Assessing the effectiveness of oxathiapiprolin toward Phytophthora agathidicida, the causal agent of kauri dieback disease.

ABSTRACT: Phytophthora species cause disease and devastation of plants in ecological and horticultural settings worldwide. A recently identified species, Phytophthoraagathidicida, infects and ultimately kills the treasured kauri trees (Agathis australis) that are endemic to New Zealand. Currently, there are few options for managing kauri dieback disease. In this study, we sought to assess the efficacy of the oomycide oxathiapiprolin against several life cycle stages of two geographically distinct P. agathidicida isolates. The effective concentration to inhibit 50% of mycelial growth (EC₅₀) was determined to be ∼0.1 ng/ml, indicating that P. agathidicida mycelia are more sensitive to oxathiapiprolin than those from most other Phytophthora sp
