14 best crabgrass sprays

Crabgrass sprays are herbicidal products designed to control or eliminate crabgrass, a common and persistent weed that can invade lawns and garden areas. Here's what you need to know about crabgrass sprays:

  1. Crabgrass Identification: Crabgrass is an annual weed that typically germinates in the spring and grows rapidly during the warm summer months. It has a distinctive appearance with wide, flat blades and can quickly take over a lawn if left unchecked.

  2. Selective vs. Non-Selective: Crabgrass sprays come in two main types: selective and non-selective. Selective crabgrass sprays target crabgrass specifically and are designed to spare desirable grasses in your lawn. Non-selective sprays, on the other hand, will kill most plants they come into contact with, including both crabgrass and desirable grasses.

  3. Pre-Emergent vs. Post-Emergent: Some crabgrass sprays are pre-emergent, meaning they prevent crabgrass seeds from germinating in the first place. These are typically applied in early spring before crabgrass has a chance to grow. Post-emergent sprays are used after crabgrass has already grown and are designed to kill existing plants.

  4. Active Ingredients: Crabgrass sprays contain various active ingredients, with common ones including dithiopyr, pendimethalin, and quinclorac for pre-emergent control, and ingredients like fenoxaprop-p-ethyl and mesotrione for post-emergent control.Always check the label for the specific active ingredient.

  5. Application: Proper application is crucial for effective crabgrass control. Follow the instructions on the product label regarding timing, dosage, and method of application. Some sprays come in ready-to-use form, while others require dilution and use with a sprayer.

  6. Safety Precautions: When using crabgrass sprays, it's important to take safety precautions. Wear appropriate protective gear, such as gloves and safety goggles, and avoid spraying on windy days to prevent drift onto desirable plants. Keep children and pets away from treated areas until they are dry.

  7. Timing: Timing is critical when using crabgrass sprays. Apply pre-emergent sprays in early spring before soil temperatures rise to the level where crabgrass seeds germinate. Post-emergent sprays are typically used when crabgrass is actively growing but still young.

  8. Reseeding: If you have to use a non-selective crabgrass spray in a lawn with desirable grasses, you may need to reseed or overseed the affected areas once the crabgrass is eliminated to promote grass regrowth.

  9. Persistence: Crabgrass can be persistent, and multiple applications over several seasons may be necessary to achieve complete control. Consistency in weed management practices is key to keeping crabgrass at bay.

  10. Alternative Control Methods: In addition to chemical sprays, cultural practices such as proper lawn maintenance (mowing, watering, and fertilizing), and maintaining a healthy, dense lawn can help prevent crabgrass infestations.

In summary, crabgrass sprays are useful tools for controlling crabgrass in lawns and gardens. Select the appropriate type (selective or non-selective) and application method (pre-emergent or post-emergent) based on your specific needs and follow safety precautions to ensure effective and safe weed control.

User questions & answers

Question: Will it kill Johnson grass and Dallas grass
Answer: It will not kill Dallis grass
Question: We have a 2600 sqft lawn and a 4 gallon backpack commercial sprayer. How much drive, water and surfactant should we add to the sprayer
Answer: I bought 1/2 gallon of XLR8 for probably 10,000 sf of lawn. I used 2 ounces per gallon + 1 teaspoon or so of surfactant on actively growing crabgrass in a bermuda and fescue central Arkansas lawn this summer. I spot treated the crabgrass, which had taken over probably 25% of the lawn and small patches of it in throughout. I've hit newly sprouted crabgrass or areas that I missed or that survived several times a couple weeks apart, and almost all of the crabgrass is dead. I still have more than 1/2 left. I don't think you would need to spray more than 1/4 of your tank at a time for 2600 sf, I would think 1/2 gallon would last you several years.
Question: What is the shelf life of this product
Answer: 3 years
Question: What is the mixing ratio for the 1/2 gallon and how big area it will cover, and how many times do have to apply. Thank you
Answer: Correction to my previous answer to your question: I mix 3oz Drive in 2+ gallons water and apply to 2000+ square feet, not 1000 as stated. This approximates the recommended (maximum) application rate for Bermudagrass of 1.45oz/1000 sqft. Another suggestion is to use 1oz per generous gallon of water per 1000sqft so you could use 3 applications (3oz per year per 1000sqft) and not exceed the manufacturer's limit of 2.9oz per 1000 sqft per year.

Answer: This is a very good weed killer. It is designed to most plants other than grass. Follow manufacture's recommended directions concerning application strength and surrounding plant life.
Question: Can i spray the lawn to kill crabgrass and reseed the lawn in 2 weeks time
Answer: I have used Ortho Weed B Gone on Crabgrass and it is a tough fight. It does seem to work quickly on broad leaf much better. On Crabgrass it may require multiple applications. I prefer an application of Scotts fertilizer w/HALTS in the spring. Doing this I get some Crabgrass but generally only around the edges. I use a 1 gallon pump spray so I can apply multiple times. For a whole lawn, wow
Question: What is the strength of 2-4-D in this?? is it more hand spectricide. weed stop
Answer: I would not recommend buying this product from Amazon until they start using a picture of the actual bottle that has the real front panel showing the concentration and list of ingredients.

User questions & answers

Question: Does this kill flowers
Answer: Yes! That small strap attaches using a metal bracket, which can be removed. Doing this can cause the strap to slide around on your shoulder. I would not recommend returning the product unless you don’t like it. I personally love this strap and use it regularly.
Question: Does this kill dollar weed or nutsedges
Answer: Hello, thank you for your inquiry, we will look into adding more photos. You can see multiple photos of this strap on our website at: http://www.blackrapid.com/Sport-Breathe
Question: How long do I need to wait from after I spray to mowing my grass
Answer: I lost it already, came here 4 months after buying the strap looking for these kind of complaints. I've used it less than 10 times and already lost it, when it's attached there's no problems, however you unclip it on the front and in the back the metal hook has an open design and is actually undone pretty easily... it fell off walking on a trail where I unstrapped it from the front. There's a new design with a closed clip design that solves this, however it's overpriced for a foot of fabric and two clips ($19).
Question: How long until kids can play on treated areas
Answer: It fits on the back of my IPhone with plenty of room to spare.

Question: How much do I use for crabgrass
Answer: This stuff contains Quinclorac which is the same stuff we used commercially with good results. The thing about crabgrass, (or any undesirable grasses), is they take a long time to kill. You can up the dosage but take the risk of killing the good grass as well. When Crabgrass starts to die, it first turns colors or red, purple or orange. It will not disappear completely like dandelions or any broadleaf. However it will not come back the next year. That said, this Quinclorac does not prevent any new seeds from sprouting which is what you might have had. Crabgrass puts out a tremendous amount of seeds each year if not killed early enough. (They only spread by seeds and all of it dies at the first frost. ) The key is to hit it hard and often early when it first sprouts before it goes to seed. Any weed seeds can last up to 5 years in the soil before they germinate depending on the soil moisture and temperature. This is why you may see new weeds when you disturb the soil in any way. A lush thick lawn will keep the soil temps down and many seeds will rot before germinating. This is why crabgrass and other weeds tend to sprout next to driveways, etc. because the temps are higher. A neglected, (problem) lawn can take 3-4 years of constant attention to become weed free. Your first application in the spring should be a strong fert with pre-emergent. This will kill off any seeds, (including grass seeds), that try to germinate. Pre-emergent lasts about 90 days. As the temps get hotter, back off on the fert, (unless you water in between the raindrops), and spot treat weeds as needed. No need to weed control the whole lawn as this is a waste. In the fall as temps drop and rain comes back, step up the fert and weed killer again. If you plan to spread new seed wait until fall. The temps are lower, there is usually more rain, the pre-emergent is done, and traffic on the lawn is mostly done. When reseeding, stay off the lawn as much as possible. No foot traffic, dogs, or weed control. I always told my customers to seed an area that they could cover with a few sprinklers and an automatic timer. Otherwise the seed won't take. Also, stay off the lawn when there is frost on it as you can kill the grass. Unfortunately, a very lush, thick lawn is fairly expensive as it can require a lot of water and or chemicals. A full sun lawn requires much more water than a shaded lawn, but recovers from damage quicker. The best lawns I have seen had an underground sprinkler system and had a good, timed lawn care service. Once we got the weeds under control in such a lawn, they required little, if any, weed killer.

User questions & answers

Question: will it damage shrubs and flowers
Answer: Keep the spray away from any type of ornamental flowers or Shrubs. It is made for lawn weed control only, not flower beds. You may try using preen granules around your flower beds. If you use colored mulch around those flowers and shrubs you will help control the weed population and enhance the beauty of the shrubs and flowers. Hope this helps. Steve
