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.
