Yeeeeeeep.
The good news is that it likely won't die, and if it does live you will eventually get some good tasting pears in years without FB.
The bad news is that every year FB is a problem it will look like Hogan's Goat and all those snobby neighbors in that subdivision will turn their nose up at you.
If you plant another summer pear, make it an Ayers. All those neighbors will be happy then and you will too.
