What is Halosulfuron?

Halosulfuron is an organic chemical compound belonging to the Alkyl Aryl Ethers family. Halosulfuron is commonly used as a herbicide on agricultural farms to provide control around maize, sugarcane, and rice.

Halosulfuron provides post-emergent control of broad-leaf weeds and sedges in landscapes. Products containing Halosulfuron (such as SedgeHammer) can be used as a spot treatment for purple nutsedge near ornamental trees and shrubs.

How Does Halosulfuron Work?

Halosulfuron mode of action involves interfering with the acetolactate synthase enzyme in targeted plants, which quickly slows cell division and growth at all phases of development.

Benefits of Halosulfuron

Halosulfuron has been shown to be very effective in controlling nutsedge and other types of sedges on turf. It works selectively on many common types of turf, targeting the sedges without injuring the desired grass. It also works systemically, being absorbed into the plant in 24 to 48 hours and then beginning to move through the plant to the roots and nutlets underground, resulting in a quick death after a few weeks.

Drawbacks of Halosulfuron

Halosulfuron is only labeled for nutsedges and horsetail and cannot control other grassy or broadleaf weeds.

Is Halosulfuron Safe?

Halosulfuron is safe to use when applied according to label directions. Always read the product label for safety instructions when handling Halosulfuron.

It is recommended that people use proper personal protective equipment (PPE) before handling or applying Halosulfuron (or any of the other chemicals we carry). Gloves, goggles, and long-sleeved clothing should be the minimum standard. Refer to the label for proper safety instructions.

What To Expect

Plants like nutsedge will be injured about two weeks after applying Halosulfuron, marked by yellowing of the leaves. The sedge plant will then die within three to four weeks.

For best results, products containing Halosulfuron benefit from the use of a non-ionic surfactant. A non-ionic surfactant is a soap-like liquid that helps herbicide stick better when applied to cover the leaf tissue and increases herbicide absorption to kill the weed. A popular Halosulfuron-based product known as Sedgehammer already contains a surfactant in the formula.
