Ministry for Primary Industries   Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  • 3 2 Introduction  
Maximum residue l evels (MRLs) are the maximum legal levels  for residues of agricultural 
compounds and veterinary medicines in food for sale in New Zealand. MRLs are primarily a 
tool for monitoring the use of agricultural compounds in accordance with good agricultural 
practice (GAP). GAP i s not explicitly defined or regulated, but is the generally accepted 
means for producing safe primary produce in a particular location while taking account of 
climate, pests or diseases and other environmental factors. MRLs are used to minimise risks 
to pu blic health by ensuring that chemical residues in food are as low as practicable, without 
compromising the ability of the chemical to successfully do what is intended.  
2.1 BACKGROUND  
MRLs are set out in the New Zealand (Maximum Residue Levels for Agricultural 
Compounds) Food Notice. The MRL Food Notice is  amended a number of times each year 
to reflect changes in the use of agricultural compounds in the production of food. The MRL 
Food Notice is  available from the Ministry for Primary Industries (MPI) Food S afety website 
at: http://mpi.govt.nz/document -vault/11329 .  
 
MPI administers the MRL Food Notice , with the final decision on any changes to the Notice  
resting with the  Director -General  of MPI.  The Food Notice is issued under sections 405 and 
406(1) of the Food Act 2014. When setting or amending MRLs, the Director -General mu st 
take into account:  
• the need to protect public health;  
• the desirability of avoiding unnecessary restrictions on trade;  
• the desirability of maintaining consistency between New Zealand's food standards 
and those applying internationally;  
• New Zealand's obligations under any relevant international treaty, agreement, 
convention, or protocol, and, in particular, under the Australia- New Zealand Joint 
Food Standards Agreement; and 
• such other matters as appropriate.  
 
Once the amended MRL Food Notice is in place, official chemical residue monitoring 
programmes are reviewed and are amended as necessary.  
 
Possible implications for public health are considered during the toxicological and dietary risk 
assessments, by comparing the estimated dietary intake with a Health Based Guidance 
Value (HBGV). This may be either a Potential Daily Exposure (food) (PDE (food)) or an 
Acceptable Daily Intake (ADI). The ADI and PDE (food) are largely equivalent, as they are 
determined using the same set of toxicology data and through a very similar scientific 
process.  
  
A PDE (food) is a value determined by a toxicological evaluation by the Environmental 
Protect ion Authority (EPA) as part of its responsibility for managing public health under the 
Hazardous Substances and New Organisms Act 1996 (the HSNO Act).  A PDE (food) gives the 
potential daily exposure a person may be subject to from a substance, via food. MP I uses a 
PDE (food) where it is available, rather than the internationally -determined ADI, as required by 
the HSNO Act in New Zealand.  
 
An ADI is defined by the World Health Organization (WHO) as: “the daily intake which, during an entire lifetime, appears to be without appreciable risk on the basis of all the known facts at 
the time”. “Without appreciable risk” has been further defined as : “the practical certainty that 
injury will not result even after a lifetime of exposure”. ADIs are established by the WHO and 
Food and Agriculture Organization (FAO) of the United Nations joint expert committees, 
which are made up of toxicologists and res idue specialists. The ADI information from these 
joint committees also feeds into the Codex Alimentarius Commission (Codex), which sets  
4 • Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  Ministry for Primary Industries  international MRLs.  An ADI may also occasionally be set in New Zealand by the EPA. Where 
an EPA-determined or an internationally -determined ADI is not available, an ADI may be 
calculated by MPI to quantify  the dietary exposure risk.  
 
MPI uses the PDE (food) set by the EPA as the HBGV for the estimation of dietary intake when 
they are available. Where there is no PDE (food), the estimated dietary intake is compared with 
the ADI, set by the EPA, the WHO/FAO joint expert committees, or the European Food 
Safety Authority (EFSA). If none of these are available, the HBGV used will be the MPI -
determined ADI.   
 
The chronic dietary exposure to a substance is estimated by the National Estimated Dietary 
Intake (NEDI) calculation, encompassing all registered uses of the chemical and food 
consumption data based upon the 1997 National Nutritional Survey for adults and the 1995 
National Nut rition Survey of Australia, for children. The NEDI calculation is made in 
accordance with Guidelines for predicting dietary intake of pesticide residues (revised) 
[World Health Organization, 1997]. The NEDI calculation provides an estimation of the 
portion of the  PDE (food) or ADI that can be expected from consumption of food containing 
residues complying with existing and proposed MRLs to determine whether the chronic 
dietary exposure risk is acceptable  
Clause 144 of the Food Regulations 2015 states that imported food must contain residues of 
agricultural compounds no greater than the MRLs specified for that food in a notice set under 
the Food Act 2014 (section (1)(a)), the default MRL of 0.1 mg/kg (section (1)(c)), or the 
current editions of either the Maximum Residue Limits (MRLs) and Extraneous Maximum  
Residue Limits (EMRLs) for Pesticides (Codex Pesticides Residues in Food Online 
Database), or the Maximum Residue Limits for Veterinary Drugs in Food (Codex Veterinary Drug Residue in Food Online Database)  (section (1)(d)).  
 The “other  international MRLs ” listed in each entry is a summary of the MRLs set by Codex 
and other internationally regulatory bodies. For animal commodities, MRLs set by our major 
trading partners (Australia, Canada, China, Codex, the European Union, Japan, and the 
United States) are reviewed and compared; for horticultural commodities, only MRLs set by 
Codex and Australia are reviewed and compared unless there is a particular trade reason to 
include other regions . Where a particular in ternational body or regulator does not have MRLs 
set for the species or crop for which a New Zealand MRL is being proposed, that 
international body or regulator is omitted from the “other international MRLs” section of the 
entry.  
  
To meet New Zealand’s obligations under the Agreement on the Application of Sanitary and 
Phytosanitary Measures the proposed MRL will be notified to the World Trade Organization. 
Any country may choose to comment if they believe the proposed MRL represents a barrier 
to their trad e. 
 
2.2 SUMMARY OF PROPOSED AMENDMENT  
The proposed MRLs have been thoroughly assessed in accordance with international 
methodologies such as those utilised by the expert committees advising Codex. Information 
on the technical assessment of each proposal is inc luded in this document (refer section 3) 
and covers:  
 
• rationale;  
• chemical information;  
• good agricultural practice;  
• residues information;  
• dietary risk assessment;  
• toxicological/public health assessment; and  
• MRLs set by Codex and other countries .

MPI reviewed the estimated dietary exposure assessments for the application of the 
proposals in this discussion paper and compared them with the appropriate HBGV  (the 
PDE (food) or the ADI). MPI has determined that the residues associated with the proposed 
MRLs do not present any public health or food safety concerns.

8 • Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  Ministry for Primary Industries   
3.1.1 Amendment Rationale  
In 2016 , the residue definition for abamectin  was amended in Australia to omit the reference 
to the (Z) -8,9 isomers of avermectin B1a and B1b. This was based on a lack of significant 
residues of the 8,9- Z isomers, and the lack of any quantifiable residues of toxicological 
significance associated with them . This approach has also been taken by Codex , the EU, 
and many of New Zealand’s major trading partners, who have set  residue definitions based 
on avermectin  B1a alone, the  sum of avermectin B1a and B1b, or the sum of B1a, B1b, and 
the delta 8,9 isomer.  It is noted that Japan is the only major trading partner that has retained 
the 8,9- Z isomers in their residue definition.  
In New Zealand, there has been  a lack of detectable residues for the 8,9- Z isomers . With a 
lack of any detections, and a lack of any toxicologically significant residues associated with 
these i somers, it is considered that there is  no need to continue to include them in the New 
Zealand residue definition.   
All currently established MRL  values  for this compound will remain unchanged.   
3.1.2 Chemical Information  
Common name of compound  Abamectin  
Use of compound  Pesti cide 
Chemical Abstract Services (CAS) Registry number  71751 -42-2  
Type of compound  Avermectin  
Administration method  Topical, oral, and parenteral  (animal) ;  
Spray (plant)  
3.1.3 Good Agricultural Practice  
Abamectin  is used as an insecticide on a number of horticultural crops, and as an endo - and 
ectoparasiticide in production animals. The current use patterns, withholding periods, and 
MRLs are still considered appropriate to support GAP and will not change.  
3.1.4 Residue Information 
The residue dat a for the approved crops  and target animal species  support the current 
MRLs, and demonstrate consistently low levels of total abamectin residues , as well as 
demonstrating that levels of the 8,9- Z isomers are below the limit of detection.  In addition, in 
most test methodologies the small amount of 8,9- Z isomers that are present are captured in 
the assay of avermectin B1a and do not warrant a separate identifier in the residue definition. 
It is therefore considered that the residue data sup ports the change in the residue definition.

3.2.1 Amendment Rationale  
The proposed MRLs are representative of the outcomes of the organophosphate and 
carbamate (OPC) reass essment as they pertain to acephate. The new MRLs will allow for 
the continued use of the compound in compliance with GAP , and the restrictions applied to 
use and ex posure a t the completion of the New Zealand Environmental Protection Authority 
(EPA) ’s reassessment.

3.2.3 Good Agricultural Practice  
Acephate is used as an insecticide on avocados, citrus fruits, cabbages, cauliflowers, lettuce, 
tamarillos, tomatoes , and boysenberries for the control of a range of insect pests . As a result 
of the OPC reassessment, label claims for potatoes and tomatoes grown indoors have been 
removed, and the withholding periods for lettuce and outdoor tomatoes  have been changed 
from 3 days to 14 days.   
The MRL for ‘any other food’ will ensure compliance with the restriction to on -label uses only, 
and will support GAP.  
3.2.4 Residue Information 
With the changes to the approved crops and withholding periods, the  residue data for the 
retained crops support the MRLs as proposed. The new MRL s have been  proposed to 
support GAP.  
3.2.5 Dietary Risk Assessment  
The Health Based Guidance Value (HBGV)  of 0.0012 mg /kg bw/d was considered 
appropr iate for use in the assessment .  
The active ingredient methamidaphos  is the primary  metabolite of acephate. The dietary risk 
assessment incorporated exposure to both acephate and methamidaphos  to ensure 
exposure was accurately represented  in the associated crops . Based on the residues 
expected in food from crops treated according to existing and proposed GAP uses, the NEDI 
for acephate as ‘acephate and methamidaphos ’ is equivalent to  less than 93% of the HBGV . 
It is therefore concluded that the risk associated with  chronic dietary exposure is acceptable.   
Ministry for Primary Industries   Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  • 11 3.2.6 Toxicological/Public Health Assessment

3.3.1 Amendment Rationale  
The proposed MRL for honey is the outcome of a review of the residue profile of amitraz 
when used according to what is considered GAP in New Zealand. The proposed MRL will 
manage  the residues in honey following the use of amitraz in bee hives in accordance with 
use rates and withholding periods  established as  GAP  in New Zealand.  
There is no data to suggest that  the current MRL for ‘other bee products’ is in sufficient to  
continue to manage residues in those products. As such, the current MRL of  1 mg/kg will be 
retained.

3.3.3 Good Agricultural Practice  
Amitraz is used as an acaricide for the treatment and control of infestations of the mite 
Varroa destructor  on honey bees. A maximum of two s trips impregnated with 33g/kg amitraz 
each are suspended in the brood chamber for sustained- release of the compound in the 
spring,  before the first honey flow , for a maximum of six weeks. In cases where infestation is 
severe, a second treatment period can be initiated in the autumn after honey has been 
removed from the hive. Strips are not to be used during honey production.  
3.3.4 Residue Information 
The new residue data provided supports an amitraz  MRL of 0.2  mg/kg in honey when the 
compound is used on honey bees . The MRL is proposed to support GAP.  
3.3.5 Dietary Risk Assessment  
The HBGV  of 0.01  mg/kg bw/d was considered appropriate for use in the assessment . 
Based on the residues expected in food from crops treated according to existing and proposed GAP uses, the NEDI for amitraz  is equivale nt to less than 17% of the HBGV . It is 
therefore concluded that the risk associated with chronic dietary exposure is small and can 
be considered acceptable.

3.4.3 Good Agricultural Practice  
Benzovindiflupyr  is use d as a preventative fungicide in wheat at a maximum of two 
applications of 75  gai/ha, in combination with another approved fungicide with a different 
mode of action . The compound is used for the prevention of glume blotch, leaf rust, speckled 
leaf blotch, and stripe rust in wheat, and is applied not after GS69 (end of flowering). Use of 
benzovindiflupyr attracts withholding periods of 42 days for wheat grain and 28 d ays for 
wheat forage ( green feed) .   
3.4.4 Residue Information 
The residue data supports a MRL of 0.0 5 mg/kg for benzovindiflupyr  in wheat  grain. Animal 
transfer residue data supports the following MRLs in animal commodities: 0.01 mg/kg in 
mammalian meat, 0.01 m g/kg in mammalian fat, 0.01 mg/kg, 0.01 mg/kg in edible offal of 
mammals except liver, 0.03 mg/kg in cattle, sheep, horse and goat liver, 0.01 mg/kg in pig 
liver, 0.01 mg/kg in meat, fats,  eggs  and edible offal of poultry, and 0.01 mg/kg in milk. The 
MRL s are proposed to support GAP  in New Zealand.  
3.4.5 Dietary Risk Assessment  
The HBGV  of 0.035 mg/kg bw/d was considered appropriate for use in the assessment.  
Based on the residues expected in food from crops treated according to p roposed GAP uses  
and in commodities from animals that have been exposed during consumption of treated 
crops , the NEDI for benzovindiflupyr  is equivalent to less than 2 % of the  HBGV . It is

It is noted that the proposed New Zealand MRLs for liver are higher than those set by Codex. However, when used in accordance with New Zealand GAP, liver residues are expected to 
exceed the 0.01 mg/kg Codex MRL but remain below 0.03 mg/kg in all species except pigs. 
Although alignment with Codex would be ideal, in this case the Codex MRL would be too low 
to support GAP in New Zealand.

Clopidol is use d in the prevention of coccidiosis caused by certain Eimeria species in broiler 
chickens at a continuous feeding rate of 125 grams clopidol per tonne finished feed. A 
withdrawal period of two days  applies  to this use.  
3.5.4 Residue Information 
The residue data provided to support the use of clopidol in broiler chickens supports the 
proposed MRLs of 0.5 mg/kg in chicken  meat , fat and kidney,  and 1 mg/kg in chicken  liver. 
These MRLs are proposed to support GAP.   
3.5.5 Dietary Risk Assessment  
The HBGV of 0.007 mg/kg bw/d  was considered appropriate for use in the assessment.  
Based on the residues expected in food from animals treated according to proposed GAP 
uses, the NEDI for c lopidol  is equivalent to less than 13% of the HBGV . It is therefore 
concluded that the risk associated with chronic dietary exposure is small and can be 
considered acceptable.  
3.5.6 Toxicological/Public Health Assessment  
It has been determined that the use of clopidol in broiler chickens,  in accordance with the

Derquantel used proposed for the treatment and control of gastrointestinal parasites, 
lungworm, nasal bot and itch mites in sheep, at a dose rate of 2 mg derquantel/kg body 
weight. The dose rate  and withholding periods currently applicable to the use of derquantel in 
sheep remain unch anged , and are considered GAP . 
3.8.4 Residue Information 
The residue data on file for derquantel supports MRLs  of 0.007 mg/kg in sheep fat, 0.0008 
mg/kg in sheep liver, 0.0004 mg/kg in sheep kidney, and 0.0003 mg/kg in sheep meat at the 
withholding period currently applied to the product containing derquantel. As such, the MRLs 
are proposed to support GAP as well as align with Codex limits.   
The existing withholding periods applied to the registered products containing derquantel are 
considered sufficient to manage residues at the proposed MRLs, and will remain unchanged.  
3.8.5 Dietary Risk Assessment  
The HBGV  of 0.005 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from animals treated according to existing and

Chemical Abstract Services (CAS) Registry number  333-41-5 
Type of compound  Organophosphate  
Administration method  Spray  
3.9.3 Good Agricultural Practice 
Diazinon  is used as an insecticide on certain fruits, vegetables, and cereal grains  for the 
control of a range of insect pests, and as an ectoparasiticide in sheep. As a result of the OPC 
reassessment, label claims for a number of horticultural crops have been removed,  requiring 
the entry to be revised to specify those crops for which approval is being retained. The 
withholding periods for some of the remaining crops have also been amended.   
The sheep kidney and liver MRLs, proposed to align with Codex and overseas trading 
partners, will support the GAP use of diazinon in that species.  
The MRL for ‘any other f ruit, vegetable or nut ’ will ensure compliance with the restriction to 
on-label uses only, and will support  the GAP  use of diazinon in crops .  
3.9.4 Residue Information 
With the changes to the approved crops and withholding periods,  residue data for the 
retained crops  and animal uses  support the MRLs as proposed. The new MRLs have been  
proposed to support GAP.  
3.9.5 Dietary Risk Assessment  
The HBGV  of 0.0002 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops  and animals  treated according to the 
uses now proposed as GAP , the NEDI  for diazinon  is equivalent to less than 94% of the 
HBGV . It is t herefore concluded that the risk associated with chronic dietary exposure is 
acceptable.  
3.9.6 Toxicological/Public Health Assessment  
It has been determined that the use of diazinon as an insecticide on food crops , and as an 
ectoparasiticide for use on sheep , when applied according to GAP, is very unlikely to pose 
any health risks from consumption of treated produce.

Ministry for Primary Industries   Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  • 25 3.11.2.2 Residue Information 
The residue data for use in broiler chickens  supports MRL s for diclazuril o f 1 mg/kg in 
chicken fat, 2 mg/kg in chicken kidney, 3 mg/kg in chicken liver, and 0.5  mg/kg in chicken 
muscle. The MRL s are proposed to support GAP.  
3.11.2.3 Dietary Risk Assessment  
The HBGV  of 0.015 mg/kg bw/d was considered appropriate for use in the assessment . 
Based on the residues expected in food from animals  treated according to existing and 
proposed GAP uses, the NEDI  for diclazuril is equivalent to less than 2 0% of the HBGV . It is 
therefore concluded that the risk associated with chronic dietary exposure is minimal  and can 
be considered acceptable.  
3.11.2.4 Toxicological/Public Health Assessment

An MRL  was previously proposed for fenpyrazamine at 0.05 mg/kg to support the use pattern 
considered GAP for grapes in New Zealand. In response to a submission from one trading 
partner, requesting consideration of a higher MRL that reflects their GAP for grapes,  the New 
Zealand MRL has been reconsidered in order to facilitate trade.  It is considered that the new

Fenpyrazamine is proposed for use on wine grapes for the treatment of grey mould ( Botrytis 
cinerea)  at up  to 2 foliar sprays of 40 gai/100L, applied to full coverage up to full bunch 
closure. This  use is considered GAP  in New Zealand as part of a season- long control 
programme. The applicable withholding period is use up to pre- bunch closure but not less 
than 65 days before harvest.   
28 • Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  Ministry for Primary Industries  It is noted that overseas, fenpyrazamine is used later in the season for fungicidal control, and 
GAP includes application at early bloom, pre- bunch closure, or veraison. This had led to the 
need for a higher MRL than would be appli ed if use was limited to that considered GAP in 
New Zealand.   
3.13.4 Residue Information 
The residue data support s an MRL for fenpyrazamine in grapes of  3 mg/kg. This MRL is 
proposed to facilitate trade .  
3.13.5 Dietary Risk Assessment  
The HBGV  of 0.091 mg/kg bw/d was considered appropriate for use in the assessment.  
Based on the proposed MRL, the NEDI for fenpyrazamine is equivalent to less than 0.2% of 
the HBGV . It is therefore concluded that the risk associated with chronic dietary exposure is 
small and can be consi dered acceptable.

3.16.1 Amendment Rationale  
The amendment  represents the approval of an additional use for fluazinam . The proposed 
MRL will manage the use of fluazinam when used on onions in acc ordance with the 
application  rates and withholding periods that are proposed as GAP in New Zealand.

Use of compound  Fungicide  
Chemical Abstract Services (CAS) Registry number  79622 -59-6 
Type of compound  Pyridine  
Administration method  Spray  
3.16.3 Good Agricultural Practice  
Fluazinam  is used as a fungicide on  grapes, tomatoes, potatoes, brassica vegetables, and 
now onions. The new use in onions requires a  foliar  application rate of 400gai/ha between 
bulb formation and pre- harvest, with a maximum of two applications per season,  for the 
control of Botrytis (neck rot). This use attracts a 14 day withholding period in onions.  
3.16.4 Residue Information 
The residue data for t he crop  supports  a fluazinam  MRL of 0.02 mg/kg on onions . This MRL  
is proposed to support GAP.  
3.16.5 Dietary Risk Assessment  
The HBGV  of 0.004  mg/kg bw/d  was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops treated according to existing and 
proposed GAP uses, the NEDI  for fluazinam  is equivalent to less than 51% of the HBGV . It is  
32 • Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  Ministry for Primary Industries  therefore concluded that the risk associated with chronic dietary exposure is considered 
acceptable.  
3.16.6 Toxicological/Public Health Assessment

3.17.1 Amendment Rationale  
The proposed new crop MRLs represent the expansion of use for fluopyram . The proposed 
MRLs will manage the use of fluopyram  as a fungicidal seed treatment in cereal s, and for  
Ministry for Primary Industries   Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  • 33 control of nematodes  in carrots. These uses are in accordance  with the application rates that 
are proposed as GAP in New Zealand.  
The new and amended animal MRLs are being proposed to align with those set in the EU 
and Japan. The proposed revised MRLs will be compliant  with those set by Codex in animal 
commodities.

Use of compound  Fungicide  and Nematicide  
Chemical Abstract Services (CAS) Registry number  658066 -35-4 
Type of compound  Pyridylethylamide  
Administration method  Spray  
3.17.3 Good Agricultural Practice  
Fluopyram  is proposed for use as a fungicidal seed treatment for control of seed-  and soil -
borne diseases in barley, oats, triticale, and wheat at a rate of 10 gai/tonne of seed as a 
single treatment. Because this treatment is only used on seeds that will be supplied for the 
planting of crops and will not be used for human or animal consumption, no withholding 
period applies to this use.  
Fluopyram is also proposed for use as a nematicide in carrots for the control of root knot 
nematode at a rate of 500 gai/ha in 200L of water/ha as a single application . The withholding 
period applied to this use is 100 days in carrots, with a restriction t hat fluopyram must not be 
used on carrots that will be harvested less than 100 days from planting (e.g. baby carrots).  
3.17.4 Residue Information 
The residue data for the crops supports a MRL s at 0.01  mg/kg for  cereal crops  and 0.2 
mg/kg in carrots . These MRL s are proposed to support GAP.   
The residue data evaluating the potential for transfer of residues to animals fed treated crops supports the amendment of the existing animal commodity MRLs and the addition of poultry MRLs. Although these amendments are being proposed more for trade purposes, the new 
MRLs are still considered to support GAP.  
3.17.5 Dietary Risk Assessment  
The HBGV  of 0.008 4 mg/kg bw/d was considered appropriate for use in the assessment.  
Based on the residues expected in food from crops treated according to existing and proposed GAP uses, the NEDI  for fluopyram  is equivalent to less than 39% of the HBGV . It is 
therefore concluded that the risk associated with chronic dietary exposure is considered 
acceptable.   
3.17.6 Toxicological/Public Health Assessment  
It has been determined that the use of fluopyram as a fungicide for cereal crop seeds  and as 
a nematicide on carrots,  when treated according to GAP, is very unlikely to pose any health 
risks from consumption of treated produce.

The new MRL is proposed to support  a new use for fluxapyroxad on onions  in accordance 
with the application rates and withholding periods  that are proposed as  GAP in New Zealand.  
Although the new use is specific to bulb onions, the proposed MRL will cover the use of 
fluxapyroxad on onions and accommodate the presence of residues in bulb vegetables 
planted in rotation with treated onions.

3.18.2.1 Good Agricultural Practice  
The proposed use of fluxapyroxad is to control is to control white rot in onions  by applying 
210 gai/ha at 2 -3 week intervals, either as a block of  two consecutive sprays or in a 
programme alternating fluxapyroxad and a fungicide with a different mode of action. This use 
attracts a withholding period of 21 days from the last application.  
3.18.2.2 Residue Information 
The residue data for  onions  and other bulb vegetables  supports a fluxapyroxad MRL of 0.2 
mg/kg. This MRL is proposed to support GAP.  
3.18.2.3  Dietary Risk Assessment  
The HBGV  of 0.0 14 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops treated according to existing and 
proposed GAP uses, the NEDI for  fluxapyroxad is equi valent to less than 5% of the HBGV . It 
is therefore concluded that the risk associated with chronic dietary exposure is small and can 
be considered acceptable.  
3.18.2.4  Toxicological/Public Health Assessment  
It has been determined that the use of  fluxapyroxad in onions , according to the GAP 
specified above, is very unlikely to pose any health risks from consumption of treated or exposed produce .

or two treatments (the first between GS13 and GS29, and the second before GS39) at a rate 
of 5 gai/ha ; it is not to be applied after GS39. The livestock  withholding period applicable to 
this use is seven days (for fodder or green feed).  
3.19.1.4  Residue Information  
The residue data supports MRLs of 0.01 mg/kg for halauxifen- methyl  in all three 
commodities . The M RLs are proposed to support GAP.   
3.19.1.5  Dietary Risk Assessment  
The HBGV  of 0.0406  mg/kg bw/d was considered appropriate for use in the assessment.   
Based on the residues expected in food from crops treated according to the proposed GAP

3.20.1 MRL Promulgation  Rationale  
The proposed MRLs represent the registration of a product containing ipconazole  for use on 
cereals (barley, oats, triticale and wheat) and sweetcorn.  The proposed MRLs will manage 
the use of ipconazole, in association with one other active ingredient as a fungicidal seed 
treatment in accordance  with the application rates that are proposed as GAP in New 
Zealand.

Use of compound  Fungicide  
Chemical Abstract Services (CAS) Registry number  125225 -28-7 
Type of compound  Triazole  
Administration method  Spray  
3.20.3 Good Agricultural Practice 
Ipconazole  is proposed for use as a fungicidal seed treatment for control of seed-  and soil -
borne diseases in barley, oats, triticale, and wheat, as well as sweetcorn, at a rate of 80 
gai/tonne of seed as a single treatment. Because this treatment  is only used on seeds that 
will be supplied for the planting of crops and will not be used for human or animal 
consumption, no withholding period applies to this use.   
3.20.4 Residue Information 
The residue data supports MRLs of 0.01 mg/kg for ipconazole in all of the associated 
commodities . The M RLs are proposed to support GAP .  
3.20.5 Dietary Risk Assessment  
The HBGV  of 0.01 05 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from seeds  treated according to the proposed GAP 
uses, the NEDI  for ipconazole is equivalent to less than 1% of the HBGV . It is therefore 
concluded that the risk associated with chronic dietary exposure is small and can be 
considered acceptable.  
3.20.6 Toxicological/Public Health Assessment  
It has been determined that the a pplication of ipconazole to cereal and sweetcorn seeds  for 
the management of seed - and soil -borne diseases , when used according to GAP, is unlikely 
to pose health risks from consumption of treated produce.

3.21.1 Amendment Rationale  
The proposed MRLs represent the outcomes of the OPC  reassessment as they  pertain to 
maldison. The new MRLs will allow for the continued use of the compound in compliance 
with GAP and the restrictions applied to use and exposure at the completion of the EPA 
reassessment.

Use of compound  Insecticide  
Chemical Abstract Services (CAS) Registry number  121-75-5 
Type of compound  Organophosphate  
Administration method  Spray  
3.21.3 Good Agricultural Practice  
Maldison is used as an insecticide on a number of horticultural and agricultural crops for the 
control of a range of insect pests . As a result of the reassessment, the number of 
applications per crop have been reduced to two per season and the majority of the 
withhold ing periods were extended to adjust the estimated dietary intake. Withholding 
periods for grapes, p ipfruit, stonefruit, avocados, citrus fruits, vegetables, and pasture have 
all been extended to 7 days; withholding periods for sweetcorn and cereals have al so been 
extended , to 14 days.  
The MRLs for cattle fat, horse fat, pig fat and eggs have been retained as previously promulgated. The new MRLs for ‘meat, fat or offal from any other animal’ and ‘milk’ , 
previously captured in the ‘any other food’ MRL,  will remain at 0.5 mg/kg to ensure residues 
are appropriately managed in any other grazing species.  
3.21.4 Residue Information 
With the changes to the approved crops and withholding periods, the  residue data for the 
retained crops support the MRLs as proposed. These M RLs are proposed to support GAP.  
3.21.5 Dietary Risk Assessment  
The HBGV  of 0.02 mg /kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops treated according to existing and 
proposed GAP uses  and animal exposure to treated crops , the NEDI for maldison is 
equivalent to less than 76% of the HBGV . It is therefore concluded that the risk associated 
with chronic dietary exposure is acceptable.  
3.21.6 Toxicological/Public Health Assessment  
It has been determined that the use of maldison on the crops listed above,  according to the 
GAP specified above, is unlikely to pose any health risks from consumption of treated 
produce.

white rot and downy mildew in bulb onions. The compound will be used at a rate of 375 
gai/ha in 500L/ha of water on beans as a preventative treatment from early flowering with 
one repeat treatment 7- 10 days later. In bulb onions, it will be used at a rate of 300 gai/ha in 
500-1000L water/ha as a preventative treatment  at 100 -150 growing degree days (GDD) with 
one repeat treatment one month later. The withholding periods applicable to these uses are 
30 days for onions and 7 days for beans. To manage the potential for residues in livestock, a 
statement applies that animals are not be grazed on treated bean crops or fed crop trash.   
3.22.4 Residue Information 
The residue data supports an MRL of 0. 7 mg/kg in  beans, including the pods, and 0.01 
mg/kg in bulb onions.  These MRLs are  proposed to support GAP. With the ‘do not graze 
treated bean crops or feed crop trash to livestock’ statement in place, it is considered that 
animal commodity MRLs are not required.   
3.22.5 Dietary Risk Assessment  
The HBGV  of 0.133 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops treated according to the proposed GAP 
use, the NEDI  for mandestrobin  is equivalent to less than 1 % of the  HBGV . It is therefore 
concluded that the risk associated with chronic dietary exposure is small and can be 
considered acceptable.  
3.22.6 Toxicological/ Public Health Assessment  
It has been determined that the use of mandestrobin as a fungicide  on beans and bulb 
onions , when used according to GAP , is very unlikely to pose any health risks from 
consumption of treated produce.  
3.22.7 Other International MRLs  
There have been no MRLs set by either Codex or Australia for the use of mandestrobin on 
beans and bulb onions.

3.23.1.1  Amendment Rationale  
The new MRL is proposed to support  a new use for metalaxyl for  use on cereals (barley, 
oats, triticale and wheat) and sweetcorn.  The proposed MRLs will manage the use of 
metalaxyl , in association with one other active ingredient as a fungicidal s eed treatment in

3.23.3 Good Agricultural Practice  
Metalaxyl  is proposed for use as a fungicidal seed treatment for control of seed-  and soil -
borne di seases in barley, oats,  triticale, and wheat, as well as sweetcorn,  at a rate of 64  
gai/tonne of seed as a single treatment. Because this treatment is only used on seeds that 
will be supplied for the planting of crops and will not be used for human or animal 
consumption, no withholding period applies to this use.    
Ministry for Primary Industries   Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  • 43 3.23.4 Residue Information 
The residue data supports MRLs of 0.01 mg/kg for metalaxyl  in all of the associated crops. 
The M RLs are proposed to support GAP . Based on the residue data in animals, it was 
determined that animal commodity MRLs are not required.  
3.23.5 Dietary Risk Assessment  
The HBGV  of 0.024 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from seeds  treated according to the proposed GAP 
uses, the NEDI  for metalaxyl  is equivalent to less than 1 0% of the HBGV . It is therefore  
concluded that the risk associated with chronic dietary exposure is small and can be 
considered acceptable.  
3.23.6 Toxicological/Public Health Assessment  
It has been determined that the a pplication of  metalaxyl  to cereal and sweetcorn seeds  for

3.24.1 Amendment Rationale  
The proposed MRLs represent the outcomes of the OPC reass essment as they pertain to 
methamidophos . The new MRLs will allow for the continued use of the compound in 
compliance with GAP, and the restrictions applied to use and exposure at  the completion of 
the EPA’s reassessment.

3.24.3 Good Agricultural Practice  
Methamidophos  is used an insecticide on certain fruits and vegetables for the control of pest 
insects. It is also a metabolite of acephate (see 3.2 above).  
As a result of the OPC reassessment, label claims for snap beans and indoor tomatoes have 
been removed, and the use of the active has been restricted to on- label uses only. This has 
required the MRL entry for methamidaphos to be revised to specify those cr ops for which 
approval is being retained for methamidaphos -containing products, and to ensure 
appropriate levels are established for those crops that may contain methamidaphos residues 
as a result of acephate breakdown. The MRL for ‘any other food’ will ensure compliance with 
the restriction to on- label uses only, and will support GAP.    
3.24.4  Residue Information  
With the changes to the approved crops and withholding periods,  residue data for the 
retained crops  support the MRLs as proposed. The new MRLs have bee n proposed to 
support GAP.  
3.24.5 Dietary Risk Assessment  
The HBGV  of 0.000 1 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops  and animals  treated according to the 
uses now proposed as GAP , the NEDI  for methamidophos  is equivalent to less than 69% of  
Ministry for Primary Industries   Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  • 45 the HBGV . It is therefore concluded that the risk associated with chroni c dietary exposure is  
acceptable.  
3.24.6 Toxicological/Public Health Assessment  
It has been determined that the use of methamidophos  as an insecticide on food crops , when 
applied according to GAP, is very unlikely to pose any health risks from consumption of 
treated produce.

3.25.4 Residue Information 
The residue data supports an MRL of 0. 01 mg/kg for metrafenone in grapes . The M RL is 
proposed to support GAP . The potential for residues in animals grazing in vineyards will be 
appropriately managed with the on- label 6 month livestock withholding period;  it is 
considered that animal commodity MRLs are not required.  
3.25.5 Dietary Risk Assessment  
The HBGV  of 0.18 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops  treated according to the proposed GAP

cattle w ill attract a meat withholding period of 5 days  and milk withholding period of 35 days.    
3.26.4 Residue Information 
The residue data for the target species cattle supports monepantel  MRLs of 7 mg /kg for 
cattle  fat, 1 mg/kg for cattle kidney , 2 mg/kg for cattle  liver,  0.3 mg/kg for cattle meat, and 
0.05 mg/kg for cattle milk . These MRLs are proposed to support GAP.   
3.26.5 Dietary Risk Assessment  
The HBGV  of 0.02 mg/kg bw/d was considered appropriate f or use in the assessm ent.  
Based on the residues expected in food from animals treated according to existing and 
proposed GAP uses, the NEDI  for monepantel  is equivalent to less than 1 2% of the HBGV . It 
is therefore concluded that the risk associated with chronic dietary exposure is small and can 
be considered acceptable.  
3.26.6 Toxicological/Public Health Assessment  
It has been determined that the administration of monepantel  to cattle  for the treatment of

(*) indicates that the maximum residue limit has been set at or about the limit of analytical quantification.  
3.27.1.1  Amendment Rationale  
The new MRL for cereal grains other than barley grain is an outcome of the change in the 
residue definition for prothioconazole promulgated in the last Notice amendment. The 
previous residue definition was “sum of prothioconazole and its desthio metabolite”, two 
metabolites, whereas the amended definition is for only one meta bolite, prothioconazole-
desthio. As such, the permissible residue level in cereal grains (except barley grain) is 
proposed to be reduced to 0.01 mg/kg to reflect the limit of quantific ation of the desthio 
metabolite.  
There are no changes in the use patterns or GAP of the product associated with this 
amendment.

3.28.3 Good Agricultural Practice  
Pyrimethanil is used as a fungicide on grapes  pome fruits, and now onions. The new use in 
onions requires a foliar application rate of 640 gai/ha between bulb formation and pre-
harvest, with a maximum of two applications per season, for the control of Botrytis (neck rot). 
This use attracts a 14 day withholding period in onions.  
3.28.4 Residue Information 
The residue data supports an MRL of 0. 02 mg/kg for pyrimethanil  in onions, and t he M RL is 
proposed to support GAP .  
3.28.5 Dietary Risk Assessment  
The HBGV  of 0.12 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops  treated according to the proposed GAP 
uses, the NEDI  for pyrimethanil  is equivalent to less than 3 % of the HBGV . It is therefore 
concluded that the risk associated with chronic dietary exposure is small and can be 
considered acceptable.

3.29.1 MRL Promulgation  Rationale  
The proposed MRLs represent the registration of a product containing pyroxsulam for use on  
cereals . The proposed MRLs will manage the use of pyroxsulam  as a herbicide in 
accor dance with the application rates and withholding periods that are proposed as GAP in

3.29.3 Good Agricultural Practice  
Pyroxsulam is used as a selective herbicide for the control of broadleaf weeds in cereal 
crops . The compound is used as a single treatment between GS13 and GS39, or two 
treatments (the first between GS13 and GS29, and the second before GS39) at a rate of 5 gai/ha; it is not to be applied after GS39. The livestock withholding period applicable to this 
use is seven days (for fodder or green feed).  
3.29.4 Residue Information 
The residue data supports the promulgation of MRL s of 0.01 mg/kg in all crops being treated 
and animal commodities that may be exposed to treated crops.  These MRLs are proposed to 
suppor t GAP.    
3.29.5 Dietary Risk Assessment  
The HBGV  of 0.7 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops treated according to the proposed GAP use and in commodities from animals that have been exposed to treated crops , the NEDI  for 
pyroxsulam  is equivalent to less than 1 % of the  HBGV . It is therefore concluded that the risk 
associated with chronic dietary exposure is small and can be considered acceptable.   
52 • Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  Ministry for Primary Industries  3.29.6 Toxicological/Public Health Assessment  
It has been determined that the use of pyroxsulam  as a herbicide on cereal crops , when 
used according to GAP , is very unlikely to pose any health risks from consumption of treated

3.30.1.1  Amendment Rationale  
The new MRLs in animal commodities are proposed to support  a new use for sulfoxaflor  on 
forage brassicas.  The revised MRLs are proposed to allow for the use of sulfoxaflor in forage 
brassicas  in accordance  with the application rate that is proposed a s GAP in New Zealand, 
and subsequent feeding of livestock . MRLs are not required for the forage brassicas 
themselves as they are not produced for human consumption.  
3.30.2 Chemical Information  
Common name of compound  Sulfoxaflor  
Use of compound  Insecticide  
Chemical Abstract Services (CAS) Registry number  946578 -00-3 
Type of compound  Sulfoximines  
Administration method  Spray  
3.30.3 Good Agricultural Practice  
Sulfoxaflor  is used as an insecticide on wheat, barley, vegetable crops, and  now forage 
brassicas . The new use in forage brassicas requires an application rate of 2 4gai/ha when 
pest populations exceed threshold levels, with a maximum of two applications per season .  
Existing livestock- specific withholding periods for sulfoxaflor include restricting grazing of 
wheat and barley fodder or green feed for 28 days from the last application . The withhol ding 
periods attracted by the new forage brassica use include a restriction to not cut, feed or 
graze treated crops until 14 days after the last application for animals intended for meat 
production, and for 28 days after applicat ion for animals intended for milk production.  
3.30.4 Residue Information 
The residue data supports sulfoxaflor MRL s of 0.07 mg/kg  in mammalian meat, 0.04 mg/kg 
in mammalian fat, 0.2 mg/kg in mammalian liver, 0.1 mg/kg in mammalian kidney, and 0.03 mg/kg in milk. These MRLs are proposed to support GAP .  
3.30.5 Dietary Risk Assessment  
The HBGV of 0.028 mg/kg bw/d was considered appropriate f or use in the assessment .   
54 • Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  Ministry for Primary Industries  Based on the residues expected in food from crops  treated according to the proposed GAP 
uses, and in commodities from animals that have been exposed to treated crops , the NEDI  
for sulfoxaflor  is equivalent to less than 10 % of the HBGV . It is therefore concluded that the 
risk associated with chronic dietary exposure is small and can be considered acceptable.  
3.30.6 Toxicological/Public Health Assessment  
It has been determined that the a pplication of sulfoxaflor on forage brassicas  as an 
insecticide , when used according to GAP, is unlikely to pose health risks from consumption 
of treated produce and animals exposed to treated crops .

It is noted that the Codex MRL for milk is lower than that proposed for New Zealand. 
Although alignment with codex would be ideal, in this case the Codex MRL would be too low 
to support GAP in New Zealand.  
3.31 PROPOSAL TO AMEND MRLS FOR TAU- FLUVALINATE  
It is proposed that MRLs  for tau -fluvalinate are amended to support the GAP use of the 
compound on potatoes.

Ministry for Primary Industries   Proposed Amendment  to the Maximum Residue Levels for  Agricultural Compounds Food Notice 2016  • 55 3.31.1.1  Amendment Rationale  
The new MRL is proposed to support  a new use for tau -fluvalinate on potatoes.  The 
proposed MRL will manage the use of tau -fluvalinate in  accordance  with the application rate 
that is proposed as GAP in New Zealand.  
3.31.2 Chemical Information

Use of compound  Insecticide  
Chemical Abstract Services (CAS) Registry number  102851 -06-9 
Type of compound  Synthetic pyrethroid  
Administration method  Spray  
3.31.3 Good Agricultural Practice  
Tau-fluvalinate  is used as a n insecticide  on fruit, vegetable, and cereal crops,  and now 
potato c rops.  The new use in potatoes , for management of aphids and psylla,  requires an 
application rate of 180gai/ha in 200- 500 litres of water with a maximum of 3 applications at 7-
14 day intervals at the first sign of pest presence before rotating to another in secticide. The 
use of tau -fluvalinate in potatoes attracts a 7 day withholding period.  
3.31.4 Residue Information 
The residue data support s a MRL of 0. 01 mg/kg  in potatoes . This MRL is  proposed to 
support GAP .  
3.31.5 Dietary Risk Assessment  
The HBGV of 0.005 mg/kg bw/d was considered appropriate for use in the assessment .  
Based on the residues expected in food from crops  treated according to the proposed GAP 
uses, the NEDI  for tau-fluvalinate is equivalent to less than 2 0% of the  HBGV . It is therefore 
concluded that the risk associated with chronic dietary exposure is minimal  and can be 
considered acceptable.  
3.31.6 Toxicological/Public Health Assessment  
It has been determined that the a pplication of tau-fluvalinate  on potatoes  as an insecticid e, 
when used according to GAP, is unlikely to pose health risks from consumption of treated 
produce .  
3.31.7 Other International MRLs  
There have been no MRLs set by either Codex or Australia for the use of tau- fluvalinate on 
potatoes.
