Efficacy Data and Information (including Value Data) on the
Plant Protection Product (KCP 6)
EU guidance SANCO 10055/20131 describes the principles and framework for zonal efficacy product
evaluations, including the differentiation between core zonal assessments, and individual Member State
(MS) National Addenda.
This document specifically addresses the requirements of a Part B, Section 3 (Efficacy Data and Information) draft registration report (dRR) where a UK National addendum is required. It contains
guidance (under the relevant sections) on the very limited number of UK-specific efficacy issues that
may require specific supporting data, if not already sufficiently covered in the core zonal dossier. Or in
relation to those issues where there is no agreed EU/EPPO guidance and relies on any National requirements (e.g. convenience tank mixtures; supporting IPM claims). One of the main objectives is to
highlight the general information that will assist HSE-CRD when acting as a concerned MS, authorising uses based on the zRMS core assessment (Article 33applications), and guidance on putting the core
zonal assessment into context for a UK authorisation. In doing so, it brings together into one document
the various specific UK labelling requirements relating to efficacy that should be considered when
drafting the UK label. References are also made to UK resistance management restrictions and labelling. (See 3.2 for further explanation).
(The information and examples provided in the template and guidance notes for the core Part B,
Section 3 are not repeated in this document. Only the information that could be helpful in the
preparation of a UK national addendum is provided).
Article 33 authorisations including UK-only uses
As part of a zonal application, National addenda may be used to support a specific use in one of the
individual concerned MS. Please refer to SANCO 10055/2013 regarding the appropriateness of recommending a specific use (crop and/or target/different dose) in an individual MS. (If the proposed use
were to represent the ‘worst case risk envelope’ in any area of the risk assessment it should be considered in the core). Any additional UK uses should be clearly highlighted and explained in the UK National addendum, and supported by appropriate data.
Please note that the UK view is even data/information supporting uses intended for only one MS
should still usually form part of the core zonal consideration. This is because there will often be
relevant associated data in the core, whether it is on other targets and/or other crops, which strengthen
the supporting evidence both for effectiveness and crop safety. The zRMS should evaluate the data
even if a final conclusion is dependent on National cMS consideration. Circumstances where it may be
relevant to submit a UK National addenda could be based around a lower dose due to specific UK risk
assessment considerations; data protection related issues/bridging to a UK-specific product. If submitting a UK National addendum for a specific use, applicants are strongly encouraged to cross-reference
to relevant parts of the core assessment. For example, various aspects of crop safety and unintended

side effects, and resistance management, may be appropriately addressed by information in the core.
This document is also relevant and may be used if applying for an Article 33 authorisation where the
UK is the only requested MS.
Article 40 Mutual Recognition Authorisations
This guideline may also be relevant for applications for a UK authorisation, based on Mutual Recognition of another MS authorisation. In particular, consideration should be given to the relevance of agronomic conditions (including pest/crop) to the UK, UK resistance management, and any other UK specific requirements.
This is a working document, and will be revised over time as experience of zonal product assessments
develops. It will also reflect any longer term initiatives to harmonise approaches in some of the
specific areas discussed below, where there is currently no EU guidance.
Notes: Text shaded turquoise provides general information/support and should be deleted when the
document is finalized. Text highlighted in yellow should be changed as specified; it shows example
text. Explanation may be added and text that is not relevant may be removed. Text in black shows the
headers for each section. It also shows example text and can be changed if necessary.
Fields shaded in grey are reserved for HSE-CRD assessors and should not be filled in by the applicant.

Efficacy data (KCP 6)
This national addendum has been prepared for the evaluation of <insert product code/name> for the
Netherlands. This national addendum should be read in conjunction with the core assessment part B, Section 3 Efficacy.
While there is no requirement to automatically submit National Addenda there may be specific MS
issues relating to certain proposed uses, requiring at least some further explanation if not fully addressed in the core assessment. It is envisaged, however, that generally National addenda should only
contain a limited amount of data, in support of a specific individual use or uses in a particular MS (provided within the core ‘risk envelope’).
Using a National addendum to the core dRR can be very useful for the relevant concerned MS by
providing a brief overview on how the proposed zonal uses specifically relate to those requested in the
individual concerned MS. In particular applicants should consider:

How do any proposed uses relate to relevant existing products (e.g. is the proposed dose considered in the core zonal assessment significantly different to that already approved in the concerned MS?). This is one of the commonest problems not properly considered or explained to
concerned MS. Using National addenda is particularly relevant in this context.

Applicants should consider the relevance of the proposed GAP to UK conditions. As well
as being aware of any UK statutory conditions imposed due to resistance management (see below), local target pressure will determine the number and interval of applications in the treatment programme in any one season. Broadly speaking, for many insect species in the UK there
is a tendency not to complete as many generations in a season as elsewhere in Europe. Therefore the overall spray programme may involve fewer insecticide applications, and the treatment
interval might be longer than in some other MS. Conversely, disease pressure in the UK tends
to be high, reflected by a need for shorter, more frequent applications (particularly curative) or
higher doses. For all of these aspects it should be possible to cross-reference to the core assessment and use this as the basis when drawing up UK specific recommendations.

How have the UK draft label uses and recommendations been derived from the zonal assessment

Are there particular UK issues that should be reflected in the proposed UK labels
CRD experience to date is that the above issues are sometimes poorly addressed when making Article
33 following zonal applications to CRD as a concerned MS (or Article 40 applications). This can result
in requests for further clarification, and questions may be raised over the proposed draft label recommendations.
For this reason CRD advise applicants to consider submitting a UK ‘National addendum’ (using this
dRR format). The intention is not for applicants to re-submit or re-evaluate data from the core assessment. Instead the UK National addendum should include a brief overview putting the proposed UK
uses in context, considering how they are derived from the core zonal assessment, and whether any
adjustments are needed to reflect UK conditions. This might include the proposed number of applications, and any information on thresholds for treatment.

If, for a particular target species, there is a range of different doses proposed across the zone, then an
explanation and justification of the proposed UK dose should be provided. The zonal data package, for
common uses, should be representative of the range of conditions found within the proposed zone. It
should not therefore be necessary to submit more data, but simply cross-reference to the relevant part
of the core dossier, whether they were generated directly in the UK or in a region still considered relevant to UK conditions.

UK PLANT PROTECTION PRODUCT LABELLING: Efficacy aspects
a) Relevance of proposed target species
A common problem is applicants do not consider the relevance of the proposed target species, and instead all the proposed zonal uses are included on the UK draft label. This can lead to time being spent
on trying to clarify and determine relevant UK uses. HSE-CRD has produced several UK efficacy
guidelines which give information on what are considered to be major/minor target species on some of
the most important UK crops – cereals, oilseed rape and vegetable brassicas, as well as more specialised crops (e.g. apple/pear). Applicants’ are advised to consult these when drawing up UK labels and
also when determining if the pest is supported by an appropriate number of trials (i.e is the pest major
or minor in the UK).
It is acknowledged that the pest spectra on a particular crop can change over time, as indeed can the
commercialisation of new crops in the UK. There are instances, particularly for insect pests, where the
prevalence of some existing species (or new species) is becoming more common in UK. The onus is
on the applicant to demonstrate that the proposed target species are found in the UK. It is accepted that
these instances may be sporadic, in either location or frequency over the seasons in the UK. But, to be
considered as pests, evidence is required that when the pests do occur, economic damage justifying
treatment with a plant protection product is warranted. In this regard, information provided by relevant
growers can be very helpful.
HSE-CRD operates a system of ‘qualified recommendations’ that can appear on a label, designed to
support claims for UK minor/sporadic pest species. This is in recognition of the costs of conducting
trials, and sometimes the impracticality of generating data on such species. This can also be a relevant
factor for crops not widely grown in the UK. The scheme is based on extrapolation from either limited
data (or no data) generated on relevant related crops/targets. Although it is anticipated that for zonal
authorisations, sufficient data may already be available from the core assessment (e.g generated in
areas outside the UK where the crop and/or pest is more widely distributed). Applicants should also
consult the EPPO Minor Use Extrapolation Tables, as relevant extrapolation possibilities may be specified there. If neither of these options is relevant, applicants may propose a ‘qualified recommendation’, with a reasoned case explaining how the use is being supported. These should appear on the UK
label under a heading ‘Qualified recommendation’, and a sentence noting that the relevant use (crop or
target) is based on limited effectiveness and/or crop safety data (as appropriate). For example, a qualified recommendation on leeks in addition to other fully supported label disease claims, might be described as:
‘Qualified recommendation on leeks: limited effectiveness data indicate some control of White tip
(Phytophthora porri) ( PHYTPO ). Conditions of use for leeks described in the ‘important information’ box must be followed’.
(NB in this example because other diseases on leeks were fully supported, crop safety was established
and it is not necessary to indicate ‘limited crop safety’)
(Please note that there are some common European pest species that are statutory pests in the UK subject to specific plant health measures, or on the UK Plant Health Risk register but not yet established in
the UK. Such pest species are not permitted on UK product labels, but Plant Health will be informed
on the potential availability of relevant authorisations, should control measures be required. Current
examples include Colorado beetle (Leptinotarsa decemlineata) and Western corn rootworm (Diabrotica virgifera); Japenese leaf rust (Gymnosorangium asiaticum).

b)
Claims of control
The UK also operates a system of differential claims for any particular target species, based on the
level and consistency of control. There is no need for any re-evaluation or re-presentation of data in
the UK National addendum, but applicants should draft the UK label in accordance with this scheme.
Where relevant, it may be helpful to point to the appropriate sections of the core zonal assessment to
illustrate the levels of control obtained. This is reproduced below:
1.1.1.
Insect Pests
In considering data submitted towards justification of claims of effectiveness against pests, a number of
factors will need to be taken into account when considering and interpreting the level of control
demonstrated. These include the time of assessment in relation to application, the duration of effectiveness and the potential for re-invasion, and any recommendations for repeat applications.
Table 1: Levels of pest control expected for effectiveness claims
Level of effectiveness
Label claim appropriate
Consistent control commonly above 80%
Control
Useful level of control (moderate control
may also be used)
Some control/reduction (in numbers or damage)
Control, between 60 and 80%
Lower levels of control e.g. 40-60%; lower
in exceptional cases.
For a claim for effectiveness below 80% to be supported authorisation, the level of control demonstrated for that pest must be considered beneficial for protection of the crop. For some pests particularly
those affecting the quality of the crop, higher levels of consistent control (i.e. above 85%) would need
to be demonstrated to support a claim of ‘full’ control. Examples of pests falling into this category are
pea moth and codling moth.
1.1.2.
Diseases
Disease may be assessed as either severity or incidence. Measurement of disease incidence is particularly useful when low levels of disease are present but may be of little value when infection is more
widespread, when severity is more likely to give a useful measurement of disease control. There is
normally no benefit in reporting both. Table 2 a)indicates the levels of control expected to be demonstrated to support label claims for diseases and should be used where either severity or incidence are
recorded as a percentage or other linear scale.
Table 2a) ; Levels of disease control expected for effectiveness claims
Level of effectiveness
80% and above
60-80%
40-60%
Label claim appropriate
Control
Partial/moderate/useful level of control
Reduction/some control
These criteria are not appropriate in cases where disease control is assessed as a score on a non-linear
scale. These scales are often relatively coarse with as few as four divisions. With such scales meaningful levels of control can be difficult to determine unless disease pressure is relatively high. Table 2b)
indicates the levels of control expected to be demonstrated to support label claims for diseases where
measurements are made on a non-linear scale. In addition, statistical analysis of assessments on a non
linear scale is generally not appropriate. Even the calculation of means should be avoided. When recording and assessing such results it may be better to assign letters rather than numbers to the steps on
Page 11 /23

Part B – Section 3 – UK National Addendum
the scale to avoid the temptation to analyse them numerically.
Table 2b); Levels of disease control expected for effectiveness claims when using a non-linear
scale
Level of effectiveness
Consistently reduces disease to below 2025%, normally the lowest class.
Reduces disease to<20-25% in the majority of cases
Clear reduction in disease
Label claim appropriate
Control
Partial/moderate/useful level of control
Reduction/some control
For some diseases, particularly those affecting the quality of the crop, higher levels of consistent control will need to be demonstrated. For a claim of control of seed borne pathogens (e.g. bunt, loose smut,
leaf stripe), a product needs to be 98% effective or better. For leaf stripe and loose smut, control in the
region of 85-95% would allow the claim for moderate control with the condition that seed cannot be
used for multiplication purposes.
In some cases an argument may also be made for higher claims than are justified by disease control
alone. For stem base diseases of cereals, for example, a claim of control may be appropriate even when
disease control is not consistently above 80%, if it can be shown that the treatment significantly reduces lodging and/or disease levels are kept to a level where they have no significant effect on yield.
1.1.3.
Weeds
In arable and horticultural field crops, the label claim supported by a certain level of weed control is as
follows:
Table 3; Levels of weed control expected for effectiveness claims
Label claim appropriate
Susceptible
Level of effectiveness
Consistent control of 85% and above (see below
†)
Moderately susceptible
More variable control, mean 75-85%, but with
results often above 85%
Moderately resistant
Variable control, Mean 60-75%, but some results above this level.
Resistant
Poor control below the levels given above
† To ensure worthwhile levels of control of certain important weeds in field crops, all these categories
are raised with the susceptible rating being as follows: pernicious grass weeds where seed return must
be prevented, e.g. black-grass and wild-oats, 95% and above, cleavers 90% and above.
For perennial weeds, assessments of control levels in the year following treatment will be important in
determining the claim allowed.
c)
Winter and Spring Crops
In January 2015 an important change was made to the qualifiers used to define spring and winter crops.
The qualifiers changed from being based on variety to being based on the time of year in which the
crop is planted. This change better reflected the environmental risk assessment and allowed growers
more flexibility to plant spring varieties in the autumn.
A clarification has been added to these qualifiers to highlight that application to spring varieties sown
in the winter (and vice versa) is likely to be at the growers own commercial risk. This is because crop
safety and effectiveness may not have been demonstrated on spring varieties sown in the winter (or
Product code / Product name
Part B – Section 3 – UK National Addendum
Page 12 /23
Template for chemical PPP
vice versa). The relevant phrase will be added to the label of professional products which have a specific authorisation for winter crops but not spring (or vice versa) (and which are not seed treatments),
where relevant data on all varieties is not provided.
For products authorised on winter crops:
“This product is authorised in winter sown crops. Growers choosing to apply this product to winter
sown spring varieties should note that crop safety has not been demonstrated in spring varieties. As a
result application of this product to winter sown spring varieties is done so at the growers own commercial risk (and this also applies to unclassified varieties).”
For products authorised on spring crops:
“This product is authorised in spring sown crops. Growers choosing to apply this product to spring
sown winter varieties should note that crop safety has not been demonstrated in winter varieties. As a
result application of this product to spring sown winter varieties is done so at the growers own commercial risk (and this also applies to unclassified varieties).”
(Full information on the UK Crops Definition List is available from the HSE website:
http://www.hse.gov.uk/pesticides/Crop-Definitions-List-Feb-2016-word-version-2.pdf)
d) Labelling of Molluscicide Products
In the UK traps baited with molluscicide pellets were historically used to assess the risk of damage in
cereals by estimating slug populations. The potential hazard to wildlife meant this practice was
stopped and has been replaced with non-toxic chicken layer's mash (commercial poultry food). A research project calibrated the method using this bait to establish a threshold for winter wheat and established a relationship between numbers trapped in cereal crops and stubble prior to drilling winter
oilseed rape.
The method and relevant thresholds are published on the Agriculture and Horticulture Development
Board (AHDB) website. The following label wording must appear on all professional molluscicide
products:
“For further information on slug trapping and damage risk assessment, please refer to AHDB Information Sheet 02 ‘Integrated slug control – risk assessment and monitoring slug damage’, available on
the AHDB website’
In addition, there are further advisory paragraphs which applicants can choose to add:
a) For product labels that wish to include specific information on damage risk assess-
ments using bait trap methods in winter wheat and winter oilseed rape, the following,
or words of similar meaning, can be added.
“To establish the need for pellet application on winter wheat or winter oilseed rape,
monitor for slug activity. Where bait traps are used, use a foodstuff attractive to slugs
e.g. chicken layer's mash which has proven to be particularly effective. D0 NOT use
slug pellets as bait in traps since they are a potential hazard to wildlife and pets.”
Product code / Product name
Part B – Section 3 – UK National Addendum
Page 13 /23
Template for chemical PPP
b) For product labels that wish to include details of the actual method on their product
labels, appropriate suggested wording is as follows:
“Put slug traps out before cultivation, when the soil surface is visibly moist and the
weather mild (5-25°C). Traps consist of a cover about 25cm across, with a small heap (20ml
or 2 heaped teaspoonfuls) of chicken layers' mash (NOT slug pellets) beneath. In each field,
nine traps (13 in fields larger than 20ha) should be set out in a 'W' pattern. Also concentrate
on areas known to suffer damage. Leave traps overnight and examine early the following
morning.
FOR WINTER WHEAT, a catch of 4 or more slugs/trap indicates a possible risk, where soil
and weather conditions favour slug activity. FOR WINTER OILSEED RAPE a catch of 4 or
more slugs in standing cereals, or 1 or more in cereal stubble, if other conditions were met,
would also indicate possible risk of damage.”
Introduction
The introduction should include an explanation on why the National addendum is provided, and which
areas are being addressed within this addendum, with cross-reference where appropriate to the core
dossier.
Further details about the proposed uses (GAP) can be found in Part A, or in Appendix 1 of Part B Section
0 (all MS uses).

3.2.2

Template for chemical PPP
Minimum effective dose tests (KCP 6.2)
Please refer to the core assessment Part B, Section 3.
In principle this should be addressed in the core assessment, however in some circumstances additional
information may be presented in the UK-National Addenda. In particular, applicants should consider
the relevance of the target pest and crop to the UK (i.e. major/minor?) and proposed UK GAP. If dose
ranging data in the core are not on a relevant to the UK, further data may need to be submitted in this
section.
Other circumstances may include dose expression in three dimensional crops, and if addressed in the
core in an expression not used in the UK-GAP, further justification and explanation must be provided.
This particularly applied in pome fruit, where EPPO PP 1/239(20 recommends using amount/ha leaf
wall area (LWA), but UK labels express as amount/ha (see 3.2.3).
3.2.3
Efficacy tests (KCP 6.2)
Please refer to the core assessment Part B, Section 3.
a)
General
UK follows EPPO standards in relation to the zonal principles and numbers of trials, depending on
whether a major or minor pest and/or crop. Applicants should also refer to the relevant EPPO Minor
Use Extrapolation tables and associated EPPO1/257 ‘Efficacy and crop safety extrapolations for minor
uses’.
Where there are potential problems in supporting a UK authorisation, commonly, it is insufficient data
on target pests which are major in the UK, or the data are not typical of all conditions of the zone (i.e.
have not encompassed areas sufficiently challenging and representative of UK conditions). This tends
to apply to fungal pathogens, where UK disease pressures can be high within the Central zone, and
certain cereal diseases which are major in the UK but minor elsewhere; or weed species such as blackgrass (Alopecurus myosuroides) which is a major weed in the UK due to the heavy soil conditions (and
widespread resistance to a number of current herbicides). Applicants are also reminded that winter
sown cereals and winter sown oilseed rape predominates in the UK, which can impact on target pest
species, and should be reflected appropriately in the core data package.
As noted above, information is available in various UK efficacy guidelines on major/minor pest status
for some UK crops. Applicants should also refer to other relevant published guidance, such as Agriculture and Horticulture Development Board (www.ahdb.org.uk), which a number of detailed guidelines
on cereals, OSR, and horticultural crops, and these include information on major UK pests. For insects
in particular, the AHDB ‘Encyclopaedia of pests and natural enemies in field crops’ is a comprehensive
guide and includes where available UK treatment thresholds.
3-D crops, including pome fruit
EPPO 1/239(2) recommends leaf wall area (LWA) as an appropriate common dose expression method
for orchard trials. It also emphasises the need to record all orchard structure parameters in order to then
Product code / Product name
Part B – Section 3 – UK National Addendum
Page 15 /23
Template for chemical PPP
convert, where relevant, to any Member State national method. In the UK, dose is expressed on product labels as an amount/ha (sometimes % concentration is also included, but amount/ha is a requirement both for efficacy and other areas of the risk assessment). Therefore whilst the core dossier may
express the dose applied in the effectiveness trials as LWA, this must be appropriately converted onto
UK labels as amount product/ha.
EPPO 1/239(2) includes various conversion methods based on commonly used Member State dose
expression methods. The relevant UK conversion from LWA into product/ha is based on a standard
UK orchard structure of 3.5 m single row distance and 3 m high). It is assumed that the tree is in full
foliage (a CAF factor of 1, unless a growth stage is specified that would exclude application at full
canopy - for explanation see below). The conversion factor for a standard UK orchard (as described
above) is there are 1.7 LWA per ha (ground).
Applicants should also be aware that typical UK practice is to use lower water volumes (100-300 l/ha)
compared to other MS. The core data package should ideally include trials conducted at this lower
range, since the package should be typical of the range of conditions. Alternatively, specific UK data
using such water volumes may be included in the UK addenda.
It is recognised that growers use their experience to adjust the label recommended dose during the season in response to tree size and growth. UK funded research developed a common scheme: Pesticide
adjustment to the Crop Environment (PACE) scheme. The scheme provides a series of pictographs of
typical apples trees of different canopy density to aid assessment of the ‘Crop Adjustment Factor’
(CAF) used to calculate the applied pesticide dose in a given orchard. The label should generally recommend the higher dose applicable to a full tree height in a typical UK orchard (e.g. 3-3.5 m) at full
canopy density (CAF value of 1). (This is unless the label specifies a particular pre-blossom or early
season recommendation). Ideally the tree height should also be specified on the label. In addition, the
label should contain the following wording:
Where tree height and/or canopy density is reduced, the dose (and water volume) should be adjusted in
accordance with an appropriate dose adjustment scheme. Consult your specialist advisor for further
information. Further information on the PACE scheme is available from AHDB Apple Best Practice
Guide, or PACE website
3.3
Information on the occurrence or possible occurrence of the development of
resistance (KCP 6.3)
Please refer to the core assessment Part B, Section 3.
For those targets considered to be a high resistance risk in the UK, and for which a resistance management strategy is required, applicants are expected to consider, and where necessary adapt, the proposed
strategy in the core dossier to UK conditions. As part of this consideration should be given to pest
pressures, and relevance of the GAP (including number of applications as part of the required season
long treatment programme). There is a range of available information, starting with the UK Resistance
Action Groups (RAGs), which give information on current resistance issues, as well as publish various
specific guidance, see:

In addition, CRD have produced specific guidance for each product type, within which is information
on UK specific label wording and, in some cases, statutory restrictions on the conditions of use. These
restrictions are based around limiting the number of applications for a specific mode of action (MOA)
group on particular targets, for example neonicotinoid insecticides, azole fungicides, and ACCase/ALS
inhibitor herbicides.

Adverse effects on treated crops (KCP 6.4)
3.4.1
Phytotoxicity to host crop (KCP 6.4.1)
Please refer to the core assessment Part B, Section 3.
It is anticipated that this should in most cases be satisfactorily addressed in the core assessment. In
certain circumstances specific UK data may be or at least further justification may be required for key
commercial varieties. This is where it is important to ensure a broad range of varieties have been tested, to make a case that this would be relevant to UK specific varieties.
Again, extrapolation can be based on EPPO extrapolation tables, in conjunction with EPPO1/257 ‘Efficacy and crop safety extrapolations for minor uses’.
3.4.2
Effect on the yield of treated plants or plant product (KCP 6.4.2)
Please refer to the core assessment Part B, Section 3.
It is anticipated this will be addressed in the core assessment, unless a specific UK crop is requested.

Effects on the quality of plants or plant products (KCP 6.4.3)
Please refer to the core assessment Part B, Section 3.
Apples and Pears
The principle UK commercial varieties remain ‘Cox’ and ‘Bramley’ (apple), and ‘Conference’ (pear).
All these varieties are prone to russetting, and there have been historical cases of pesticides increasing
these effects. It is important therefore that this aspect of crop quality is satisfactorily addressed for
these UK varieties. Applicants may be able to refer to an appropriate range of tested varieties in the
core zonal package. To do so, the UK national addendum should cross-reference to the appropriate
part of the core dossier, and highlight those varieties tested that are also sensitive to russetting. Alternatively, specific data should be provided on the above named UK varieties. Where sufficient data/evidence of safety to the major UK varieties is not provided a label warning “Crop safety on
‘Cox’/‘Bramley’’/Conference has not been established’ may be required.
Taint
For certain crop/product type uses, it is necessary to consider the possibility of taint. Full details on
when and how to address these issues are available in EPPO standard 242(1) ‘Taint tests’. It is expected that this aspect is covered in the core assessment, unless there are relevant crops specifically
requested for the UK.
Where taint has not been addressed for the relevant crops, the UK label will carry the warning as described in 1/242(1), listing the specific crops where taint has not been addressed:
‘CONSULT PROCESSOR BEFORE USING ON [listed crops] FOR PROCESSING.’
3.4.4
Effects on transformation processes (KCP 6.4.4)
Please refer to the core assessment Part B, Section 3.
For certain crop/product type uses, it is necessary to consider the potential impact on (biological) transformation processes. Full details on when and how to address these issues are available in EPPO
standard 1/243 (1) ‘Effects of plant protection products on transformation processes. It is expected
that this aspect is covered in the core assessment, unless there are relevant crops specifically requested
for the UK.
3.4.5
Impact on treated plants or plant products to be used for propagation (KCP
6.4.5)
Please refer to the core assessment Part B, Section 3.
It is not anticipated that a UK National addenda would be required for this point, unless exceptionally a
UK specific crop was considered (and where EPPO 1/135 requires further testing).

Observations on other undesirable or unintended side-effects (KCP 6.5)
3.5.1
Impact on succeeding crops (KCP 6.5.1)
Please refer to the core assessment Part B, Section 3.
Herbicides: Succeeding Crops, and ALS Sequences
A detailed risk assessment covering succeeding crops (rotational and re-planting/crop failure) will have
been included in the core zonal assessment. The core assessment should have covered an appropriate
range of crops, and more than one typical crop rotation scenario (encompassing the worst case situation).
However, the applicant may need to consider further, and if necessary, adapt as appropriate to UK conditions. In particular, are the sensitive indicator crop species and crop rotation scenarios (including
planting intervals) relevant to the UK? For example, maize is not common in a UK crop rotation. Has
the predominance of autumn sowing in the UK been covered in the core risk assessment? The applicant may need to consider further the need for specific UK risk mitigation and label warnings.
In addition to the above, the applicant must address the specific issue of the use of sequences or mixtures of acetolactate synthase (ALS) inhibiting herbicides. Such herbicides have been identified in the
past as presenting a particular risk to succeeding crops when used under UK conditions and UK labels
typically prohibit mixtures or sequences of herbicides containing ALS inhibitors. It is possible to remove this restriction, by submission of appropriate data. Applicants should refer to Efficacy Guideline
303 for full details.
(This restriction is distinct from those in place on resistance grounds as outlined in Efficacy Guideline 611).
3.5.2
Impact on other plants including adjacent crops (KCP 6.5.2)
Please refer to the core assessment Part B, Section 3.
It is not anticipated that a UK National addenda would be required for this point.
3.5.3
Effects on beneficial and other non-target organisms (KCP 6.5.3)
Detailed studies on the potential adverse effects to beneficial organisms are summarised in part B, Section
9 Ecotoxicology.
Further specific data, beyond the core zonal assessment, is only required if specific positive claims are
proposed on UK labels regarding compatibility of the product with Integrated Pest management.
Claims such as ‘IPM compatible’ are generally discouraged because such a broad based statement is
difficult to support without an extensive data package (unless an argument can be made based on the
mode of action e.g. a biopesticide). Instead claims relating to specific beneficial species (usually commercial species used in certain crops) are more easily supported by data, for example safe reintroduction periods or highlighting temporary adverse effects. Such claims can be supported in part
by reference to relevant ecotoxicology data. However, further data would be required under more real-

istic conditions to consider e.g. effects of predators eating treated prey, effects of contact with pesticide
residues on plants (either direct lethal affects or on fecundity).
In situations where biological control is commonly practised (e.g. top fruit, glasshouse crops), if no
information is provided on IPM compatibility, a label warning will be added:
‘Safety to beneficial organisms used in IPM systems has not been established and cannot be assumed’.
3.6
Other/special studies
a) Molluscicide pellets
The UK has specific requirements for molluscicide pellets, based on their long term use in the UK and
high slug pressures, related to quality aspects of the pellet to ensure there is not a significant breakdown
of pellet during application; or for the duration of control. There is also specific standardised methodology where UK labels include claims over the properties of pellet in relation to periods of rainfall.
Whilst these are requirement for the UK, with full details in Efficacy guideline 510, the methodologies
are also recommended in EPPO 1/95(4) ‘Slugs’

Observe palatability and pellet integrity over the course of the effectiveness trial.

Evidence of satisfactory flow and retention of pellet/seed integrity during application through
representative commercial machinery is required. The applicant can argue on the relevance of
the commercial machinery used in this assessment.
Molluscicides also have specific requirements if the product label makes specific statement on
the ‘shower proof’ or ‘rain proof’ properties of the pellets, these must be supported by data.

Please also note there are specific labelling requirements for molluscicide amateur products (Regulatory Update 03/2010(2)2).
b) Seed treatments
It should be noted that claims of activity against unnamed seed/soil-borne pests are generally not allowed. In addition, UK labelling policy is to have only one recommended dose, which is based on the
major pest target (and on which dose justification is based).
All seed treatments must be labelled with the following precautionary general statement:
‘Sowing treated seed that has been stored for prolonged periods (beyond the season of treatment) may
adversely affect effectiveness and/or crop safety’
This does not preclude companies from choosing to support a specific label claim concerning the period of time treated seed may be stored before sowing. In such instances, data should be generated with
the storage period in any studies reflecting the length of time proposed on the label. These data follow
the requirements for seed treatments when not stored and are fully described under the relevant chemistry sections of the data requirements.
The data should cover the satisfactory retention of the chemical and physical properties of the seed

treatment product in its container, and demonstrating satisfactory loading of the product on the
seed when treatment is made by commercial seed treatment machinery.
The suggested minimum retention of active ingredient(s) is 70 % of the initial target dose, and this
is the level that would be usually expected after the claimed storage period. Alternatively, a case
for satisfactory retention of active ingredient(s) may be made based on the biological effectiveness
of the product. For example, effectiveness trials using treated seed that has been stored for the
relevant time period before sowing.
Seed drill tests – Please note that for all treated seed (and pelleted formulations), evidence must
be provided to demonstrate the satisfactory flow of treated seed through the relevant seed drill
mechanism(s) available commercially.
Comparison should be made with untreated and standard treated seed from the same batch.
c) Convenience tank mixtures
A convenience tank mix is the combination, by the user, of two or more pesticides in the same spray
tank to reduce the number of spray operations.
No efficacy data are required to support applications for convenience tank-mixes. Evidence of physical
and chemical compatibility continues to be required in line with EU guidance. (See Regulatory Update
22/2014 ‘Tank mixtures of plant protection products – Updated UK Requirements for full details).
NOTE – this does not change the requirements for positive recommendations (with other pesticides or
adjuvants), which still require supporting efficacy data; or for ALS herbicides (see Efficacy Guideline
303: Effects on Non-Target Crops of Highly Active Herbicides – including Mixtures and Sequences’;
or anticholinesterase products.
d) Formulation changes
EU Guidance SANCO 12638 provides broad principles on changes in chemical composition of a formulation. However, it has little specific advice on what constitutes either major or minor changes (for
which efficacy data may/may not be required), and takes a more precautionary approach to changes in
content. EPPO are currently developing guidance to address Efficacy aspects, particularly in relation to
changes in surfactant systems.
In the interim, the UK criteria for formulation changes can be applied to UK-only proposed formulation
changes, where the proposed change is not already addressed in the EU document. Applicants should
refer to Efficacy Guideline ‘UK Guidance on Plant Protection Products formulation changes.
