Rosette or RRD has no cure. Remove the affected rose/roses and garbage them. Make sure to sanitize the shovel etc.

For black spot

2 methods

1 tsp neem oil + 2 tsp dish or Castile soap + 1 gallon water. Remove the folliage with black spots and Spray the plant generously after sundown.

Method 2

Milk milk and water 1:2 ratio and spray after sundown.

I am currently doing this for my Neil diamond rose bush.

Both treatments can be alternated weekly until the black spot is gone. Reapply one of the methods after rain.
