Imox®

What is Imox used for?

Imox is a broad spectrum herbicide for treating emergent vegetation.

What is the active ingredient in Imox herbicide?

The active ingredient is ammonium salt of imazamox.

How to apply Imox herbicide?

Mix Imox with a surfactant and water in a sprayer then spray the plants directly from the tops all the way to where they touch the water.

Does Imox need a surfactant?

Yes, surfactant breaks down the waxy cuticle on the plants and helps the Imox stick.

How does Imox compare to Glyphosate?

Imox and glyphosate are both broad spectrum herbicides safe for aquatic use. They contain different active ingredients.

Is Imox safe for fish and wildlife?

Imox is EPA approved for aquatic use. It is safe to use with the fish, frogs, turtles, etc. in the water as well as the animals that come visit.

Will Imox kill the roots?

Yes! Imox is systemic: it is absorbed through the leaves and stems where it is sprayed then moves through the plant down to the root system to kill both the plant and the roots.

When should I apply Imox and surfactant?

The ideal time to apply Imox herbicide paired with a surfactant is late summer to early fall. This way, the plants are mature so there is plenty of space to get the product onto. The plants are getting ready to pull their energies down to the root system which helps pull the herbicide into the roots as well.

When will I see results after applying Imox?

You may start to see some damage in as little as 2 weeks, but you’ll see full results in 4-5 weeks. Cattails may be cut or pulled when they are brown and crispy. Do not pull water lilies.

Weed identification

Our recommendations:

Emergent weed control

How to apply

• Use with a surfactant, mix products with tap water and evenly spray the entirety of the exposed plants
  • Dilute 2 oz. Imox and 2 oz. surfactant in 1 gallon of water

When to apply

• Apply in late summer to early fall to get better kill of the root systems. At this time, plants are pulling energy into their roots to store for the winter.
• Treat when plants are established and actively growing
• May re-treat 14 days after first application

Other tips

• Treatment is most effective when the plants are mature or close to full grown. This allows for more plant surface to spray enough mixture on.
• Extremely cold or cloudy weather following treatment may result in a delay of the visible effects
