    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.

The first part of this paper deals with investigations at the Phytopathological Laboratory, Wageningen, into the control of Alternaria spp. (mainly A . raphani) on radish seed by chemicals. Organic mercury compounds proved better than thiram products and were more effective wet than as dusts, ceresan and germisan wet treatments being the best (99 % control) and, as 1 % for 4 to 8 min., not phytotoxic.

The fungus was able to penetrate to the interior of the seed and may thus prevent germination. The fungicidal effect of ceresan increased when seed was stored up to 32 days after treatment, but the phytotoxic effects were also greater.

Of the antibiotics tested, some had no effect, and actidione, though giving control, proved too phytotoxic. Rimocidin at 200, 400 or 800 p.p.m. for 16, 8, and 4 h respectively, was more effective; at 400 p.p.m. for 30 h it eliminated deep-seated infection without injury to the seed and in this was superior to ceresan.

The second part deals with the relative value of thiram and mercurials as seed protectants against unspecified soil fungi. In cold tests with maize seed (germination in unsterilized field soil at low temperature) arasan SF-X at 0.2 to 0.3 % was the most effective of the thiram products and was less phytotoxic and more persistent than ceresan-new.
