Workshop on Pesticide Indicators 2008, Malta Main findings Methodology for the implementation of the proposed Regulation on plant protection products has been worked out Dataset on PPP usage covering the whole national production has been obtained Calculation routines have been set up Workshop on Pesticide Indicators 2008, Malta

Workshop on Pesticide Indicators 2008, Malta Problems encountered Quality of filled questionnaires was not equally good The most appropriate time for interwieves has not been chosen The most difficult stage during the data processing was the cooperation with programmer because very specific area of the work had to be done by programmer In a small country only few experts are involved in the project and in the case if some of them leaves the team problem is the replacement Workshop on Pesticide Indicators 2008, Malta

Lessons learned for the future Interviewers must be better trained in fill in the questionnaire accordingly to the guidelines. Representatives from CSB must be involved in the training process Carefully should be checked commercial names of products and active substances taken into account a simple differences in prefixes and suffixes As the survey for the implementation of new regulation requirements is foreseen to be carried out once a year for all crops it should be a computer assisted survey (using lap-tops in interviews Workshop on Pesticide Indicators 2008, Malta

Lessons learned for the future (continued) The best solution would be to set up the local legislation act with the obligations for Plant Protection Service to keep up electronic data base, and PPP users once a year must be obliged to send the data on used plant protection products Workshop on Pesticide Indicators 2008, Malta
