The strategy of a comprehensive approach using a wide range of methods is gradually being recognized as a much more effective form of plant protection than traditional practices, and this approach offers very good prospects. We are beginning to understand that plant protection is not a simple matter of intensification, but can be a stabilizing factor for harvests with harvest size determined by a complex of ecological and related circumstances.

. Similar ecological studies have been conducted in the CSAV Research Institute of Plant Protection at Praha-RuzynS and in the Plant Protection Departments of the Faculties of Agriculture in Prague, Ceske Budejovice, Brno, and Nitra.

Such studies are conducted in the SAY Center for Biological and Ecological Sciences and in the Research Institute of Plant Protection at PrahaRuzynS. Methods of meristematic tissue and embryonic cultivation developed in the CSAV Institute of Experimental Botany and in government research institutes enable us to obtain healthy, virusfree seedlings, and are already used for biological protection of plants against viral diseases (Novak 1987)

Methods of mass rearing, distribution, and application of three species of predators and parasitoids were developed at the Agronomy Faculty of the Agricultural University at Ceske Budejovice, at the CSAV Institute of Entomology, and at the SAV Center for Biological and Ecological Sciences. Moreover, two biopreparations based on Pseudomonas putida 11 and Agrobacterium radiobacter for bacterization of sugar beet and wheat seeds to prevent root diseases were developed in the CSAV Microbiological Institute and the Research Institute of Plant Production at Praha-Ruzynfi.

The following approaches are particularly important for reducing chemical use in agriculture and for obtaining the foundation for promoting the natural development of parasites and predators: • Development of genetic methods which would enable us to keep pests under respective economic thresholds by introducing lethal genes into their populations;

New results of scientific research will be applied as widely as possible, including results from molecular biology, biotechnology, mathematical modelling, and genetics. There are various promising lines of action which should be given support, such as: • Searching for new microbiological preparations for application in plant protection; selection of active strains and strains with specific effects; searching for microorganisms which produce biologically active substances (metabolites)

• Improvement of our knowledge of the effects of pesticides on nontarget organisms and whole biocenoses. We should lend support to the work of SGOMSEC on "Methods for Assessing Adverse Effects of Pesticides on Non-Target Organisms." A workshop on this subject will be held at Ceske Budejovice in 1988, and a volume with this title will be published in the SCOPE series.
