Maleic Hydrazide re-approved by EU but…

Wednesday, 28 November 2018

The European Union (EU) has renewed the approval of the plant growth regulator Maleic Hydrazide (MH), however new regulatory requirements will now apply to all products containing MH.

MH products are used on potatoes for sprout suppression and volunteer control. In accordance with EU regulations, MH products are now required to contain lower levels of hydrazine in order to meet tightening restrictions on metabolites.

More significantly, under the new EU regulation (2017/1506) crops treated using MH products can no longer be fed to livestock.

The UK approval body the Chemicals Regulation Directorate (CRD) requires that all crop protection products containing MH must now carry on the label the phrase ‘Do not feed to livestock’

These restrictions apply to all MH products from the authorisation holders from 1 November 2018. However, MH products placed on the market before 1 November 2018 which do not comply with the new requirement (i.e. existing labelled stock) have been allowed a grace period of six months for sale, and a further 12 months for use.

CRD have also requested that authorisation holders and industry partners develop and implement a stewardship programme to ensure compliance with the restriction, so that there is continuing safe use of MH and product registrations are maintained.  As further information becomes available, this will be communicated.
