Invasive Species Biology, Control, and Research. Part 2. Multiflora Rose (Rosa multiflora)

Abstract

Abstract:A 2007 Report to Congress documented a crucial factor in the loss of Army training land: uncontrolled vegetation growth. Of the 53 installations surveyed for the report, 30 reported that approximately 12 percent of their training lands were unusable for certain types of training. Uncontrolled vegetation was a source of such problems as an inability to conduct mounted and dismounted maneuver training, interference with equipment used in line-of-sight training, safety issues, and damage to equipment and structures. Of the 11 plant species (or groups) identified by installations as "uncontrolled vegetation," six were invasive plants, of which the two invasive plants most commonly identified were Kudzu (Pueraria montana) and Multiflora Rose (Rosa multiflora). This work provides a snap-shot of current research and scientific knowledge related to the invasive plant species Multiflora Rose, its impact on the Army, and a concise representation of control technologies for military land managers.

A Survey of Rose rosette virus and Eriophyid Mites Associated with Roses in the Southeastern United States

“…Beds of ornamental roses and wild multiflora roses can serve as reservoirs of both the mite and the virus. Although control of multiflora rose is recommended, it is often difficult due to the numerous seeds produced annually, remote growing location, and regeneration of shoots from roots left in soil (Denight et al, 2008). Beds of landscape roses not frequently inspected for RRD symptomatic plants may serve as reservoirs for mites and virus.…”

“…Shortly after, there were similar reports from Wyoming (in 1941) and California (in 1942) (Thomas and Scott, 1953). RRD has since spread to the south and east of the United States, and it is currently documented from 33 states, including: Alabama, Arkansas, California, Colorado, Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Nebraska, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, West Virginia, Wisconsin, and Wyoming (Amrine, 2002;Bauchan et al, 2019;Denight et al, 2008;Dobhal et al, 2016;. Despite the wide incidence of RRD, the boundaries of the distribution are unknown, notably in the southeastern United States.…”
