Step 1: Identification - First, are you completely certain that the unwanted vegetation that is growing on your lawn is indeed dallisgrass? It is important to properly ID the plant you want to be removed because herbicide selections depend upon what type of grass or weed you have growing. Dallisgrass is often confused with field paspalum and thin paspalum, some other frustrating grassy weeds. While all three resemble each other, there are difference dallisgrass has which differentiates from the others. If you are unsure whether the plant is dallisgrass or not, send a photo to us at identification@solutionsstores.com and we will properly ID the plant for you as well as give you the proper product recommendations and tips on how to kill dallisgrass.


Step 2: Inspection - Once you have properly identified the grass as dallisgrass, you will need to inspect your lawn to see how big of an invasion do you have. You wouldn’t want to do a full-blown chemical application if you only have a small outbreak. For a larger outbreak it would be wiser to engage in chemical control. Determine the size of the infestation and where it is concentrated and then you can move onto step 3.


Step 3: Control - There are two herbicides which work best with eliminating dallisgrass. The best product is MSMA. Several applications of MSMA can be applied on 5- to 7-day intervals during the summer when the plant is actively growing. Aside from this, we recommend Glyphosate. Use a pump sprayer for the most precise spray pattern and try your best not to get the product on your desired grass. Some other options include Revolver (combined with MSMA for long-term control).


Step 4: Prevention - Dallisgrass is a perennial plant so there is little that can be done to completely and totally prevent the grass from coming back. However what helps your chances in keeping dallisgrass away is by making sure your yard is healthy and densely planted with turf. Dallis grass is known to be persistent and will grow on bare areas if not managed right away. Overseed bare areas to prevent dallisgrass seeds from germinating. Leaving no room for dallisgrass to germinate will surely kill the unwanted weeds. Moreover, lawn mowers used to mow dallisgrass should be cleaned to eliminate seeds that may be left clinging on the mower.

Learn More About Dallisgrass

Dallisgrass (Paspalum dilatatum Poir.) is a perennial grass which appears during warm-seasons. Native to the South American countries of Uruguay and Argentina, the plant was introduced to the United States in the late 1800s. It was named dallisgrass after a Georgia farmer named A.T. Dallis who was a big supporter of the plant and brought it onto his pastures. Little did  know that his name would be attached to a hated invasive weed which drives landowners crazy with how hard it is to control.

Dallisgrass can be identified by it distinguishing clump which gradually grows in a circular fashion. Unlike most grasses which grow in clumps and bunches, dallisgrass stands out due to their short rhizomes that increase the diameter of the plant and store carbohydrates. The way this weed grows makes controlling it frustratingly hard as the grass may avoid being chopped down by a lawn more and they can be hard to pull out of the grass because of the thick and fibrous roots which can reach down to 1 meter deep in the soil.


Dallisgrass is a ruthless invasive weed, and if you're not persistent with trying to control it, this unsightly grassy weed will become the turf grass of your nightmares.

So why does dallisgrass take over? There can be a couple of plausible theories. For one, soil compaction can be a factor. If there is a lot of foot traffic, your desired grass could get beat down while dallisgrass may thrive in the same conditions.

Dallisgrass is a troublesome perennial, meaning that it will come back from its roots year after year. It’s the cockroach of the lawn weed world. Dallisgrass invades all types of turf grass — Bermuda, St. Augustine, zoysia, buffalograss. They’re all unable to withstand its assault.

Controlling dallisgrass as soon as you notice it on your lawn is crucial because every dallisgrass seed is fertile. It does not require pollination. Keep the seed heads mowed off frequently, even if you have to mow every four days.

Dallisgrass Control Options and Tips

You have two options in controlling dallisgrass. One choice is to dig it out manually with a lawn tool such as sharpshooter spade. It's important to pull out the entire root mass. It will be dense and disk-shaped, usually in the top 6 inches of soil. If you leave even a sliver of the root system behind, the clump will re-form and dallisgrass will be back again

Aside from this you can apply a glyphosate-based herbicide to each clump. Use a pump sprayer for the most precise spray pattern. While glyphosate is a "kill all" herbicide and will leave you with a dead spot in your “good” grass, but it will grow in from the sides. A neat trick which can minimize the size of the dead spot by using a 1-gallon milk carton with the bottom cut out. Push the carton down over the dallisgrass. Insert your spray wand into the top, and let the bottle be the shield against spray drift.

 If you watch things very closely coming out of the winter, most years there will be a short window of several days where the dallisgrass has begun greening up and before your permanent lawn grass has started to follow suit. You may be able to spot-treat with the glyphosate at that point and gain good ground in eliminating it.

Finally, it needs to be noted that because dallisgrass is a perennial weed, pre-emergent weedkillers will not offer effective control because it comes back from its roots.
