Integrated crop protection (IPM) in Nordic and Baltic berry crops

Jan. 30 - 31, 2017 in Riga, Latvia

Berry crops are high value minor crops in the North-European zone. They require a special attention in growing and protection because of small plantations. Sharing knowledge of these topics and finding common solutions is a very important factor for this sector of agriculture in North-European zone. The seminar aims to be a meeting place for scientists, advisors, students and others interests in the current and future plant protection practices and challenges in North-European berry crops. The seminar language is English. Seminar fee includes lunches, refreshments and conference dinner.

This is the fifth seminar organized by working group "Plant protection in Sustainable Berry Production" in NJF section “Plants”.

Keynote speakers:

Jørgen Eilenberg (University of Copenhagen)- "Microbiological control in strawberries: results from IMBICONT bilateral collaboration between Brazil and Denmark." 

Stuart MacFarlane (James Hutton Institute)- "Soft fruit viruses spread by mites and insects."

Sanja Manduric (Swedish Board of Agriculture) - "Experiences with Drosophila suzukii and other new pests in Swedish berry production."

We especially encourage talks on:

  • new methods and tools for controlling, monitoring or forecasting (including damage thresholds)
  • IPM guidelines and audits in the different countries
  • growers’ adoption of IPM
  • pesticide situation in Northern zone (resistance and few products for minor crops)
  • breeding for plant resistance
  • emerging pests
  • interactions between pollinators and plant protection practices.


Posters on all topics relevant to the seminar title are welcome.
