Manage Navel Orangeworm—Bloom to Postbloom

These activities are critical during the bloom to postbloom period for navel orangeworm management:

  • Remove mummies from trees by February 1.
  • Disk or flail by March 15 to destroy mummies and the navel orangeworm larvae within them.
  • Hang egg traps during the first week of April to track navel orangeworm development throughout the season and to determine a biofix date to start accumulating degree-days.
