BioGro lowers copper input limits for organic production

19 September 2019

BioGro has confirmed that from last Wednesday 11 September 2019, the limit on the use of copper-based inputs for organic production has been lowered to 3kg active copper/ha/year.

This applies to all BioGro Licensees and flags the end of an interim exemption which allowed a temporary increase to 6kg/ha/year to support growers in the control of Psa following the disease’s outbreak.

BioGro certified products with ACVM registration for Psa affected by this change include Nordox 75WG, AG Copp 75, Champion++, and Hortcare Copper Hydroxide 300.

BioGro Licensees should contact the BioGro office with any queries or concerns regarding this change.
