How to Control Bahia Grass

Overview

Bahia grass (Paspalum notatum) is a warm-season perennial grass commonly planted across the southern United States as a turf grass, for erosion control and in pastures. Many consider Bahia grass highly invasive and unsightly. The stalks are thick, which makes them difficult to mow, and the blades tend to have a frayed look. The grass readily seeds itself, which makes the grass appear unlevel with seed pod production. Take action to control it.

Step 1

Mow the grass every 7 to 14 days to a height of 3 inches. Regular mowing will prevent seed pod formation, which will help limit the spread of the grass.

Step 2

Apply a glyphosate herbicide according to the directions on the label, using a handheld garden pump sprayer or a backpack sprayer. Glyphosate will kill other grasses and plants, so take care when using the product.

Step 3

Apply a herbicide that contains metsulfuron to control bahia grass that has invaded Bermuda grass. Follow the directions on the label for application instructions. The metsulfuron will not harm the Bermuda grass. Apply metsulfuron in the spring for best control

Step 4

Apply multiple applications of arsonate herbicides (DSMA or CMA) throughout the growing season. Follow the directions on the label for application.
