EPPO Extrapolation tables for minor uses

 

 

Background

What are minor uses?

Minor uses are those uses of plant protection products (defined in relation to crops and pests) in which either the crop is considered to be of low economic importance at a national level (minor crop), or the pest is of limited importance on a major crop (minor pest). It should be noted that a minor use in one country may be a major use in another country, and it is for each country to define what its minor uses are.

 

 

 

 

 

Development of mitigation strategies

The availability of plant protection products to growers of minor crops is becoming increasingly limited. Given the low quantity of a plant protection product that would be used for a given minor crop, agrochemical companies find it difficult to justify the registration costs. The requirement to generate a considerable amount of data makes the authorization process very expensive. However, minor crops are of substantial economic importance in many countries. For minor use authorization, it was therefore considered to be preferable exploring other possibilities for determining the efficacy and crop safety of a plant protection product than those based on the amount of data normally required. In this context, extrapolation of authorizations given to some crops to minor crops has been proposed as an option to simplify the registration process, while ensuring that sufficient data could still demonstrate the effectiveness and crop safety of the plant protection products studied. 

 

EPPO and the UE Minor Uses Coordination Facility

Since 2003, EPPO has been working on minor uses by organizing conferences and workshops on this topic, by developping Standards about the principles of efficacy evaluation for minor uses and by preparing extrapolation tables. In 2015, at the initiative of the European Union and EU and the governments of France, Germany and the Netherlands, the EU Minor Uses the Facility (MUCF) was created and it was agreed that it should be hosted by EPPO in Paris.  specificially address the issue of minor uses for Europe. A large part of the work on minor uses is now undertaken by MUCF but EPPO continues to develop standards and extrapolation tables for minor uses.

EPPO Standards related to minor uses

In 2003, EPPO published a standard (PP 1/224) describing the principles for determining the requirements for efficacy evaluation for minor uses of plant protection products in a registration procedure.  This standard provides a definition of minor uses and guidance on where to seek data to demonstrate effectiveness and crop safety, in order to simplify the registration process. However, it does not cover other minor use considerations such as residues and ecotoxicology. In 2007, another standard (PP 1/257) was prepared to provide further guidance to regulatory authorities and applicants in the context of the registration of plant protection products for minor uses, and also to provide detailed lists of acceptable extrapolations.

 

  • PP 1/224 – Principles of efficacy evaluation for minor uses
  • PP 1/257 – Efficacy and crop safety extrapolations for minor uses.

 

The lastest versions of the above standards can be accessed from the EPPO database on PP1 Standards 

 

 

 

Extrapolation tables

EPPO extrapolation tables should be used in conjunction with EPPO Standard PP 1/257 Efficacy and crop safety extrapolations for minor uses. The tables below provide detailed lists of acceptable extrapolations organized by crop groups or pest groups for regulatory authorities and applicants in the context of the registration of plant protection products for minor uses. 

 

Important note:  All extrapolations should be viewed on a case-by-case manner and expert judgment should always be applied when employing these tables. EPPO excludes liability as to the reliability of the information provided through these tables.
