But in that same area, the Ledbetter pear produced for me. I planted a seckel tree in southern part of our city which is the fireblight capital, and the seckel lasted only a couple of years, the fireblight simply burned it out. It blooms slightly off time with Bartlett and is able to avoid the disease most years, that's why the incidence of fireblight is low and have been mistaken to be fireblight resistant. Seckel is not a true fireblight resistant pear, it isn't tolerant either. The Kieffer pear is not really fireblight resistant but fireblight tolerant, it could get hit, but one thing excellent about this pear is that even if it gets hit, it can remain vigorous, and still be productive. The Ledbetter pear is proven to be fireblight resistant. Not to mention that there could also be other strains or mutations of fireblight bacteria in different localities, and so cultivar resistances could vary. The ratings posted are most likely accurate but they are not the true measure of fireblight resistance, so you have to understand that the even the most fireblight tolerant pears could get hit if the timing is right. ![]() ![]() Thus in one area, some cultivars are scored as "resistant", but the same cultivar could be very susceptible in another area. ![]() Most resistance or tolerance are based on scoring through the years but are most probably due to avoidance because they bloom outside the time when the incidence for infections are high. If you place the fireblight bacteria on the fruit or on the bruises of most pears, they will get fireblight. There are very few true fireblight resistant pears.
