Syngenta Launches INSV Disease Resistant Romaine Lettuce
The Heroes of America’s Salad Bowl
For the last several decades, the Salinas Valley has been home for lettuce growers. Bountiful harvests and thriving crops painted a picturesque scene of prosperity, and the valley was known far and wide as America’s Salad Bowl. Lettuce growers, true cowboys of the land, have tamed the valley’s fertile soil for decades, sowing the seeds of abundance with their unwavering determination. These heroes have worked hard, day in and day out, to cultivate the finest leafy greens this country has ever seen. Working the land has always come with a host of challenges, but the tenacious Salinas Valley growers have long since been steadfast in their dedication to nourishing their community.
A Villain Called INSV
Alas, trouble arrived in the form of a vicious villain named INSV, short for Impatiens Necrotic Spot Virus. This nasty virus rode in on a tiny insect called the Western flower thrip, and wreaked havoc on the romaine lettuce fields, spreading like wildfire and leaving a trail of crop failure in its wake. Though INSV was first discovered in the Salinas Valley in 2006, it wasn’t until 2019 that it led to consequential crop loss. The problem worsened year after year, with a staggering estimated $100 million in revenue lost in 2020, according to the Grower-Shipper Association1.
Once verdant lettuce fields showed signs of trouble as leaves turned a ghastly bronze hue. No matter how growers tried to bag or remove the infected plants, the virus was relentless in spreading throughout entire crops. Field after field collapsed like a calf giving in to a roper, leaving the land barren and the growers distraught.
Come 2021, growers were finding unique ways to dodge the virus and the devastation it brought, moving crops outside of the Salinas Valley. This proved to be a decent short-term solution, bringing some growers’ crop yields back up to 70%, according to California Ag Today2. But the Salinas Valley isn’t just any old place. It has earned its reputation for a reason, and it’s where our heroes belong; displacement is neither ideal nor feasible for all lettuce growers. In 2021, the virus pressure eased up a bit in the Salinas Valley in general, due to weather conditions. But as any cowboy knows, climate conditions can be as capricious as a buckin’ bronc in a weathered arena.
A long-term solution was needed, and fast. Growers were desperate to stomp out INSV once and for all so they could return to harvesting the crisp green lettuce the country was craving. With agricultural researchers and plant pathologists on the case, they trusted a solution would eventually come, but they worried that it might be several years down the line. In the meantime, growers expected they would continue to struggle with INSV and the intense disease pressure that would dramatically affect yields and the feasibility of growing certain lettuces at all. The future of their romaine crops hung in the balance, regardless of how much tenacity and determination the master growers exhibited.
With a feeling of defeat hanging in the air, tinged with a palpable anticipation of a solution on the distant horizon, a new player stepped into the chute, ready to explode into action.
