The dataset identifies confirmed infections of Phytophthora austrocedri in Great Britain.
P. austrocedri is a species of Phytophthora that was only recently ‘described’ (in 2007), although it is thought to have been present in Argentina and Chile for at least 50 years. The recent discoveries of the pathogen are a concern because of the often fatal nature of infection of the host plant, and because the recent findings of P. austrocedri in the UK are the first confirmed findings of this pathogen in the UK. The current reported distribution of P. austrocedri is limited to Argentina, Chile and the recent findings in the UK. It is not known how the pathogen entered the UK. Scientists believe it is spread by water, infected plant material and contaminated soil, making it difficult to control.
The dataset identified confirmed infections in England. Management decisions are taken on a case-by-case basis according to the specific circumstances of the findings. Eradication is the objective where feasible, but in some cases this will not be practicable, so containment is likely to be the goal.
