Here are the pear varieties worth look at if you want to avoid fireblight :
17 Fireblight-Resistant Pear Varieties
Asiatic pearsare more susceptible to the disease thanEuropean cultivars , so you ’ll mostly see the latter on this list .

Somepears expect a pollinator to grow fruits . Unless we call out otherwise,‘Bartlett’is always a good pollinator for all the entries in this list .
It ’s also the pear motley that growers equate others to in footing of when the yield ripens .
