    Well Guys:
    I'm in trouble--Another clients wants me to do the impossible--I need help. The yard is full of Green Kyllinga (can be treated with Basagran), Dallisgrass--can be treated with Vantage and Dichondra (ponyfoot)-treated with Atrazine and three way.

    I have plenty of Atrazine and Three-way--never used any Basagran and Vantage.

    OK--question is what mix would be in a cocktail to treat all of these in a CENTIPEDE YARD????? Yard is about 7500 sf.

    Dallisgrass could be spotted with Roundup which still leaves a problem with the Dichondra

    Any help from Southern Turf guys????

    Thanks,
    Roy

    Certainty is labeled for control of Kyllinga and can be used on Centipede. The good news is you can use Certainty for lots of other things as well. Such as Fescue and Poa removal from Bermuda/Zoysia and Nutsedge control on most warm season turf. I don't think it would sit on your shelf unused.

    Too bad you have Dallisgrass, that is a pain under any circumstance. No choice but Vantage there.

    Dichondra can be controlled with Atrazine or a 3-way mix, but not with a single app. Some formulations of 3-way are not labeled for Centipede depending on the percentages of 2,4-d. Trimec Southern is one that you can use.

    I would mix basagran w/ manor or blade for most broadleaf weeds and dicondra (I found that basagran alone does nothing). For quick results for broadleaf weed control, mix manor/blade w/ quicksilver or octane. Sedgehammer works alright for green kyllinga. When was that centipede grass lawn put down? In the FL area, those don't survive too long due to ring nematodes and ground pearls.

    This yard has been down for years--I've advised the guy on leveling and replacing the sod, which he has done. He put in his irrigation. Now he wants me to help on the weeds. It's a hard yard to manage as it is partically in shade, has some St. Augustine, bare spots, and on and on. What about Atrazine and Basagran. Ric has a cocktail of this for his Bermudagrass in Fl. St. Augustine and centipede are so picky. He's a neighbor and old. His road fontage is pure sand without any irrigation. Any ideas there? I was thinking of that mulch and Bermudagrass.
    Thanks,

    Correction I work mostly with St Augustine turf. The Basagram and Atrazine cocktail is used on St Augustine. Atrazine is not recommend on Bermuda. My area is too hot for Centipede so I can't help you there.

    BTW My own yard 5 acres is mostly Bahia and Bermuda. I chemically mow it with Roundup every 6 weeks and have no weeds. I only cut it every 6 weeks in the rainy season right before I chemically mow it. Chemical mowing with Roundup is best done with a well calibrated low volume boom sprayer. The trick is in the calibration.

    Ric:
    Most of the chems that refer to St. Augustine are the same for Centipede with exception to amt. that is used. They both grow from stolons. Is there something other than the gene pool of the plants that i should know about? What would you use for that Green Kyllinga, yellow sedge(Sand spurs) and Dichoranda (Wild geranium type of stuff--low growing on the ground) I have Atrazine, Image, Sedgehammer, Southern Speedzone, Southern Ag's Weed Killer with Trimec--formulated for Centipede and St. Augustine (10% Mecaprop) and Basagran. I was thinking of using the Trimec (Dichondra) with the Basagran (Sedges) at the lower limits. Or, two applications: One with Image for the sedges and Trimec for the Dichondra.

    Sledge Hammer or Image should take care of Killinga, Sedge, Dichoranda and Sandspurs.

    The ""(Wild geranium type of stuff--low growing on the ground)"" I would try a thing a bob with a do hickey on it.

    It's been many moons ago when I last worked in a St. Augustine market but Dichondra was always a pain then. Unable to spray it with Trimec unless the turf was completely dormant as I recall but could be wrong...hell I thought Roger Clemens was done LOL.

    Veg: There's a lot of vacant lots and centipede on county roads in SC. I'm going to put my chemistry to work and come up with some cocktails of Sedgehammer and Atrazine for a test, some image(Imaquine) and Sedgehammer (Halosulfone) using the lowest of recommended use and just try. These guys that I'm helping aren't paying me. They're neightbors and they will buy what chems I need. I just brings my medium tanks and sprayer and piddle. But I'll get the correct mix. I just don't want to wind up with a bunch of useless stuff. I have Atrazine, Sedgehammer, Basagran, Trimec Classic, Southern Ags. Trimec. here in Tennessee. I bought some image and the neightbors are just glad to have someone to help them out without costing an arm and a leg (gas prices). There's only 5 now 6 neighbors that really care about their yard. I'm sure that Trimec would kill the St. Augustine and Centipede. Atraziine is #1 choice of many. I'm working with the County Extention Agent who is willing to supply some sample bottles, provided I give them a written report on findings. Hell, that's nothing--I've done that for 40 years.
    Anyway, Thanks for the heads up on the Trimec
