Linochora graminis is a species of fungus in the family Erysiphaceae. It is a plant pathogen that primarily affects grass species.

Taxonomy

The species was first described in the scientific literature by the mycologist Petrak in 1953. It belongs to the genus Linochora, which comprises around 10 species of fungi. The species name graminis is derived from the Latin word for grass, reflecting the primary host of this pathogen.

Description

Linochora graminis is a powdery mildew fungus, characterized by its white, powdery growth on the surface of infected plants. The fungus produces conidia (asexual spores) that are spread by wind to new hosts.

Distribution and habitat

Linochora graminis has a wide distribution and has been reported in various parts of the world. It is typically found in grassy areas, including meadows, pastures, and lawns. The fungus prefers humid conditions and is most active during the warm months of the year.

Pathogenicity

As a plant pathogen, Linochora graminis can cause significant damage to grass species. Infected plants display symptoms such as white, powdery patches on the leaves and stems, yellowing of the foliage, and reduced growth and vigor. In severe cases, the fungus can cause the death of the host plant.

Management

Management of Linochora graminis involves a combination of cultural practices and chemical control. Cultural practices include maintaining optimal plant health through proper watering and fertilization, and removing and disposing of infected plant material. Chemical control involves the use of fungicides that are effective against powdery mildew fungi.
