I'm a few fescue and rye lawns with what appears to be rust. It is bright orange and rubs off on your shoes i can also see a nice "cloud" as the dogs runs through. The lawns I take care of have already had an application of 1-1.5 pounds of slow release N in late February. The diagnosis of rust is proper fertilization and then a fungicide. I assume my fertilizer is good. I would assume my next step is fungicide? Maybe propicinizole since I have it on hand. I'm also attaching a poor cell phone picture. Any more suggestions?
