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.
