Ornamec 170 Grass Herbicide

The active ingredient in Ornamec is fluazifop-P-butyl, a member of the aryloxyphenoxypropionate family of chemicals. Ornamec inhibits the division and expansion of plant cells through an enzyme that encourages growth. For Bermuda grass, this ingredient is poisonous since it inhibits the production of essential lipids they need and lack in straw, which causes weak or dead Bermuda grass.

This is one of the sweet things about Ornamec: it hurts tall fescue less and so is a good thing to have around for spot-treating lawn weeds where Bermuda grass isn’t wanted.

Application and Usage

To effectively use Ornamec herbicide to control Bermuda grass in tall fescue turfgrass, apply:

• Timing: Apply Ornamec herbicide to actively growing Bermuda grass and tall fescue beginning in late spring through early summer. Do not treat during times of stress, i.e., drought or high temperatures.
• Mow: Mowing at the right height for your tall fescue grass before you treat it with herbicides. This is another method to obtain more coverage of the herbicide and to ensure that you get it directly on Bermuda grass.
• Mixing and Application: Prepare a spray mix of Ornamec herbicide as directed on the label and apply to the turf area using a calibrated sprayer for complete coverage. Make sure to avoid spray pattern overlap, which can lead to over-application and cause damage to tall fescue.
• Post-Treatment Care: Wait a few days after applying the herbicide. You can see symptoms of Bermuda grass decline, including browning and yellowing. Bermuda grass will eventually stress and die out, while the tall fescue should not be bothered as much.
• Repeat Treatments: In some cases, Ornamec herbicide repeat applications will be necessary for bermudagrass control. Applications should be applied for the number of days between each application specified on the label.
• Lawn Care Maintenance: Once Bermuda grass has been managed successfully, maintain the thirty fescue lawn as you would any other (mowing height, water management, and fertility) to encourage healthy growth and recovery.

It's important to indicate that Ornamec is technically designed for tall fescue lawns, and could not perhaps be the best choice to mix with other kinds of grass. Always be sure to read and follow label directions and take appropriate precautions before applying.

Key Features

Active Ingredient

The active ingredient in Ornamec 170 is fluazifop-P-butyl, which belongs to the aryloxyphenoxypropionate chemical family. On Bermuda grass, it prevents the production of vital lipids needed by the grass to survive, and therefore, over time it will weaken and die. Importantly, Ornamec is designed to protect tall fescue grasses, so it can be a fantastic tool for specific weed control.
