By attacking weeds to their very roots, the problem is dealt with completely. This prevents the issue from recurring. At the same time, this herbicide doesn't harm any other vegetation on the lawn if users follow instructions. 

Since newcomers might have a hard time administering it, manufacturers have also come up with a solution to the problem. Spraying is easier than ever, and one just has to attach the hose to the bottle and start applying it. Due to this, covering large areas quickly is a piece of cake. 

Finally, the ability to remain resistant to rain for around an hour ensures that this herbicide doesn't get washed away too quickly. The longer it remains in the soil, the more you'll see its effectiveness increase significantly. 

What Could've Been Better? 

While this herbicide is effective for other weeds after just one application, it takes considerably longer to tackle crabgrass. Users have found that it needs three to four sittings to handle the situation. Although the current version is concentrated, manufacturers might decide to improve the strength of this BioAdvanced herbicide in order to improve its functioning time. 


  • Highly effective against crabgrass and other weeds
  • Easy to apply
  • Multiple uses
  • Remains for a longer time


  • Takes longer to kill crabgrass

Ease of use is another major factor working in this product’s favor. This item can be used to cover large areas in a very small amount of time. All one has to do is attach a hose to the bottle and start spraying. 

Since it kills pesky vegetation right down to the roots, there is no fear of them returning. At the same time, you can be sure one application of Ortho's product is enough to tackle the problem. Besides, the weed killer also stays on for a long time because it is resistant to a certain amount of rainfall. 

What Could've Been Better? 

Users have noted how the hose spraying system works wonders. But, sometimes, the build is not strong enough, resulting in parts breaking a little while after the hose is attached. Due to this, buyers find it difficult to keep using the product. By improving the quality of the materials used, this problem could be easily tackled. 


  • Acts quickly
  • Easy to apply
  • Multiple functions

Why Did We Like It? 

A lot of items work best in preventing crabgrass from returning, while others merely kill the existing crabgrass but do nothing for the future. When you rely on the Tenacity herbicide, you can automatically use it during both stages of the problem. 

If it is used while the crabgrass is growing, you'll see it attacking the roots and eliminating the intrusion. At the same time, it also prevents further seeding. The problem with crabgrass is that seeds spread, and so does the weed. By stopping this process, the herbicide effectively resolves any problem. 

Naturally, this herbicide also targets other problems, which increases areas of application. Crabgrass is not the only weed this item takes care of. Apart from all the benefits listed, the shelf life is great too. Tenacity Turf Herbicide can be stored and used for five to eight years after it has been manufactured if it is stored in proper conditions. 

What Could've Been Better? 

There's no doubt about the overall effectiveness of this herbicide, but it does not act fast. Users have noted that about a week elapses before it shows any impact on weeds. By making it act faster, manufacturers could ensure that the problem is addressed much quicker. 

Due to the slow nature of work, this item can't be used if the situation is dire and the crabgrass needs immediate culling. 


  • Works during and after crabgrass growth
  • Easy to apply
  • It lasts for a long time
  • Highly effective functioning


  • It takes a long time before it starts functioning effectively

When you go with Primesource, automatically, areas of application increase. This herbicide is mixed in a manner that makes it suitable for turf, which is commercial, as well as non-commercial. Some users prefer heightened effectiveness; in which case, it should be combined with seed oil that is methylated.

Finally, this is an item you can rely on and choose every time you want to get the job done quickly with the best results. 

What Could've Been Better? 

For the most effective use, this herbicide has to be applied repeatedly. Naturally, some users expect a concentrated formula that'll take effect after a single round of use.

On top of that, the BASF herbicide is water-based, so spraying it is incredibly easy. A single bottle can service an acre too, which is why several users prefer to buy this item. Cost-effectiveness is an obvious edge in this case. 

While most herbicides take time to dry up, increasing their chances of being washed up, this BASF item dries up in under an hour, ensuring faster absorption. If you want effectiveness to be even more heightened, then opt to use this product along with Microyl oil replacement treatments. 

Treating weeds with this herbicide ensures that they won't return again, which is what makes it a top choice for numerous customers.

Top Crabgrass Killers and Preventers Buyer's Guide

Buying Guide For The Best Crabgrass Killers and Preventers

Now that you're familiar with some best crabgrass killers, you have to decide on the one that suits your lawn the most. There are several factors to be taken into account. 

  1. Time of Action 

When you're choosing the herbicide, you should consider how long it takes to act. Some variants can take up to two or three weeks, while others begin functioning under 24 hours. Of course, considering this, you have to understand what kind of application you're looking for. 

If crabgrass infestations require immediate addressing, then choose the quick-acting options. But, if you want a more permanent solution, then opt for variants that require more time but attack the roots. 

  1. Ease of Application 

Plenty of newcomers get into gardening and must use such herbicides to maintain their lawns. Thus, the ease of application becomes a major swaying factor while choosing the right product. Several options on the market come with sprayers, many of which are battery-powered. 

Of course, when a measurer is included, and there are clear instructions on the label, then using it becomes even easier. 

  1. Area Covered 

Since herbicides can be rather pricey, a lot of buyers check how much area a single canister can cover. There are several options with highly concentrated formulae that can be diluted with water and then spread over a large area. 

Notably, these are preferable to variants where the area covered is less. Those with large properties inevitably end up spending a fortune to treat their lawns in such cases. 

  1. Nature of Formula 

The nature of the solution plays a big part in the effectiveness of the herbicide. There are several items that use strong chemicals and work very quickly. But, if you prefer longer-lasting and more environmentally friendly options, then you should choose those with natural ingredients. 

At the same time, there are variants that work in conjunction with other products for a more holistic treatment. Similarly, there are some which can be used solely for all-around protection. 

  1. Price

Pricing is a very important issue irrespective of what you're buying. Some of the better quality products tend to be expensive. While they function more effectively, newcomers might shy away from said items. 

Of course, some manufacturers have money-back guarantees in place to assure users their investments are secure.
