Water Management
Overview
Water management strongly influences crop stress, humidity, root health and pest pressure.
Irrigation strategy is therefore an important component of Integrated Pest Management (IPM).
IPM relevance
Poor water management may contribute to:
- plant stress
- weak growth
- humidity instability
- root disease risk
- sciarid fly pressure
- slug pressure
- biological control disruption
Environmental influence
Water affects:
- canopy humidity
- substrate oxygen
- transpiration
- crop temperature buffering
- root activity
- nutrient uptake
Environmental stability is often linked closely to irrigation consistency.
Crop stress interaction
Both overwatering and underwatering may increase susceptibility to pest pressure.
Stressed crops are often more vulnerable to:
- spider mites
- aphids
- thrips
- root-feeding pests
