Fantastic product! Lawns are how I make my living, and this product just became my new #1 in broadleaf control and grassy weed surpression (not large crab). TIP: use the lowest label rate per 1,000 ft2 and adjust from there.
I've been using this on my fescue/rye/KBG lawn and it's been great. I've gotten my dandelions and plantain under control. I also added some triclopyr to the mix to attack wild violet. The 2DQ definitely had an effect on the crabgrass but that's going to be an ongoing battle for awhile. Overall very happy with this product. I did use a surfactant with it.
