Workshop on efficacy requirements and evaluation of plant protection products based on low-risk active substances
Ede, NL, 2016-04-06/07
A Workshop on Efficacy requirements and evaluation of plant protection products based on low-risk active substances was held on 2016-04-06/07 at the Conference Centre ‘De ReeHorst’, Ede, The Netherlands. It was jointly organized by the National Plant Protection Organization of the Netherlands (NPPO), the Board for the Authorisation of Plant Protection Products and Biocides (Ctgb), International Biocontrol Manufacturers Association (IBMA) and the European and Mediterranean Plant Protection Organization (EPPO).
There were 113 participants from 19 EPPO countries, Canada, the European Commission, EU Minor Use Coordination Facility, manufacturers of biocontrol solutions, agrochemical companies and consultancy firms.
This Workshop provided an excellent opportunity to share experiences and discuss issues preventing quick authorization of plant protection products based on low-risk active substances as well as possible solutions. The Workshop included a lecture session, smaller working groups and a plenary discussion session. All presentations can be viewed below.
The participants were welcomed by Mr van Duijn (Director Ctgb,NL) and this lecture session was chaired by N. Roozen (NPPO, NL)
Introduction on the Workshop’s scope
- Efficacy and low-risk products (including background on the Green Deal) - J. van Etten, Ctgb, NL and C. Jilesen, NPPO, NL
- Efficacy requirements of plant protection products based on low-risk active substances - C. Jilesen, NPPO, NL
Determining Value of Low-risk Pest Control Products in Canada - P. Curry, PMRA, Canada
Efficacy for low-risk PPPs – an industry view - D. Cary, IBMA
Contribution of the Expert Group on Sustainable Plant Protection - R. van Drent, DG SANTE, EU Commission
Working group sessions
Workshop participants were divided into five groups for the working group sessions. The following subjects were discussed in all groups:
- Acceptable effectiveness levels and types of label claims.
- Dose justification.
- Data requirement: what is the minimal amount of information to do a meaningful efficacy evaluation?
- Extrapolation possibilities/ justification of extrapolation.
- Quality of dossiers/ role of applicant.
- Usefulness of Value Assessment.
On the final day the rapporteurs of each group presented their group’s conclusions to the plenary session:
- Group A - Low risk (bio)chemicals/botanicals /minerals
- Group B - Low risk micro-organisms with direct mode of action e.g. insect- and fungal pathogens and baculoviruses
- Group C - Low risk micro-organisms with indirect mode of actions e.g. acting through population regulation processes (competition for space/ resources), host plant
defence induction, endophytes
- Group D - Pheromones and other semiochemicals
- Group E - Low risk and efficacy policy group
