UPDATE: GREEN LEAF, ICEBERG, AND ROMAINE

September 11, 2026

Due to the recent heat and the presence of Impatiens Necrotic Spot Virus (INSV) in the Salinas and Santa Maria Valleys, many iceberg growers have lost as much as 20% of their yields. Strong processor demand is fueling this market, which will reach $30+ next week, possibly higher. Green leaf and romaine have been subjected to the same challenges. Markon First Crop (MFC) Green Leaf, Iceberg, and Romaine Lettuces are available in Salinas, California; Markon Best Available (MBA) is being substituted as needed due to low weights.
