Plant diseases don't occur by chance—they develop when three conditions come together: a susceptible host, a pathogen and a favorable environment. This white paper explains the Disease Triangle and shows how organic and regenerative farmers can reduce disease pressure by strengthening plant health, improving soil biology and managing the growing environment.
In this white paper, you'll learn:
How the Disease Triangle explains why plant diseases develop.
The roles of the host, pathogen and environment in disease outbreaks.
How healthy soils and balanced nutrition improve a plant's natural defenses.
Practical strategies to reduce disease pressure through crop rotation, resistant varieties, sanitation and cultural practices.
Why prevention is more effective than relying solely on disease treatments.
How organic farming systems can create healthier, more resilient crops by supporting the entire farm ecosystem.
