20th International Reinhardsbrunn Symposium
Modern Fungicides and Antifungal Compounds
23. April - 27. April 2023
Friedrichroda - Germany
Thank you for visiting the Reinhardsbrunn-Symposium-Website.
Please scroll down for detailed information about and registration for the 2023 symposium, as well as for the archives of former symposia
For over 50 years the name "Reinhardsbrunn" has become famous in scientific circles for the Symposium series which draws together fungicide scientists from academia, research institutes and industry to present, listen to and discuss the latest research findings from around the world in this fast moving field.
Such research is a vital component in the quest to provide adequate control of the fungi that threaten the world's food supply and commodity products. Only by discovering new active molecules by synthetic chemistry or from natural sources and by understanding how they work and how best to use them in geographically different locations, can we hope to maintain and improve the quality of life for the world's growing population.
The 2023 Symposium will build upon the Reinhardsbrunn reputation by providing an opportunity for established experts and those just starting on their scientific career to present information to an international audience through oral presentations and posters. In addition, outstanding experts as key note speakers will introduce into the symposium and the single topical sessions. There will be ample time to discuss the findings and their implications both during and after the presentations. The Symposium thus also provides a unique opportunity to establish new contacts and friendships within fungicide science.
It is the intention of the Symposium Committee to arrange a well balanced program with participants and perspectives from around the globe, and sufficient time for discussion.
We look forward to welcome you as an active participant at the next symposium.
The official language of the symposium is English.
The following experts from around the world have agreed to provide keynote lectures.
Confirmed keynote speakers for April 2023 are:
Prof. Fiona Burnett, Scotland’s Rural College, Edinburgh, United Kingdom
Prof. Lise Jörgensen, Aarhus University, Denmark
Prof. Xili Liu, China Agricultural University, Beijing, China
Prof. Nick Talbot, The Sainsbury Laboratory, Norwich, United Kingdom
Prof. Eckard Thines, Johannes Gutenberg-Universität Mainz, Germany
Prof. Andreas v. Tiedemann, Georg-August-Universität Göttingen, Germany
Project No. DE 403/23-1

In addition to invited lectures the symposium will be based on oral papers and posters accepted by the Symposium's Committee from submitted proposals. Presentations will be accepted from areas of fungicide science that fit into the following thematic areas:
- Fungicide resistance
- monitoring: regional and global aspects
- mechanisms and diagnosis
- molecular mechanisms
- risk assessment
- risk management
- New fungicides, technologies, and applications
- Bio-rational fungicides / biocontrol
- Resistance modelling
- Digital pathogen and resistance sensing
- Regulatory aspects
- Molecular Crop Protection
- Other fungicide-related topics
The Symposium will be held at the H+-Hotel (former Ramada), Thüringer Wald in Friedrichroda, Germany. The Hotel offers a special accommodation package on a first-come, first-served base at a special price (see "Fees") which includes breakfast and room.
In case the H+ Hotel is fully booked, nearby Ahorn Berghotel Friedrichroda (5 minutes walking distance) is an alternative.
How to get to Friedrichroda:
By plane to Frankfurt/Main, Berlin or Erfurt.
From there by train to Gotha (Thuringia), which is situated on the railway line Berlin - Frankfurt (check with: www.bahn.de; English version: https://www.bahn.com/en.)
In Gotha take a taxi : costs from the station Gotha to the hotel will be approximately € 45,-. Adventurous participants take the local tram in Gotha (Thüringer Waldbahn) to the station "Bahnhof Reinhardsbrunn". The Hotel is within 500 m walking distance up the hill.
By car from Frankfurt/Main: take the Autobahn (Expressway) A5 -> A4 to Eisenach and Erfurt, branch off at Waltershausen. Then follow the signs to Friedrichroda.
Passport and Visa
Members of the European Union need a valid identity card or passport. Participants from all other countries should check with their travel agency or directly with the German Embassy in their home country for visa regulations.
