Today the IIRB has about 350 members from 27 beet growing countries. Austria, Belgium, Denmark, France, Germany, Great Britain, Sweden and The Netherlands are represented in the Administrative Council (AC).

The AC administers the IIRB. The President of the IIRB is elected for a period of two years among the members of the AC. The AC is assisted by the Secretary General and relies on the Scientific Advisory Committee (SAC) for advice on scientific matters. Eight study groups are working under the auspices of the Scientific Advisory Committee. Their aims are to exchange information between specialists on topical subject matters and to provide a network for carrying out joint technical and scientific research projects.
