It's crucial for controlling plant diseases in agriculture. By eliminating one host plant, the disease cycle can be broken.

Heteroecism requires two different host species, while autoecism completes the entire life cycle on a single host species.

Rarely. It's occasionally extended metaphorically in ecology, but remains primarily a mycological term.
