Syngenta's Breakthrough INSV-Resistant Romaine: A Game-Changer for the Lettuce Industry

The Salinas Valley is home for lettuce growers. They have tamed the valley’s fertile soil for decades, even through a host of challenges. In 2019, Impatiens Necrotic Spot Virus, or INSV, arrived. Riding in on an insect called the Western flower thrip, it wreaked havoc on Salinas Valley romaine lettuce fields. In 2020, the Grower-Shipper Association estimated $100 million in lost revenue1. Once verdant fields turned a ghastly bronze hue, no matter what growers tried.

Come 2021, some growers left the Salinas Valley, to find greener pastures. But the Salinas Valley is where our heroes belong. Growers were desperate to stomp out INSV so they could return to harvesting the crisp lettuce the country was craving from the Salinas Valley. And then, a new player stepped into the chute, ready to explode into action. STAMPEDE romaine lettuce arrived commercially in 2022—after successful Salinas Valley trials—from Syngenta Vegetable Seeds. Syngenta is a trailblazer known for innovative solutions that help growers get more out of their crops. And boy howdy, does Syngenta deliver with STAMPEDE.
