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

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.
