Tapesia Yallundae Walwork & Spooner, Cause of Eyespot Disease of Wheat and Barley in the Republic of Macedonia
Abstract
During the period 2006 - 2009, the occurrence of “eyespot” symptomsin wheat (Triticum aestivum) and barley (Hordeum vulgare L.) plants wasnoticed in the region of Pelagonia, Probistip, Skopje, Resen and Prilep. Thissymptom is caused by the plant pathogen fungus Tapesia yallundae Wallwork& Spooner and the аnamorphic stage Pseudocercosporella herpotrichoides(Fron) Deighton. Symptoms observed are diffuse eyespot lesions developedon the stem base. Microscopic observations and laboratorial investigationshowed the presence of teleomorphic and anamorphic stage of this pathogen.The presence of the anamorphic stage Pseudocercisorella herpotrichouides(Fron) Deighton is confi rmed with the microscopic observation of long andtight hyaline conidia and conidiophores growing on septed, light olivaceousmycelium, while the presence of the teleomorphic stage Tapesia yallundaeWallwork & Spooner is confi rmed with the presence of apothecia containing alot of asci with eight ascospores.References
