‘The vines re­ally rel­ish the ozone’

The Orchardist - - News -

Tau­ranga ki­wifruit post-har­vest op­er­a­tor Al­lan Daw­son over­sees a two-hectare block which, hav­ing been in­fected with Psa, is be­ing tri­alled with a BioFume over­head ozone-spray­ing sys­tem.

“What we've no­ticed with the ozone is a marked im­prove­ment in the leaf health and gen­eral vine health,” he says. “We're also see­ing lower num­ber of problems with in­sects so it's con­trol­ling them as well.”

While they sprayed cop­pers over win­ter, in the flow­er­ing pe­riod they dropped the usual fungi­cide pro­gramme in favour of us­ing ozone and that worked a treat, with no im­pact on the bees, Daw­son adds.

And though the vines showed a small num­ber of leaf-roller in­sects when they came into leaf, that was quickly com­bated by in­creas­ing the du­ra­tion of the ozone spray­ing.

“I see this as a rel­a­tively cheap way to ap­ply pro­tec­tion to your vines,” Al­lan Daw­son says. “The vines re­ally seem to rel­ish hav­ing ozone put on them.”
