Once you have identified dallisgrass in your St. Augustine lawn, you can begin treating it. There are a few different ways to treat dallisgrass, but the most effective way is to use a combination of cultural and chemical controls.

Cultural Controls

Cultural controls are non-chemical methods that can help to reduce the population of dallisgrass in your lawn. These include:

• Regular mowing: Mowing your lawn regularly will help to remove dallisgrass seedlings and prevent them from becoming established. Mow your lawn at the recommended height for your grass type, and be sure to remove all clippings.
• Aeration: Aerating your lawn will help to improve drainage and air circulation, which can make it more difficult for dallisgrass to thrive. Aerate your lawn in the spring and fall.
• Watering: Watering your lawn deeply and infrequently will help to strengthen your grass and make it more resistant to dallisgrass. Water your lawn deeply once or twice a week, and be sure to water early in the morning or late in the evening.
• Fertilizing: Fertilizing your lawn regularly will help to promote healthy growth and make your grass more resistant to pests and diseases. Fertilize your lawn according to the package directions.

Chemical Controls

If cultural controls are not enough to control dallisgrass, you may need to use chemical controls. There are a number of different herbicides that can be used to kill dallisgrass, but the most effective herbicides are those that contain the active ingredient quinclorac. Quinclorac is a systemic herbicide, which means that it is absorbed by the leaves of the dallisgrass plant and translocated throughout the plant, killing it from the inside out.

When using chemical controls to treat dallisgrass, it is important to follow the directions on the product label carefully. Be sure to wear gloves and eye protection when applying the herbicide, and keep children and pets away from the treated area.
