Stagonosporopsis

Stagonosporopsis is a genus of fungi within the family Didymellaceae. This genus is known to cause various plant diseases, particularly in the grapevine species.

Taxonomy

The genus Stagonosporopsis belongs to the family Didymellaceae, order Pleosporales, class Dothideomycetes, phylum Ascomycota, and kingdom Fungi. The genus was first described by the mycologist Hans Sydow in 1915.

Description

Species within the Stagonosporopsis genus are characterized by their production of conidia, which are asexual spores. These conidia are typically hyaline, smooth, and have a septate structure. The conidiophores, structures that bear the conidia, are often branched and septate as well.

Pathogenicity

Stagonosporopsis species are known to be pathogenic, causing diseases in various plant species. One of the most notable diseases caused by this genus is Black rot in grapevines, caused by Stagonosporopsis viticola. This disease can lead to significant yield losses in vineyards if not properly managed.

Management

Management of Stagonosporopsis diseases involves a combination of cultural practices and chemical control. Cultural practices include pruning and removal of infected plant material, while chemical control typically involves the use of fungicides.
