10 best crabgrass preventers

Crabgrass preventers are products used in lawn care and gardening to control the growth of crabgrass, a common and invasive weed that can quickly overtake lawns and other grassy areas. These products are specifically designed to inhibit the germination and growth of crabgrass seeds. Here's what you need to know about crabgrass preventers:

  1. Pre-Emergent Herbicide: Crabgrass preventers are a type of pre-emergent herbicide. Pre-emergent herbicides are applied to the soil before crabgrass seeds have a chance to germinate and establish themselves.

  2. Timing: Timing is crucial when using crabgrass preventers. They should be applied in the early spring, typically when soil temperatures reach a certain level, which varies by region. This timing helps create a barrier that prevents crabgrass seeds from sprouting.

  3. Mode of Action: Crabgrass preventers work by forming a chemical barrier in the soil that inhibits the growth of crabgrass roots. They do not typically kill existing crabgrass plants but rather prevent new ones from emerging.

  4. Selective vs. Non-Selective: Most crabgrass preventers are selective herbicides, which means they target specific types of weeds like crabgrass while leaving desirable grasses and plants unharmed. This selectivity is essential for maintaining a healthy lawn.

  5. Active Ingredients: Common active ingredients in crabgrass preventers include prodiamine, dithiopyr, and pendimethalin. Different products may use one or more of these ingredients, and effectiveness can vary based on the specific formulation.

  6. Application: Crabgrass preventers are typically applied in granular or liquid form. They should be spread evenly over the lawn and watered in to activate the product.Proper application is essential for effectiveness.

  7. Reapplication: Crabgrass preventers have a limited duration of effectiveness, usually several months. It's often necessary to reapply them later in the season or as recommended on the product label to provide continuous protection.

  8. Lawn Health: While crabgrass preventers are effective at controlling crabgrass, they should be used in conjunction with a comprehensive lawn care program that includes proper mowing, watering, and fertilization to maintain a healthy lawn.

  9. Safety and Environmental Considerations: It's essential to follow the manufacturer's instructions regarding application rates and safety precautions. Avoid overapplication, which can harm desirable grasses and plants. Some crabgrass preventers may have restrictions on use near water bodies to protect aquatic life.

  10. Weed Identification: Proper identification of crabgrass and other weeds in your lawn is essential for effective weed control. Knowing the type of weed you are dealing with will help you choose the right product and treatment.

Overall, crabgrass preventers are valuable tools in lawn care and can help homeowners maintain a weed-free, healthy lawn. However, it's essential to use them correctly and in conjunction with other lawn maintenance practices for the best results.

User questions & answers

Question: It is ok to put Weed and Feed after putting this product but before 30 days are over. Says at the back to wait for 30 days before another application
Answer: You would want to wait the entire time before applying another product with fertilizer. If you have broadleaf weeds now, you can spot treat with Ortho Weed B Gon.
Question: I just applied Crabgrass preventer. How long must i wait to lay down seed to grow grass
Answer: In what I’ve read before, 6-8 weeks. At that point you should wait until fall, which is there ideal grass time in most climates. It gives the grass a chance to start growing on top, then winterize and grow strong roots so that spring will be awesome. About 3 years now I’ve been applying this strategy and find my grass is greener than all the neighbors. There is one neighbor who has a thicker lawn but he has a different slope in his yard and has been at it much longer. I will overtake him!
Question: How soon can I throw down some new seed? I would like more kentucky blue in my lawn
Answer: you have created a force field. only way is to put down new loam 1/2'' thick then seed . late august aerate lawn then seed,& do it like your feeding the chicken & those hens are hungry. next year you will not believe, keep your deck clean & blades sharp. GOOD LUCK
Question: Okay to use in August
Answer: I have Poa Annua and have been doing a lot of research on it. Many websites with information about Poa Annua say for effective control, besides Spring treatment it is good to put pre emergent down in August/September. Here is a quote from the Purdue University Extension website: "Poa annua is a winter annual that germinates in the late summer/early fall once soil temperatures fall below 70o F. Seedlings mature in the fall, overwinter in a vegetative state, and flower and produce seed in late spring and early summer." I just chatted with Scott's website and they said this product can be effective when used in this manner. I plan to apply it then AND next Spring. Most of the lawns in my development have been taken over by Poa Annua but I am still fighting the fight and hope to win or at least keep it to a minimum.

Protect your lawn all season long against listed weeds, including crabgrass, all while feeding for a fast green-up after winter.

When To Apply To Prevent Weeds

Apply in early spring to prevent the germination of crabgrass, chickweed, poa annua, and other common lawn weeds, before they start to spread. Apply before the 3rd or 4th mowing to protect all season long.

Tips For Lawn Care Success

First, regular feedings help your lawn look it’s best and provide the nutrients it needs to withstand the stress of weeds, weather and activity. Secondly, after you mow leave the grass clippings on the lawn. This allows grass to use water more effectively. Finally water, utilize nature’s sprinkler as much as possible. When you do have to water, do it between 6 and 10 am - less water is lost to evaporation and more reaches the roots.

User questions & answers

Question: How often do you need to apply this treatment
Answer: As often as you want as long as you do not go over the maximum amount for your turf type per year. For some turf types, that is about .83 ounces by weight of this dry granule per 1,000 sq. ft. Most typically people apply this in the late winter or early spring. Many say to put this down when the soil temps are at 55 degrees in the winter/spring, but that is when crabgrass starts to germinate. Many lawn care professionals say to put this down earlier, when the temps are 40 to 45 degrees because it is the bacteria in the soil that break down the product and at these temperatures, the bacteria are pretty much dormant. You apply at 0.185 ounces by weight per 1,000 sq. ft. (for any grass type) and that will give you 3-4 months of protection when put down at those temps above. Put down 0.28 ounces per 1,000 sq. ft. to give 4 months of protection in the fall. I apply when the night time temperatures start dropping into the low 70's and upper 60's. I saw someone say you want this down before the soil temperatures drop to 70 in the late summer/early fall, but I have not confirmed this. So if the day temps are in the 80's and 90's and the night temps are in the 70's or upper 60's, you should still be ahead of the annual weeds you're trying to prevent in the fall.
Question: Is this product safe for centipede grass thats 1 year old
Answer: This should be safe on any established grass which typically means the grass has grown enough to be mowed 4+ times. You can put it down a little earlier depending on the grass type, but better safe than sorry. If you put this down too soon you can harm the new grass while it is maturing and if you do this, the prodiamine will stop new grass seed (as well as weeds) from germinating for a few months.
Question: Will it prevent crabgrass
Answer: Yes. Prodiamine is broken down by the microbes in the soil, and the microbes do not really start to become very active until the soil temperatures are higher...like 50+ degrees (not 100% positive of what temp here, but you get the idea). Crabgrass seeds start to germinate once the ground temperatures start to reach about 55 degrees. So you can put this down when the ground temperatures are 40-45 degrees and it will still be very effective once the ground temperatures reach ~55 degrees and provide the protection you need, versus waiting until the ground temps are already at 55 degrees and you may be too late. What this does it once the crabgrass and other seeds start to germinate, Prodiamine will stop the roots from progressing once the seeds start to germinate, which kills the plant before it completely germinates and breaks through the soil. What I like to do (heard this from a lawn care professional - YouTube channel 'Pest & Lawn Ginja') is get use a cheap meat thermometer and check the soil temps and once the ground temps are around 55 degrees, put down a different pre-emergent called Dithiopyr. This will also stop seeds from fully germinating as the Prodiamine does, but Dithiopyr also acts as a post-emergent for very young weeds and crabgrass up to 2-3 tillers. So you get early protection and a second layer of protection if required.
Question: will it work with no pre mixing sprayer connected to water hose? if so, is setting of 2tsp for one gallon will work
Answer: I wouldn't recommend it. Prodiamine, straight out of the container, is in granular form. Each granule is about 1 mm in diameter. All the hose end sprayers I know of require dispensing of the product as a liquid. For my application, which is to treat for Annual Bluegrass (Poa Annua) in a Zoysia lawn, I used a 3 gallon backpack tank sprayer. I measured 3/4 Tbsp. Prodiamine and poured it into a quart container. I then added 3 cups water and mixed the two together into a concentrate. I then poured the concentrate into the backpack tank sprayer and added water to make 3 gallons. 3 gallons will treat 750 sq. ft. The amount to use is 1/4 Tbsp. Prodiamine per gallon of water. Each gallon will treat 250 sq. ft.There are 3 tsp. in a Tbsp.

Pre-Emergent

This GreenView Fairway Formula spring lawn care product will prevent crabgrass and other undesirable annual grasses. The most effective way to control crabgrass is by applying a pre-emergent herbicide, commonly called a crabgrass preventer. It creates a barrier at the surface of the soil, disrupting normal crabgrass growth and controlling seedlings before they sprout.

Kills Broadleaf Weeds

Controls over 200 weeds, including dandelion, clover, chickweed, carpetweed, and many more. See Use Directions for Complete list of Treated Weeds.

Feeds Lawn for Up to 12 Weeks

This GreenView Fairway Formula spring lawn care product boasts the highest slow-release nitrogen content on the market. Our 65% slow-release nitrogen provides a steady delivery of nutrients that will be used by the lawn for up to 12 weeks, meaning more of the nutrients will be used by the plants and not washed away.
