Occurrence of Cladosporium herbarum on wheat leaves (Triticum aestivum) in Argentina

Abstract

During the course of recent surveys in the wheat cropping area of Buenos Aires and Entre Ríos Provinces, Argentina, an unusual disease was found on wheat leaves. A fungus was isolated from the symptomatic tissues and identified as Cladosporium herbarum (Pers.:Fr) Link. Inoculations were carried out under greenhouse conditions to test pathogenicity and fulfil Koch's postulates. The symptoms of the disease and the causal agent are described.
