The International Plant Sentinel Network: a tool for Regional and National Plant Protection Organizations 下载免费PDF全文
Botanic gardens and arboreta are valuable but currently under‐utilized resources in plant health research. Within their vast collections of living plants, gardens play host to expatriate plant species from across the world. These plants offer unique opportunities to study damaging pest and pathogen threats before their introduction into a region where they would be considered invasive aliens. Through these studies, scientists can determine vital information related to these organisms, which can in turn be used to strengthen understanding, contribute to pest risk analysis activities and put in place appropriate quarantine measures or other management programmes. The International Plant Sentinel Network (IPSN) has been working for the last 3 years to provide the support and resources needed for gardens to contribute to such research. The next phase of the IPSN will be to coordinate this research; it will identify, facilitate and provide the already developed tools to contributing gardens. In this way, the IPSN will provide meaningful and valuable information to plant health experts which could help mitigate, or stop altogether, the damaging impacts of new and emerging invasive alien organisms. 相似文献

A survey is given of the history, the tasks and the organization of the Plant Protection Service in the Netherlands. Its activities encompass two major fields, concerning phytosanitary and phytopharmaceutical aspects. In the phytosanitary field, a distinction can be made between long-term and short-term phytosanitary policy, depending on whether one has to deal with existing and established pests or diseases, or with a suddenly arising plant health problem. Two examples are given as illustrations, viz. the approach followed in designing new regulations for controlling potato root eelworm, and the campaign against the recent outbreak of fireblight. A further outline is given on the activities of the Plant Protection Service in the pesticides field, on the responsibilities of the different Ministries concerned, and on the basic elements of pesticides legislation. The restrictions imposed on the use of persistent organochlorine insecticides and organomercury fungicides are summarized. Finally, it is emphasized that the problems of plant protection are becoming increasingly complex as a result of a developing antagonism between phytosanitary and phytopharmaceutical requirements, and of a potential antagonism between these two on the one hand and environmental demands on the other. This situation calls for an integrated approach in plant protection matters, and for an intensified international collaboration. 相似文献
