A new race of Bremia lactucae, Bl: 36EU identified and denominated in Europe.
The International Bremia Evaluation Board for the EU (IBEB-EU) has evaluated all Bremia races found in 2017 and 2018. Many outbreaks of Bremia were caused by new Bremia races with only local importance. However, one race spread in most European counties and IBEB-EU decided to denominate this isolate as the new race Bl: 36EU.
Proper hygiene practices, such as removal of debris and diseased plants, will always reduce the spread of Bremia in lettuce crops.
The board emphasizes that those resistances should not be understood as a full insurance against Bremia. Occasionally, problems may occur due to a local new isolate that does not survive over years and does not spread to other areas.
Therefore, chemical control and hygiene measures will be important for any lettuce variety. Fungicide application, especially in a young plant stage, gives additional protection to resistant lettuce crops, and will help prevent the development of new Bremia races.
Aware of this major issue for the safety of your crops, Gautier Seeds already offers Bl:36EU resistant varieties, to help you fight against Bremia attacks.
