DIRECTIONS FOR USE

APPLICATION DIRECTIONS: ORNAMEC 170 GRASS HERBICIDE can be used to control grass weeds in many newly transplanted and established ornamentals, trees, shrubs and groundcovers. Apply to actively growing grass weeds before they exceed the recommended growth stages shown below.

Do not apply ORNAMEC 170 GRASS HERBICIDE if rainfall is expected within 1 hour.

“Over-the-top” applications are recommended for the ornamentals listed in Table 1 (see label). “Over-the-top” applications are defined as spray patterns delivered to the upper portions of the established ornamentals and target weeds. Use sufficient spray volumes to ensure a uniform distribution and complete spray coverage of the target weeds.

Directed spray applications are recommended for the ornamentals listed in Tables 2, 3, and 4 (see label). Directed spray applications are defined as spray patterns aimed or directed toward the lower portion of the established ornamentals, and this method of application will minimize the phytotoxicity of the desired species. If the growth habit of the plant or other factors do not allow a directed spray, an over-the-top application can be made to plants in Tables 2, 3, and 4. However, there is the possibility of damage in the range listed for each table when applied at label rates. Refer to Tables 2, 3, and 4 (see label) for the list of ornamental species appropriate for directed spray applications.

DO NOT APPLY TO ORNAMENTALS THAT MAY BE HARVESTED FOR FOOD WITHIN ONE YEAR AFTER APPLICATION.

SPOT TREATMENTS FOR ORNAMENTALS, TREES, SHRUBS AND GROUNDCOVERS: Mix ORNAMEC 170 GRASS HERBICIDE with water according to the amounts shown in the following chart. Spray to obtain thorough coverage, but do not spray to runoff. Retreat if necessary.

BROADCAST APPLICATION FOR ORNAMENTALS, TREES,SHRUBS AND GROUNDCOVERS:

ANNUAL AND PERENNIAL GRASS CONTROL DIRECTIONS

  • For annual grass species, use 6 to 9 fluid ounces of ORNAMEC 170 GRASS HERBICIDE per 1000 square feet.
  • For perennial grass species, use 9 fluid ounces of ORNAMEC 170 GRASS HERBICIDE per 1000 square feet per application. Three applications will be needed.
  • The maximum amount of fluazifop-R-butyl per treated area per season is 1.1 pounds active ingredient per acre per season (27 fl. oz. per 1000 sq. ft. per season).
  • Spray to obtain thorough coverage of grass foliage, but not to runoff. Repeat treatments may be necessary to provide full season control.
  • Use standard hollow cone or flat fan nozzles.
  • Apply ORNAMEC 170 GRASS HERBICIDE herbicide to actively growing grasses before they exceed the recommended growth stages shown below.
  • Do not apply ORNAMEC 170 GRASS HERBICIDE 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 170 GRASS HERBICIDE herbicide when the first grass species in a mixed grass weed population reaches the recommended growth stage for treatment.

    it works

    By Gary on 04/29/2019

    This stuff works to eradicate bermuda from fescue , but don't try to use extra strong dosage. It usually will take 2 or 3 applications over a period of a couple of years, depending on how bad the bermuda infestation is. Apply in spring and fall when fescue is strongest. It will weaken the fescue , but it will come back in a few weeks. Don't apply in summer and follow directions closely. This is the only product i have found that will kill bermuda without killing the fescue too. One more thing, it takes about a week before you start seeing a yellowing or dying of the grass so be patient, it works...

    Bermudagrass in Zoysia turf

    By Michael on 06/19/2020

    I bought this herbicide because the label says it can be used to kill or suppress Bermudagrass in a Zoysia lawn. I have this problem in my lawn in Central Florida. I spot applied Ornamec 170 about 3-4 weeks ago, and put on another application after two weeks. The label states that the treatment may take one to two growing seasons to completely eradicate the problem. At this point I can state that Ornamec is certainly suppressing the Bermudagrass, and it effects the Zoysia as well but not as severely. I believe the turf will survive and the Bermudagrass will die, but do not know how long this will take. I will revise this review or add another one in the Fall when I know more.

We cannot say for certain if the bahia grass would be harmed or not by Gordons Ornamec 170 Grass Herbicide as this product is not specifically labeled for bahia. If you do not wish to harm the bahia, we would not recommend using this product as bahia is not labeled as tolerable. Also, if you are wanting to control the bahia, we cannot guarantee this product would work for your situation.

Q
Can I use Ornamec 170 to spot treat Bermuda grass without causing harm to my bahiagrass?

I have large patches and isolated spots of Bermuda grass in my Bahia lawn.

A

Gordons Ornamec 170 Grass Herbicide can only be used on cool season turf to remove bermuda, it can also injure the bahia.  There is no selective product to remove one from the other really.   Your best option would be to spot treat with a glyphosate based product and then reseed/sod the areas

Q
Is Gordons Ornamec 170 Grass Herbicide safe to use on my Bahia grass lawn to control Bermuda grass in central Florida?
A

Gordons Ornamec 170 Grass Herbicide is not labeled to control bermudagrass in bahiagrass.   In your situation, it is recommended to spot treat the Bermuda with Round Up and kill it directly, and then replant Bahia in those areas. We do carry some professional round up products here
