What is "frass" in the context of turfgrass?

Frass refers to the insect digestive waste that accumulates as a byproduct of feeding. In the context of turfgrass, frass can come from various insects, particularly those that are herbivorous and leave behind droppings as they consume plant materials. This organic waste can have beneficial properties, serving as a natural fertilizer by adding nutrients back into the soil. It can promote soil health and improve overall turfgrass growth when present in the proper amounts.

The other options do not accurately describe frass; it is not a type of grass seed, nor is it a specific pest that harms turfgrass, nor a method of pest control. Understanding what frass is and its role in the ecosystem can help turfgrass managers utilize it to enhance soil health while being mindful of pest populations.
