Phytosanitary requirements for the domestic movement  
of Prunus  spp. plant material  to prevent the spread of 
plum pox virus (PPV) within Canada   
 
Effective date: Month DD, 2022  
(Original)  
 
Subject  
 
This directive describes the domestic movement requirements for  all Prunus spp. plant material 
as it relates to plum pox virus (PPV) within Canada.  In addition, this directive outlines the 
restrictions on the sale and propagation of regulated Prunus species plant material  within 
established quarantine areas in Canada and describes the CFIA inspection and monitoring 
activities conducted to enforce these re quirements .  
 
The domestic requiremen ts within this directive supersede all domestic requirements found 
within D-99-07: Policy for Importation from the United Sta tes and Domestic Movement of Plum 
Pox Virus (PPV) susceptible Prunus  Propagative Plant Material  and all  previous versions of 
directive D -99-07.   
 
The following changes to the domestic policy requirements are reflected within this directive:  
 
 The r emov al of domestic restrictions on seed  of susceptible host species, as the current 
scientific information  on virus transmission  no longer supports regulation of this 
pathway.   
 Section 5  has been updated  to change the minimum record retention period  from one 
year to two years  for facilities participating in formal agreements to move dormant 
nursery stock and greenhouse -grown seedlings out of the PPV quarantine area .   
 Section 5  has been updated to clarify requirements that facilities must meet for CFIA to 
permit the movement of  dormant nursery stock  and greenhouse -grown seedlings  from 
the quarantine area .  
 The lists of PPV -D susceptible and PPV -D non -susceptible species found in Annex 2 and 
Annex 3  have been updated to follow  Prunus  subdivisions presented in the USDA’s 
Germplasm Resources In formation Network (GRIN) Taxonomy  (USDA -ARS 2022) .  
 Minor administrative changes to improve the format and clarity of the text.

For the purposes of this directive, “propagation” refers to the act of grafting, budding, rooting, 
planting, or any other related process w hich results in the multiplication  of, or increase in the 
number of individual plants, or the introduction of new germplasm to an existing plant.   
 
3.0 Introduction  
 
Plum pox virus (PPV) is a virus that affects both  ornamental and  fruit -producing  Prunus  speci es. 
Symptoms of the virus may include chlorotic ring spots on leaves and fruit, decrease in fruit 
yield, and early fruit drop.  
 
The two main pathways through  which  PPV is spread are aphid feeding and propagation  
activities using  infected material.  Once a tree has become infected,  the only way to destroy the 
virus  and prevent its spread is to remove  and destroy  the infected  tree and its roots.  
 
PPV was first detected in Canada in 2000, in stone fruit production  areas  in Ontario and Nova 
Scotia. Following eradication activities between 2000 to 2011, the only remaining PPV 
quarantine area is in southern Ontario, as outlined in the List of Plum Pox Virus (PPV) 
quarantine areas in Canada  in Annex 1 .  
 
Prohibiting propagation o f Prunus  spp. host material within the quarantine area help s to limit 
the spread of PPV within this zone , while restrictions on the domestic movement of host 
material mitigate the risk of  introducing  PPV into  non-infested  areas within Canada.  
 Month, day, 2022                                                D-22-02 (Original)  
 
 
  Page 4 of 11 The genus Prunus  falls within the family Rosaceae and can be further divided into subgenera, 
which are  smaller, more closely related groups which share common characteristics. There are 
also several strains of  PPV that infect  different  Prunus  species  falling within these subgenera . 
The s train that has been detected in Can ada and the United States  is the Dideron  strain  (PPV-
D), which is known to  naturally infect three subgenera of the genus Prunus : Amygdalus , 
Emplectocladus , and Prunus .  The Dideron st rain is not know n to naturally infect  species within 
the subgenera Cerasus .  The s pecies listed in Annex 2  are naturally susceptible to PPV -D and are 
therefore considered regulated  species  which  are subject to the requirements  outlined within  
this directive , whereas the non-susceptible species  listed in Annex 3  are exempt . Note that 
isolated detections of  the Winona strain ( PPV-W) and the recombinant strain ( PPV-Rec) have 
also been found in Canada; h owever, the infected trees were subsequently removed and 
destroyed and the surrounding area s have been intensively surveyed with no further 
detections.  PPV-D is the only strain that remains present in North America (Hajizadeh et al. 
2019).

Note:   This directive describes only the phytosanitary requirements related to PPV. Please 
consult the list of Plant Health directives  for additional  requirements  which may apply .  
 
6.0 Specific requirements  within PPV q uarantine areas 
 
6.1  Propagation  of regulated articles   
 
Propagation of all regulated Prunus  species (as listed in Annex 2 ) located within an established 
PPV quarantine area  is prohibited.  Prohibiting propagation within an established quarantine 
area assists in controlling the spread of PPV by  restricting the use of potentially infected plant 
material as a propagation source in order to limit the further spread of the virus through this 
pathway.   
 
The CFIA may permit propagation of regulated articles f or research purposes, provided the 
facility demonstrates that they can meet all necessary requirements  and approval  is granted by 
CFIA in writing prior to any propagation activities.  Contact your local CFIA office  for more 
information.  
 
6.2 Sale  of regulated articles  
 
Plant material of r egulated Prunus  species , such as trees and shrubs, that are not propagated in 
the quarantine area may be sold within the quarantine area, provided that  the following 
conditions are met : 
 A Notice of Prohibition or Restriction of an Activity  specifying the required conditions 
must be issued to the  vendor  by the CFIA prior to any sales. 
 All sales  of regul ated material  must be made  to customers  verified to be  residing within 
the quarantine area.  Month, day, 2022                                                D-22-02 (Original)  
 
 
  Page 8 of 11  Detailed  sales  records, including  the quantity  and species of the  regulated  material, 
and the  location (address and city)  to which the  regulated  material was distri buted , 
must be  kept for two  year s and made ava ilable to the CFIA upon request.  
 
6.3 CFIA Inspection Procedures  
 
The CFIA conduct s routine inspections of properties located within PPV quarantine areas to 
verify  compliance with the requirements outlined within this directive . Inspections will be 
based on risk and compliance history of spec ific locations, and may include both residential and 
commercial properties. These p roperties may be inspected for propagation activities such as 
grafting, budding , or growing t rees from seed.  
 
Retail, wholesale, and landscape companies operating within a PPV quarantine area may also 
be inspected to verify compliance under domestic movement requirements and conditions for 
the sale of regulated material within the quarantine area.  Verification may include inspection of 
material present on site and review of sales records and inventories.  
 
Any non -compliances identified during the inspection process will be dealt with as outlined in 
Section 7 . 
 
6.4       CFIA Monitoring Procedures  
 
The CFIA conducts annual monitoring activities to assess  the PPV quarantine area  and maintain 
Pest Free Areas  through collection  of samples of select  PPV-susceptible species to determine 
the presence of  PPV. As per the guidelines listed in the North American Plant Protection 
Organization’s Regional Standard for Phytosanitary Measures (RSPM) 18 : Guidelines for 
Phytosanitar y Actions F ollowing  Detection of Plum Pox Virus , the sample risk categories include, 
but are not limited to, the following:  
 Commercial orchards along the periphery of the quarantine area;  
 Commercial orchards up to 10  km outside of the quarantine area;  
 Residential locations along the periphery of the quarantine area; and  
 Residential locations up to 1.5  km outside of the quarantine area.  
 
7.0 Non -compliance  
 
Any non -compliant p roducts that are moved out of the quarantine area are to be returned  to 
the quarantine area or destroyed  in a manner approved by the  CFIA . The person in possession, 
care or control of the shipment is responsible for any and all costs relating to the movement  
and/or disposal  of the non -compliant material , including  fees for CFIA oversight of  these 
activities.
