  • Quality issues such as decay, growth crack, insect pressure and damage, Impatiens Necrotic Spot Virus, and sunscald are already problems
  • Shorter days will somewhat limit heat-related defects and promote growth
  • Above-normal temperatures will increase insect pressure, prolong virus/disease issues, and continue to negatively affect volume and quality

Santa Maria

  • By Monday, September 28, temperatures are expected to hit the mid-80s for three to five days
  • Strawberry supplies are limited due to previous heatwaves over the last two months
    • Expect persistent heat-related challenges and reduced yields
    • Bleeding, bruising, pin rot, small size, softness, and shortened shelf-life are already present
  • Iceberg and green leaf lettuces are exhibiting virus issues and internal burn; yields are reduced due to smoke and heat, but quality is starting to improve

Huron

  • Suppliers are targeting mid-October to begin the iceberg season
  • Peak temperatures in low the 100s are expected by Tuesday, September 29 and Wednesday, September 30
  • Plant maturity will be monitored for potential die off due to the abnormally hot temperatures  
  • Most suppliers are confident that younger plant maturity will limit damage
