    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.

Some insecticides were tested in systematic trials or on a small scale, especially for ovicidal action, residual activity in relation to life cycle of red spider mite (Tetranychidae), herbicidal activity and method of application. Practical experience with them was gained with flowers under glass.

Azobenzene was a good acaricide and was also herbicidal but could in practice only be used on carnations. Parathion was satisfactory, except as a powder, if used repeatedly; resistance to it arose once just before the trial ended. Sodium selenate, a systemic insecticide, was efficacious for carnations; excess stunted growth. The selenate spray damaged roses. Soil treatment was satisfactory only in high doses. Pestox (bis(bisdimethylaminophosphonous anhydride)) had some effect on carnations and hortensias, and was transmitted through carnation plants. In practice an old remedy, spintspuit (mite spray), was effective but was laborious and raised risks from fungi. TEP (a tetraethyldiphosphate) was also tested.
