Ragweed – A succesful story

Tackling ragweed:
a multidisciplinary and international approach


After the first International Ragweed Congress in Budapest in 2008 with Tamas Komives, the second one we organized in Lyon in 2012 and the last one in Rho (Milano) organized by our past president Maira Bonini, we have decided to organize a new International Ragweed Congress in Budapest in September 2022, 8-9th

The title of this congress will be RAGWEED: A SUCCESFUL STORY – Tackling Ragweed: a multidisciplinary and international approach.

On this page, you will find all the information you need to participate to the congress: venue, accommodation, “call for abstract” and registration form.

We hope that a lot of scientists, engineers or personalities will join us in Budapest.

When you travel directly from the airport, take bus 200E at the airport (the bus stop is located between Terminal 2A and Terminal 2B) and travel until you reach the final station (Kőbánya-Kispest). Here take metro 3 (M3) until Nagyvárad tér, whereNational Public Health Center.is located. Total time between airport and congress venue is cca. 50 min. If you come from the city center, then reach Nagyvárad tér (metro M3), there is only a 2-3 min walk from the underground station to the workshop venue. Metro 3 repalcement bus (M3) is also available.

You can enter to the territory of the National Public Health Center through the gray building located in Nagyvárad tér 2 (‘T’ building). Please indicate at the reception that you arrived to the IRS congress meeting and they will let you in. The workshop is located in the ‘T’ building on the ground floor. Signs will help you to find the connference hall.


The capital of Hungary, known by many as the “Pearl of the Danube”, is undoubtedly one of the most beautifully located cities in the world. The River Danube runs through the middle of the metropolis of two million, dividing hilly Buda with its narrow-cobbled streets and mixture of mediaeval and neo-classical buildings from the flat area of Pest with its wide boulevards. The picturesque panorama offered by the river and its bridges, the Parliament building, the imposing Royal Castle, the Fishermen’s Bastion and the impressive Danube Embankment led UNESCO to place this site on the World Heritage list.

Visitors will find side by side the remains of fortresses and buildings from Roman times, still-functioning Turkish baths, Gothic and Baroque buildings, and the incredibly rich Art Noveau architectural heritage. There is no other capital city in the world which can boast close to 100 thermal springs and 12 medicinal baths, where 19 million gallons of thermal water rise to the surface each day.

It is a city where the pleasing harmony of different architectural styles and superb structures, the cafés, gastronomy and culture are combined with the legendary Hungarian hospitality, blending into an unforgettable experience for visitors.

Budapest is the venue for numerous congresses, international meetings, sports competitions and cultural events, with its developed infrastructure, elegant shops and modern hotels. Budapest’s cultural life is widely renowned, with more than 20 theatres and also ample to explore!
