Is carpet grass a weed in your lawn?

Often carpet grass is used as a turf - it is well suited to shaded areas, for example. But more commonly, it appears as a weed in high quality turf areas where removal can be difficult.

Nominally, MSMA and DSMA are used for many grasses as post emergence herbicides. But with carpet grass, it seems as if there is relatively little effect, as it quickly regrows from rhizomes. It is worse in the warmer regions as carpet grass can grow quite quickly, even after spraying.

What is your experience? Is there a reasonable solution that can provide cost effective control of both narrow and broad leaved carpet grass?

Comments welcome.
