I have a newly started centipede lawn that's not fully established that just before dormant season I started getting Bermuda and crab grass.What would be a good weed control program for this centipede lawn to start this spring?Thanks for any suggestions.

Was the lawn seeded or sodded? If it were sodded I am surprised that there was bermuda in the sod. Other that a PROPER fertilization without chlorine based fertilizer. Centipede will not tolerate chlorine; it will actually poison it slowly. Water turf with every-other-day schedule of about 1/2" per cycle, and no pre-em until fall. Let me know before proceeding. Centipede is very picky and you can kill it before you realize it.
If you sodded, where did you get sod infested with bermuda and crabgrass? I'd complain and take some photos back to the sod farm. Bermuda in centipede is real bad news as almost anything that you put on centipede to control the bermuda will kill it. Crabgrass is no problem with established turf and sod. Generally a good pre-em will take care of that. There's a fantastic warm-seasoned guy (Greendoctor) from Hawaii that knows more about centipede than anyone and maybe he will give some insight on bermuda in your turf and are you sure it is bermuda instead of common crabgrass?
I used to live in Ocean Isle Beach and know that area very well. Been through Tabor City many times. Let me know what you do. Roy

Weed control? I would direct my efforts towards a program of turf management. Centipede needs an acidic, well drained soil that receives water regularly. Secondly, this is a grass that must not be cut short. I am thinking along the lines of 2"-3" and no shorter. Finally, due to the very shallow root system of centipede, I avoid the common preemergent herbicides. My weed control is to follow those cultural practices so the grass grows thick and vigorously. Weeds are controlled by herbicides that do not injure the grass or prune its roots. I will use simazine or atrazine as a preemegent. Gallery is also very good for stopping infestations of broadleaf weeds. Crabgrass and bermuda can be controlled by treatment with sethoxydim herbicide. To generalize my recommendations: centipede is never to be treated or fertilized like other cool or warm season grasses. Attempting to do so is a recipe for disappointment.

No the lawn was seeded with a drill my lawn is four acres I would have been broke if i would have laid it with sod.But anyway its done real well so far but i have some patches of bermuda in certain areas.Thanks a lot for the feed back Im still trying to learn as much as i can about turf management Im adding to my lawn care & landscaping service.I know a far amount about it but i like to see what others opinions are.

Yes. Especially in the areas away from the coast. Centipede is salt sensitive and does better on acidic soils, so it does poorly at sea level. I have to know how to maintain 5 different species of warm season grass here.

Come on man, you know better than this. :nono:

Interval water based on when you hit your MAD (management allowable depletion) with the amount necessary to bring the effective root zone (current + desired) back to field capacity (+ any leaching requirements).

Well, maybe a 1/3"+/- or so. These lawns get hit with 100 degrees plus almost daily in the summer and dry out extremely fast, couple that with almost pure sand that leaches within an hour after a rain then the extra water (.5") is a normal for coastal turf to keep the roots reasonable moist. Let them go for two full days and they curl or even close. Golf courses water every night on coastal grounds. Maybe in your part of the country with a different soil, an inch (1.0) is OK with infrequent and deep irrigation. Shallow wells are common for every home for irrigation, another difference and water is plentiful the wells have a endless source of water from the ocean lens purifying the water as it presses towards the coast. Centipede and St. Augustine are not drought tolerant as bermudagrass. Think what you will; however that every-other-day schedule has proven to be a key to a thick an vibrant lawn. You may have issues with monthly fertilization.
