases on the inoculated test plants. Plant heights of C. arvensis were recorded the shortest following inoculation with C. linicola and a Phoma sp. These results indicate that, C. linicola seems potentially effective and field tests alone or in combination with S. convolvuli, should be performed
