    What will kill liriope?

    I have a customer that wants several feet of this stuff killed dead. I've sprayed every herbicide I have over the top of it and it hasn't touched it, so when they asked me to do this, I had no idea what would do it. I'm looking for something that will do a one-spray kill. Anyone know?

    Roundup???

    Doesn't Roundup kill Liriope?

    If not, I don't know what's in it, but I've got some stuff called TVK Total Vegitation Killer and it kills everything. It's probably Gasoline, but it works.

    Scott,
    I've been spraying roundup over the top of monkey grass for a while now and it doesn't even phase it. Just keeps on trucking. What's that TVK that you've got?

    what is your application rate for roundup? i use r/u pro all the time and have no problem. you may want to try the new quick pro, supposedly it has a little more kick..

    Well, I went with a more cost-effective way, Sahara. I did discover that the label on the round-up type chemicals will allow a 10% solution ... I've been using about a 3%. Will let you all know how it goes.

    tell lesco you want a sample of r/u pro dry. they should have it in packets, this way you will save a ton by not having to buy 2.5gallon containers.

    CSRA,
    What kind of liriope are you trying to get rid of. Are these large specimens of dark green liriope or are they verigated liriope. Verigated liriope can tend to be a pain. Verigated liriope has white lines running through it. If they are just regular old dark green plants then unfortunately, pulling out the tap root is the best way to knock it out. If you really need to spray them, it would depend on what you have around them that you want to keep. You need to be careful because some products will drift taking out other plants later. Doubt this helps but let me know more and I can give you a better answer.

    This is a question I would love to have an answer to. I have had no luck with Roundup. Have had mixed results using Primatol mixed with kerosene. Hat to use it though as that mixture can cause a disaster if it gets anywhere you do not want it.

    IP,
    I considered the drift factor, you're right about that. Thing is, they're killing everything out there anyway ... it's the wildest thing I've seen in a while. This is the dark green swamp grass, not the variegated stuff. Will let you know the results.

    CSRA,
    Well if your not concerned with anything else than you might want to try Tordon RTU if you can find any. Thats a Dow product. You could also try Vegemec which is a PBI Gordon product. Pramatol is a good ground sterilent but like mentioned before, can drift as much as 15 feet from where you apply it. Good luck, let me know how it goes.

    a 15 foot drift? Wow.

    I applied some Sahara there but I don't think that I got good soil contact, since after a week there was no sign of it dying out. So last week I applied Prosecutor @10% w/sticker. Will see how that does.

    roundup/prosecutor/glyphosate based products are completely
    different from sahara or pramitol which are both soil sterilants.
    sahara and pramitol both drift and can prevent vegetative growth up to a year. glyphosate usually works in a week or two depending on concentration and combination of other chemicals like scythe or "quikpro".

    you never stated what is surrounding the liriope, whether its pavement or if there is turf or other plants around.

    if its a few feet, isn't it quicker to just dig out by hand?

    Yes, I'm familiar with the difference between sterilants and glyphosate but thanks for that review ... there is a problem with digging it out, besides it being outside of the contract and no extra money. Namely, there's about 150 to 200 fet of it, ranging from 6 inches wide to 5 feet wide, right in an iron fence. Me and my shovel went somewhere else!

    There were plants around this but they've all been removed by the HOA. Other than that, concrete sidewalk is there.

    I have both dark green and variegated liriope in my yard. The variegated is not a "runner" so it stays where you plant it....just bigger every year.

    The dark green is very aggressive and will spread quickly. I find it easy controlled with a roundup mixture of about double the normal 1.5 oz/gallon ( in other words, 3 oz./gal).

    It never seems like it's working for about 10 - 14 days then the plants yellow and die.

    Are you comfortable you are using a strong enough Roundup mixture and then giving it enough time?

    If so, you may have come across the varietal "liriopus kudzukus". It will eventually engulf the entire town so there's no hope!!

    Good Luck and let us know what finally gets it!.

    P.S. If you're not from the South, the Kudzu joke may not mean much....Sorry.

    Can you guys use Diquat? If you can, you may want to consider Reward with a 10% glyphosate spike for quick results.

    Historically, the glyphosate that I've sprayed OTT of liriope has been 3oz. per gallon, with surfactant, no change at all. Don't know yet about this 10% solution, it was raining on Thursday so I didn't go around to check it. Should know by Thurs.

    10% glyphosate didn't do much. Just a little color change at the tips, nothing else. Today we cut it down and re-sprayed Sahara, in an effort to get soil contact this time ....
