Managing Rose Rosette Disease: Beyond Removal

Rose Rosette Disease (RRD), spread by microscopic eriophyid mites, is devastating. Once infected, the only sure cure is complete removal and destruction of the plant. However, mitigation strategies can help protect remaining roses.

Key Facts

• Mites are wind-borne; insecticides like Avid offer limited, temporary control.
• Wild multiflora roses (Rosa multiflora) are primary reservoirs for the virus and mites.
• Remove nearby multiflora roses if possible.

Recommended Actions

• Scout regularly for symptoms: witch's broom, excessive thorns, red pigmentation, distorted growth.
• Immediately remove and bag infected plants—do not compost.
• Disinfect tools between plants.
• Plant resistant varieties where available.
• Consult the latest extension resources: Virginia Tech RRD Guide.

Vigilance and sanitation are your best defenses.
