Leptosphaeria herpotrichoides

Leptosphaeria herpotrichoides is a species of fungus that belongs to the Leptosphaeria genus. It is known for causing diseases in cereal crops, particularly wheat, and is commonly referred to as the causative agent of Eyespot.

Taxonomy

The fungus was first described in 1927 by the mycologist Hans Wilhelm Wollenweber. It belongs to the Leptosphaeria genus, which comprises over 600 species of fungi. The species name herpotrichoides is derived from the Greek words herpo (to creep) and trichos (hair), referring to the creeping, hair-like growth of the fungus.

Description

Leptosphaeria herpotrichoides is a filamentous fungus. It produces hyphae, which are long, branching structures that are characteristic of fungi. The hyphae of L. herpotrichoides are septate, meaning they contain cross-walls. The fungus also produces conidia, which are asexual spores that are involved in the dispersal and infection process.

Pathogenicity

Leptosphaeria herpotrichoides is a plant pathogen, causing a disease known as Eyespot in wheat. The fungus infects the stem base of the plant, causing lesions that can lead to lodging and yield loss. The disease is most severe in cool, wet conditions.

Management

Management of L. herpotrichoides involves a combination of cultural practices, such as crop rotation and tillage, and the use of fungicides. Resistant cultivars of wheat are also available, which can help to reduce the impact of the disease.
