BioAdvanced 704080A All-In-One Lawn Weed & Crabgrass Killer, Ready to Spray, 32 oz (Packaging may vary)

For this, and all other herbicides - you need to use it at the right time of the season to get good effects. It will kill crabgrass and many broad leaf weeds but you will need multiple applications if you don't pick the right time of year.Check your local university extension and do some reading online to find out when would be best to apply for your area and the weeds you have.Also, make sure you apply properly. You need to go over your area twice, going perpendicular to the first pass on the second. After half of the area you're doing, stop. Check the bottle. You should have used 1/4th of it. Speed up or slow down to correct if need be. When you've done the whole area the first time you'll have 1/2 of the bottle left. Finish applying but go perpendicular to the first pass - example, if you went north to south first, go east to west the second time. Doing it this way will give you a chance to hit any spots you missed the first time. True, the weeds you miss on one pass will only get a "half dose" the second time around, but it's better than nothing.Also make sure to apply at the right temps, and not too soon after or before rain.Read the directions carefully and apply correctly and at the right time and you will get good results.

There is no way that one bottle could treat 2500 sf. I have used this twice and working quickly was barely able to cover 1200 sf each time. May have to try this at half throttle?The product is effective against crabgrass. Give it 2 weeks to work.

This product absolutely kills all the crabgrass and others (read the label) without harming grass and bushes. You can see results in a few days, those limping browning annoying crabgrass, eventually withers away.

It works to kill weeds and grass between slates and the edges cement near growing grass.

Might as well be water*Update: it did manage to kill the lawn grass!

I bought this specifically to kill over the dreade spotted spurge weed. I sprayed this on the weeds and within hours you could see them start to dry up and die. My new go to product for weed control.

Easy to use - no fuss or mess. The sprayer works fine

This product was used to remove weeds from my Bermuda grass lawn. You have to be patient it took over three weeks before I started seeing results Works as described I will be using this product to keep my yard under control
