    Its May and I still have alot of brown spots in my bermuda.I have alot of green but alot of brown,about 50-50.I wouldnt think this would cause it but figured I would ask anyways.
    Feb 1st I sprayed a premergent myself,well I started working in landscape with a company that has a Spray division.Well one of the purks for working with this company is all the employess get free spray service IF they want it.Of course I jumped all over it.About the end of Feb they sprayed my lawn with Stage 1 which also happened to be a premergent also.Could this be the reason why ive got a half brown lawn?

    Im in North Ga.I dont have a sprikler system but I water it every other day.

    Thanks in advance

    With out knowing what was sprayed - your quess is as good as any one else's here.
    Actually obtain the active ingredient sprayed, not the trade or local name, amount AI in the tank, then ask the question again.
    As a general response, No - preemergent herbicide will not "kill" Bermudagrass, just stunt it a bit.

    I we only use granular Pre-Emergent and if it is not watered in there is a good chance of some burn. If the Pre-M is over applied or mixed wrong there could be some burn.

    It needs to be fertilized now to get the growth moving. If the turf has not been mowed down (scalped) it will also take longer to greenup.

    Preemergent herbicides (barricade, pendi, dimension) should not cause visible problems with your turf. But if it has been overapplied your root system could be stunted or damaged. This also depends on what preemergent was applied. Hopefully it wasn't Simazine, because it can delay greenup if applied too late. It is not normally used except during the dormant season.

    Also if you sprayed a postemergent during the greenup time, that can also slow things down.

    Yes applying phenoxy herbicides to Bermuda in transition can delay green-up especially if it was a Ester formulation. Ask the guy that sprayed what was in the tank but as far as the turf being permanently damaged I doubt it. We are talking about toughest grass on this planet right?
