Bermuda grass is a turf species of grass weed, which is used in sports fields and in lawns throughout the world. It is resistant to warm weather and wears well with heavy traffic. Bermuda grass, although desirable in some lawns, is considered a weed. It is invasive if allowed to grow in areas where it is not native, choking of the ecosystem and limiting biodiversity. A perennial grass that can multiply by seed or underground rhizome, Bermuda grass is difficult to control.
Purchase a selective herbicide that contains sethoxydim, fluazifop or clethodim. Selective herbicides will not affect plants other than Bermuda grass.
Spray the grass in the early spring, between April and May, when the Bermuda grass is less than 6 inches in length. Apply again after two weeks of growth.
Remove Bermuda grass that did not die by hand, digging up the soil to remove the rhizome from underground. If a small amount of rhizome is left, the weed will return.
Place black plastic over the section of Bermuda grass if the herbicide does not kill the grass. Attach the black plastic with stakes in the ground. Sun heats the black plastic, killing the grass underneath. Leave the plastic for 6 to 8 weeks.
