Greenhouse and high tunnel environments, which tend to be warm and humid, often create ideal situations for disease development. Because diseases can cause extensive damage, their management is essential to production of high quality, marketable products. While challenging, these environments can be managed to simultaneously encourage plant growth and discourage pathogen spread.
This publication discusses greenhouse/high tunnel disease management in terms of relative humidity, temperature, sanitation, water management, and soil management. A listing of additional resources is also provided in this fact sheet.
Managing Greenhouse & High Tunnel Environments to Reduce Plant Diseases (PPFS-GH-01) is available online.
