Abstract

The onset of some sclerotic formations are reported on barley straws on which the following microscopic investigations and biometrical measurements peritecia, ascia and ascospores of Pyrenophora graminea (Rabh. Ito et Kurib.) were detected, representing the sexed multiplication of fungus Helminthosporium gramineum, the pathogenic factor causing leaf tearing in barley, a condition rarely encountered in nature. Owing to the great number of peritecia on barley straw residues, we are of the opinion that the sexed multiplication of fungus represents a real danger in barley cultivation assigning the efficient control steps against this pest.
