Review: It did the job well-used all as directed - I used it according to the directions in the evening with the recommended Southern Ag Methylated Seed Oil (MSO) Surfactant and Liquid Harvest Lazer Blue - 8 Ounces - Concentrated Spray Pattern Indicator, Weed Dye, Herbicide Dye, Fertilizer Marking Dye, Turf Mark and Blue Herbicide Marker. The pics are day 4 and my grass is fine. My midwest acerage has always had a nice lawn but I slacked off for a couple seasons and a little crabgrass turned into a crazy amount this season. I had switched to a liquid applicator instead of broadcast and am finding it a lot more difficult than planned to get what i always just grabbed in bags before. I can see a few spots here and there that I missed so I'll touch them up in round 2 but the blue dye helped vusually to make sure I got 98% of it the first time. I was a little low on daylight and learned I had more crabgrass than I realized once I was I got going. I highly recommend not cheaping out to save a couple bucks on the Surfactant especially. Otherwise the spray will just fall off the leaves or ball up in big drops and roll off to the ground (surface tension) and you will not achieve a desired result.
Review: War on Crabgrass, I won! - Works better than anything else that I have tried on Crabgrass! I mixed 4 Oz with 2 gallons of water, added two tables spoons of Dawn dish soap and spot sprayed with my 2-gallon hand sprayer. I could see each crabgrass plant, so I did not need any dye to see what I was spraying. 3 days later, crabgrass is dying, lawn grass is untouched and a week later the crabgrass plants rot! No need to pull them up or disturb the other grasses. I'm now crabgrass free!

Thanks for considering using Keystone Pest Solutions to purchase this product!

**Q: does it work on zoysia grass without damaging the zoysia?**
A: The instructions say yes which is why I purchased it.  Just. completed the first application last week and you can see the torpedo grass turning yellow and no damage to the zoysiia grass.  This product requires multiple treatments (every 14 days) until torpedo grass is dead so will see how the remaining treatments work.

**Q: The instructions say "for use in new york state by spot treatment only". can it not be used elsewhere?**
A: It can be used elsewhere. States dictate how a product can be used in their state. Those instructions apply to New York. New York cannot broadcast spray. They can only spot spray. Please read and follow all label instructions. Thank you.

**Q: can this product be mixed with other weed killers ?**
A: Quinclorac can be mixed with other herbicides, but you need to review all product labels to determine mixing order and compatibility.  Also, be sure to use Methylated Seed Oil (MSO) as a surfactant when using Quinclorac.  Be sure the other herbicides allow MSO as a surfactant.

### ⭐⭐⭐⭐⭐ The crab grass is now toast!
*by E***5 on September 6, 2018*

Heck ya! This knocked out my crab grass in one shot! I applied late August with crab grass being very will developed in my lawn. It was applied with some MSO as a surfactant and oh my, crab grass was showing some serious signs of death in the first 24 hrs, less than one week later and the crab grass is toast, completely brown and shriveled starting to wilt into compost! I will give it another week and will overseed, the label says seeding is ok within 7-10 days of application. I could not be happier with how this performed.
