Grapevine fanleaf virus

[3] This nematode acquires the virus through feeding on roots of an infected plant, and passes it on in the same manner.

The leaves will be “severely distorted, asymmetrical, cupped and puckered, and exhibit acute dentations”, these symptoms tend to look like a fan, hence the name fanleaf virus.

The canes may also show signs of abnormal branching, double nodding, and short internodes.

Another prevention method is the disinfect the pruning tools between each plant to help reduce the amount of disease spread from humans.
