KeyStrepto/Copper resistance testing

As reported in the KVH Bulletin (19 June) ongoing testing as part of the KVH/Zespri R&D programme is underway to identify early any strains of Psa-V showing potential resistance to protective compounds.

The latest results from Verified Lab Services (VLS) for Streptomycin/copper resistance testing confirms to date, no resistance has been detected.

This is an ongoing testing programme. In future we are looking to improve the testing process by including more KPIN samples and extending outside the Te Puke region.

Growers who have used KeyStrepto™ or copper and would like to be part of the resistance monitoring programme by allowing samples to be collected from their orchard can register their interest with KVH at [email protected].
