Spectracide Weed Stop for Lawns Concentrate 32 Oz, Ready to Spray

It did the job as intended. Worked within hours. Killed my clovers and some yellow and purple little flowers that were attracting a lot of bees and even though I like bees it was getting dangerous for us and my dogs just to use the yard. Problem solved. I didn’t cut the grass before application to see if it really works; it did. Also it did not killed the good grass at all. If you see a lot of dead areas it means your lawn was just covered in weeds just like the review that left 1 star. It’s super easy to use. Don’t have to measure anything. Just hook your hose, shake -n- spray. I will be using it again in the fall.

Not as effective this round up, but it does work and it seems to be safer.. It just takes a longer time to kill off undesirable weeds… you have to reapply.

Works great if not very fast... you can add more ionic or nonionic surficants to shorten the activation time. Make sure to spray only spots that need treatment... and then soak them. AGAIN I will add about 1 tsp SLS (dishwashing detergent) to increase "Stickiness" of the product to problematic wide-leaf plants. Works in about 3 weeks, first withering seen in about 3-4 days.

Didn't kill anything, barely wilted a few weeds..I used an entire bottle on my 2.5-3k sq ft yard. Followed the instructions exactly. It had zero impact on crab grass. Other weeds were barely wilted. The only weeds it actually manage to kill was where I poured the concentrate directly without any water mixing just to see what would happen. In the same yard with the same conditions I had better results with Scott's Weed B gon - but still no where perfect. Scott's is more expensive and not really worth it either.

Marginally effective. Works on lesser weeds.
