Pathogen

Definition:

A biological agent that causes disease or harm to its host. Pathogens, such as fungi, are almost always present in the environment and are prevalent causes of lawn and tree disease. Disease occurs when the lawn or yard is not cared for properly and when the environment favors the pathogen. Proper care for a lawn, such as adequate drainage, avoiding over fertilization, and maintaining adequate air movement can help reduce instances of tree and lawn diseases.
