Bermuda grass is an invasive grass that can take over entire lawns over a period of two to three growing seasons. If you have a fescue lawn with Bermuda grass mixed in, you know how difficult it can be to kill only the Bermuda grass and leave the fescue intact. However, there is one product on the market that's specifically designed to kill only Bermuda grass and leave your fescue perfectly healthy and vigorous. Treatments should begin in the spring and will need to be continued throughout the growing season to completely eradicate all Bermuda grass.
Water your lawn to ensure the health of your fescue. Wait until the following day to apply Ornamec Bermuda-grass killer or another herbicide that has fenoxaprop or fluazifop and that's is designed to kill Bermuda grass without killing fescue—read the label carefully before purchasing.
Mix 1/2 oz. of Ornamec Bermuda-grass killer with 1/2 oz. of nonionic surfactant (available wherever Ornamec is sold and often included with Ornamec) in 1 gallon of water. Put this mixture into a sprayer and spray over 1,000 square feet of your lawn. This first spraying should take place around June 1, or right after the final frost of the season. Don't spray your lawn if rain is expected within 24 hours. If using a product other than Ornamec following label directions carefully.
Spray once again 30 days after your first spraying using a mixture of 3/4 oz. of Ornamec with 1/2 oz. of nonionic surfactant and 1 gallon of water per 1,000 square feet of lawn. Again, don't spray if rain is expected with 24 hours. Within three weeks, the Bermuda grass should begin to die. Expect a slight yellowing of your fescue, but this should clear up within 14 days. Follow all manufacturer's specifications if using a product other than Ornamec.
Spray a third time 60 days following your first spraying only if necessary (i.e., if the Bermuda grass has not died). Mix 1/4 oz. of Ornamec with 1/2 oz. of nonionic surfactant and 1 gallon of water per 1,000 square feet of lawn. Don't spray if rain is expected within the next 24 hours. If using a brand other than Ornamec follow the manufacturer's instructions.
