How to prevent fungus on roses

[420benz]

I just planted Drift Roses and i have fungus on all of my Knock Out roses.
Should I spray them now with a fungicide to prevent fungus?

Use a 3 in1 product until you become morefamiliar with the nuances of the myriad problems.

Yes, you should use a fungicide. Funginex works for all the major culprits. DO NOT GET IT IN YOUR EYES!!
