Stefano/Herman...
Very comforting to know that the FMV mite gets killed in our climate. So if we have clean trees, they will probably stay clean, and not be contaminated and weakened by this virus.
As far as I am concerned, UCD, and some wholesalers/retailers are no different than a modern day "Typhoid Mary". I don't care if the cuttings are for "research", or, whatever...they know damn well that their stock is spreading disease. That's irresponsible, period.
I would never grow anything from UCD, or other known contaminated sources. I just cancelled an order from Edible Landscaping. I asked if their stock shows symptoms of FMV. They told me ALL figs are contaminated with FMV. That's bull-s_ _ t! I could care less how rare a variety is. I rather spend my time growing clean, unknowns, from ethnic neighborhoods, rather than waste my growing space on weak, soon-to-be-dying trees. But hey, that's just me.
