The 13th triennial meeting of the Virology Section of the European Association for Potato Research (EAPR), hosted by the Scottish Agricultural Science Agency (SASA) and the Scottish Crop Research Institute (SCRI) was held at the Hilton Hotel, Coylumbridge, Aviemore, set in a woodland estate in the centre of the Cairngorm National Park, the largest national(More)
The occurrence of ‘Candidatus Liberibacter solanacearum’ (Lso) was determined in commercial and wild species of the family Apiaceae, obtained from three seed collections held in the United Kingdom. The accessions dated from the 1970s and the seed had been sourced worldwide. Although only small quantities of each seed accession was tested, a high proportion(More)
Viroids can cause diseases of considerable economic importance; in Europe the main concern is with pospiviroids that may affect the tomato and potato industries. Methods for detection are required that are both sensitive and robust. The detection method described here is a probe hybridization method with a commercially available digoxigenin (DIG) labelled(More)
Potato tubers (Solanum tuberosum L. cv. Monalisa) showing superficial necrotic rings typical of Potato virus Y NTN (PVYNTN) infection were collected from commercial potato fields in the State of São Paulo (Brazil). An isolate named IAC-PVYNTN was characterized by sequencing 822 and 836 nucleotides from the coat protein and P1 protein coding genes,(More)
Phytoplasma infections are regularly reported worldwide, and concerns about their threats on agricultural production, especially in relation to global climate change, are increasing. Sensitive and reliable detection methods are important to ensure that propagation material is free of phytoplasma infection and for epidemiological studies that may provide(More)
Assumptions are identified and made in an attempt to model the acute human health risk associated with a hypothetical fire in an insecticide storage facility. The insecticides used in the model are endrin and dimethoate. The model indicates that persons residing a few hundred meters from the facility could suffer a variety of adverse effects, including(More)
