Proposals to Amend the New Zealand (Maximum Residue Limits of Agricultural Compounds) Food Standards 2008
6 Proposal to set MRLs for Methomyl
It is proposed that an MRL is set for methomyl when used as an insecticide for berries and fruiting vegetables (except cucurbits). It is proposed that Schedule One of the NZ (MRL) Food Standards 2008 be amended by deleting the following MRL:
Compound |
CAS# |
Residue definition |
Food |
Maximum Residue Limit (mg/kg) |
Methomyl |
16752-77-5 |
Sum of: Methomyl Thiodicarb Expressed as: Methomyl |
Berries and other small fruits Fruiting vegetables (except cucurbits) |
0.3 0.3 |
As a replacement for the deleted MRLs, it is proposed that Schedule One of the NZ (MRL) Food Standards 2008 be amended to include the following:
Compound |
CAS# |
Residue definition |
Food |
Maximum Residue Limit (mg/kg) |
Methomyl |
16752-77-5 |
Sum of: Methomyl Thiodicarb Expressed as: Methomyl |
Berries and other small fruits Fruiting vegetables (except cucurbits) |
0.5 0.5 |
The final entry for methomyl in Schedule One of the NZ (MRL) Food Standards 2008 will therefore read:
Compound |
CAS# |
Residue definition |
Food |
Maximum Residue Limit (mg/kg) |
Methomyl |
16752-77-5 |
Sum of: Methomyl Thiodicarb Expressed as: Methomyl |
Beans Berries and other small fruits Brassica vegetables Cereal grains Fruitng vegetables (cucurbits) Fruiting vegetables (except cucurbits) Lettuce Pome fruits |
0.2 0.5 0.2 0.2 0.2 0.5 0.2 1 |
Amendment Rationale
The proposed MRLs represent an administrative correction to the MRL standard. It was noted that an error had occurred whilst the standard was in transition from its previous format to the current version, this error being that the entries for methomyl in berries and fruiting vegetables had dropped from 0.5mg/kg to 0.3mg/kg in 2005. The GAP for the use of methomyl has not changed and there remains the potential that its use could leave residues upto 0.5mg/kg. As such reinstating the correct entries is necessary to correctly regulate the GAP.
