SECTOR ASSESSMENT FEEDBACK FORM
Organophosphate and carbamate use in kiwifruit
production
Introduction
In this assessment the EPA has documented what it understands is the current state of the kiwifruit
industry in New Zealand (your sector), based on publicly available information and feedback from the
sector. When complete, this sector assessment will form part of the EPA’s formal application for
reassessment of organophosphate and carbamate insecticides.
To help complete the assessment, we need your input.
This document contains:
 A profile of your sector
 Some information on your sector’s use of organophosphates and carbamates and alternatives you
may use
 A preliminary assessment of the risks
 Possible options for managing risks
We acknowledge this document is not complete. Where there are gaps in our data please
include information to help us fully understand the current situation. We have put some
specific questions in grey boxes throughout the document for you to answer.
We need you to:
 Correct inaccuracies and provide us with additional information about your sector by editing this
document using “tracked changes” or printing the document out and writing onto it.
 Change or add information about yield, sales values, employment figures, major pests, and
insecticide use patterns, in the tables that we have started to populate.
 Answer the questions about your research, pest management programmes, proposed controls,
and the impacts the loss of organophosphates and carbamates would have on your sector.
 Suggest additional or alternative management options (controls) that would be practical and
effective.

Approach to pest management
Pest management systems
It is important to understand how the sector manages insecticide use.
1. Describe the management systems you have in place to regulate insecticide use.
Comment on any sector-wide programmes or private standards used by growers, and
estimate what percentage of your sector follows these practices. Please reference or
attach your sources.
Since 1997, kiwifruit grown for export has been grown organically or in accordance with an IPM
programme called KiwiGreen®, resulting in a reduction in insecticide use4.
The Crop Protection Programme (CPP) is based on KiwiGreen®, an Integrated Pest Management (IPM)
programme, developed in the early to mid-1990’s specifically for the kiwifruit industry. The CPP takes into
account targeted spraying across a range of pest species using softer chemicals or cultural practices to
maintain control of the key pests3. ZESPRI indicates that the reliance on organophosphates in the CPP
has been progressively reduced.
To be accepted for export, all kiwifruit must be grown in accordance with the CPP
Organophosphate and carbamate use
We are interested in the pests for which organophosphate and/or carbamate use is critical to your
sector. Table 4 lists the active ingredients registered for use in your sector, as well as other uses you
have told us about. Please indicate which of these active ingredients you are and are not using, and
add rows to include information for other organophosphates and carbamates that are being used but
are not captured in the table.
Do you use any organophosphates/carbamates on your crop post harvest? If so, please add
this information into Table 4 below, and provide use information by updating Table 6.
We also need you to tell us for which pests the use of organophosphates and carbamates is critical,
and which are able to be managed using alternatives.

Organic pest management techniques for kiwifruit pests include the following6:
Scale:
 Control of scale depends on how much there was last year. If there was a high loading or if the
fruit was rejected for scale then the approach is altered. This would involve waterblasting the
trunks, followed by a handgun mineral oil application on trunks and leaders, with a pre-blossom oil
spray as well. Scale numbers are monitored. With correct nutrition, and if the vines are healthy,
then less scale is found. E.g. in pre-drought conditions down to one oil-spray, but post-drought
waterblasting required.
 Treatment of surrounding areas to control scale is not necessary – they provide a friendly habitat
for birds, including welcome swallows, fantails. Small birds also help keep insect populations in
check, however the nests of larger birds are removed.
Bird deterrence:
 Some growers have issues with birds. Techniques to keep birds off vines include the laying of
roadkill, which attracts hawks and keeps birds off the vines. Also the shelterbelt used makes a
difference: thin cover such as pittosporum tends to attract (pest) birds, while stouter cover, such as
banksias, are useful as they attract tuis.
Leafroller
 2 post blossom sprays of Bt (Bacillus thuringiensis) are used – these are generally sprayed in late
afternoon as the bacteria in BT is sensitive to sunlight, and leafroller tend to feed at dusk and dawn
(late afternoon tends to extend the lifespan into the following days). Clean water, not chlorinated is
used. Most orchards require two sprays. Clusters are then monitored. This is generally found to be
effective and re-spray is generally not needed.
2. What is the basis of your choice of active ingredients to manage your critical pests?
Be specific about the efficacy and cost differences between options.
The kiwifruit industry has identified diazinon as, until recently, a key insecticide for the control of armoured
scale on kiwifruit 5. In a 2004 crop-based diazinon use estimate, the kiwifruit sector used a total of 29.66
tonnes a.i./year7. Due to an MRL reduction in the EU, diazinon was removed from the ZESPRI CPP.
Diazinon can no longer be used on kiwifruit vines but can be used on shelterbelts, which are a host for
armoured scale. Several alternatives are identified 5.
The kiwifruit industry support the continued availability of OPs, submitting that with the removal of broad
spectrum chemicals in the last few seasons the general ‘contaminant’ pest population has gradually
increased. The effective control options for mites, thrips and some mealybug species has diminished
May 2012

APP201045 Kiwifruit Sector Assessment
meaning an increasing incidence of a number of pests is found at harvest.
3. Tell us about pest control research undertaken by your sector, and any trials
underway or completed that would reduce your reliance on organophosphates and
carbamates. This could include a description of cultural or chemical control methods
that have been tried in the past and met with mixed success, or that are being
investigated currently. If you have identified alternatives please give us a timeline for
when they will be available for use (Reference or attach sources).
Example: Collectively New Zealand growers spend $x each year on research of which $y is spent
researching pest control. Currently projects are underway to establish the potential for...
4. List pests that are likely to pose a future threat to your sector, and comment on what is being
used to combat them elsewhere. This could include existing and potential pests.
Although the kiwifruit sector is not a high volume user of OPs it does support the continued availability for
other sectors to ensure there is continuity of supply to New Zealand if a strategic use is needed by the
sector in the future.
With regard to biosecurity use: although OP options would be highly desirable during the incursion phase,
availability of broad spectrum control options for growers after the incursion has wound down will also be
desirable3.
Modelling risks on current use
Table 6 summarises our understanding of your sector’s use patterns for organophosphates and
carbamates. These use patterns are the basis for our preliminary risk assessment. Use patterns were
drawn from label statements as well as from industry feedback.
The EPA has only assessed the risks for the use patterns it has information about. Uses will
be restricted to those described in Table 6 unless we receive further information.

APP201045 Kiwifruit Sector Assessment
If your use patterns are different to those shown in Table 6, please amend the table. Please indicate
which rows are incorrect or not relevant to your sector. If rows in Table 6 are incomplete, please
complete them. If you have use patterns not covered by any of the rows in the table, please add extra
rows to describe the additional use pattern.
You have indicated that your use of organophosphates and carbamates is reducing. Are there any of
these substances that you would want to retain the option to use? If so, include these substances in
Table 6 and indicate at what rate you would use them.

Risks
Overview
The EPA has evaluated the risks to operators, re-entry workers, bystanders, the aquatic environment,
birds and bees from using these substances. All risk assessment results in this document should be
considered preliminary as they may change with additional feedback. The final risk assessment
results will be presented in the reassessment application.
Results are described as risk quotients (RQs) which compare predicted exposures and maximum
concentrations that will not cause adverse effects. All risk quotients have been normalised so that
RQs above 1 exceed the EPA’s Level of Concern where effects are likely to be seen.
Data gaps
Fenamiphos is registered for used on kiwifruit against Root Knot nematode. There are significant data
gaps that affect our understanding of the risks that fenamiphos pose to both human health and the
environment. Our risk assessment for fenamiphos could be refined if additional data about its dermal
absorption was provided. In the absence of information the EPA has assumed that 50% of the
fenamiphos in both the product and the spray would be absorbed through skin.
5. Please provide information about the dermal absorption of fenamiphos, and reference or
attach your sources.
The EPA could not find any information about the toxicity of fenamiphos to bees. Given its status as
an insecticide, the EPA is assuming that fenamiphos will pose a high risk to bees.

Risk modelling
This section summarises our understanding of the risks of organophosphates and carbamates based
on modelling of the risks to human health and the environment.
Figures 1 and 2 show the maximum and minimum risk quotients for your sector’s use of each active
ingredient. Both figures depict risks assuming that operators wear full PPE (chemical resistant gloves,
coveralls, sturdy footwear, a hood and visor), that re-entry workers do not enter the crop for 24 hours
after spraying and that Good Agricultural Practice is followed.

Quantitative estimates of risk to operators, re-entry workers, bystanders, the aquatic environment,
birds and bees have been made for all use scenarios except for dipping roots (fenamiphos) for which
risks to re-entry workers, bystanders and environmental risks are assumed to be negligible.
Maximum RQ values across your sector’s range of use scenarios are shown in Figure 1. These are
worst-case scenarios generally indicating high application rates and frequency. If the maximum RQ is
less than one, no additional risk management is needed, but if the RQ is greater than one, risk
management will be needed for at least some uses.
The minimum RQs depicted in Figure 2 indicate the best-case scenarios across your sector’s use of
these substances i.e. the lowest rates and safest formulations. Substances for which the minimum
RQ is greater than one for one or more endpoints require risk management.
Information and assumptions used for modelling risks can be found in the accompanying Background
Document.
Possible risk management options
It is possible that additional controls could help to manage the risks posed by organophosphates and
carbamates. The EPA has evaluated some possible controls to help reduce risks for each of the usescenarios. This could mean that for some substances uses with low risks would be retained while
others may require additional risk management.
Possible risk management options are listed in Table 7. Appendix A describes the possible options in
more detail and defines terms used in Table 7. .Existing controls will continue to apply to a
substance..

APP201045 Kiwifruit Sector Assessment
The risk management options in Table 7 are based on an assessment of the substances’ risks alone. Data you provide on actual use patterns, alternative
risk information and additional controls will help us to re-evaluate this risk assessment.
We know that many of these substances have significant benefits, and the final decision on their future use will consider their risks, costs and benefits.
However, if the benefits are not shown to outweigh the risks phase out may be triggered for some uses.
May 2012

APP201045 Kiwifruit Sector Assessment
What is the impact?
We need your input about the practicality of the possible risk management options and, if these
controls are impractical, we are asking you to suggest alternatives to manage the risks.
When answering the questions below please consider what the impact on your sector would be if the
options above were applied. Please supply information to support your assessment.
6. Which of the possible risk management options in Table 7 would be workable if they
were implemented in your sector? Please describe how you could make them work in
the field.
Example: We always apply downwind buffer zones when applying these substances. Or: Wearing
respirators during application could reduce risks in a similar way to closed cab application, and is a
cheaper option for us.
7. If you think that any of the possible risk management options in Table 7 are not
workable please explain why.
Example: The maximum application rate is too low to control XYZ insect populations. Or: We often need
to re-enter fields during the summer within the first 24 hours to apply irrigation.
Be specific
In the questions below we are asking you to indicate what economic impact the possible risk
management options would have e.g. how a lower application rate would affect your costs or, if the
controls are unworkable, what effect the phase out of a substance would have.
Much of the feedback that we have received to date has included generalisations such as, “without
organophosphates our crop would be decimated”, and localised facts like, “without organophosphates
my farm would lose $70,000 per year”. This feedback is useful to give us an idea of the nature and
extent of the problem, but we need more information to help us understand the effect of the changes
on your sector.
Please include the type of information provided in the example below when responding to questions 7
to 10.
May 2012

APP201045 Kiwifruit Sector Assessment
Hypothetical example
If our industry were not able to use diazinon then we estimate that the cost of control would increase
by $200/hectare on an average annual basis. Approximately 80% of the kiwifruit growing area would
be affected, mainly in the North Island (75% affected in Bay of Plenty). As well as the additional cost
of control we believe that the production levels would reduce by 10% and this would mean that there
would be less work for pickers and packers, and the total export value would decrease by 15%. This
would be a long term effect (probably 10 years) while alternative products were developed and
registered for use.
8. How would the loss of any of the substances in Table 7 affect you? We are particularly
interested in those substances that are critical to the profitable production of your crop.
Please provide information separately for each substance.
9. How would the possible risk management options affect your production costs?
10. Please describe how employment in your industry would be affected if the risk
management options were implemented and if high risk uses of some substances
were phased out. If possible indicate changes to on-farm and off-farm employment
separately.
11. How would the possible options affect production/yield, and your income or the value
of your sector? Include information for the possible loss of high risk uses requiring
the substitution of alternatives. Please quote average per annum figures and show
your workings.
May 2012
19
APP201045 Kiwifruit Sector Assessment
12. Comment on how any impacts would change with time. Would the impact on yield
and value of implementing the possible risk management options be short term or
long term, and would the effects increase or decrease over time?
Example: If application rates were reduced we would see little difference in yield short term, but over time
pest pressure would increase along with costs. Yield and value may reduce in the mid-term until effective
alternatives were available.
Alternative options to manage risks
In Table 7 we have outlined a range of possible options for managing the risks of organophosphate
and carbamate use on kiwifruit. We are interested in any alternative measures to manage these risks
which may be more appropriate. You may have existing obligations under product stewardship or
good agricultural practice schemes that you think address the concerns that we have identified. Less
toxic alternatives may have been identified which the sector is planning to adopt. It may also be
possible to reduce the levels of exposure through use of specific technology like recapturing
application equipment which applies less substance within a treatment area. There may also be
alternative management strategies that you might use.
13. Please suggest other control measures to reduce the risks of using organophosphates and
carbamates. Provide us with specific details which will enable us to evaluate the impact of
your proposals. For example include details of reduced exposure that would be achieved by
lowering application rates to a specified amount, reducing applications to an identified
number, or using recapture technology. Explain what mix of management techniques and/or
alternative substances you would prefer to use. Make sure that you explain which
substances the controls would apply to, and if they are stand-alone measures or
implemented as a suite of controls.

Appendix A
Tables 8 and 9 provide explanations of the possible options and definitions of the terms used.
Table 8: Descriptions of possible options for reducing risks
Description
A restriction on the permitted application methods is applied so that the
substance may only be applied using [application method]. This
requirement must be stated on the label.
Application equipment
Buffer Zone
In circumstances where a particular application method poses high risks,
a restriction may be imposed to prohibit that use. Alternatively, in order
to retain a particular use pattern (such as a critical use), use of a specific
application method may be specified.
Application of the substance is only permitted in conjunction with a buffer
zone as described in NZS 8409:2004 The Management of
Agrichemicals, which is available from Standards New Zealand
(www.standards.co.nz or call 0800 STANDARDS). This requirement
must be stated on the label.
A Buffer Zone is the minimum separation distance downwind of an area
where a substance is applied and a sensitive area.
Application of the substance is only permitted using a vehicle equipped
with a fully enclosed closed operator cab, where the cab air intake is
fitted with chemical filters. This requirement must be stated on the label.
Closed cab application
A reduction in the exposure of a person applying a substance can be
achieved by using application equipment where the operator is within a
fully enclosed cab, fitted with chemical filters to ensure that the airsupply for the operator is not contaminated with chemicals.
The substance must be loaded into the application equipment using a
closed system. This requirement must be stated on the label.
Closed loading systems
Granule application restriction
Closed mixing and loading systems can be used in order to remove the
exposure to operators during this phase of the substance lifecycle.
Liquids may be charged to the spray tank using closed pumping systems
in a spray shed, or by charging mechanisms on the sprayer. For
granules used in aqueous sprays, water soluble packaging can be used.
The substance must be applied below the surface of the soil, or be
covered completely with soil immediately after application. This
requirement must be stated on the label.
This restriction will put an obligation on the applicator to ensure that the
substance does not pose a post application risk to birds.
A maximum application rate is set for this substance. This requirement
must be stated on the label.
Maximum application rates
May 2012
The risk assessment for a given substance has been carried out for
particular use parameters. Use of a substance in excess of the
quantities assessed can give rise to greater levels of risk, and as a
23
APP201045 Kiwifruit Sector Assessment
result, the proposed controls may not adequately manage the risks
posed.
This substance must not contain more than 1.5%(w/w) with a particle
size of less than 150 µm.
Minimisation of dust or fine
particles
This condition is to ensure that fine particles or dust are excluded from
the substance, so that handling of the substance does not result in
exposure to dust or fine particles.
In the case of an organophosphate-containing substance, the main label
must clearly identify the substance as containing an organophosphate
chemical; or
Chemical class identification
In the case of a carbamate-containing substance, the main label must
clearly identify the substance as containing a carbamate chemical.
This additional labelling condition will provide clear identification of the
chemical class of the substance, and is to ensure that the end-user is
aware of the type of substance being handled.
Personal Protective Equipment
(PPE)
Respiratory Protective
Equipment (RPE)
Use of specific RPE is prescribed. This requirement must be stated on
the label.
The additional requirement for RPE details the specific minimum
requirements for RPE and are in addition to the requirement for use of
full PPE when handling the substance or entering a treated area within a
REI.
After [date], use of this substance on [crop/sector] is no longer permitted.
Phase-out Period
For substances that have use patterns that are to be phased out, a
period of time is established to provide an opportunity for use or disposal
of the substance. After the Phase-out Period has elapsed, use of that
substance will no longer be permitted for that particular use pattern. For
substances that are used in different sectors, such a restriction may be
imposed for certain uses or application methods in certain sectors, whilst
being retained in others.
Entry into treated areas is not permitted until the Restricted Entry
Interval has elapsed since the end of application of the substance,
unless PPE (and RPE where prescribed for operators) is worn for the
time that the person is within the treated area. This requirement must be
stated on the label.
Restricted Entry Interval (REI)
May 2012
A Restricted Entry Interval (REI) is the period of time which must elapse
after application of a substance before entry into the treated area is
permitted without use of PPE and RPE (as required). Entry into a treated
area before the REI has elapsed is only permitted if full PPE is worn
(and RPE if required for application of the substance). Additionally, the
entry restriction may limit the tasks that may be carried out within the
treated area, and the time per day that a person may spend in the
treated area within the REI.

Table 9: Definitions of terms used in the possible options
Description
Implementation Period
It is appropriate to allow a period of time in order to implement any
changes of controls applied to a substance. If an Implementation Period
is specified, then the controls that currently apply to a substance are
valid until the end of the implementation period. Once the
Implementation Period has elapsed, any new controls, or changes to the
existing controls, must be followed.
PPE is protective equipment that is specifically designed to prevent nonrespiratory exposure of a person handling chemicals.
Full PPE constitutes the following clothing and equipment:
Personal Protective Equipment
(PPE)
Respiratory Protective
Equipment (RPE)
 Chemical resistant gloves;
 Coveralls;
 Sturdy footwear;
 A hood and visor.
RPE is protective equipment that is specifically designed to prevent
exposure of the respiratory system to chemicals, such as using a
respirator fitted with an appropriate chemical filter.
A sensitive area is a location that may be sensitive to drift of an applied
substance. Sensitive areas include:
 Residential buildings and areas;
Sensitive area (definition)
 Private property;
 Places where public may lawfully be (e.g. schools, parks,
playgrounds, day care facilities, prisons, hospitals, nursing homes);
 Waterways.
Waterway (definition)
May 2012
A waterway includes modified water courses such as reservoirs,
irrigation canals, water supply races, canals for supply of water for
electricity generation or farm drainage canals, as well as natural water
bodies.
