So I've got a bunch of numblewill in my own yard and I'm wondering how to get around the ol' glyphosate it all and reseed in fall. Is there any hope in trying to seed it and reseed it and reseed it, and hopefully choke out the nimblewill with new grass plants? Or is it a glyphosate and start totally over again? I would really like to at least have some green as opposed to go through a season with a RoundUp'd yard all year. Any experience with this specific weed would help.

I haven't had to deal with this weed much so far, so any advice is much appreciated.

Multiple apps of imprelis would be the way to go - it might keep the nimblewill at bay and keep it dormant. As long as you are growing fescue or BG the imprelis should keep most other weeds at bay and they say tests have shown it also 'helps' supress bermuda and crab. But it is by no means a total pre for CG but will supress it if you use 4 oz per acre every 60 days.

tenacity will kill nimblewill with 1 application.

Tenacity is the best way to go assuming the labeling allows for treatment where you would like to apply it. Last I knew they were close to having it labeled for home lawn use. But, they have been close for a couple years. I have been told you need more than one application via a Turf Seminar ar Purdue. As I recall it was three apps a couple weeks apart in the fall did the trick. I wouldn't go by that as always read the label and talk to your distributor or other source with more info than me!

I have one lawn where we killed it off and reseeded. It will be back this year so I am also hoping to use Tenacity on it.

If noweedshere used it once and got results than that is even better.

1. imprelis is an endocrine disrupter, endocrine disrupters disrupt the endocrine system, they are poisons

2. do not treat near or on anything that animals may eat, like deer walking through your yard and munching on your turf

3. it is extremely toxic to fish

4. do not apply near any water

5. you will smoke your shrubs and trees with imprelis

6. do not apply near annuals

7. DO NOT support du pont, they have enough money and have killed enough people

7. ARE YOU F' ING CRAZY

Apply IMPRELIS™ herbicide in a manner that will avoid contacting nearby susceptible crops or other desirable plants with spray droplets. Applications must be made only when the risk of spray drift is at a minimum. Very small quantities of spray, which may not be visible, may seriously injure susceptible plants including ornamental trees and shrubs. Do not apply when the wind will carry spray mist toward susceptible crops or ornamental plants. Maintain a 25-foot buffer around non-target aquatic areas and between the point of direct application and the closest downwind edge of non-target terrestrial areas. Apply only using nozzles which will deliver coarse or greater (VMD >250 microns) droplets as defined by ASABE S572 standard. Do not apply with a nozzle height greater than 4 feet above the ground or crop canopy. Do not apply when wind speed is greater than 10 mph. Do not apply during a temperature inversion Do not apply to any ornamental bed.
• Do not apply this product directly to, or allow spray drift to come in contact with, ornamental groundcovers, foliage plants, flowers, trees, shrubs, nearby crop plants or other desirable plants; or to the soil where potentially sensitive plants will be planted during the same season.
• Do not exceed specified application rates for any area and particular care must be taken within the dripline of trees and shrubs or other ornamental plants.
• Do not apply where runoff or irrigation water may flow onto susceptible turfgrass, ornamental plants or crops as injury may result.
• Do not apply with a mist blower.
• Do not pour spray solutions near desirable plants.
• Do not use this product on golf course putting greens.
• Do not use grass clippings from treated areas for mulching or compost, or allow for collection to composting facilities. Grass clippings must either be left on the treated area, or, if allowed by local yard waste regulations, disposed of in the trash. Applicators must give verbal or written notice to property owner/property manager/residents to not use grass clippings from treated turf for mulch or compost.
• Do not seed, sod, sprig, or plug treated area with warm season turfgrasses until at least 60 days after application. • Do not apply to irrigation ditches or water used for irrigation or domestic purposes.
• Do not graze or feed forage, hay, or straw from treated areas to livestock.

Bill, I am afraid you are a small voice in the cacophony of praise surrounding Imprellis. In thread after thread on several forums, the advantages of Imprellis are being pronounced. I use very little broadleaf herbicide (spot spraying), probably one gallon of a typical herbicide for the entire season. And still, the cautions on the Imprellis label frighten me. I was wondering if it was an endocrine disrupter. Is there any herbicide that isn't?

I agree. The first thing that caught my eye is you can't bag clippings and add to your vegetable garden for 6 months after application. Yikes. I think I'd rather apply 2-4, D.

I think there are going to be a lot of dead trees and shrubs from this stuff, I am hearing drought stressed trees that come into contact with heritage get smoked. There are several companies from Texas that swear it has killed many of theirs, they won't use it anymore

all for a freak'n dandelion or clover

The spray drift of Imprellis sounds very potent. I can't imagine anybody using it as a blanket spray on lawns. (but they will)

At some of the educational sessions at CENTS, Imprellis was mentioned as the latest and greatest.

It seems clear by the label that you should not spray it inside the drip line of anything that you want to stay alive, if I just look in my neighborhood you almost could not use it at all as all of the trees are 30/40 years old and have drip lines that go across 90% of the lawns

At the NJ Turf Expo, Rutger's Scientist's presentation was a high recommendation of the effectiveness of Imprelis. Later I asked about concerns of water quality and detrimental effects on non-turf plants. He stated that was outside the parameters of their study.

Of course, we know that the university studies are completely independent and not affected by the source of the funding.

So, a couple things here before this thread gets too far off topic. 1) We have cool season turf here for the most part so Certainty is out. 2) From what the poster said about Imprelis was that nimblewill would need multiple apps and wouldn't actually kill it, it would simply keep it dormant, which isn't the option I like.

So, original question: Is the best way to eradicate nimblewill in a home lawn to nonselectively spray the affected area and reseed with appropriate measures?

I would still say Tenacity has the most promise. With it sending runners out so far you really need to kill off large portions of turf to really get rid of it.

IMHO:

1) Tenacity
2) Round-up and reseed

Ive had luck with just round up and reseeding. Obviously you cant spray it until its green.

Can't Bag clippings with Imprelis. Lol....... thats the best Organo-Joke Ive heard. Leaving the clippings in the lawn is the right answer for many reasons.

You can leave them on the lawn. Don't want to be removing any of that Imprellis even if it's on healthy grass blades.

I'm not sure if you caught my sarcasm about leaving the Imprelis on the lawn.
Thanks for pointing out the spelling of the product.

I have always physically removed nimblewill or "creeping bent grass". Luckily a recent freeze we had killed it way back where the lawn guy originally tracked it in when he was working in some beds.
