    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

Primary foci of phytophthora. could be found in potato fields originating from diseased tubers and on refuse heaps. In De Streek (North Holland) the very susceptible variety Eersteling had I primary focus per 80 ha of potatoes. Infection from refuse heaps was there of minor importance. Only a small proportion of diseased tubers planted gave a primary focus. Spread from the primary foci was studied. Epidemics of phytophthora. under the prevailing weather conditions could be easily explained by spread from the primary foci. 'Field resistance' of the varieties plays a main role in epidemics. A method for testing it in the greenhouse was worked out.

The disease could be controlled not only by spraying but also by careful inspection of seed potatoes and by eradication of primary foci in field and on refuse heaps. Heat treatment of tubers killed the fungus, but would hardly be applicable in practice.
