That's right, there are no pear trees that are absolutely immune, but there are a few varieties that are very resistant to getting it, and many varieties that are more resistant than others.

There are also several strategies you can undertake to minimize the possibility of your tree getting it, and seasonal climate has a big part to play.

'Magness' is an excellent variety that has been grown in West Virginia (unfortunately 'Magness' is a terrible pollinator towards other pear trees, so that may be something to consider). 'Orient' and 'Kieffer' are two others that are regarded as the most fireblight resistant.

A little off-topic, but if anyone was curious which variety is the one that is MOST susceptible, it's the one I have, haha. The French variety Passé Crassane. Fortunately it's in a dry climate where fungal disease is rarely ever a problem.

If you're interested in Asian pears, I believe Shinko is considered the most fire blight resistant.

Thanks for all the comments. I live in the hot,,very wet at times southern Iowa. Do not see many pear trees down here,,guess that I why! have to stick with apples

One of the newer fireblight-resistant varieties is Sunrise. I bought one last year, so I can't comment on it too much. I think it's kind of hard to find. Stark carried it last year but not this year. Adams County has it, but they're always sold out of everything.

shinko has been fireblight resistant for me and one of the best tasting asians I have grown. I live on the northern coast of florida in zone 8b
