Doc. I don't have a link for you......I can say this.....I (and several others in our little collective) Have over the years sent to MSU a total 172 samples to be tested by their Ag lab.....NONE have been tested as positive for TMV or Bean strain or the legendary "Sunn-Hemp rosette" that is listed in Wiki.
It was explained to me that it is able to be transmitted by direct contact only. The possibility factor for that here is beyond low due to no industrial hemp having been grown in the US for years.....The Agronomy labs at MSU have not seen a positive test in decades......One professor thinks it may have mutated OUT of compatibility to "our" strains by the constant breeding of new strains for our use as compared to Industrial. (I don't know about that myself)
I (we) stopped sending samples a cpl of years back....
The most given report was broad mites......btw.
So then, for any of "your" plants to get MV. The plant must touch an infected plant OR the grower must tough one and transfer it to his grow.....
Still believe it's around? Want to not get it? Don't touch anybody's plants but your own!!!! Not hard to do....
