Specific scope

This Standard describes the procedure for inspection of places of production of Fragaria plants for planting. The Standard includes relevant sampling procedures. The Standard focuses on pests of concern for the EPPO region which are present in the EPPO region. The purposes of a place of production inspection may be for export or for internal ‘within country’ use. Alternatively, inspection may be carried out as part of a national survey for monitoring or to determine country or area freedom for specified pests. The Standard also provides guidance which may be relevant to exports to non‐EPPO countries, in which case the pest lists and requirements for the importing country should be consulted. A procedure for inspecting imported plants from outside the EPPO region is covered in EPPO Standard PM 3/73 Consignment inspection of Fragaria plants for planting (EPPO, 2008).

Specific approval

This Standard was first approved in 2017‐09.  相似文献

Candidatus Liberibacter solanacearum’ was recently described as the causal agent of potato zebra chip disease. This pathogen occurs in North America, New Zealand, and Northern Europe on various crops, and may spread to other potato growing regions. Observation on ‘Ca. L. solanacearum’‐infected tomato and potato plants propagated in growth chambers over 5 years indicated that tomato plants (cvs Moneymaker and Roma) can be a latent carrier of ‘Ca. L. solanacearum’. Tomato plants graft‐inoculated with scions from latently infected tomato plants remained symptomless, but tested positive in a species specific PCR assay. ‘Ca. L. solanacearum’ was consistently detected in the top, middle and bottom portion of the symptomless tomato plants, including stem, petiole, midrib, vein, flowers and fruits. In tomato fruits, ‘Ca. L. solanacearum’ was evenly distributed in the tissues at the peduncle and style ends, as well as in the pericarp, and columella placenta tissues. This is the first report that ‘Ca. L. solanacearum’ is present in a plant reproductive organ. In contrast, potato plants (cvs. Jemseg, Atlantic, Shepody, Frontier Russet, Russet Burbank, Red Pontiac, and Russet Norkotah) grafted with scions from the same latently infected tomato plants resulted in typical symptoms of purple top, leaf scorch, and other disease symptoms in plants and brown discoloration in the vascular ring and medullary rays in tubers.  相似文献

Specific scope

The purpose of the EPPO Standard on Castanea is to recommend to EPPO Member Governments the phytosanitary measures which they should use or require for Castanea plants and plant products moving in international trade to prevent the introduction and spread of quarantine pests. Some of these recommendations are addressed to all EPPO Member Governments, others are addressed only to countries considered to face a certain level of risk from the introduction and spread of the regulated pests concerned. All these recommendations were derived from:
  • EPPO Standards PM 1/2 (EPPO A1 and A2 Lists) and the former EPPO Standards PM 2 (pest‐specific phytosanitary measures), or
  • Pest Risk Analysis (PRA) carried out or reviewed by EPPO, or
  • the Working Party on Phytosanitary Regulations.
For wood packaging material, recommendations are based on ISPM 15 Regulation of wood packaging material in international trade.

Candidatus Liberibacter solanacearum’ is a phloem-limited Gram-negative bacterium that causes serious damage to different crops of the botanical families Solanaceae and Apiaceae. Five haplotypes have been described: LsoA and LsoB are present in solanaceous crops in America and vectored by the tomato/potato psyllid Bactericera cockerelli; LsoC affects carrots from Northern and Central Europe, and is transmitted by the carrot psyllid Trioza apicalis; haplotypes LsoD and LsoE are present in Southern Europe and Morocco in carrot and celery, and are associated with the psyllid Bactericera trigonica. Thirty-four ‘Ca. L. solanacearum’ isolates were collected in six different regions of Spain from distinct Apiaceae hosts (carrot, celery, parsley and parsnip) in eight consecutive years and were analysed. Their haplotypes were determined by a sequence analysis of 16S ribosomal RNA, the 16S–26S ribosomal RNA intergenic spacer, and the 23S ribosomal RNA and rplJ and rplL genes. Both haplotypes LsoD and LsoE were found across Spain, and no host specificity appeared between these two haplotypes. This is the first report of ‘Ca. L. solanacearum’ associated with parsley and parsnip.  相似文献

Specific scope

This Standard describes a diagnostic protocol for Ditylenchus destructor and Ditylenchus dipsaci. 1 This Standard should be used in conjunction with PM 7/76 Use of EPPO diagnostic protocols. Terms used are those in the EPPO Pictorial Glossary of Morphological Terms in Nematology. 2

Specific approval and amendment

Approved in 2008‐09. This revision was prepared on the basis of the IPPC Diagnostic Protocol adopted in 2015 on D. dipsaci and D. destructor (Annex 8 to ISPM 27 Diagnostic protocols for regulated pests). The EPPO Diagnostic Protocol is consistent with the text of the IPPC Standard for morphological identification for this species. For comparison with other species the IPPC table includes Ditylenchus africanus whereas the EPPO table includes Ditylenchus convallariae due to the different distribution of the species. The molecular tests for which there is experience in the EPPO region are described in full in the appendices (some of these are additional tests to those in the IPPC protocol). Reference is given to the IPPC protocol for tests for which there is little experience in the EPPO region. DNA barcoding is also included. Revision approved in 2017‐04.  相似文献

Zebra chip, an emerging disease of potatoes, has recently been associated with ‘Candidatus Liberibacter solanacearum’ in New Zealand. The phloem-limited bacterium is known to be vectored by the tomato potato psyllid (Bactericera cockerelli). In this study, the role of tuber transmission in the spread of Ca. L. solanacearum was investigated by re-planting potato tubers infected with Ca. L. solanacearum in the absence of the psyllid. Nested PCR demonstrated that Ca. L. solanacearum could be transmitted from the mother tubers both to the foliage of growing plants and to progeny tubers, resulting in symptomatic and asymptomatic plants. Of 62 Ca. L. solanacearum-infected tubers four did not sprout symptomatic of zebra chip. A further two plants developed foliar symptoms associated with zebra chip during the growing season and died prematurely. Fifty-six of the infected tubers produced asymptomatic plants, although Ca. L. solanacearum was detected in the foliage of 39 of them indicative of transmission into asymptomatic progeny plants. At harvest, Ca. L. solanacearum was found in the daughter tubers of only five of the 39 asymptomatic plants, and only one of these plants was found to have zebra chip symptoms in the daughter tubers. Our results show that tuber transmission of Ca. L. solanacearum could play a role in the life cycle of this pathogen, providing a source for acquisition by Bactericera cockerelli and for movement of the pathogen to other regions of New Zealand via transport of seed tubers.  相似文献

This Standard describes a diagnostic protocol for Xiphinema americanum sensu lato 1 . This Standard should be used in conjunction with PM 7/76 Use of EPPO diagnostic protocols. Terms used are those in the EPPO Pictorial Glossary of Morphological Terms in Nematology 2 .

Specific approval and amendment

Approved in 2009‐09. Revised in 2017‐01. This revision was prepared on the basis of the IPPC Diagnostic Protocol adopted in 2016 (Annex 11 to ISPM 27, IPPC, 2016). This EPPO Diagnostic Standard differs in terms of format but it is consistent with the content of the IPPC Standard. However, since the adoption of the IPPC Protocol 5 new species have been added into the group and are included in this version of the EPPO Protocol.  相似文献
