Questions
Did you assume the TMV came from having a butt while planting or did you
have it tested by VA Tech?
TMV can be seed borne, Did you do chlorine treatment before planting?
Can be in crop debris, then insect vectored. Any pile of debris around? Esp
since you are in tobacco country.
Any neighbors growing tobacco with this disease?
Can be in other host plants like Datura, horsenettle + 148 others. and then
insect vectored. Did you check for infected weeds?
Being vectored by smokers was published in 1896 (over 100 years ago) when
80% of the worlds crop was infected and smokers rolled their own.
I know some folks that have farms with 3 generations of smokers that never
saw TMV.
Smoking here and handling plants for over 50 years never had TMV.
Too many variables to blame on just 1 butt.
TMV is in the same catagory as botulism as far as numbers. BUT can be
controled with dishsoap. 1 tbsp per gal of water, applied weekly. Ergo TMV
is a micro problem disease.

1998 stats TMV in cig tobacco 0.137%, world crop.
