New con­trols on some OP in­sec­ti­cides – a re­minder

The En­vi­ron­men­tal Pro­tec­tion Author­ity (EPA) and the Min­istry for Pri­mary In­dus­tries (MPI) have re­assessed a num­ber of Organophos­phate and Car­ba­mate (OPC) in­sec­ti­cides.

Ta­ble 1 pro­vides a sum­mary of the new con­trols, MRLs (max­i­mum residue lev­els) and PHIs (pre-har­vest in­ter­vals) that are now in force as a re­sult of the re­assess­ments.


A num­ber of in­sec­ti­cides will be phased out in the near fu­ture.

• Pho­r­ate (Crop Care Pho­r­ate 20 G, Thimet 20G) was banned on 1 July 2016 and can no longer be used.

• Ox­amyl (Vy­date) is no longer reg­is­tered.

• Proth­io­fos (Tokuthion), Fe­namiphos (Ne­matak; Nemacur; Fe­nafos, Canyon), Methami­dophos (Metafort, Methafos) and Ter­bu­fos (Counter 20G) will be banned by 1 July 2023 (in 7 years).

• Di­azi­non will be banned by 1 July 2028 (in 11 years).


Most OPC in­sec­ti­cides have ad­di­tional con­trols. New la­bels (those printed from July 2015) should be read care­fully. All grow­ers must ad­here to all la­bel in­struc­tions as for some prod­ucts (in Ta­ble 1), the di­rec­tions are all manda­tory. These ad­di­tional con­trols came into ef­fect on 1 July 2015, and in­clude:

• Bee con­trols – when you can and can­not spray. The main con­trol is around not ap­ply­ing if bees are present or are likely to be present or are for­ag­ing dur­ing ap­pli­ca­tion un­til af­ter the spray has dried. In ad­di­tion some prod­ucts can­not be ap­plied 7 to 10 days pre-flow­er­ing, with ex­clu­sions for some crops (re­fer to in­di­vid­ual la­bels for in­struc­tions).

• Re-en­try in­ter­vals and non-con­tact pe­ri­ods ap­ply – most are at least 12 to 48 hours.

• Max­i­mum rate and num­ber of applications – these dif­fer and can be per sea­son or per crop cy­cle. Some also have set ap­pli­ca­tion in­ter­vals.

• Re­strict­ing method of ap­pli­ca­tion – i.e. no ap­pli­ca­tion to sen­si­tive ar­eas, no aerial ap­pli­ca­tion, only us­ing fully au­to­mated equip­ment, only spot or dip­ping, hand-gun use banned etc.

• No­ti­fi­ca­tion of neigh­bours and dis­play­ing of sig­nage is a re­quire­ment for al­most all OPCs.

• Spray drift mit­i­ga­tion mea­sures are re­quired for most OPCs where the ap­pli­ca­tor must not cause ad­verse

ef­fects be­yond the bound­ary of the treated prop­erty, and must avoid ad­verse ef­fects from spray drift.

• Other con­trols – such a cover gran­ules with soil and keep records of use are also new.

• New MRLs and PHIs have been set for some crops. This is sum­marised in Ta­ble 1.

All of the ad­di­tional con­trols have been sum­marised in the past and can be sent to you upon re­quest. Please con­tact your busi­ness man­ager.

The new use pat­terns and con­trols are on prod­uct la­bels ap­proved af­ter July 2015 and can be viewed on the MPI web­site here: https://eat­safe.nzfsa.­is­ter.


The eight com­pounds be­low were re­assessed, with the ad­di­tional six com­pounds in Ta­ble 1 also re­assessed by MPI (in ad­di­tion to the EPA). The con­trols sum­marised are ap­pli­ca­ble to all of these com­pounds. The re­assess­ments re­sulted in use pat­terns be­ing re­vised and some crops be­ing re­moved from la­bels. You can no longer use Acephate (Orthene), Di­azi­non (Dew), Fe­namiphos (Nemacure) and Methami­dophos (Metafort, Methafos) off la­bel. You must only use these prod­ucts strictly ac­cord­ing to la­bel di­rec­tions and must ob­serve all con­trols. This in­cludes fol­low­ing ex­act use pat­tern di­rec­tions i.e. us­ing these prod­ucts strictly ac­cord­ing to the la­bel claims in terms of ap­proved crops, max­i­mum rates, ap­pli­ca­tion fre­quen­cies, tim­ing, with­hold­ing pe­ri­ods (WHPs), tar­get in­sects etc. This in­for­ma­tion is sum­marised in Ta­ble 1. >
