corn

OBJECTIVES:

  • Refine corn earworm monitoring techniques using pheromone and black light traps.
  • Continue developing a statewide pheromone trapping program.
  • Study earworm flight and infestation trends that can be used to predict damaging infestations.
  • Develop corn earworm and sweet corn development models.
  • Conduct insecticide trials to determine if and when sprays are most effectively used.
  • Incorporate relevant information into a damage prediction model that can be used for management purposes.
