Prime Source Quintessential- Quinclorac with H-Value Technology for Increased Absorption- 7.5oz Bottle

These bottles lasted two years. Four applications each year. This is the only thing I have found to control crabgrass post emergence. My neighbor has a horrible lawn and he sprays all kinds of seeds and cuttings on my carefully maintained Zoysia every time he mows.

This project worked great, It killed the nutsage that was growing rapidly in our yard. I would highly recommend this product to anyone. I just lost a quarter of the product in shipping. It’s nice to receive the product in a bag floating in its own product. Luckily I was able to pour what was in the bag back into the container.

Works as advertised.

I should have listened to a friend who warmed me. quack grass is not crabgrass. supposedly there is no chemical that works on quack grass. it does knock it back a little, but does not totally kill it. rating is due to assumption that it works for intended purpose, just not mine.

I’m using this primarily for torpedo grass and some crab grass with 24D and methylatedseed oil. Seems to be working well after two applications. Will need more, but I expected that with torpedo grass.

Did the job on my crabgrass. Dead in 2-3 days after.

works as advertised

Didn’t work at all, applied two treatments on dandelion at back yard and it’s been two weeks and the weeds still not dead yet, don’t recommend
