Great thread.
Mostly conjecture.
Not enough science to back up anecdotal opinions.
Observation, and/or consensus, is not science.
If nothing else....interesting reading.

However, I am inclined to believe trees growing in colder climates are clean, and FMV-free. I have never seen a diseased fig tree in either The Bronx, Westchester, NY...Astoria, Queens...Brooklyn, and surrounding areas. Honestly, until a few years ago, I didn't even know fig trees could get diseased. I learned about FMV from the fig forums and by looking at posted pictures of diseased trees. I look for FMV every time I see a fig tree growing in my area...I see nothing but clean, healthy, growth. IF the trees are diseased, they do a great job at suppressing any visible symptoms.
