15. 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

16. 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

17. 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

18. 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
