Review: Works good. Needs reapplication for best result. - I buy this to fill up the sprayer from the same brand that goes to a hose. It does the mixing for you so you just pour it in there and go. I buy this to refill it since it is cheaper for the refill if you already have a sprayer. Or you can mix it with water and use it with a bug sprayer. You have to pull back the label to see the full directions. I have found that it works best if the lawn doesn't get rained on for a few days. Waiting for a dry day will make it have more bang for your buck. Also, it can really take out weeds but it takes several days before you will notice a big difference. I use it whenever I see weeds. Roughly about 4 times per year. My yard has got a lot better since I have been using this for about a decade. You want to put seed down a couple weeks before or after using this. Not at the same time. If you use it when it is too hot it can sort of burn the grass but it hasn't been an extreme problem. It won't kill the grass if you use it as directed. Some weeds it doesn't kill or takes more applications. When you apply it you don't have to do very much. Just spray it on there and wait a week. Then do it again. Putting too much on at once seems to make it not work as good. It also works better if you aerate right before you put it down so that it gets to the roots. Several applications is better than a lot at once. It is a good deal for the price. It works best when used right after cutting the grass.
Review: Good weed control - Works good on crabgrass. Works slow but is effective.

### ⭐⭐⭐⭐⭐ Good weed control
*by F***T on 9 May 2026*

Works good on crabgrass. Works slow but is effective.

### ⭐⭐⭐⭐⭐ Excellent Product & Lightning-Fast Delivery!
*by M***Y on 27 June 2026*

I ordered the Spectracide Weed Stop for Lawns Plus Crabgrass Killer Concentrate along with the Chapin G390 Hose-End Sprayer, and I was amazed—they arrived within an hour! I paid the $4.99 expedited delivery fee, and it was absolutely worth it because I wanted to treat my lawn the same day. The Chapin sprayer was easy to fill and use with the concentrate, and everything worked exactly as expected. Being able to order both items and start spraying my lawn immediately was a huge convenience. If you're looking for a good weed control solution and don't want to wait days for delivery, I highly recommend both the products and the fast delivery option. It saved me a trip to the store and let me get the job done right away.
