What is the primary host for the grape fanleaf nepovirus?

The grape fanleaf nepovirus primarily affects grapevines, making grape the primary host for this pathogen. This virus can significantly impact grape production, leading to reduced yield and quality. Understanding that grapevines serve as the main reservoir for this virus is crucial for effective management and control strategies in vineyards. In contrast, while other fruit trees like cherry, apple, and peach may have their own associated pathogens, they are not considered primary hosts for the grape fanleaf nepovirus, as this virus is specifically adapted to infect grapevine species.
