Any ideas anyone on what I need to do? Thanks.

Hi Capone

I suspect that you have Fire blight which is spread by Bees. Go to
your Horticultural Wholesaler and get some "Agricultural Streptomycin"
Fire Blight is a bacterial disease.

Apply by spraying your Rowan tree (Sorbus).

You're posting from the US, are you not? Is this advice equally
applicable to the UK? I've never seen a rowan suffering from fireblight.

Googling shows rowans in the UK do get fireblight. Treatment suggested
for the amateur is pruning and disposing of affected branches or getting
rid pf the whole tree.
