Ornamec 170 Grass Herbicide

Ornamec contains the active ingredient fluazifop-P-butyl, which belongs to the aryloxyphenoxypropionate chemical class. Ornamec prevents plant cells from dividing and expanding by acting as an antagonist to an enzyme that promotes growth. This component is toxic for Bermuda grass as it blocks the formation of important lipids that these straws cannot survive without, leading to poorly growing or dead Bermuda grass. 

This is one of the sweet things about Ornamec: it does less damage to tall fescue and so is a great thing to have on hand for spot-treating lawn weeds where Bermuda grass is not welcome.

Application and Usage

For best results using Ornamec herbicide to treat Bermuda grass in tall fescue grass lawns, 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: Mow your lawn to the proper height for your tall fescue grass before you apply herbicides. This is another technique for more coverage of the herbicide and contact with the Bermuda grass.
• Mixing and Application: Mix the Ornamec herbicide according to the label directions and apply with a calibrated sprayer to ensure uniform coverage throughout the lawn. Be sure to prevent the overlapping of spray patterns, as it may result in excessive application and potential injury 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 instances, re-applications of Ornamec herbicide must be made to achieve Bermuda grass control. Applications should be made at the specified intervals recommended on the label.
• Lawn Care Management: Following effective management of Bermuda grass, be sure to follow general lawn maintenance practices for your tall fescue lawn (i.e., correct mowing height, watering management, proper fertility) to promote healthy growth and recovery.

It’s a good point to highlight that Ornamec is really meant for use in tall fescue lawns, and might not be the best to work with other grasses. Be sure to always read the product label instructions and take all necessary precautions before applying.

Key Features

One of the most widely used weed killers for grass, Ornamec grass herbicide, is the preferred choice for warm-season and cool-season lawns.

Active Ingredient

Ornamec 170's active ingredient is fluazifop-P-butyl, a member of the aryloxyphenoxypropionate chemical group. It works on Bermuda grass by denying it the production of essential lipids that the grass requires to thrive, and thus it will weaken and die over time. Crucially, Ornamec is formulated to spare tall fescue grass, so it’s a valuable tool in targeted weed control.
