Best Herbicide Brands for Dallisgrass

There are many choices for herbicide brands in the market, but not all of them deliver promises of getting rid of pesky dallisgrass from your turf. If you’re looking for high-end brands with highly effective products to take care of your lawn for you, here are our top three favorites.


Quali-Pro is a top brand when it comes to post-patent formulations. They focus on innovation and provide a wide array of active ingredients ideal for professionals and everyone in the industry.

Roundup is a popular herbicide brand in the industry, mainly producing glyphosate-based solutions for all things that involve lawn care. It’s one of the most widely-used herbicide in the United States and many other countries for their broad-spectrum solution.

The brand started in the early 1970s and now, with nearly 50 years of experience in the industry, trusted and approved in over 160 different countries.

What to Consider When Buying Herbicides for Dallisgrass

The herbicides we listed and reviewed above effectively eliminate dallisgrass, but they have their advantages and drawbacks. That said, not all of them will be the best herbicide for dallisgrass in your yard. It’s why it’s essential to choose one that is ideal for your specific dallisgrass infestation problems.

Check out some important aspects that you need to consider in choosing the best herbicide for dallisgrass.

Preemergent vs. Post-emergent Herbicide

Not all herbicides are the same, and one of the first things you need to consider when buying one is whether you need a pre-emergent or a post-emergent herbicide. 

If you can already see dallisgrass infestation in your yard, then you need to get a post-emergent herbicide. It’s the type that can get rid of existing weeds and grasses. Meanwhile, if you want to prevent weeds from growing on the lawn, you need to use a pre-emergent herbicide. This weed killer type prevents germination of dallisgrass and other weeds, stopping them from infesting your turf before they can even grow.

Selective vs. Non-selective Herbicide

Another critical choice you have to make in choosing the best herbicide for dallisgrass is between a selective and a non-selective type. It will depend on your turf area or where you want to use the herbicide and your purpose for using it. If you only want to target the pesky dallisgrass in your garden, leaving the lawn and nearby vegetation, then a selective herbicide is best. Meanwhile, if you’re looking to eradicate any grass and weeds in the area, a non-selective herbicide can get rid of everything in its wake.

Contact vs. Systemic Herbicide

When choosing the best herbicide for dallisgrass for your yard, you also need to choose the ideal way to get rid of those weeds and grass. There are two options available, contact and a systemic herbicide.  

Contact herbicides get rid of weeds on impact, which means it can dry out and kill the parts of the plant that it comes in contact with. For instance, if you spray this kind of herbicide on the weeds, it will most likely only kill the leaves, leaving the roots intact. On the other hand, systemic herbicides force grass and weeds to absorb its chemicals for it to take effect. It’s the best way to kill dallisgrass from leaves to the roots, preventing any regrowth. 

Active Ingredient

Again, not all herbicides are the same, including the varying primary active ingredient they have. The effectiveness, selectivity, and rapid results of herbicides primarily depend on the chemicals they contain, making it essential to choose the ideal one for the job.

The most common active ingredient for many herbicides is Glyphosate. Many of them have Glyphosate as the primary ingredients, while others most often have it even at a tiny amount. Glyphosate is a non-selective and systemic herbicide, which means it can eliminate any plant in its wake. It’s one of the most effective ways to clear out an entire yard from unwanted grass and weeds. However, it’s a dangerous chemical to use if you have precious plants, trees, or shrubs nearby.

Another popular active ingredient on many herbicides is diquat, which is a fast-acting and contact herbicide. It gives you results in mere hours from application, although it only dries out the leaves and stems. It means that dallisgrass can still grow as their roots remained intact and undamaged.  

Some herbicides also have DithiopyrDithiopyr as an active ingredient. It is a pre-emergent herbicide, which means it’s most effective as a preventative measure before any grass or weeds grow. Herbicides containing this chemical are best applied before grasses start popping up during spring.

Another popular pre-emergent active ingredient in many herbicides is Prodiamine. Like Dithiopyr, Prodiamine herbicides are only best for getting rid of seedling dallisgrass. 


Coverage is another essential factor to consider when buying herbicides. However, it’s more than looking at the size of the package. You also need to check how much water you need to mix to the herbicide to work effectively. Some types are already diluted, and while they come in several ounces, they can only cover small spaces. Meanwhile, some tiny packages have a high concentration that only a small amount is needed to cover areas.


Most high-end weed killers will include “rainproof” in their set of specs and features. It describes the time that it takes for the herbicide to become rain resistant after application. Water and rain can dilute the chemicals you applied, so if it rains after you sprayed the herbicide, it can reduce its efficacy. That’s where a rainproof herbicide will work best, especially if you live in a moist or rainy area. 

Check out the rainproofing specs of the herbicide, if any. Some of them become rainproof 30 minutes to one hour after application, while others are fast-drying and only have ten minutes rainproofing period.

Formulation and Mixing/Usage Instruction

Lastly, you also need to check out the formulation and mixing and usage instruction of the herbicide you want to purchase. Some herbicides come in granulated or powdered form, while others are liquid that you need to dilute in water first before application. It’s also essential to follow the usage instruction of the herbicide to achieve the best results.


Dallisgrass is among the toughest weeds to deal with, especially once it established itself in your yard. It’s a known persistent perennial weed that resists frost and drought, growing in bare areas and returning each year. Fortunately, there are effective herbicides that can deal with pesky and unwanted weeds and grasses like dallisgrass. 

Our top favorite is the Dithiopyr-based pre-emergent herbicide from Quali-Pro. It’s a highly effective preventative measure to stop unwanted weeds from infesting the turf before they can even start growing. And while it’s a pre-emergent herbicide, the Quali-Pro Dithiopyr herbicide also offers early post-emergent control. 

However, no single herbicide is the perfect solution for all weed problems. Choosing the best herbicide for dallisgrass will depend on your purpose. A pre-emergent herbicide will help prevent new weeds from growing, while post-emergent herbicides tackle already growing or established dallisgrass. You also have to consider other factors like coverage, a systemic or contact herbicide, and the active ingredient used to choose the best herbicide for dallisgrass.

FAQs (Frequently Asked Questions)

Are herbicides safe for pets?

Weed killers that contain any kind of chemicals would be dangerous to children and pets. Walking through a freshly treated lawn using most herbicides is not advisable as it may cause some chronic health problems. However, some herbicide brands are safer for pets when using the product as the manufacturer advised, including the required drying time for the herbicide. 

Can my herbicide kill other grass on my lawn?

It primarily depends whether you are using a selective or non-selective herbicide. Selective herbicides will only kill weeds and grasses in its scope, leaving your turf and other plants safe. However, if you are using a non-selective herbicide, it will kill anything that comes into contact or cause it to burn.

How long do I have to wait for the herbicide to kill dallisgrass?

It depends on the herbicide type that you’re using on your dallisgrass infested lawn. In some cases, fast-acting herbicides will show results after a couple of hours from application. Meanwhile, some formulation may take a few short days to start showing signs or fully kill weeds. 

How many times do I need to apply herbicides?

It depends on the weed infestation in your lawn or garden. A single application can do the trick in minor cases, but other times when the weeds and grasses have taken over the area, respraying or reapplying herbicides may be necessary. Check out the manufacturer’s recommendation on your herbicide’s label to ensure product use and reapplication.
