My Mysore has BSV, and I want to remove it and put a Pisang Klotek in the same spot. Can the BSV transmit through the soil, maybe from old root fragments, and infect the PK?

Hi,

As far as I know and have experienced, transmission is usually by vector or by new episomal virus derived from integrated virus on the unbalanced B genome (e.g.: AAB, AAAB, AB) cultivars and experimental hybrids. BB (balbisiana diploid) tend to be immune...

So I'd say, it isn't likely. Why not thoroughly deep till the old mat; giving roots a few weeks to die; and then replant?

I think that would work great. The BSV originally came about from stress because it is integrated into Mysore's genome. Pisang Klotek is a virus-free variety in the same subgroup that is also a more stout plant from what I've seen.

I've removed the Mysore today, and cut the corm up. I'm going to try growing it back, and see if the resulting plantlets are expressing the viral DNA. If not, I'm going to grow them and possibly give them away to anyone who might want them.

BSV can only be transmitted through the vector but the vector could have been around the old mat,so waiting a few weeks after eliminating the old plant is better.
A mat showing BSV symptoms cannot produce a healthy plantlet no matter how much you cut it up,free viral genomes circulate in the plants sap and this are present in the whole mass of the plant. Only through TC with a certain treatment can you obtain healthy plantlets of that variety again but its too much work and since it expressed BSV in the past,the chance of it expressing it again in the future even after curing,is high. It's certainly gonna get stressed again so it will have chances to get reinfected.
