Integrated control in protected crops, Temperate and
Mediterranean climate

End of August, beginning of September, 2021


Dear colleagues and friends,

Due to concerns about the present spread of Covid-19 worldwide and in lack of elements that could allow to predict when and how the current health emergency will go to an end, the Organizing Committee of the joint meeting of the IOBC/WPRS working groups “Integrated control in protected crops, Mediterranean climate” and “Integrated control in protected crops, Temperate climate”, initially planned to be held in Brest (France) from 31st August to 3rd September 2020, after also hearing the Liaison Officers of the two working groups, decided to reschedule the meeting to likely the same week (late August – early September) of 2021. Information on the exact dates will follow soon in a third announcement which will be distributed during the next weeks.

Abstracts already presented by participants and accepted (as both oral and poster contributions) will remain valid, unless someone wants to slightly modify them considering the one year delay of the meeting and the possibility to get additional field and/or experimental data. In this case, after the exact new dates of the meeting will be decided, participants will be acknowledged by the third announcement with a new deadline for presenting eventually modified abstracts (no presentation of a modified abstract means that the previous one will be maintained).

Regarding the presentation of full papers, the deadline of 30th March 2020 is cancelled. A new deadline (15th February 2021) will be communicated with the third announcement.

No changes will occur in the student travel grants and the student awards.

Very sorry for being forced by the events to take this decision, we hope that this negative period can end soon, while we wish you, your families, your friends and your colleagues to remain healthy and overcome this sad emergency.

Best greetings and see you all in Brest in 2021.

France has both temperate and mediterranean climate, this is why we are happy to welcome you to the meeting on integrated control in protected crops gathering temperate AND mediterranean climate, in Brest. It will take place at Le Quartz, located in the city center. Brest is located in the east of Brittany, in northern Finistère. It is a seaport city at the northwestern tip of the Armorican peninsula. Brest is easily accessed by train service and plane.


Expected themes

This event is an opportunity to promote research, development, implementation and training of Integrated Pest Management (IPM) systems in protected crops, and to promote cooperation between scientists, advisors and producers working in this field. Scientific presentation and talk will be combined with social events to encourage discussions between participants and to share ideas and knowledge.

The following themes will be addressed at the symposium:

  • New natural enemies, new pests
  • New pests
  • Food supplementation
  • Role of the plant in IPM (induced and/or genetic plant resistance, plant nutrition)
  • Biocontrole:
    » Research impact: adoption rate (% growers using, why, why not, economic approaches)
    » Microbes (biopesticides, biostimulants)
  • IPM and environment (light etc.)
  • Microbiotes around roots, plants or parasites which help plants to defend themselves
  • Phenotypes

Official Language

The language of the conference is English.

IOBC-WPRS aims and objectives

IOBC-WPRS promotes the use of sustainable, environmental safe, economically feasible, socially acceptable, control-methods of pests and diseases of agricultural and forestry crops. Therefore IOBC-WPRS encourages collaboration in the development and promotion of Biological and Integrated Production systems.

IOBC-WPRS fosters research and practical application, training and information, especially of biological methods of control, but also of all methods, including chemicals, within an integrated pest management context.

IOBC-WPRS elaborates guidelines for integrated production of agricultural crops, develops and standardises methods of testing effects of pesticides on beneficial species.

IOBC-WPRS offers presentation platforms (workshops, symposia, proceedings, publications) to scientists involved in research to improve agricultural crop production using methods and strategies in agreement with overall goal of IOBC. IOBC-WPRS helps implementing scientific knowledge into the advising and executing biological and integrated production. (source:
