Codling Moth: Second generation codling moth is beginning to emerge in Cleveland County and similar elevations (about 800 to 1000 ft), while at higher elevations we remain between generations. Insecticide use at this time should not be necessary in the majority of orchards in Henderson or Wilkes Counties.

Codling moth DD accumulations in Cleveland County are about 1260. While pheromone trap captures are the best indicator of activity, in orchards with low populations (i.e., no damage by first generation larvae and low pheromone trap captures), a single application timed at about 1400 DD is often sufficient for second-generation control. When choosing an insecticide to use for second generation codling moth, remember to use a product that was not used during first generation flight. In orchards using mating disruption, it is highly unlikely that insecticides are necessary for second generation codling moth.
