Abstract
Downy mildew (Bremia lactucae) is the main disease of artichoke cultures in Brittany.
Because this disease is rare in the rest of the world, only few teams work on this subject.
For this reason a research program was carried out at BBV, in collaboration with the Chamber of Agriculture of Finistere and the CATE experimental station.
The aim of this project was to improve our knowledge on the Bremia lactucae, pathogen of artichoke.
Forty isolates of Bremia lactucae were collected in all areas of Brittany, on different cultivars of artichokes and cardoon.
Isolates of Bremia lactucae of artichoke and lettuce were characterised and compared with molecular techniques.
Based on the publications on B. lactucae on lettuce, we identified suitable conditions for downy mildew infection in our growth chambers.
The method of inoculation of whole young plants of artichoke is now set up.
A second test on foliar disk is already on trial.
These tests will help, on one side, to evaluate the life cycle of Bremia lactucae of artichoke, and, on the other side, to evaluate the efficiency of phytosanitary products, conventional chemicals or alternative products.
