This rose is totally appalling for blackspot. I grow it as a climber supported on wires that way it has a better air movement and hopefully a little less of this disease as it chases the new healthy leaves up the stem. Other roses near by that wouldn't necessarily have gotten it have the disease especially on their leaves closest to this rose. I am going to move it further away into the wilder parts of the garden. Here its only neighbour will be 'poylantha 'Grandiflora'. However, despite being such a leper it has made some really good growth with shoots reaching almost 4M high. The flowers are so incredible it is worth any amount of ugly unhealthiness.
