Purchased this to get rid of nutgrass and crabgrass since I had a problem with both in my yard. I applied at the minimum rate (10 oz/acre) for application on Bermuda grass. Seemed to work great on the nutgrass. Was turning brown in a week. But not so good on the crabgrass. Crabgrass was my biggest problem. If I had applied at maximum rate (14 oz/acre), it may have done better, but I have 1.5 acres and this stuff is super expensive. One bottle was barely enough to treat my yard one time. Seems to be a good product, but super expensive for the results I got on the crabgrass. I used a 20 gallon pull behind sprayer for application.
