    Anybody know the best way to get rid of Bermuda and CrabGrass without killing the lawn. The lawn is St. Augustine.

    Thanks

    Drive 75 for the crabgrass, Fusilade II IF it's labeled for residentual lawns in your state for the bermuda!

    not too familiar with warm season grasses. PBI Gordon (chemical company I believe in Kansas City, MO) has a product called Ornamec that is used for elimination of Bermuda Grass. May want to look them up and research this product.

    Ornamec is NR for use in residential turf. The active ingredient is Fluazifop-p, which is the same ingredient in Fusilade II. Fluazifop will stress St.Augustine.


    I have used Ornamec before in beds. It kills out Bermuda completely usually with one application,BUT it takes several weeks to die out. It does stop growth within 48 hours and is rainfast in 1 hour.

    Would atrazine work on the bermuda? St. Augustine is tolerant to atrazine, but bermuda has intermediate tolerance.

    Atrazine is primarily a broadleaf herbicide (but St Aug safe). Hence, its not going to be much use on crabgrass. I have used Manor for bahigrass in centipede with good success and it took out the crabgrass and goosegrass too. I recommend you contact your Dept of Agriculture's county extention office

    Fvstringpicker,

    I was wondering if atrazine would eliminate bermuda, not crabgrass, growing in St. Augustine.

    Have you tried using Vantage on centipede to get rid of bahia? I have been using Manor also.

    I've used atrizine as a broadleaf herbicide. I don't think it's going to be much use controlling bermuda. I've got good results no behiagrass in St Augustine and centipede with Manor. Thusfar, I've never used Vantage since Manor has worked well.
