Glyphosate didn't kill all my weeds

Palmer amaranth, an increasingly prevalent weed across the US, is often resistant to Glyphosate vegetation killer.  Before buying any do a little checking to see if your weeds are all killed by glyphosate-based weed killers.  Mine were not.

We purchased this Bayer weed killer on the recommendation of our neighbor, since his lawn looks great. It worked, but the process was very slow and required much patience.

Purchased late March as the grass and weeds were just getting going. Shook the bottle well, connected our hose and applied and even coat (as best as I could) to our grassy areas which total about 3000 sq feet. Did this by walking south to north, then crossing the yard again west to east. The application used about 1/2 of the bottle.

A few days went by and we noticed a little yellowing of the crabgrass and a decent kill of a few other larger, thorny type weeds. After about one week I put down another coat, applied in a similar manner, using up the balance of the container.

The second application seemed to really have an impact, and in a few days most of the other weeds were significantly withered away while there was at least a 50% crabgrass kill (light brown and dead).

At the same time I was putting down lawn fertilizer, and the grass really came in nicely without being impacted by the weed killer at all. Three weeks after the first week killer application, I began weekly grass cutting and the weeds and crabgrass have now gone away (everywhere except at the very edge of the lawn near the roadway, where some still lingers a bit).

Bottom line is that this Bayer weed killer product worked, but it took a long time and had to be applied a couple times in order to get the job done. But it did work... so if you are looking for a weed killer to act as I have described, and are willing to put down multiple applications, and have the patience of a saint -- then I'd recommend you give this stuff a try. It did not hurt our fescue based lawn at all, so that's a bonus.

Go for it.

I really like this stuff it doesn't kill everything but 95% of the weeds anyway, and most of the crab grass.
I had 3 teenagers walk by our house when I was trimming some bushes they said you have the nicest lawn on the street!

This is a fast acting weed killer.  We sprayed our gravel driveway in the evening when there was no wind, and in the morning all the weeds were clearly dying.  This will kill pretty much everything, so be sure to avoid overspray getting on anything you want.  Seems to be powerful and fast acting.

It didn't work at all. NO weeds died, not one. We followed the directions, waited the appropriate time, NO dead weeds.

I like it bercause it'is  safe to use but I found I needed to use a strong solution to get results. It also only seemed to worked on some of the weeds.

Bought this last July to kill thistle and grass in a drainage ditch.  Mixed up a heavy dose and sprayed as directed.  It had NO effect;  Even when some inadvertently spilled on the lawn, it had no effect.

I mixed this exactly as stated.  I sprayed the weeds direct once and nothing happened.  a few days later I repeated. nothing has happened.  the weather has been around 60-80/day, and it has been dry.  unless I hear from the seller about why it is not happening, I am totally not happy with it.

they say to use a small amount and add to water, but i use much more.  still takes about a week to totally kill weeds.  it works, but takes much longer than other weed killers.

We landscaped our front yard in 2009, a few months after moving into our newly constructed home, and ordered a full dump truck load of topsoil from a local landscaper to build up our natural areas.  It must have been full of nutsedge because the grassy weeds not only started appearing shortly thereafter, but they multipled like wildfire, and 3 years later I'm still struggling to get rid of the crazy infestation.  I've tried Round Up, which seemed to work at first, turning the grassy blades yellow, then brown.  But it didn't kill the numerous tubers at the root, and within a few weeks there were more weeds coming up than I originally killed.  I've tried pulling, but that obviously didn't work either, because for every weed I pulled out, there were 2 to 3 tubers still left underground that broke off of the main plant when I pulled it up.

I hate using chemicals of any kind to treat weeds.  I'm more of a pull them up as I see them kind of person.  But I was at my wit's end until I found this little green bottle.  Yes, it's expensive for the small quantity that you get, but it works.  I originally ordered 4 bottles, which covered about 90% of the weeds, and then had to order another 4 for a second treatment.  But at this point, $80 seems cheap for the results!  Two weeks after the first treatment, most of the nutsedge has turned brown and is dying.  I just came in from spraying a second treatment, and made sure to cover all new sprouts that have appeared since the first one.  My ornamental grasses, shrubs, and trees didn't seem to be affected at all by the overspray.  Although the dead yellow weeds are an eyesore in my front lawn, I'm not going to pull them up until I'm certain that all of the tubers are dead, which I estimate will take about a month, and maybe another 4 bottles to get any straggler sprouts that have yet to appear.

I didn't use the Ortho Max on an established yard, so I cannot comment on how well our centipede lawn would have resisted it, but I can definitely vouch for it's affect on nutsedge.  It has put a hurtin on it, and I now feel confident that by October I'll have eradicated it from my lawn permanently.  My only complaint is very minor.  Once I sprayed about 70% of the bottle's contents, I had to hold it straight up to get it to spray (as other customers have noted), which made it a little hard to angle it towards the weeds.  However, I quickly resolved the issue by just rotating the spray nozzle the other way to reposition the spray tube in the bottom of the bottle, and was able to angle it towards the weeds and empty every last drop, cursing the weeds as I sprayed.  Check out the customer images for my before and two weeks after first treatment pics to get an idea of how well it works.

Thank you Ortho Max!!

The grass took about a week to die, which is forever when you are waiting to rebuild the area. It did start looking sick right away, but not dead. It also came back through mulch in a few weeks. I may try something else the second dose

Not wanting to kill all my lawn i tried this. i used for 4 months, first month i used it at recomended rate, second month i doubled it, 3rd month i used 4x the amount, and finaly i used 8x the amount. The end result a full yard of bermudagrass, never did it ever show any sign that the bermudagrass was stressed. No reputable companly will claim they can remove bermudagrass unless it's a total vegitation killer. In fact they reconmend the stongest vegitaion killer allowed by law to kill bermudagrass. Save your money do not buy bayer products.

To fix my lawn i used total vegitaion killer, waited two weeks brought in 25 yards of high grade topsoil and then soded my lawn. I have a lawn that would make the golf course envy.

I am not a proponent of chemical solutions for the lawn but the clover in mine were laughing and cheerily breeding despite applications of corn gluten meal, so I tried Bonide's Chickweed, Clover and Oxalis killer.  I applied it in the backyard first when my dogs were away for boarding for a couple of days, mixing it in an approximation of the recommended amount (which I believe is 3.25 oz. per 2.5 gallon sprayer; I used 3 oz. in a 2 gallon sprayer).  After about a week a few of the clover patches had shriveled and turned yellowish, but the majority were still green and laughing at my efforts.  So for the front lawn I mixed 5 oz. per 2 gallons and absolutely DROWNED the clover.  This produced noticeable results, with many of the clover shriveling and turning yellow, and, more importantly, the flowers disappearing (to stop further spread).  So I will finish the side yard with that concentration ratio and hope for lasting results...

This product was not effective in completely killing nuisance plants on our high desert lot. Most plants died after the first pass, some on a second pass done one week later. But other plants survived both passes. I followed the easy to use instructions to ensure I was mixing the product as intended. I have had great success with other Roundup products.

I sprinkled on a liberal amount of Preen.  Les than 2 months later, my garden was covered in weeds.  I understand that this is designed to PREVENT weeds, but on a scale of 1-10, it 's about a 3.

Scotts Step 2 KILLS tall fescue grass. It helped marginally with dollar weed, maaaybe a little with dandelions, but it didn't even faze the other 15 varieties of weeds now filling in the huge dead holes in my yard where this stuff killed my grass. I used to use Scotts Bonus S before they changed the formula to something that doesn't work, and I was experimenting. I'm done with Scotts for all eternity.
