Allorhizobium vitis is a plant pathogen that infects grapevines.The species is best known for causing a tumor known as crown gall disease. [5] One of the virulent strains, A. vitis S4, is responsible both for crown gall on grapevines and for inducing a hypersensitive response in other plant species. [6]
Cultural practices and fungicide use are two methods that grape growers use to reduce P. tetraspora.Removing leaf litter, increasing air circulation over the soil surface and canopy space, and removal of susceptible hosts from the immediate environment are some cultural practices that can help control P. tetraspora development.
Specifically, E. ampelina affects blackberries, raspberries, mountain grapes, fox or concord grapes, and the European wine grape. Anthracnose diseases can cause disease on a variety of plants, but the primary host for E. ampelina, is grape. [3] Anthracnose on grape presents itself as lesions on shoots, leaves, and berries.

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 ...
