I live in one of the biggest dairy counties in PA, so when dairy farmers say "Jump" the establishment usually says "how high?" I remember reading about this in a local paper when it happened; I don't know who decided this for our county/township. I do know that this was NOT done in nearby Fulton County (which has a glorious bloom of R. multiflora in June that smells like driving through heaven); Fulton is more mountainous and not as "dairy" as we are.
Look up what Rose rosette looks like in affected roses and if you see anything like it, spray to kill mites and try inserting zinc galvanized wire or nails into the rose just above the roots. It has to be zinc.
