2 Multiflora rose (Rosa multiflora)
3 Multiflora rose (Rosa multiflora) Introduced in s Gardens and rootstock 1950s-1960s, US Soil Conservation Service recommended multiflora rose for planting. soil erosion control wildlife conservation Multiflora rose living fence Photo credit: James H. Miller, USDA Forest Service, Bugwood.org

5 Multiflora rose seeds Multiflora rose hips (seeds inside) One large multiflora rose (MFR) may produce 500,000 seeds per year Rapid spread Considered an invasive plant or noxious weed in some states Iowa, Ohio, West Virginia and New Jersey Photo credit: James H. Miller, USDA Forest Service, Bugwood.org
6 The relationship between Multiflora rose and rose rosette disease Multiflora rose is present in much of the central and eastern US Multiflora rose is highly susceptible to rose rosette disease Where we find multiflora rose, we also find rose rosette
7 RRD Distribution Survey for RRD in Red color indicates that symptoms were present in the county.
8 Rose Rosette Disease (RRD) Distribution RRD was first observed 1940s (called Witches Broom of rose) RRD first reported in 1941 in Canada, Wyoming and California. First reported in Midwest in Nebraska in 1968 Photo courtesy James Amrine
9 RRD Distribution Survey for RRD in Red color indicates that symptoms were present in the county.
10 RRD Distribution Both multiflora rose and rose rosette disease can be found in most eastern and midwestern states. It is most common north of I-20.
11 What is rose rosette? Rose rosette disease is A plant virus Researchers in Arkansas recently (published 2011) identified the elusive cause of RRD
12 What is rose rosette? Rose rosette disease is It is specific to Rosa spp. At this point, all cultivated roses are susceptible There are a few native roses that appear to have resistance (very little information about this) For the first time, a diagnostic test for RRV is available
13 RRD Spread How does rose rosette disease spread? Rose rosette is not transmitted mechanically Rose rosette is not transmitted in sap It is transmitted by Grafting Plant Propagation Mite transmission (most effective method)
14 The rose flower and bud mite The microscopic, eriophyid mite Phyllocoptes fructiphilus can transmit rose rosette (first shown in 1968) (eriophyid mite) Phyllocoptes fructiphilus Photocredits: Above-Oklahoma State University; right-usda, ARS.
15 Rise of RRD The Plant Disease and Insect Diagnostic Laboratory (PDIDL) examines samples per year Since 2010, we have received more samples with RRD Landscape rose in Tulsa, OK with symptoms of RRD
16 In recent years, disease resistant roses have been introduced to the market Although these roses are resistant to a number of pathogens, they are not resistant to RRD Most homeowners have at least one rose Rise of RRD
17 Recognizing Rose Rosette Disease Subtle or early symptoms More obvious symptoms
18 RRD symptom: red color to foliage Red KnockOut
19 RRD symptom: red color to foliage Glowing peace rose Many roses have red color to new growth Is this normal? How do I tell?
20 New Growth or RRD? Memorial Day
21 Memorial Day New Growth or RRD?
22 NORMAL
23 Lady Elsie May ABNORMAL - this rose has RRD
24 New Growth or RRD? Queen Elizabeth NORMAL
25 RRD symptom: Excessive thorns (prickles)
26 Electron rose Looks normal
27 Lots of prickles-normal for this variety Electron rose
28 RRD symptom: Excessive prickles (thorns)
29 RRD symptom: Excessive prickles (thorns) Oklahoma
30 RRD symptom: Elongated shoots This symptom will occur with other symptoms such as excessive prickles, red color, etc.
31 RRD symptom: Elongated shoots (or growth only at tip of cane)
32 Usually elongated shoots occur with a rosette or witches broom Lady Elsie May
33 Definition: Witches broom Several branches or stems arise from at or nearly the same point. Usually occurs with shortened internodes.
34 RRD symptom: Rosette or Witches Broom Chuckles
35 RRD symptom: Rosette or Witches Broom
36 RRD symptom: Leaf distortion and discoloration Pink s Promise
37 RRD symptom: Leaf distortion and discoloration Sunsprite
38 RRD symptom: Leaf distortion and discoloration Lady Elsie May
39 RRD symptom: Leaf distortion and discoloration Oklahoma
40 RRD symptom: Flowers are distorted, reduced or blighted Brass Band
41 RRD symptom: Flowers are distorted, Cherry Parfait reduced or blighted
42 RRD symptom: Flowers are distorted, reduced or blighted Chrysler Imperial
43 RRD Symptom: Dieback (rule out fungal cankers) Chuckles
44 RRD symptom: Dieback Carefree Spirit
45 RRD symptom: pliable or fragile stems Marie Daly
46 RRD symptom: Stunting and reduced vigor Charisma
47 Carefree Spirit RRD symptom: Stunting and reduced vigor
48 RRD symptom: Overall Decline Oklahoma
49 What to do when RRD is suspected? If there are obvious RRD symptoms, there is no need to submit a sample If a testing is needed, collect symptomatic shoots Wrap in newspaper or a few dry paper towels Immediately put in a sealed plastic bag Store in the refrigerator until it is delivered to the local county extension office
50 What to do when RRD is suspected? A specialist will examine the sample for the microscopic rose mites Be sure to collect several shoots (even if some are healthy). We are less likely to find mites on small samples. The rose mite, Phyllocoptes fructiphilus at the base of a rose bud.
51 Investigate the use of chemicals in the area Especially herbicides Lawns Driveways Spot sprays Sprays made by your neighbor (or your spouse)
52 Herbicide damage (in this case glyphosate) looks similar to RRD
53 Investigate the use of chemicals in the area Herbicide applications may have been made the previous season or during dormancy When in doubt, send a sample for laboratory testing
54 Herbicide damage (in this case glyphosate) looks similar to RRD
55 Questions? About rose rosette virus or symptoms? (more info about the mite and management will be delivered in the next presentations)
