There is no real permanent control. You may suppress Bermuda grass or think you have it eradicated but in most cases it will return. What makes control so difficult is the growth habits of the plant. It spreads quickly by under ground stems (rhizomes) and above ground stems (stolons). Hand removal - such as pulling and hoeing the plant - often makes it more difficult to manage by stimulating new growing points.
Chemical control is the only solution for Bermuda grass suppression. Contact your local Extension office for specific chemical recommendations. Be sure to read and follow product label instructions before applying.
Think about starting your spray program around Aug. 1 (Zones 6-7) in lawn areas where Bermuda is to be eradicated and new grass seeded. Once Bermuda grass appears to be dead, thoroughly water the area and try to stimulate any remaining active Bermuda. If needed, apply chemical control again. Then, reseed the area with the desired cool-season grass around mid-September.
