Minor uses of plant protection products and extrapolation tables

 

 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 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 (each country is responsible for defining its minor uses).

 Limitations in plant protection
EPPO countries presently face problems in terms of crop protection product availability for minor crops. The processes of the current EU review of active substances and the rationalization of uses supported by approval holders are removing more and more useful products from the market. As a consequence, there are few products available even for some major uses.This concern was also expressed at our workshop on insecticide resistance in pollen beetle on oilseed rape regarding the impacts on the available resources for resistance management. Therefore, from the EPPO perspective, the minor uses of significance are those for which there are insufficient plant protection product uses, and the focus of the extrapolation work aims to mitigate these limitations.

 The development of mitigation strategies and tools
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. The 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. The Standard does not cover other minor use considerations such as residues and ecotoxicology.

Minor uses have also become an international issue and cooperation between countries has increased remarkably in recent years. However, coordination between all interested parties still needs to be facilitated and improved. In October 2006, EPPO organized a Workshop on Mutual Recognition of Minor Uses. The workshop addressed problems related to the authorization of minor uses and explored the opportunities for solutions based particularly around different forms of international cooperation, such as mutual recognition of authorizations and cooperation in data generation (view the Workhop conclusions and recommendations).

One of main strategies proposed in order to address efficacy data requirements is to extrapolate from extant registered uses, and this was elaborated in a new EPPO standard (PP1/257) published in the Bulletin OEPP/EPPO Bulletin Vol. 37(3), December 2007.

 

 Extrapolation tables
The extrapolation tables should be used in conjunction with EPPO Standard PP 1/257 Efficacy and crop safety extrapolations for minor uses. The tables provide detailed lists of acceptable extrapolations organized by crop groups for regulatory authorities and applicants in the context of the registration of plant protection products for minor uses. It is important to ensure that expert judgment and regulatory experience are employed when using these tables. EPPO excludes liability as to the reliability of the information provided through these tables. 
All extrapolations should be viewed on a case-by-case manner and expert judgment should always be applied when employing these tables.

EU
The European Minor Use Database (EUMUDA) www.eumuda.eu was developed in cooperation of the Julius Kühn-Institute and the Dienstleistungszentrum Ländlicher Raum Rheinpfalz. Its aim is to improve the cooperation between the EU Member States in the field of Minor Uses. The user can query the following information: registrations of the member states, national lists of minor uses, national lists of crop acreages, lists of available efficacy and residue trials, lists of national and common projects for closing minor use gaps.

The report of the study related to “the establishment of a EU fund for minor uses in the field of PPP”  is  now  publicly available at DGSANCO http://ec.europa.eu/food/plant/protection/evaluation/placing_market_en.htm.
