Almond orchard edge spray is a targeted pest management strategy used during early hull split to protect the most vulnerable areas of almond orchards. This critical treatment focuses on spraying the orchard’s perimeter rows, where pest pressure, especially from navel orangeworm (NOW), is typically highest. A well-timed edge spray can significantly reduce NOW infestation, saving thousands in potential crop losses.
Understanding Almond Orchard Edge Spray
Almond orchard edges are more exposed to pests, particularly navel orangeworm, due to nearby non-cultivated areas or adjacent crops. These edge rows often experience higher infestation rates—up to 50% more than interior rows. Applying edge sprays just before or at early hull split can reduce pressure before a full-block application.
Tips for Timing and Scouting
To effectively time your edge spray:
- Check for early hull split in the top third of the tree.
- Monitor pheromone traps for NOW activity.
- Look for egg presence using egg traps near orchard borders.
- Watch surrounding fields, NOW often migrates from nearby crops.
- Use dust monitoring tools to determine if extra dust suppression is needed.
Focus on south and west-facing edges, as they tend to split earlier and attract more pests.
Best Practices to Reduce Navel Orangeworm Infestation
In addition to edge sprays, follow these integrated practices:
- Mummy nut removal: Aim for less than 2 nuts per tree.
- Minimize dust: Use water trucks before and during harvest.
- Avoid overlapping sprays to limit resistance.
- Use AgNote to document spray intervals and materials.
- Keep canopy open to promote spray coverage and drying.
Spray Drift and Application Efficiency
Drift can reduce coverage by 20–30% on target areas, especially on windy days. To improve precision:
- Spray in early morning or evening when winds are low.
- Use proper nozzle calibration.
- Monitor coverage with spray cards.
