Many thanks to the BushDoctor it is Diplodia. I have had samples tested to confirm. I am know wondering which is the best Fungicide product to use during the Spring?

There are quite a few fungicides that you can go to, but I would tend to lean toward a product by Actinovate. It is a granular fungicide that I have used to treat many serious diseases.
If it is severe and persists, then you may have to turn towards copper fungicides, which can be a little more harsh on the soil.
