Copper products added to KVH Recommended Product List

Kocide® Opti™ now has a full-label claim for the control of Psa. This was approved by the ACVM group of the Ministry for Primary Industries (MPI) on 31 July 2014. Kocide® Opti™ is a copper hydroxide product which may be applied throughout the year within a Psa-V management programme. It should not be applied to open flowers. The recommended application rate for dilute spraying is 70–90gms/100L.

HORTCARE® Copper Hydroxide 300 also received a new registration from ACVM on 1 August 2014 with a limited label claim granted for the control of Psa-V. When dilute spraying the recommended application rate for this product is 50-90gms/100L through the budbreak to harvest period; and 70–90gms/100L through the post-harvest and dormancy periods. Again, avoid application to open flowers.

The KVH Recommended Product List has been updated to include these products and they will also be included in the 2014-2015 ZESPRI Crop Protection Standard for Psa control.
