Spectracide ® Weed Stop ® for Lawns plus Crabgrass Killer Concentrate Ready-to-Spray 2.4 5 19 19
Only thing that worked for my lawn I had tried several different brands of weed killer as the previous owners of my home did not maintain the lawn. After three years of trying other brands, a year and a half of applications with this product has made my lawn the focal point of the neighborhood. I was spot applicating one night last week and some people walking by mentioned I should be spraying the lawn next door instead of mine. May 14, 2012
Spectracide weed stop Prior to using this product I had many people ask me what I did to make my lawn so green. After I used it they asked me what happened to my pretty lawn. This stuff darn neer destroyed my lawn. When I called the 1-800-917-5438 listed I could not get anyone to answer the phone. May 7, 2012
It works! It worked for some stubborn clover I had. They dried up after a couple weeks. We had a gloomy week after I applied it otherwise I am sure it would have been quicker. May 5, 2012
this product doesn't work I sprayed my lawn with the concentrate as per the instructions and it didn't hardly even wilt anything, so I increased the dosage and it still didn't do anything. Now all the dandelions have seeded and I'll have a bigger problem. May 2, 2012
Easy to use...but didn't work Seriously, the weeds look even healthier than when I applied the weed killer. I feel like I wasted my money and my time. The product was easy to attach to my hose, and it did dispense (used the entire bottle up). So for that, I will give the 1 star. April 30, 2012
killed all of our flowers next to the lawn Did not kill the weeds but it did kill all of my wifes flowers next to the lawn..... April 25, 2012
Did nothing but nourish the weeds!! This product did nothing for the weeds in my lawn but make them look better!! My wife even said that the weeds look better than the lawn does now!!! Horrible product! Not even sure why they still sell it?! April 25, 2012
Best weed killer on the market, and priced right! I typically use Spectracide Weed Stop+Crabgrass killer every spring on the lawn to kill/control the broadleaf and grassy weed types. This stuff kills the broadleaf weeds very quickly, while it takes a few weeks to really control hard to kill grassy weeds, like crabgrass. After a treatment of this product and within a few weeks, my lawn typically looks just like those other yards in the neighborhood that use the expensive lawn spraying services, that do not kill weeds any better than the Spectracide does, in my opinion. Why pay a lawn company big bucks to kill weeds when a bottle of this product does the same thing and takes 20 minutes to apply. My neighbor uses one of the most expensive lawn companies in the area and the Spectracide killed my weeds just as effectively as his very pricey lawn service. I choose Spectracide over the other major weed killer brands because it contains a separate chemical that controls sedges (sulfentrazone I believe). If you read labels, the others do not control sedge weeds. I really appreciate that this company includes this in the product, however, the tradeoff is less 2,4D and other chemicals than the other choices, but I have found that this is acceptable and really does not affect product performance. The only drawback I have seen with this product is that is has a hard time killing or controlling the annual bluegrass grassy weeds, i.e. poa anna and crabgrass killing takes a while. Overall, I highly recommend this product for all you do it yourselfers out there that take pride in doing the lawn yourself, and saving a bunch of money over having it professionally treated. I hope this product remains available for a long time to come! Thanks Spectracide for making my lawn regimen easier!! April 23, 2012

Answer: 
Chet, this product should not be used on St. Augustinegrass, but you can use Spectracide Weed Stop for Lawns for St. Augustine & Centipede Lawns Concentrate on that grass variety. Here's a link to that product: http://www.spectracide.com/Products....

Answer: 
It can be used now, but it will probably be more effective if you wait a little while longer. This product is best used when daytime temperatures are between 45 degrees and 90 degrees.

Yes, but it may cause temporary yellowing or discoloration on Bermudagrass, but you can expect a full recovery. Don't apply to your Bermuda lawn when daytime temperatures are above 85°F.

I had my lawn Core Aerated and then I spread about 15 pounds of grass seed with my Drop Spreader. It has now been 1 week and the yard has been watered generously. I have many weeds which need to be addresses with your product. How soon can I make an application without harming the efforts in Over Seeding?

Answer: 
For newly seeded areas (including overseeded areas), wait about six weeks after seedling emergence to apply, or four weeks after seedling emergence on Kentucky bluegrass, fine fescue blend and perennial ryegrass lawns.
