While reported as a weed within our state more than 50 years ago, green kyllinga (Kyllinga brevifolia) has developed into a major turfgrass problem over the last 10-15 years. Once established in turfgrass or ornamental areas, spread can be rapid. Mowing, foot traffic, and cultivation spread both seed and rhizomes.

In addition to reducing the aesthetic quality of turf, the uneven growth rates turf and green kyllinga produces an undulating or irregular surface in infested areas. This uneven surface is of particular concern for athletic fields and golf courses.
