V. Application Methods Include: Ground boom, Airblast sprayer, Aerial by fixed wing or helicopter, granular spreader, selective wiper application, spot treatment with hand-boom or back pack-mist blower.

VI. Determine the most effective method of application by considering:

  • The effectiveness of coverage and distribution provided by equipment, or if the terrain is uneven and or rocky, for herbicide, insecticide and fungicide treatments.
  • The effectiveness of the product and it’s formulation for controlling the pest outbreak.
  • If plants are emerged in the field, or if terrain is uneven and or rocky, damage to the plant and fruit by the application method.
  • The time available to treat pest once threshold or threat has been identified.
  • The proximity to sensitive areas.
  • Availability of application equipment and custom applicators.

VII. Use cultural controls first. Refer to:

Fact Sheet No. 252 – Cultural Management for Weeds in Wild Blueberries
