The annual Conference on Tropical and Subtropical Agricultural and Natural Resource Management (TROPENTAG) is jointly organised by the universities of Bonn, Göttingen, Hohenheim, Kassel-Witzenhausen, Hamburg, Zurich as well as by the Council for Tropical and Subtropical Research (ATSAF e.V) in co-operation with the GIZ Advisory Service on Agricultural Research for Development (BEAF).

The DPG supports the Tropentag ideally and financially. Furthermore, the working group "Phytomedicine in the tropics and subtropics" performs a plant protection session at the Tropentag.
