Syngenta and D'Arrigo California Romaine Lettuce Success Story
Discover how Syngenta Vegetable Seeds is transforming romaine lettuce production with innovative solutions. This grower testimonial features D'Arrigo California sharing their experience with Syngenta's high-quality romaine varieties, including Stampede. Learn how Syngenta's partnership approach and rapid response to challenges like INSV are supporting long-term success for lettuce growers.
By understanding growers' challenges, Syngenta develops targeted solutions for their long-term success and evolving agricultural needs.
We’d seen Stampede hold up to the INSV in trials, so we decided to move forward with it. When Syngenta saw there was a need for Stampede, they were able to move pretty quickly in terms of getting seed out there for the growers.”
