The multi-cultivars are trialed for micro-climate adaptation,
hybridization and are evaluated for viability, productivity, and
marketability.
The arbor is a T-bar design consisting of 8 foot, 8 inch circumference
CCA (chromated copper arsenate) driven tie backs and line posts.
CCA posts fit the requirements of hardy kiwi in uniformity, strength,
and endurance but not for that of "organic" hardy kiwi.
I have been told of three alternatives to CCA, those named are:
(ACQ) ammoniacal copper quartenary
copper azole
copper citrate
My question is how do these alternatives to CCA fair with the Organic
Standards and are there any other alternatives to be considered?
Thank you.
