LIVE FROM THE FIELDS: WEST COAST DISEASE PRESSURE

September 28, 2026

Please click here to view a Markon Live From the Fields video about plant virus and disease pressure that is heavily impacting lettuce crops in California’s Salinas and Santa Maria Valleys.

  • Impatiens Necrotic Spot Virus (INSV) and other soil diseases are decimating yields in lettuce crops
  • Growers are entering fields one to two weeks ahead of schedule to minimize losses
  • Harvesting crews are trimming heavily to detect and avoid affected heads
  • Case weights and raw product bin weights have been dropping and are expected to remain below normal for the rest of the season
  • Most suppliers anticipate an early end to the Salinas and Santa Maria seasons as a result of the current yield loss challenges
