Rose Rosette Disease: An Update - Sunday March 25, 2018, at 2:00 pm at the US National Arboretum Auditorium
We have all seen the unsightly stands of Knockout Roses planted in median strips and occasionally, our home gardens, that have strange, deformed stem and leaf configurations. This anomaly, known as Rose Rosette Disease, attacks our hybrid teas, climbers, shrubs and all other types of roses. Join The Potomac Rose Society at the US National Arboretum to hear Dr. Mark Windham, a leading researcher on Rose Rosette, and get the most recent update on this disease that is a threat to the gardens of all rose lovers, along with Recommended Rose Varieties for Disease Resistance.
DR. MARK WINDHAM will discuss current research being conducted on Rose Rosette Disease (RRD), as well as the latest research identifying disease resistant varieties. The American Rose Society Research Endowment Trust identifies Rose Rosette Disease as the greatest threat to the future of commercial and recreational growth, and the enjoyment of roses. In 2012, ARS selected Dr. Windham to head a three-year study about the management of RRD. The objectives were to determine how rosarians manage RRD in their gardens and identify best practices
for RRD, besides eliminating plants with symptoms. Dr. Windham also believes that roses have lost popularity due to growing public aversion to the regular use of pesticides in home gardens and has therefore been developing a list of roses that homeowners can successfully grow without reliance on chemical control tactics. Rose Rosette will continue to be a threat to our home gardens for years to come. In a grant fully funded by the USDA National Institute of Food and Agriculture’s Specialty Crop Research Initiative, Dr. Windham is included in a group of 18 scientists concerned with Rose Rosette research (housed at Texas A & M), that continues to lead research on Rose Rosette Disease.
The National Arboretum is located at on 412 acres at 3501 New York Ave NE, Washington, DC 20002.
Join the Potomac Rose Society for free entry into this event. Membership is $15. Join us for refreshments and conversation after the program.
