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

    Q
    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?
    A

    Gordons Ornamec Over-The-Top Grass Herbicide is a great choice for treatment of grassy weeds in established ornamental beds. Many of the plants you have listed are on the "full tolerant" species list on the product label.  For those not listed, you may want to test a small number of plants or avoid spraying over the top of thos plants.

  • Asked by Jared from Dunwoody, Ga

    Q
    Which 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.

    Q
    How 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.

    Q
    Can 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.

    Q
    Will 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. .

    A

    Gordons Ornamec Over-The-Top Grass Herbicide is best applied to bermuda in the spring as it is just starting to green up usually and in the fall when it is about to go into dormancy as directed on page 2 of the product label.

    Q
    Will Gordons Ornamec Over-The-Top Grass Herbicide kill strawberry plants or grape vines?
    A

    Gordons Ornamec Over-The-Top Grass Herbicide will more than likely kill grape vines since it is labeled for Grape Ivy and it is also labeled for Ornamental Strawberry. It's definitely not labeled to be safe for edible plants.

    Gordons Ornamec Over-The-Top Grass Herbicide is applied at 2.5 fl oz per gallon when spot treating around ornamentals so it should not harm the daylilies at this rate.
