In 1992 the Swiss Federal Research Station for Agroecology and Agriculture evaluated various expert systems for herbicide treatments in field crops. The Danish programme "PC Plant Protection" was chosen for further development in Switzerland, owing to its ability to select the most appropriate herbicides and application rates to control the weeds present. For the programme to work properly it is necessary to have data from field trials with reduced herbicide application. The original Danish version was tested in Switzerland in 1992 and it was found that the doses could be considerably reduced with a sufficient effect being maintained. Unfortunately, the weeds and herbicides used in this computer version did not reflect the weeds and flora and approved herbicides in Switzerland. Between 1993 and 1995 we tested a version adapted to Swiss conditions. The missing information had to be estimated by extrapolation. Therefore, the reduction of application rates was less satisfactory with this version. Since 1995 eleven European countries have been working together in an EU concerted action to further develop the programme.
