What is Isoxaben?

Isoxaben is a broad-spectrum pre-emergent herbicide for broadleaf weeds, grasses, vines, and ornamental trees and shrubs. It hinders or prevents weed seeds from germinating.

Isoxaben is a white to off-white solid with a musty odor that is formulated into water-dispersible powders, granules, or liquid concentrates. Formulated Isoxaben products contain 0.25 to 75% active ingredients, with a balance of solvents and stabilizers.

How Does Isoxaben Work?

Mode of Action

Isoxaben is a cellulose biosynthesis inhibitor (CBI) that disrupts an enzyme necessary for protein synthesis. This disruption halts the germination and growth of susceptible weeds so they do not grow past the seed stage.

Benefits of Isoxaben

Isoxaben is effective in suppressing the growth of a broad range of weeds and, in most cases, can deliver up to 8 months of control. This means you can prevent problem weeds almost all year long. Isoxaben is also selective, so it will only target the problem weeds you want to keep from growing and cause no harm to desired plants.

Drawbacks of Isoxaben

Since Isoxaben is a pre-emergent herbicide active ingredient, it will not effectively control weeds that have already germinated or are firmly established.

Is Isoxaben Safe?

Isoxaben is safe to use on established turf and around ornamentals when applied correctly according to label directions. When using products containing Isoxaben, please make sure to wear the proper PPE, which should include long-sleeved clothing, gloves, and protective eyewear. Check the label for detailed safety instructions. After applying, keep people and pets off the treated area until the product has dried.

What To Expect

Isoxaben should be applied in late summer to early fall, early spring, or any time before germination of target weeds or immediately after cultivation. Most applications should be followed up by watering the area to incorporate the product into the soil surface better.

When the application is timed right, you should expect problem weeds to be unable to grow for up to eight months.
