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.

ANNUAL AND PERENNIAL GRASS CONTROL DIRECTIONS
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.

Gordons Ornamec 170 Grass Herbicide should be mixed at approx. 10 oz per gallon of water to treat grassy weeds in Vinca. Ornamec will not kill existing clover. For clover in ornamental ground covers like vinca major/minor, you can carefully spot treat using a non-selective herbicide such as Killzall Herbicide.

I am trying to kill very stubborn bermuda in my flower beds, and around trees.
Gordons Ornamec 170 Grass Herbicide will work for bermudagrass and is safe around ornamentals. You will need to use more of the product per gallon of water versus the Ornamec Over the Top so you will get more for your money if you purchase the Over the Top.

For spot treatments of tall fescue using Gordons Ornamec 170 Grass Herbicide with hand-operated sprayers, make applications in the spring and fall. You will start applications after green up and take care with applications to tall fescue during the summer months (July and August). You should avoid applications when the turf is under stress due to drought, temperature extremes, or chemical injury. The rate is 2 fl.oz. of product per 1 gallon of water to treat each 1,000 square feet of turf. You will repeat application in 14-21 day intervals if regrowth occurs (may take 1-2 growing seasons for complete control).
