Pest on Pyracantha

Is this Fireblght? If so it can spread, There seems to be no specific chemical for this but applications of copper fungicide for control of apple canker may help?. Affected parts need to be removed and burned. I think I would remove the whole plant.

It looks like a pyracantha so fire blight is a strong possibility but, is that a birds nest? I would have thought fire blight would have killed all the leaves. From the picture it could be aphid combined with the black fallout from it. I have to say I can't really tell but if you have doubts remove the worst parts and see what happens. If it progresses then Drc726 is probably right about taking it out. I was talking to a friend last week and she said that in the space of two weeks fire blight had killed her pyracantha, so it appears to be quite fast.

Thank you for your comments - really helpful.There are still plenty of glossy leaves on my Pyracantha and yes,Cutsandgraz, you did spot an empty nest. This pest has been on the shrub for at least a month so highly likely that it's not Fire Blight. I will attend to it as suggested. Fingers crossed!

Fireblight doesn't leave fuzzy patches like that, though. It looks horribly like the wooly aphid that I have dealt with, though. If you can get even closer, so we can see the shape of the bugs, that would be conclusive.
