Gordons Ornamec Over-The-Top Grass Herbicide

Gordons Ornamec Over-The-Top Grass Herbicide is a selective post-emergent systemic herbicide that will provide an 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 such as panicum, crabgrass, goosegrass, foxtail, sandbur, barnyardgrass, bermudagrass, quackgrass, torpedograss and johnsongrass. It also offers selective removal of bermudagrass without injury to tall fescue and 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 mini bottle of surfactant.




APPLICATION DIRECTIONS:

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.

SPOT TREATMENTS TO CONTROL GRASS IN ORNAMENTALS, NURSERIES AND LANDSCAPING AREAS

Mix ORNAMEC and only a nonionic surfactant with water according to the amounts shown below. Spray to obtain thorough coverage, but do not spray to runoff. Re-treat if necessary.

ANNUAL AND PERENNIAL GRASS CONTROL RECOMMENDATIONS

  • Use 64 to 96 fl. oz. of ORNAMEC herbicide per acre and 0.25% vol./vol. (8 fl. oz. per 25 gallons) of a nonionic surfactant. For perennial grasses, use 96 fl. oz. of ORNAMEC per acre per application and three applications will be needed.
  • Spray to obtain thorough coverage of grass foliage, but not to runoff. Repeat treatments may be necessary to provide full season control.
  • Use standard pesticide hollow cone or flat fan nozzles.
  • Apply ORNAMEC herbicide to actively growing grasses before they exceed the recommended growth stages shown below.
  • Do not apply ORNAMEC herbicide to grasses which are stressed due to moisture, temperature, low soil fertility, mechanical or chemical injury.
  • Do not apply to grasses which have tillered, formed seedheads, or exceeded recommended growth stages.
  • Apply ORNAMEC herbicide when the first grass species in a mixed grass weed population reaches the recommended growth stage for treatment.

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.

    5 of 5 stars  Fine product, fine service
    By Tom in Waxhaw, NC on 09/15/2015

    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.

    By Dan in Sarasota, FL on 12/06/2015

    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.

    3 of 5 stars  Still waiting
    By Doug in Bristol, TN on 06/16/2016

    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.

  • 5 of 5 stars  Works Great
    By Philip in wimberley, texas on 10/13/2017

    I had some chickweed that had spread into an area where I wanted grass to spread. The grass could not crowd out the weeds. I used Ornamec in a 2 gallon sprayer with the surfactant that comes with it and a blue spray indicator. Withing a week the weeds were belly up and the grass can spread.

QI have a 1/3 acre yard with tall Fescue that has Bermuda mixed in. How would I mix this in a 2 gallon sprayer?

AIf you are wanting to control bermudagrass in tall Fescue grass, you will use 0.3 fl. oz. of Gordons Ornamec Over the Top Grass Herbicide and 0.3 fl. oz. of non-ionic surfactant in at least a gallon of water. This will cover 1000 sq. ft. In 2 gallons of water, you will use 0.6 fl. oz of Gordons Ornamec Over the Top Grass Herbicide and 0.3 fl. oz of non-ionic surfactant. When using herbicides, it is important that you use the right amount of product per 1000 sq. ft. Water is just a carrier.

QCan Gordons Ornamec Over-the-Top Grass Herbicide be used to kill bermuda grass in an established St. Augustine lawn?

A

No, Gordons Ornamec Over-The-Top Grass Herbicide is not safe to use in St. Augustine grass. Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the St Augustine as well.  In your situation it is recommended to spot treat the Bermuda with a non-selective glyphosate product and kill it directly, and then replant St. Augustine in those areas.

QWill Over the Top Ornamec kill daylilies, knock out roses, sago palms, tulips, easter lilies, begonia, etc?
lily of the nile and color guard agava

A

Gordons Ornamec Over-The-Top Grass Herbicide lists daylilies and Lily of the Nile as tolerable but none of the other ones.  We would recommend checking directly with the manufacturer to confirm it will not harm the other desirables.  PBI Gordon can be reached at 816-421-4070. You can also avoid spraying over the top of these flowers, or spot treat a few areas to test for tolerance before treating a wider area.

QWill Ornamec kill St Augustine grass?
I have Bermuda grass mixed in with my St. Augustine and I am looking for a pesticide that will kill Bermuda and not St Ausgustine.

A

Yes, Gordons Ornamec Over-The-Top Grass Herbicide will kill St. Augustine turf.  Unfortunately, because Bermuda and St. Augustine grasses are closely related, there is not really a product that will remove the Bermuda without also harming the St Augustine. We recommend that you spot treat the Bermuda as much as possible with a non-selective glyphosate product and then replant with St. Augustine in those areas in a couple of weeks when the Bermuda is gone. .

QCan I use Gordons Ornamec Over The Top Grass Herbicide with Tenacity at the same time?
I have a bermudagrass and nimble will infestation. From what I can tell neither herbicide works on both. Thanks.

A

We would need to know what type of lawn you have in order to make a property recommendation or advisement. According to the Tenacity label, bermudagrass is also sensitive to Tenacity as long as the bermudagrass is not dormant.

QWhich product is better for removing Bermuda out of Tall Fescue Grass in Georgia?

A

Bermuda would be considered a grassy weed, so you need a product that is geared towards grassy weeds and not broadleaf weeds.  We want to be clear that bermuda can be suppressed, but it is VERY difficult to kill completely.  It will take multiple treatments to finally kill it.  But Fusilade II is usually the go to product for this issue. 

This is directly off of the product label:

Apply 0.07-0.14 oz/1000 sq. ft. (3-6 oz./A) along with 0.25% v/v (1/2 pt./25 gals.) of a nonionic surfactant. Application should be made every 28 days when the grass weeds are actively growing. The higher rates may result in temporary discolorization of the desirable turf with recovery in 10-14 days. Do not apply to desirable turf which is under stress. For best results, make applications in spring and fall and avoid treatments during July and August.
Complete control of undesirable grass may take 1-2 growing seasons.

Gordons Ornamec Over the Top Grass Herbicide can be used along with a surfactant in Tall Fescue lawns to control Bermuda. Applications should not be made in the hot summer months. The first application should be made in April/May and second application in September/October. Please refer to page 2 of the product label for details on this application to your lawn.

QHow can I kill johnsongrass in my daylilies?
I have several hundred daylilies set out in a fence row along a driveway. Johnson grass has started to appear in the last two years. I need a herbicide that will kill it without killing the daylilies. Thanks

A

You can use a grass killer such as Gordons Ornamec Over-The-Top Grass Herbicide to kill johnsongrass around established daylilies. Ornamec will control Annual Johnsongrass seedlings (sorghum halepense) when 2 to 8 inches tall, before tillering or heading. It will control perennial rhizome johnsongrass that is 8 to 18 inches tall and before booted stage, per the product label. You may need multiple applications for more mature plants. We also suggest using a pre-emergent herbicide in the future for the best control of Jonhsongrass and many other difficult weeds. Prodiamine 65 WDG is safe to use around most turf and ornamentals.

I have torpedo or bermuda grass that is interdispersed throughout the lawn and increasing.

A

Gordons Ornamec Over-The-Top Grass Herbicide will kill grasses that it's applied to, so it would damage your desirable turf. Solitare would be a better option to treat for Torpedo Grass in a Blugrass and Ryegrass lawn.
