In September 2004, the administrative session of EPPO Council was followed by a Colloquium on ‘scientific services in support of NPPOs in the EPPO region’ (Madeira, PT, 2004-09-23/24). As a result, a state of emergency was declared and the Council Colloquium agreed on the following declaration: Plant Health Endangered - State of Emergency The work of National Plant Protection Organizations (NPPOs) relies on scientific expertise, but the services providing this expertise increasingly lack staff, funds and training. On the one hand, the whole scientific basis of the phytosanitary field is quickly eroding. Taxonomy, classical plant pathology and other scientific fields which are vital for sustaining sound public policy are threatened with extinction, because they are no longer in the forefront of science priorities. On the other hand, the need for phytosanitary expertise, training and research is substantially and continuously increasing. The number and complexity of plant pest problems increases every year. New developments and new technology have to be mastered, going far beyond existing expertise. Unless urgent action is taken, indispensable expertise and scientific disciplines will irreversibly disappear, and NPPOs will be unable to do their duty.

Inspections in ornamental nurseries and garden centres will be reinforced. As the pest was found at an unfavourable time of the year, the situation will be assessed in spring 2005 at the two locations concerned in order to define phytosanitary measures to be implemented.

L. africanus’) was present. Molecular studies (PCR, cloning and sequencing of the amplified fragments) confirmed the presence of ‘Candidatus Liberobacter asiaticus’ in two affected trees (Citrus sinensis cv. Hamlin and Valencia). It still remains unclear how and when the pathogen entered Brazil.

Inspections were made at premises involved in the production of tomato plants and fruit, as well as on tomato fruit, seed and other material moving in trade. Samples were tested by ELISA. • Premises involved in the production of tomato plants 36 premises were visited (6 were propagators registered for plant passporting and 30 were premises producing or selling tomato plants for retail only). 65 inspections were made and 8 samples were submitted - all were negative. All samples were taken from propagators authorised for plant passporting. • Premises involved in the production of tomato fruit 63 premises were visited, 133 inspections were made and 58 samples were taken, of which 22 were positive from 6 premises (England and Wales). There were 5 outbreaks of PepMV confirmed on nurseries during the reporting period where statutory action was taken. 3 EPPO Reporting Service • Fruit moving in trade 42 premises were visited and 243 inspections were made. 40 samples of imported fruit were tested, of which 36 were positive. The origin of the positive samples was: Spain (mainland: 14; Canary Isles: 19), Netherlands (3). • Seeds 5 premises were visited - 2 were propagators, from whom 25 samples were taken which were all negative, and 2 were growers, from whom 7 samples were taken, with one positive on seed from the Netherlands. The situation of Pepino mosaic potexvirus in United Kingdom can be described as follows: Present, 5 outbreaks were detected in 2003/2004 only in tomatoes grown for fruit production, under official control.

It focused mainly on commercial tomato crops (Lycopersicon esculentum) grown in the field or in protected conditions. Imported plants were also inspected. In 2004, 58 inspections were made on a total of 17,314 plants (corresponding to 131 ha). 4 plants (in 2 samples) were taken and sent to the laboratory for DAS ELISA testing. All samples were negative. The situation of Pepino mosaic potexvirus in Slovakia can be described as follows: Absent, confirmed by survey. Source: NPPO of Slovakia, 2004-11. Additional key words: absence Computer codes: PEPMV0, SK 4 EPPO Reporting Service 2004/148 Pepino mosaic potexvirus does not occur in Sweden A survey on Pepino mosaic potexvirus (PepMV - EPPO Alert List) was done in Sweden from March until October 2004. 24 inspections were carried out at tomato production sites and 18 samples of plants or fruits were tested. All samples were negative. It is recalled that PepMV had been found once in 2001 (see EPPO RS 2001/157), but since then no new infection has been detected. The NPPO of Sweden considers that PepMV is absent from its territory. The status of Pepino mosaic potexvirus in Sweden is declared as follows: Absent, confirmed by survey.

This survey focused on inspection of glasshouses producing tomato fruits. Visual inspections of plants and fruits were carried out in 23 premises. During every inspection, 2-4 samples were taken, even in the absence of any symptoms. One sample consisted of 10 leaves taken from different plants. A total of 70 samples was sent to laboratory and tested by ELISA. All tests were negative. No PepMV has been found in the tomato fruit production of Estonia during the official survey in 2004. The status of Pepino mosaic potexvirus in Estonia is declared as follows: Absent, confirmed by survey. Source: NPPO of Estonia, 2004-11.

It mainly focused on Rhododendron and Viburnum species growing in nurseries and garden centres. It was not conducted in forests, as there are only few wild Viburnum and no wild Rhododendron species in Estonian forests. In addition, all other potential host plants of P. ramorum were more intensively checked during regular inspections. During this survey, 38 inspections were made at 36 premises and 1 arboretum. During each inspection, 1 or several samples were taken and sent for diagnosis, even in the absence of any symptoms of the disease. Out of 48 samples, 35 were taken from Rhododendron, 5 from Viburnum, 3 from Quercus, 2 from Syringa, 1 from Acer and 1 from Fagus.
