how long does it take to kill the bent grass

I don't have any bent grass, but lots of other bad stuff...but 2-3 wks seems to be the cycle. And you can respray after 21 days if you do an overall spray.

2 weeks, give or take, and may require a second application. I just head into the yard every 2 or 3 weeks to re-treat and hit the ones I missed last time. I'm sure by fall it will all be gone.

Michael,From my experience each application kills an estimated 95 % of what was visible just prior to the application. The problem are the seeds in the ground that germinate later. This is why the manufacture recommends 3 applications with about 3 weeks between each. The dead bent grass can take more than a month to decay to the point the white color is no longer apparent. Overall, I would estimate it takes 12-14 weeks to obtain a good looking lawn when the starting point is extensive bent-grass. Bob

Approximately 10-21 days. When it starts turning white, you will know it is dying back. You will definitely need more than one application for Bentgrass, and I would recommend 3 applications that are 2-3 weeks apart. The following year I would reapply, or spot treat, to hit any areas where stolons or seeds re-emerged.

Hi. Like for all weeds that tenacity affects, it does so by interfering with the production of chlorophyll. Bent grass will start turning white (from lack of the green chlorophyll) after 7-10 days. It will die out two to three weeks after that. You may need a second application, but wait at least 2-3 weeks after initial application.

It kills everything, even grass. I add 1/4 dishwashing liquid and 2 TBS salt. Apply with a sprayer when the sun is out and it's hot.

hello . the way this stuff works is all broad leaf plants have a tiny cup at the very bottom of the leaf cluster , water and nutrients puddle there and are absorbed by the plant . and a grass is a straight shoot no puddle there . so when you spray the active weed killer drips into the puddle , the plant drinks , and BAM dead weed or flower oops . this type of herbicide has a fairly short lifespan (normaly a 3 to 6 days depending on rain) whereas weedkiller like roundup is super sticky and has heavier molecules , so it sticks to everything and stays alot longer (depending on rain 4 to 8 weeks) so yes this will murder you flowers . and it's fun to be a farmer . hello . the way this stuff works is all broad leaf plants have a tiny cup at the very bottom of the leaf cluster , water and nutrients puddle there and are absorbed by the plant . and a grass is a straight shoot no puddle there . so when you spray the active weed killer drips into the puddle , the plant drinks , and BAM dead weed or flower oops . this type of herbicide has a fairly short lifespan (normaly a 3 to 6 days depending on rain) whereas weedkiller like roundup is super sticky and has heavier molecules , so it sticks to everything and stays alot longer (depending on rain 4 to 8... » Read More hello . the way this stuff works is all broad leaf plants have a tiny cup at the very bottom of the leaf cluster , water and nutrients puddle there and are absorbed by the plant . and a grass is a straight shoot no puddle there . so when you spray the active weed killer drips into the puddle , the plant drinks , and BAM dead weed or flower oops . this type of herbicide has a fairly short lifespan (normaly a 3 to 6 days depending on rain) whereas weedkiller like roundup is super sticky and has heavier molecules , so it sticks to everything and stays alot longer (depending on rain 4 to 8 weeks) so yes this will murder you flowers . and it's fun to be a farmer . « Show Less

I don't know exactly. It depends what you're trying to kill and what you're trying to preserve. I can tell you that I was trying to eliminate a persistent creeping weed from my lawn and mixed the concentrate stronger than recommended on the directions. The result was killed weeds and killed lawn. It's taken some time for the lawn to return after much hard work but the weeds seem to be gone for good. I suggest following the directions and try a stronger dose two weeks later if the initial application does not work.

Technically I do not know - It works really well as long as you mix according to the instructions - Killed all the weeds and did not touch the lawn. I waited three weeks and then used it again to kill what came up since the first treatment. I typically will use it now as the only plants growing inn the lawn right now are the weeds.

It is the best grass seed I've used . I prepped the dirt with fertilizer . And seeded 2 time what the recommend amount. water 3 times a day at 15 to 20 minutes a day for 3 weeks ,I put a new seed fertilizer down at 3 weeks. I also do not cut my grass short , My cut length is about 3.5" long .And I bag all my clippings.My neighbors cut shorter and their lawn look brown in late July till fall.If your looking for a good quality seed use this seed..

I tried to kill grass with Burnout II and it didn't work!!!!!!! Sorry but I can not answer your question.

It should. It kills anything in the grass family. The product info is on their website. It has to be applied when grass is actively growing.

I use it to kill everything that grows on the road next to my curb. I find after a few days it starts to work and within the week, they are gone (grass and weeds). I usually have to do it twice a season in CT.

My problem with bentgrass comes, not from aeration, but from the wind depositing the seeds. You need to be after the stuff all the time and it spreads so quickly if not addressed. Theoretically, aeration could provide more advantageous sites for the seeds to fall and germinate, but it is also critical to your lawn's success. I would stay with the aeration, just go after the bent grass on a normal basis.

No, it will kill all but the very hardiest plant. Now, I do put it directly on some particularly nasty weeds in my yard. It will kill them, and then the grass eventually grows back.

No it does not kill the grass. It works well and the only problem I had is that it only lasts for a short time as it kills them but doesn't last long.

rack out the old dead grass. Best time to add seed after it is mowed and yes it will crowd out the weeds

have tried this 2x. did not kill entire yard, seeds took temporarily. the grass later died or diapeared & the weeds came back or a bald spot appeared. in other sections of yard had almost 1/2 yard cleared, all that hapened after temp.growth was the ST AUGUSTINE & BERMUDA pushed out new grass. my guess is that your yard has 2 be as bald as the MOON!

It killed mine in the southeast region. It kills a lot of weeds, but not the grass. My grass looks great as it is able to fill in without all the weeds taking over. It even appears to be more green after usage. 1 bottle has lasted me 2 summers so far. Great product! I will buy again!

Never put on my lawn. Look at the nuts edge and when it pulls up with no root have at it buddy-usually 2 weeks ;)

We wait until the brown vegetation rots completely and we see the dirt. At that point we throw down grass seed. Works great!
