Application Recommendations: Agralawn Crabgrass Killer works best when applied to wet grass/weed. You can wet the affected area with a hose, irrigation, spray bottle or apply immediately AFTER rain. Personally, I have found that applying the product first thing in the morning with the morning dew works the best. Think about it. The dew already covers the plant and is enough to wet and activate the product.  Apply only to the affected area being careful to dust all of the target weed this product is known to control. A light to medium coating applied in even strokes will work best. Noticeable results in 2 to 4 days. Do not apply if rain is forecasted for several days in a row or prior to watering the lawn to avoid washing away product. Reapply as needed. Do not use when turf is dormant or below 60 degrees.

 *** Please note that the YELLOW food coloring had to be removed from the product for registration purposes. The product will still turn a slight yellow from the Cumin. It will not be a bright yellow as in the past due to the removal of the food coloring. The YELLOW coloring was for a visual reference only and did not contribute to how the product works.

Top 4 Reasons to Use Agralawn Crabgrass Killer Completely safe because it's all-natural Safe around pets & children Easy to use selectively—sprinkle directly on weeds No long-term damage to surrounding growth

Questions and Answers

Q: Is it safe?

A: Yes; Agralawn Crabgrass Killer is safe around people, pets and the environment.

Q: How do I use it?

A: It's very easy; just wet the area you want to treat with water and sprinkle the crabgrass control over the area.

Q: How long does it take for the crabgrass to die?

A: Noticeable results will be seen in 3-5 Days.

Q: How big of an area will the bottle treat?

A: One 2 lb. bottle will treat 100-200 sq. ft., depending on the applicator.

Q: Will it kill the seeds?

A: No; it will only kill actively growing crabgrass and weeds.

Q: Will it hurt my grass?

A: Agralawn Crabgrass Killer will not harm St. Augustine, Bermuda or Bahia grasses. Other grasses are being tested throughout the country.

Q: What if it doesn’t work?

A: It will work; just make sure the area is wet enough and evenly treated. It’s very easy to use.

Q: What do you mean “wet enough” and why does it turn yellow?

A: The Agralawn Crabgrass Killer product turns yellow to let you know it has been fully activated. Water is the source of its activation so enough water is needed to activate the process.

Q: Why do I want it “activated"?

A: Within minutes of activation the product begins to kill the weeds.

Q: How can I best “activate” the product?

A: Wet the desired area, apply the crabgrass control and wait a few minutes. If not activated, then lightly mist over the product so as to completely activate. (Do not wash the product off of the weed’s leaves.) Q: How can I “wet the area?” A: Use a spray bottle, backpack sprayer, water hose or irrigation.

Q: How long should I “not disturb” the product after it turns yellow?

A: Leave the area undisturbed for 24 to 48 hours.

Q: What do you mean “undisturbed?"

A: This product is taken in through the weed’s leaves and will not be taken up through the root system. Irrigation, mowing and rain can disturb the product enough so as to reduce the desired results.

Q: What do you mean “evenly treated?”

A: You may think more is better, but piling this product on weeds will only cost you more. A nice, light to medium application is adequate, as long as activation was accomplished.

Q: Is it temperature sensitive?

A: No; in all of our years of testing Agralawn Crabgrass Killer has been 100% effective in all temperature zones in North America.

Q: Can I use it year round?

A: Yes; but applying it to weeds that are already dead or completely dormant would be a waste of product.

Q: Do you have any tips to help me save money on your product?

A: Yes. Remember to completely cover the area you want treated. Try and catch weeds at their smallest stage or simply mow them down to reduce the size and area you have to cover, reducing the amount of product you’ll need. Do not completely remove the weeds as the treatment must be absorbed by the leafy part of the weeds. Safe to Use On: St Augustine, Common Bermuda, Bahia, and Centipede Grasses. When used properly, this product will cause very little reation or yellowing to the above listed grass types. This product is taken in through the leaves to kill existing weed and roots.

    Great product to kill Crabgrass

    Posted by Frank Clark on Aug 9th 2023

    Initially purchased the small shaker of product from Amazon see how well it works. It really does work to kill crabgrass. I have now purchased the 25 lb bag and 4 lb shaker to tackle the vast amount of crabgrass that we have. I applied the product to an area in our front yard this morning and am seeing results this afternoon. It really does work. There are in my, however, 2 shortcomings on this product. First it is a powder, so a shaker of some sort is necessary to apply the product, and because it is a powder it needs to be applied when there is no wind, otherwise you'll have a lot of drift. Second, the method of application, using a shaker bottle, does not lend itself to large areas. We have a 1 acre lot and to try and cover the whole property with a shaker bottle is not practical. It is better used as a spot treatment. If Agralawn could put this product in granular form, I could load up my tow behind spreader and take care of our entire 1 acre in 30 minutes. Also know that this product only kills actively growing crabgrass and other listed weeds. It does nothing to prevent weed seeds from sprouting (the company is very upfront about that), so a pre-emergent is necessary as a follow-up to combat weed seeds from sprouting . All that being said, I will continue to purchase this product because it works. It is expensive, but it is organic so for me it's worth it.

    Agralawn Crabgrass Killer is a must!!

    Posted by Bill Ison on May 8th 2023

    I have used Agralawn Crabgrass Killer for at least the past 10 years. It controls nutgrass and wild strawberries quickly and completely. I use it in the flowerbeds and spend very little time having to pull weeds.

    Perfect Weed Killer for Lawns

    Posted by Ellen Aldrich on Aug 7th 2022

    This is a safe and effective way to treat crab grass and many other weeds found in St. Augustine turf. The second best thing is how safe it is for the turf, the earth, your pets and yourself. Worry free and it works!! I use it with the shaker. 25 pound bag is a good deal.

    the stuff works...

    Posted by Ron Kirn on Sep 6th 2021

    Yep. sprinkle it on and a few days later the Crabgrass is deader 'n Texas Roadkill... However on crabgrass it requires repeat applications to completely kill the weed... and a "normal" spreader will not work, it's just to powdery... I used a flour sifter....

    I have used this product in the past with excellent results. Truly works to rid crabgrass from my Augustine post emergence. Love the fact it's pet and people friendly with the scent of cinnamon. Will continue to purchase as long as my neighbors allow their crabgrass to flourish and seed.

    Kills Virginia Buttonweed!

    Posted by Cynthia Jones on Nov 6th 2020

    I’ve been at war with Virginia Buttonweed for years. Finally found something that stops it in it’s tracks, without killing the grass. And I love that this product is organic and safe to humans, animals and birds. Smells good, too! Completely satisfied.

    Death to Basketgrass

    Posted by Mark on Nov 3rd 2020

    I tried a 2 lb. can of this product on basketgrass in my lawn. Three days later the weed is dead and my St. Augustine is not. I love this product, so I bought a 25 lb. bag so I can kill some more.
