Have you ever wondered why disease pressure can feel more intense inside your High Tunnel, even though crops are protected from the elements?
If you’re doing everything “right” but still seeing fungal or bacterial issues pop up, you’re not alone. High tunnels create a productive growing environment—but without proper management, that same protection can also create ideal conditions for pathogens to thrive.
Why Pathogen Control Is Unique Inside a High Tunnel
A High Tunnel creates a semi-controlled environment that protects crops from wind, rain, and extremetemperatures—but that protection can also favor pathogens if conditions aren’t managed carefully. Unlike open-field production, moisture and heat can become trapped, creating ideal conditions for fungal and bacterial diseases.
Common tunnel-related pathogens thrive when:
- Humidity remains consistently high
- Leaf surfaces stay wet for extended periods
- Air circulation is limited
- Temperatures fluctuate rapidly
