Training course 2: Pesticides
17 to 20 November 2014

Specific objective
The overall objective of this workshop is to train people working with pesticides either as an authority or as stakeholder, in the principles, concepts and methods of legislation, authorisation and control of pesticides. It is the objective to provide the participants with theoretical and practical knowledge and experience in these areas. The practical experience will be gained through the use of visit to a company and real-life cases during the training.
The training workshop will cover the “life-cycles” of a pesticide. This includes:
  • Toxicology and Good Agricultural Practice
  • Setting of Maximum Residue levels including toxicological evaluation
  • Use
  • Control
  • Exposure
The complexity level of the workshop will be adapted to the participants’ experience in pesticides, which will be accessed beforehand.

Specific learning objectives for the workshop
At the end of the workshop, participants will be able to:
  • Recognise the EU and Codex legislation on pesticides incl. where to find relevant MRL and residue definitions
  • Know the requirements of evaluations for pesticides
  • Recognise how a MRL is set and calculate a MRL
  • Identify the relevant information for authorisation and use of pesticides
  • Relate the principles learned about sampling to national conditions
  • Construct a basic sampling plan for the country.
  • Identify uncertainties in sampling
  • Find relevant part of commodities to analyse
  • Discuss advantages/disadvantages of different analytical methods
  • Identify the requirements for the best analytical methods taking into account substance, commodity as well as the analytical capacity of the laboratory
  • Identify uncertainties in the analytical work
  • Interpret the results and uncertainties in the analytical work
  • Transfer or apply requirements of quality assurance for analytical methods to the national/laboratory level
  • Calculate the exposure of pesticides according to the principles of Codex/JMPR/EFSA
Organization of the workshop
The workshop is planned as a combination of theoretical lectures in plenum, exercise/case work and discussion sessions. A visit to a market, harbour etc. will be included as a case work concerning sampling procedure. In general, the lectures will be kept short and to the point in order to prioritise time for questions/discussions, cases, and exchange of views and feedback between the participants and tutors.
It is important that experience from the participants is used in the workshop. Before the workshop, a questionnaire will be sent to the participants to assess their previous knowledge of the different subjects of the workshop. This will allow the tutors to adapt the level of the workshop and to focus on particular needs of the participants. In the case that the prior knowledge areas and levels are very dispersing among the participants; this will be taken into account.

The overall aim of the theoretical component of the workshop is to provide so much knowledge on the different subjects so the participants can use and apply it to their everyday work. The theoretical review will be complemented with practical short examples/exercises / case works based on situations from the Tutors everyday work. A visit to a market, harbour etc. where the principles about sampling can be shown, will be included. It will be encouraged that the participants explain the conditions and challenges in their country/institution so the lectures can take these conditions into considerations in the lecture and in this way make the workshop more focused on the local problems.
The theoretical component of the workshop will cover the following topics:
  • Data requirements for evaluation of pesticides
  • Toxicological evaluations of pesticides and setting ADI and ARfD
  • How is a MRL set
  • Risk assessment of MRLs
  • Monitoring and control sampling plans
  • Sampling procedures
  • Analytical multi residue methods
  • Analytical single residue methods
  • Validation and quality assurance
  • Proficiency tests
  • Reference laboratory system
  • Interpretation of analytical results
  • FVO mission
  • Exposure assessment both chronic and acute
Exercise/Case work
The time allocated to exercise and case work will be balanced with the theoretical lectures in order to provide participants with the opportunity to apply the knowledge acquired in each day. These cases will be inspired by existing problems and cases from the tutor’s everyday work. It will be possible and welcomed if the participants have cases they want to discuss. The case studies will include examples from all the subjects included in the programme and it will be will be simplified in order to allow the participants have time to apply all the methods within the timeframe of the workshop. The cases will include the calculation of MRLs; find relevant MRLs, design of sampling plans, sampling procedures, sample preparation, interpretation of analytical results, uncertainties in analytical results and preparation for FVO missions.
The case work will take place in smaller groups. These groups will be formed based on the participants’ knowledge and language skills and sometimes their field of work. It is our experience from previous courses that the participants target group will be more active in the group discussions if they work together with other participants speaking the same language, so interpretation will be kept at a minimum during the group work.

Plenum discussions
All sessions will end with a plenum discussion facilitated by the tutors. Participants are encouraged to comment on any aspect within the topic discussed. However, to improve the relevance of the workshop for the participants, they are asked to raise issues of particular interest to them, for example the authorisation of a pesticide or how to choose the most appropriate analytical method.
Time will be allocated for the participants to present problems during plenary discussions and thereby enhancing discussions regarding harmonisation and best practice approach to resolving the problems. Issues raised by participants in the reply to the questionnaires handed out before the workshop and not handled during the lectures or group work will be discussed in the plenum sessions.
The discussions will give the participants a better understanding of the challenges connected with addressing problems concerning authorisation, sampling, analysis and evaluation of pesticides. Given the different background of the workshop participants, the discussions will also provide ideas and tools on how to manage national or regional issues.

Written material
Presentation and written material presented in lectures will be submitted to participants according to BTSF time lines.

Teaching form
Throughout the workshop the aim of the activities is to give a short and clear theoretical introduction to the subject and link it up to practical examples. The participants will be given cases they will discuss in groups and finally in plenum. Also a visit to an enterprise will be included if possible. This form of teaching will encourage the participants to use the methods learned during the workshop. Furthermore the participants will work together and thus build a network, which they can use when returning to their work places.
