Cynodon is a genus of plants in the grass family.[2] It is native to warm temperate to tropical regions of the Old World, as well as being cultivated and naturalized in the New World and on many oceanic islands.

The genus name comes from Greek words meaning "dog-tooth". The genus as a whole as well as its species are commonly known as Bermuda grass or dog's tooth grass.

Cultivation and uses

Some species, most commonly C. dactylon, are grown as lawn grasses in warm temperate regions, such as the Sunbelt area of the United States where they are valued for their drought tolerance compared to most other lawn grasses. Propagation is by rhizomes, stolons, or seeds. In some cases it is considered to be a weed; it spreads through lawns and flower beds, where it can be difficult to kill with herbicides without damaging other grasses or plants. It is difficult to pull out because the rhizomes and stolons break readily, and then re-grow.

It is also noted for its common use on the surface of greens on golf courses, as well as football and baseball playing fields.

Recent news reports claim that a Bermuda-derived F1 hybrid called Tifton 85 suddenly started producing cyanide and killed a cattle herd in Texas, USA.[5][6][7]
