The main viticultural production areas in the Republic of North Macedonia were surveyed in 2006/2007/2008 for the presence of grapevine yellows. PCR and RFLP analyses were used to detect and identify phytoplasmas infecting grapevines. Only phytoplasmas associated with “bois noir” disease (ribosomal subgroup 16SrXII-A or stolbur) were ...
The disease is caused by a single-stranded circular DNA virus, the species grapevine red blotch virus, also known as grapevine red blotch-associated virus, GRBaV. [1] First identified in California, the disease affects grapevines of all varieties and is internationally present. Symptoms typically include red blotches on the leaves of red ...

The grape black rot pathogen overwinters in many parts of the grape vine, especially mummies and lesions, and is able to overwinter on the vineyard floor. [3] In fact, "Viable lesions capable of producing conidia can persist in wood for at least 2 years."

Phomopsis cane and leaf spot is a disease that causes symptoms in the common grapevine species, Vitis vinifera, in many regions of the world. [2] This disease is mainly caused by the fungal pathogen, Phomopsis viticola, and is known to affect many cultivars of table grapes, such as Thompson Seedless, Red Globe, and Flame Seedless. [3]
