Mating disruption for dogwood borer (Isomate-DWB) and peach tree borer (Isomate-PTB Dual)

Immigration of mated females into the orchard from adjacent areas will reduce control. Supplemental insecticides may be required for several years to help bring populations down to levels where mating disruption can be used alone for management of borers.

For dogwood borer:

  • Place dispensers on lateral branches at chest height within the canopy.
  • Apply before adult borer emergence begins (typically end of May).
  • Use a high rate (375 dispensers/ha) for the initial treatment year and for high populations.
  • Increase the rate (maximum 500 dispensers/ha) around borders of treatment area.

For lesser peach tree borer and peach tree borer:

  • Apply uniformly throughout the treatment area.
  • Place dispensers on lateral branches in mid-point of tree canopy.
  • Apply before adult borer emergence begins (typically at or before shuck split).
  • Dispensers are designed to last for the entire season.
  • Use a higher rate (maximum 675 dispensers/ha) when pest pressure is high.
