ECB populations remain generally low however, scattered reports of feeding on conventional corn indicates the pest is still present and will always pose a potential threat.

  • In 2019 the early and late-planted conventional fields will be most attractive to egg-laying 1st and 2nd generation moths.
  • ECB can produce 2 and sometimes 3 larval generations per season depending on GDU accumulation.
  • Risk of yield loss can be reduced if you scout fields and apply a labeled insecticide as needed.
  • Larvae are susceptible to insecticides for 10-14 days during each generation
  • Water volume is critical with insecticide applications and presence of heavy dew enhances performance.
