Default Re: Bsv?

I see you have quite a few bananas with similar patterning on the leafs. Are they relatively close together? Did you ever see mealy bugs on those bananas? Were they stressed in any manner prior to symptom appearance?
The answers to the above questions actually will still not be any more conclusive unfortunately but would help some when compared all together. The above are ways BSV is transmitted and ways its hidden genome is activated. On the other hand,variegation is also supposed to be caused by some kind of stress or random mistake during cell multiplication in part of the meristem.

I think we really need a banana pathologist's help and expert opinion if we are to find out what this is. A virus indexing would be the ultimate way to rule out virus and if we do a leaf analysis we could also check the chance of a nutrient deficiency causing it. If only i could find a lab able to do the virus indexing...
