The genus Helminthosporium includes species that produce dark, elongated spores, often with a helical twist. The spores are typically multicellular and have a dark, thick wall. The fungi grow as filamentous, branching hyphae that can produce asexual spores (conidia) on specialized structures called conidiophores.

Pathogenicity

Species of Helminthosporium are known to cause diseases in a variety of plants. They are particularly notorious as pathogens of cereal crops, such as wheat, barley, and corn. The diseases caused by these fungi can lead to significant yield losses. Symptoms of infection can include leaf spots, wilting, and blight.

Management

Management of Helminthosporium diseases involves a combination of cultural practices, chemical control, and the use of resistant varieties. Cultural practices can include crop rotation and the removal of infected plant debris. Fungicides can also be used to control the fungi.
