porkpal,
Well it seems we all forgot our manners and none of us even welcomed rmbryant38
I guess black spot is an important issue to us all and we got carried away. The original question was "What is the best spray for black spot".
dyzzypyxxy, gave some suggestions and I stated that I had not much luck with sprays. It is a hard question to answer, I guess in some areas black spot is worse than others and I suppose the selection of roses would influence that also. In his/her area the organic methods might do just fine and they may have no need for chemical controls. I have used Daconil and Immunox but with less than satisfactory results.
