Ornamec 170 Grass Herbicide, manufactured by PBI Gordon, is a post-emergent selective herbicide meant to control annual and perennial grassy weeds that show up on landscape beds. Ornamec 170 works systemically to control unwanted grasses in areas with ornamental plants, shrubs, trees, flowers and groundcover.
Ornamec 170 can be safely applied "over-the-top" without injuring desired plants. Ornamec works fast and will hinder the growth of grassy weeds in as quick as 48 hours. If you are looking for grassy weed control, Ornamec provides great value.
Tools Needed
To use Ornamec 170 Grass Herbicide, you will need to mix the product into a sprayer of your choosing such as a backpack, hose-end or hand-pump sprayer. For the average job, a hand-pump gallon sprayer works best.
How to Use
- Step 1: Determine how much Ornamec 170 you need for your application by first calculating the square footage of your yard. To do this, you will need to measure and multiply the area length times the width (length x width=square footage). The application rates for Ornamec 170 vary depending on the weed being treated, where you are treating and whether you are conducting a broadcast treatment or spot treatment. For example, Broadcast treatments for Ornamentals, Trees, Shrubs and Groundcovers use 6 to 9 fl. oz. per gallon of water per 1,000 sq. ft. Spot treatments for Bermudagrass on Tall Fescue Turf should be applied at a rate of 2 fl. oz. per gallon of water per 1,000 sq. ft.
- Step 2: Fill your sprayer tank halfway with the appropriate amount of water. Add the correct measured amount of Ornamec 170 based on your calculations and then add the remaining half of water. Agitate well in the sprayer to ensure it's well mixed.
- Step 3: Broadcast spray or spot treat based on the severity of your grassy weed problem, making sure to get even coverage via fan spray setting.
- Step 3: Reapply the product in 14 to 21 days intervals if weeds are still persisting and repeat as needed for full control all season long.
Where to Use
Ornamec 170 can be used to control grass weeds in many newly transplanted and established ornamentals, trees, shrubs and groundcovers.
When to Use
Apply Ornamec 170 to actively growing grass weeds before they exceed the recommended growth stages. Make applications on warm, calm days when wind speeds are low to minimize drift and when rain is not in the immediate forecast.
Do not apply this product if rainfall is expected within 1 hour of application.
Safety Information
Ornamec 170 is safe for pets and children when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Keep children and pets out of treated areas until the spray has completely dried.
Special Considerations
Do not apply Ornamec 170 Grass Herbicide to grasses that are stressed due to moisture, temperature, low soil fertility or mechanical/chemical injury. Always check the label before purchasing to make sure that the product is listed to address your specific weed problem and to check if it is safe to use on your landscape.

Great for getting grass out of ornamentals
This grass herbicide works great for getting the grass out of ornamental flowers, such as the Creeping Phlox and Iris. It is easy on the flowers, but gets rid of the grass easily.
