Cladosporium Spot of Barley

Hordeum vulgare L.

The term "Cladosporium spot" in relation to barley is not a generally accepted agronomic name for a pathology. Fungi of the genus Cladosporium on this crop more often act as saprotrophs, causing "black head mold" under high humidity conditions rather than as pathogens of specific leaf infections.

In the reference 3 varieties crop Barley, where this is mentioned in the description.

In scientific literature, fungi of the genus Cladosporium are recorded on barley as saprotrophic organisms that develop on mature ears along with Alternaria, leading to the appearance of a growth known as black head mold. Although there are isolated cases of detecting Cladosporium allicinum fungi on leaves, this is not classified as a systemic agricultural problem for barley.

In agronomic practice, symptoms mistakenly identified as Cladosporium spot are usually associated with the crop's profile diseases, such as net blotch, spot blotch, or stripe disease, as well as scald. Due to the lack of a specialized pathosystem in barley, there are no generally accepted rating scales or breeding resistance genes specifically for Cladosporium spot.
