Removal of Hort16A canopies

26 June 2014

Growers in the process of removing Hort16A should ensure canopies are well protected with copper sprays to minimise the chances of infection and Psa-V spread. Ideally, remove any Psa-V infected material and dispose of it by on-site burial or burning. If removed canopy is remaining within the block, fine mulching and use of digesters to speed break-down of is highly recommended.

Psa-V can survive for at least 15 weeks on the orchard floor in prunings and infected plant debris, presenting an ongoing Psa-V risk. Removal of this material will benefit new grafts next spring.

This recommendation also applies to any canopies where infection may be present.
