100th meeting (fixed meeting)

On April 22, 1968, the constituent meeting was the working group "pesticides" the former Division of "food chemistry and Chemical court" under the chairmanship of Prof. Dr. Dr. Diemair in Frankfurt / M. instead of. At that time, the working group consisted of three representatives each from universities, industry and food testing institutes, two freelance chemists and an employee of the then Federal Health Office. The first tasks of the newly founded AG included the elaboration of the implementation provisions of the national maximum amount regulation for pesticide residues that 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 AG ?pesticides? has developed into the largest and oldest AG of the Food Chemical Society with around 20 active and almost 50 corresponding members. The meetings usually take place twice a year. The 100th meeting this year will take place on November 11th and 12th in Kassel. On the occasion of this anniversary, the members of the ?pesticides? working group decided to design this meeting as a festive meeting.

Active members, former active members and corresponding members are invited to the ceremony. The program of the festive meeting includes various festive lectures, which, in addition to the historical development, will reflect the different areas of work of the working group. In the evening, an exchange of information in good company with all participants is planned.
