What is "frass" in the context of turfgrass?

Frass refers to the insect digestive waste that is produced by various pests, particularly those that bore or feed on plants, such as turfgrass. This waste is significant in the ecological context as it contains nutrients that can enrich the soil, thereby acting as an organic fertilizer. When insects process plant material, the resulting frass is often rich in nitrogen and other essential nutrients. This contributes to soil health and can enhance plant growth, making it a valuable component in turfgrass management.

The other concepts, such as a type of grass seed or a method of pest control, do not pertain to frass, which is specifically related to the byproducts of insect activity. Similarly, while there are pests that harm turfgrass, they do not define what frass is; rather, frass is a byproduct of those pests. Understanding frass in the context of turfgrass highlights its dual role as a byproduct of pest activity and a potential benefit to the ecosystem when managed properly.
