Highly effective at controlling Japanese Stiltgrass which had overwhelmed my back yard. Now the Stiltgrass is brown and fading away. Not good for Bermudagrass. Awkward applicator requires attachment to garden hose. Spray is wide and not adjustable. I wouldn't recommend this product if your area has much other vegetation that you do not wish to treat because controlling the spray is difficult.
for me the product worked great on most of my yard, there were patches that were too overrun by crabgrass that I wished I would have bought more than one bottle, it took a bit longer than other products I have tried but it was worth the wait, I should have bought and applied it earlier in the season
