Use of the document

The comparable climates on a global level were deﬁned in com-

parison with the four climate zones within the EPPO-zone: the

Mediterranean zone, the Maritime zone, the North-East zone,

and the South-East zone.

This standard aims to assist both Authority and Applicant in

determining the relevance of the climatic conditions in one area

to another. It speciﬁcally addresses the issue of climate and pre-

sents agreed deﬁned zones in and beyond the EPPO region

within which conditions are considered climatically comparable.

The text provides general guidance; however, localized points

may have microclimates atypical of the broader local conditions.

Applicants can use this standard by referring to the deﬁned

zones rather than making a detailed case involving the submis-

sion of meteorological data. Resources are saved for all parties,

because such cases will not have to be re-submitted (or evalu-

ated) with each application.

The document may be used to justify, from a climatic perspec-

tive, the relevance of data generated outside the EPPO region to

the different zones within the EPPO region or to a particular

country. However, it is very important to remember that, even

when climatic conditions are not comparable, use of the data

may still be acceptable if it can be justiﬁed.

Minor uses of plant protection products

Minor uses are uses of plant protection products (PPPs) (deﬁned

in relation to crops and pests) in which either the crop covers a

limited area of production at national level (minor crop), or the

pest is of limited importance in 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).

It is necessary to collect efﬁcacy data for minor uses, but the

opportunity to use data from ﬁeld trials beyond the EPPO region

may be particularly beneﬁcial in enabling minor use authoriza-

tions to be granted more efﬁciently.

Comparable climates

Climate is only one factor that may affect the efﬁcacy and crop

safety of a product. The Applicant still needs to address any other

relevant factors (e.g. agronomic, edaphic, target-related) when

establishing the relevance of data generated within different

countries. The relative importance of each condition will depend

on various factors including mode of action of the active

substance, formulation type and intended use.

Deﬁned zones

The comparable zones have been deﬁned by taking into account

the agro-meteorological data (including temperature, dew-point

temperature, relative humidity, precipitation, short-range radia-

tion and frost-free period) of the ERA-40 data [ERA-40 = the

ReAnalysis of the European Centre for Medium-Range Weather

Forecast (ECMWF)]. The ERA-40 data for the four EPPO zones

were compared to the ERA-40 data from other agricultural

regions worldwide. Regions with comparable climates were
