We introduce our breakthrough in iceberg lettuce cultivation: new iceberg varieties with a complete protection package—full Bremia resistance, Nr:0, and Intermediate Resistance (IR) to Nasonovia Nr:1 (IR). The Nr:1 biotype of Nasonovia aphids has become a major threat to lettuce growers in Europe. With chemical controls losing effectiveness and resistance on the rise, growers have fewer options. That’s why resistance makes the difference.
With Nasonovia Nr:1 Resistance, protection starts from within. It is very easy spotting our Nasonovia Nr:1 (IR) resistant varieties, it will only take one glance! Just look for the Nasonovia resistant label you see here.
Nasonovia ribisnigri, commonly known as the lettuce aphid, is a major pest affecting lettuce crops globally. It damages plants by extracting sap and transmitting viruses, leading to distorted leaves, stunted growth, lower yields, and rejection from retailers. Its rapid reproduction makes traditional control methods less effective plus EU restrictions on chemical pest management are leaving growers with fewer tools to fight Nr:1.
EU regulations are phasing out chemical controls, leaving lettuce growers seeking IPM strategies and trialing biocontrols. Retailers’ strict aphid tolerance is putting pressure on producers, particularly in whole-head and processing markets where visual quality is key.
We’re introducing new iceberg varieties with Intermediate Resistance to NR:1, being among the first in the market.These varieties also incorporate our most complete resistance package: Full Bremia (Bl:29-41) and HR: NR:0, offering a comprehensive protection package.
