    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.

Following a discussion of the nomenclature of R. (Corticium) solani, 15 isolates from potato were divided into 3 groups on cultural characters. Growth was not suppressed by the incorporation of oxytetracycline or streptomycin in the media. None of the isolates was very pathogenic; the majority induced light to moderate infection and showed no correlation between type of isolate and pathogenicity.

The fungus was isolated from soil by inserting pieces of jute stem fixed on steel entomological pins for easy recovery. C. solani could be recovered after only 12 h, and was isolated on either cherry agar or water agar. On cherry agar 49 morphologically distinct types were recognized from naturally infected soil. The pathogen withstood severe winter conditions and persisted in soil for at least 9 months. No correlation was observed between degree of pathogenicity in potato and on other hosts.
