Gang:

Well I now have it on excellent accord that it is indeed fireblight.  

And as one of you suspected the tree in question is Magness.  That is 
why I have been so hestitant about the whole thing.   And this is not 
the first time.  I have had my Magness trees heavily infected by Fire 
Blight over the past 5 years.   

Naturally the first time this happened I though I simply did not have 
a tree that was true to name (even though I grafted it myself).  So I 
ordered scion wood from Corvallis and Bear Creek.   Same result.   
Fireblight got each of them.   I have set these out on OHxF 513, OHxF 
282, OHxF 333, and one of the new dwarfing pear rootstocks.  

What makes it more interesting is Warren sits right next to them and 
it has never been infected (ahh I see some eyes roll).  In fact I am 
growing Bosc, Bartlett, Harest Queen, Harrow Sweet, Harrow Delicious, 
Rescue, Chapin, Potomac, Seckle, Comice and a bunch of others.    I 
also have a few apples around, the only thing that has  fire blight is 
Magness.   It baffles the mind.

 I suspect, as do many that fireblight runs in strains.   I guess we 
just have a picky one here.  I count my blessings that I had the 
desire to "test" before I set out a real production orchard.  If I 
listened to the extension agent I would be growing Magness in mass, 
and if I relied on literature rather then experience I would be one 
unhappy bunny at this point.

The moral is test, retest, and test again varieties in your local 
area.

The fluffy one
