    I treated some Yellow Sedge and Green Kliinga last week in SC following all recommendation on instructions: had my neighbor NOT MOW yard two days before treatment, NO water for 24 hours, used mix within 4 hours and now waiting out the 2-3 days after treatment to mow.
    QUESTION: What will be the evidence that the Sedgehammer is working? Will it yellow, wilt, droop? I'm not down there, friend will call tomorrow to tell me about his lawn. Since I've never used it, I don't know what to recognize. Thank God we don't have that stuff in TN where it mostly fescue and Trimmec, Speedzone and hard work.
    Would appreciate you help,
    Thanks,
    Roy

    Did you use a sticker? Should wilt and turn yellow and wilt. Might need two apps but someone else may have more experience.

    Sure did use sticker, per directions. Centipede grass looks like crabgrass on steroids and St. Augustine is even bigger--I think it's the same strain somewhere in the genes of things.
    Thanks,

    I will Ditto Honda Gull Wings posts. Give it at least two weeks before you get up set and think it is not working.

    Used Basagran years ago (worked fine). Then switched to Manage (worked fine too). Switched to Sledgehammer last year (worked just as well).

    I normally see yellowing of nutsedge within 5 to 7 days.

    Most efficient kill = spray when it's as tall as possible, use a fine mist, spreader/stickers are good, but not necessary, do not mow or water for 2 or 3 days. Repeat app might be necessary for the little ones that did not absorb enough product. The homeowner may have to "mow around" the area so as not to interfere with "a good kill".

    Thanks Harley, americanlawn, Ric and others. Would a followup application of Basagran (I have that on hand) be advisable in a month or so? He turned the irrigation back on after a full day. Hopefully that was OK?. Directions recomme nded no rain for 3-6 hours I told my neighbor that I would tell him when to mow. There were places were the green kliinga (fragrant) was like a beautiful grass. It was high (6") and I did a fine mist and covered it well even sticking the wand close to the center of some of the larger tuffs
    I once treated the fences of some baseball fields with my favorite Crossbow. It did not react quickly but after a week, things went quicker than any Roundup made. Neighbor will call with a report tomorrow (5 days after treatment) If it works, it will be the best $15 he ever spent. I got a chicken dinner. Thanks again--especially Ric for his advice and guidance.

    I used it when it was called "Manage". Nothing happens at first--maybe it gets slightly more yellow. Then the customer mows--and it generally does not come back after mowing--what remains slowly turns brown.

    Thanks Riggs-- I was wondering because the label stated that it only "Surpresses Green Kliinga" I'm back in TN. and advising him via phone. Can you believe that...Hey, he used to live here too. Thanks again

    Turf Grass Weeds are classed in 3 categories. Broadleafs, Grassy Weeds, and SEDGES.

    Basagram is what we might refer to as OLD Chemistry and Sledge Hammer (Manage) might be New Chemistry. Certainly could be called Newer Chemistry, But I have not used Certainty as yet and can not speak from Experience about it. I do hear it is a great product.

    Understanding how Sledge or any pests life cycle run helps us better control or suppress it. To Suppress a pest is to lower it's population. To control a pest is to lower it's population to the point of being able to tolerate that pest. Note That I didn't say total kill because today we no longer Exterminate. I am not going to open Pandora's Box here. Nuff Said.

    Like Blue grass which grows from Rhizomes, Sedge grows from NUTLETS under ground and are connected in long chains of Nutlets. Well established Sedge might have 30 Nutlet Chains under ground. Manage which is a systemic will only kill back 3 Nutlets, leaving a long chain of Nutlets to emerge as Sedge leaves. Basagram will kill back only one Nutlet and is in fact considered a contact not a systemic.

    It is your call if you want to retreat with Basagram. The population of the Sedge before and after Treatment would be the deciding factor.

    Ric,
    I have been using Image from Home Depot this year on nut grass and have been impressed with the quick yellowing. Do you have any experience with this product. It seems very cost effective if it does the job.
