No, there is currently no evidence that rose mosaic virus spreads from plant to plant in a garden setting.
While much research has been conducted, rose mosaic virus (RMV) is primarily transmitted through propagation methods like grafting and budding. This means the virus is spread when infected plant material is used to create new rose plants.
Here's a breakdown of why direct spread is considered unlikely:
- Lack of Evidence: Extensive research has not found a vector (like an insect) capable of transmitting the virus between plants.
- Grafting as the Primary Mode: The documented cases of RMV transmission are overwhelmingly linked to the use of infected budwood or rootstock during propagation.
Therefore, the main concern with rose mosaic virus is preventing its introduction through infected nursery stock. Selecting healthy, virus-free roses from reputable sources is the best preventative measure. If you have a rose with suspected RMV, it's unlikely to infect nearby roses, but it's important to consider the health and aesthetic impact on the infected plant itself.
