What is defined as a "pathogen"?

A pathogen is an organism that is capable of causing disease. This definition encompasses a wide range of organisms, including bacteria, viruses, fungi, and parasites, that directly disrupt the normal biological functions of their hosts. In the context of turfgrass and other plants, pathogens can lead to various diseases that impair the health, growth, and aesthetic quality of the grass. Understanding that a pathogen specifically refers to a disease-causing organism is crucial for effective pest management, as it helps identify and implement strategies for mitigating damage and promoting recovery in affected areas.
