I know this is hard to believe but all roses are equally susceptible to rrd. If an infected mite lands on a bush it will come down with rrd. Eriophyid mites are very slow crawlers so they tend to stay where they land. They feed on the inside of the bud or stems until their ready to leave the shrub. By quickly removing the rose you can prevent the spread. It has been found that the mites tend to leave their host plants at two times. When plants become stressed due to drought and during rain events.
