On 22 April 1968, the inaugural meeting of the "Pesticides" working group of the then "Food Chemistry and Forensic Chemistry" specialist group was held in Frankfurt am Main under the chairmanship of Prof. Dr. Dr. Diemair. At that time, the working group consisted of three representatives each from universities, industry and food testing institutes, two freelance chemists and one employee of the then Federal Health Office. The first tasks of the newly founded working group included the drafting of implementing regulations for the National Maximum Quantity Ordinance for Pesticide Residues, which came into force in 1968, and the development of a recommendation on pesticide analysis with information on the equipment of a pesticide laboratory, sampling and coordination with other offices.
In the meantime, the "Pesticides" working group has developed into the largest and oldest working group of the Food Chemistry Society with around 20 active and almost 50 corresponding members. The meetings usually take place twice a year. The 100th meeting will therefore take place this year on 11 and 12 November in Kassel. To mark this anniversary, the members of the "Pesticides" working group have decided to organise this meeting as a celebratory meeting.
Active members, former active members and corresponding members are invited to the celebratory meeting. The programme of the festive meeting includes various keynote speeches, which will reflect the different areas of work of the WG in addition to the historical development. In the evening, an exchange of information is planned in a convivial atmosphere with all participants.
