Investigate the ecology of PA control tools. Phase 1: In Vitro Proof of Concept. Proof of concept to determine the effectiveness of PA against PA. Phase 2: Seedling trials: Kauri seedlings that have been inoculated with PA are treated with PA.
Trunk injections showed the most promise whereas Phosphorous acid, applied as a soil drench or foliar spray, was less effective. Phosphite injections via field trials were recommended.
