Denomination of a new race of Bremia lactucae, Bl: 37EU

Nunhem, 1 June 2021 | Bron: Plantum

The International Bremia Evaluation Board Europe (IBEB-EU) has collected more than 500 Bremia isolates in European lettuce in 2019 and 2020. Most isolates are local variants. However, one type of isolate appeared to spread initially especially in France but recently also in Spain, Portugal and Italy. This variant is expected to spread also to other centres of lettuce production in Europe. The IBEB-EU decided to denominate this variant as race Bl: 37EU. The Board emphasizes the importance of chemical control and hygiene measures in addition to the use of resistant varieties to prevent the development of new races.


BASF offers a wide range of lettuce varieties, with broad resistance patterns and most resistant to this new race Bl:37EU. Updated resistance information of the Nunhems lettuce assortment can be found in the lettuce crop tables on our website.
