Two reports on work underway in the Kauri Dieback Management Programme were presented at the New Zealand Plant Protection conference in Napier earlier this month.
Dr Nick Waipara (Auckland Council Biosecuri ty) presented and published the following journal paper :
Surveillance methods to determine tree health, distribution of kauri dieback disease and associated pathogens. N.W. Waipara, S. Hill, L.M.W. Hill, E.G. Hough and I.J. Horner 2013. New Zealand Plant Protection, Volume 66: 235-241
The paper summarises the results of Auckland Council's passive surveillance programme (2008-March 2013) to assist private landowners and community report sick trees and receive diagnostic testing and management advice. The diagnostic and research undertaken was in collaboration with Plant & Food Research and clearly demonstrated kauri dieback is serious and widespread problem for Auckland landowners. Management implications included containing the disease, protection healthy stands, significant cost implications for removing dead trees and the urgent need for control tools.
Collaborators Dr Ian Horner and Ellena Hough (Plant & Food Research) also published their results to date summarising the increasing potential of using phosphite as management tool against kauri dieback.
Phosphorous acid for controlling Phytophthora taxon Agathis in kauri: glasshouse trials. I.J. Horner and E.G. Hough 2013. New Zealand Plant Protection Volume 66: 242-248
Both kauri dieback papers were very well received by the science / research organisations as well as plant industry based sectors, with several offers of collaboration (including in-kind contribution from Lincoln University and BioProtection) for the programme to develop wider research linkages to help answer some the Council's key knowledge gaps around its kauri dieback management objectives.
Both papers can be found on the Documents and Resources page.
