Summary: Aquilegia downy mildew is caused by a species of Peronospora which is currently unnamed. The first occurrence of the disease appears to be on a nursery in 2011, with more widespread reports in gardens during 2013. Little or no work has been published on the disease and as a result it is difficult to establish from the literature why the disease has become more prevalent. This project aims to establish the main sources of inoculum for the disease on nurseries

Aims and Objective: 

The project aims to generate data which will enable growers to combat the threat from the newly emerging downy mildew on aquilegia (ADM).

Project objective(s):

1.    To determine whether the Peronospora sp. responsible for ADM is present in seed batches and whether infected seed could act as a primary source of infection.

2.    Dissemination of results.
