Dallisgrass can be quite difficult to control and usually you can’t get rid of it without digging it out of your lawn. While that doesn’t seem so bad, if you have a lot of dallisgrass which has developed on your lawn (which is highly likely because this weed is known to spread over an entire lawn in rapid fashion) it would take a lot of work to remove all the dallisgrass.

Dallisgrass Background Information

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.

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.
