IV. Follow methods in fact sheets to minimize of- target deposition. Refer to:
- Fact Sheet No. 303, Minimizing Off-Target Deposition of Pesticide Applications
- Fact Sheet No. 250, Hexazinone Best Management System for Wild Blueberry Fields
- Fact Sheet No. 237, Glyphosate for Weed Control in Wild Blueberries
- Fact Sheet No. 235, Postemergence Grass Control for Wild Blueberries
- Fact Sheet No. 234, Calibration of Granular Applicators for Herbicide Impregnated Fertilizer
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 have emerged in the field, or if the 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
- Fact Sheet No. 253, Cultural Management for Insects and Diseases in Wild Blueberries
- Fact Sheet No. 254, Cultural Management pH
