Phosphite barriers for Kauri Dieback – Scoping exercise
Plant & Food Research
Undertake a scoping exercise to assess the feasibility of using phosphite as a barrier treatment to contain disease foci and to prevent incursions of PA into new areas. Approach consist of a foliar spray and inject all plants/trees where applicable to create a barrier or buffer around an infected site or to protect disease-free areas.
A number of potential barriers/uncertainties (e.g. technical, financial and political) would need to be addressed for the research to be successful. High up-font costs and likely duration of between 10 to 15 years are also factors to be considered.
