It is also proposed that Gibberellic acid be exempt from a MRL and a limitation on its maximum use rate is alternatively proposed. Accordingly, it is proposed that the following entry be added to the Second Table of the New Zealand (Maximum Residue Limits of Agricultural Compounds) Mandatory Food Standard 1999:

Substance	Conditions or Limitation
Gibberellic Acid (gibberillins GA3, GA4and GA7and Potassium Gibberellate)	As a plant growth regulator applied at <200 g ai/ha/year.
