[NAFEX] Bradford pear seedlings as invasive species

'Bradford' and perhaps other callery seedlings of Bradford may not be a "problem" much longer.  I started seeing severe fireblight in a row of Bradfords near the RDU airport a few years ago and this year I've seen more blight-stricken Bradfords in neighborhoods.  It would not surprise me to learn that E. amylovora had mutated to form a new strain that infects formerly resistant callerys.

I hope that I am mistaken and these infected trees are actually seedlings of a susceptible callery strain that were mislabelled (but I doubt it considering the dominance of Bradford in the nursery trade).

When this subject came up briefly a year or so ago I cut down the 15
pears growing in my pastures.  They were very thorny, lot of flowers,
virtually no fruit that I could discern, up to 6 inches in trunk diameter.
I see several along other farm fields in the Spring.
