BioAdvanced All-In-One Lawn Weed and Crabgrass Killer I, Concentrate, 40 oz

If you've ever battled bindweed then this product is your friend. Bindweed field are these vine-like nasties that grow in no time, root down several feet, crawl up every living thing, suck the life out of them and regrow faster than Robin William's beard. We have lost several trees to this vine--big ones that sometimes fall on our house and are taking over the rest of our trees. But this product kills it. The reason I'm so emphatic about this product is that it is a serious risk due to it's tendency to make all our trees fall on our house. And that's not even mentioning it's complete takeover of our yard and grass. The problem is it kills what you spray it on so quickly that it doesn't have time to get down into the roots and kill the source. So if you have Bindweed the best idea I've read is to ball the ends up and put it in buckets with diluted Bindweed killer so it will soak it up slowly. Even put some fertilizer in the solution so the weed will be motivated to soak it up. Lastly, be patient. Killing bindweed is a long-term project which will go a lot better with this product on your side. Oh yeah -- it kills every other weed I spray it on too.

Seems to have done to trick on killing crabb grass and other weeds. Effects take about 5 days to see with the slight yellowing of the grasss as it works its way to the root. I have cut my grass and there seems to be much less crabb grass and weeds growing back, hasn’t killed every weed but most of them and I have plenty still left in the bottle

I use this in a pump sprayer and it works well to kill dandelions, clover and crab grass. Dandelions start to shrivel in a couple of hours and rot away over the following days

My lawn was invaded by crabgrass this past spring. I applied this once and within a couple of weeks, no more crabgrass.

I bought this in July last year and thought I'd wait till this year to leave the review. I had a fair amount of creeping clover, loads of patches of crab grass and a few other odd weeds. This took a couple of weeks to arrive, however it did come from America, so be prepared for that. However it worked amazingly, a very small dose by comparison to other week killers you woukd use in the UK, after the first week the flowers on the clover has all died off, the leaves had withered and the thick vines were starting to shrivel up, the crabgrass looks half dead, as if it hasn't seen water for weeks, so I gave it a second going over with the weed killer, a week later literally all of the crabgrass had withered away and was dead, the clover was non existent as we're the other odd weeds, I was left with patchy grass where the crabgrass and weeds had been killed. All I needed to do was cut the grass very short, take the lawn rake over it to get all the dead stuff out and then over seed and water it in. Grass looked excellent after a month or so. However I thought I'd wait till spring this year to see if loads of crabgrass popped back up, and I am happy to say I had 3 patches, each about the size of a tea plate. So this has been great success.
