What does exclusion refer to in the context of disease management?

Exclusion in the context of disease management specifically refers to the practice of keeping plant pathogens away from crop plants. This is achieved through various methods that limit the introduction and establishment of pathogens in agricultural settings. By implementing exclusion tactics, such as proper sanitation, careful management of planting materials, and physical barriers, growers can create an environment that is less conducive to pathogen survival and spread.

This approach is essential for preventing disease outbreaks before they can take hold, thus protecting crop health and maximizing yield. For instance, ensuring that planting materials are free of pathogens or employing clean tools and equipment can significantly reduce the risk of disease. Exclusion is a proactive strategy that works in tandem with other management practices, enhancing the overall effectiveness of disease control measures.
