Integrated Pest Management

    The IPM research programme deals with a wide variety of crop protection issues. The basic research aim is to ensure the sustainable control of pests and diseases. Invasive insects and phytosanitary concerns have influenced the research programme significantly during the year. Invasive polyphagous shot hole borer research is seen as a priority. Various research projects are nearing completion including applied research on fruit weevils and the application of biological control agents.
