The 30th anniversary of the Trans-Tisza Plant Protection Forum (30th TNF) was jointly organised by the Faculty of Agricultural, Food and Environmental Sciences of the University of Debrecen (University of Debrecen) and the Sapientia Hungarian University of Transylvania (EMTE) on 15-16 October 2025 in Târgu Mureș. The Plant Protection Forum, which has been held continuously for three decades (raised to an international level every three years during the period), will be held annually from 2025. Consequently, the 30th TNF was also the 12th IPPS (International Plant Protection Symposium). In 1868, higher education for farmers was launched in the Trans-Tisza region to create the best, always modern agriculture. To help with this, we started the series of TNF (IPPS) events in 1996, the aim of which is to combine the results of modern science with Integrated Pest Management (IPM) and the plant protection of organic farming systems (Eco-Farming), which continue to be offered in the city of Debrecen in the future.
