Cartoonishly bad fire blight

So I was doing my pruning and spraying and I noticed this on my pear tree, which if this isn’t fire blight then I don’t know what is…

Except, I don’t know what is, so I need help :joy::rofl:.

I hit it with a judicious spraying of Kocide 3000, but what else should I do for this tree? Obviously removing the infected area isn’t going to work!

Thanks!
