Gordons Ornamec Over-The-Top Grass Herbicide is a selective post-emergent systemic herbicide that will provide excellent control over unwanted grasses in and around groundcovers, shrubs, trees, landscape beds, container yards and grower nursery fields. It’s a specially formulated liquid herbicide that uses Fluazifop-P-butyl as its active ingredient to help control unwanted annual grasses and perennial grasses, including panicum, crabgrass, goosegrass, foxtail, sandbur, barnyardgrass, bermudagrass, quackgrass, torpedograss, and johnsongrass. It also offers selective removal of bermudagrass without injury to tall fescue or zoysia turf. It can treat a majority of ornamentals on the label with “over-the-top” application. It may be used around newly-ermeging plants as well as transplants and it guarantees fast and efficient action. Comes with a 4 oz. bottle of surfactant.
Do not apply ORNAMEC herbicide if rainfall is expected within 1 hour.
ALWAYS ADD A NONIONIC SURFACTANT containing at least 75% surface wetting agent at 0.25% vol./vol. (8 fl. oz. per 25 gallons) of finished spray volume.

BERMUDAGRASS CONTROL IN ZOYSIAGRASS AND TALL FESCUE TURF:
ORNAMEC may also be used to suppress and eventually control some undesirable grasses in turf areas. To control common bermudagrass and hybrid bermudagrass, follow the directions below:
Bermudagrass Control in Zoysiagrass:
Late Spring: Apply 12 to 16 fluid ounces of this product per acre with a nonionic surfactant. This application should be made around June 1 and repeated at 28 to 30 days. For spot treatments use 0.3 fluid ounce (2 teaspoons) of this product and 0.3 fluid ounce (2 teaspoons) of nonionic surfactant in one gallon of water to treat 1,000 square feet.
Mid Summer:During hot summer weather use 16 to 20 fluid ounces of product per acre with a nonionic surfactant. For spot treatments use 0.4 fluid ounces (2.5 teaspoons) of this product and 0.3 fluid ounce (2 teaspoons) of nonionic surfactant in one gallon of water to treat 1,000 square feet. NOTE: The 20 fluid ounce rate could cause temporary turf discoloration.
Late Summer: When bermudagrass is preparing for dormancy use 8 to 12 fluid ounces of this product per acre with a nonionic surfactant. For spot treatments use 0.25 fluid ounces (1.5 teaspoons) of this product with 0.3 fluid ounce (2 teaspoons) of nonionic surfactant in one gallon of water to treat 1,000 square feet.
Bermudagrass Control in Tall Fescue:
Apply 20 to 24 fluid ounces of product per acre. For spot treatment use 0.5 fluid ounce (1 tablespoon) of this product with 0.3 fluid ounce (2 teaspoons) of nonionic surfactant in one gallon of water to treat 1,000 square feet. The first application should be made in early spring (April/May) when bermudagrass is breaking dormancy.The second application should be during September/October when bermudagrass is preparing for dormancy. Applications during the hot months of summer should be avoided.
NOTE: This application will show slight discoloration to desirable turfgrass. Desirable grasses should recover within 10 to 14 days. Weather and cultural treatments can also affect applications. Use a minimum spray volume of 30 gallons of water per acre.
Bought this to knock down bermuda in a tall fescue lawn. Very quick acting, very pleased.
On another note, shipment arrived having leaked out of bottle, through packaging, and the USPS had contained it in a plastic bag. I lost about 1/3 of the product. When I notofied DMOPC about it, they had another in shipment that same day, gratis. Very fine service, much appreciated.
Tried a couple of other products that did not work. Although this takes a few days to actually see it working, you can see the bermuda drying up and dying without hurting my zoysia grass. Great product. Applied as directed with gallon sprayer.
Used the product in my ornamental flower beds and boy! I'm so thrilled by the results of what I'm seeing, the grass is dying back and my ornamentals are doing superb! I cannot tell you how terrified I was to use this product at first: it has a very offensive odor when you open the bottle and to be honest this stuff intimidates me a bit...but boy did is it working! My only issues are the initial smell and the cost. It's exspensive...but I have to say it's worth the cost when I can use it in my flower beds without issue to my ornamentals. Thank you!
I measured off my yard according to directions and applied the chemical in 1000 sq ft areas as directions stated. I have a few areas where the Bermuda grass is dying but some areas look healthy and seem to be thriving. I'm waiting another week to see if anything starts to happen in those areas before I can be sure that the Oramec is working as expected. As expected, it has yellowed my fescue lawn, add drought conditions and high temperatures to that, my yard looks horrible now. If this will control the Bermuda grass, I'll live with that side affect until it starts raining again.

I have a 20 x 20 ft. approx area of Bermuda I tried to kill with Roundup. lokks like I need something more serious like this. How long is the shelf life on Ornamec?
According to the manufacturer, the shelf life on most liquid herbicides all depends on how they are stored. If the product has been tightly sealed and kept out of sunlight and extreme temperatures, the shelf life is 3-5 years.
Can I use Ornamec in an ornamental perennial garden?
I have a variety of perennials such as sun and daylilies, lucifer tongue, Luine, Shasta daisies, echinacea, chicks and hens, ornamental and asiatic lilies, and all sorts of hardy succulents, creeping and tall phlox, spiderwort, dianthus, Siberian iris and bearded iris uses, along with hostas. I'm having a very hard time getting rid of the grass that's growing in my beds and wanted to know if your product would be safe to use on these plants?
