Outdoor & Protected Cultivation
Outdoor IPM, Beneficials & Edge Scouting
Outdoor pest pressure is dynamic because crops are connected to surrounding vegetation and beneficial organisms. Edge scouting, organism identification, and population trends are more informative than reacting to every insect found on a plant.
Key concepts
- Crop edges can receive different pest pressure than interior plants
- Predators, parasitoids, pollinators, and neutral arthropods should not all be treated as pests
- Weather can rapidly change pest and beneficial populations
- Damage level and population trend matter alongside presence
What to measure or observe
- Scout edge and interior zones separately
- Record pest and beneficial organisms
- Inspect multiple life stages and damage patterns
- Revisit hotspots after weather or management changes
Common mistakes
- Treating all insects as harmful
- Scouting only the easiest plants to reach
- Applying a control before identifying the organism
- Ignoring surrounding host vegetation
