Main Functions

Halosulfuron-Methyl 75% WDG is mainly positioned for crop programs that need focused nutsedge and sedge weed-management support.

It is not positioned as a general grass herbicide or a universal all-weed solution.

Main functions include:

• Supports yellow nutsedge and purple nutsedge management where locally approved
• Helps manage selected sedge weeds in registered crop programs
• Supports selected annual broadleaf weed directions
• Fits fields where nutsedge pressure is the main weed-management issue
• Provides a focused Group 2 sulfonylurea herbicide option
• Can be reviewed for pre-emergence and post-emergence programs according to local label
• Helps local partners build a differentiated sedge-focused herbicide portfolio

Final target claims and use directions must follow local registration and approved label requirements.

Mode of Action

Halosulfuron-Methyl 75% WDG is a single-active Group 2 ALS / AHAS-inhibiting herbicide.

It should be positioned clearly as a selective growth-stopping herbicide for registered sedge and selected broadleaf weed programs.

Group 2 ALS / AHAS Inhibition

Halosulfuron-Methyl belongs to HRAC Group 2.

It works by inhibiting acetolactate synthase, also known as acetohydroxyacid synthase.

This mode of action blocks the production of key branched-chain amino acids required for normal weed growth.

Systemic Growth-Stopping Activity

After uptake, sensitive weeds gradually stop growing.

Visible symptoms may include growth suppression, chlorosis, discoloration, and growing point injury. The speed of visible response depends on weed species, weed stage, crop condition, weather, application timing, and local field practice.

Halosulfuron-Methyl 75% WDG should not be described as a fast contact burndown herbicide.

Root, Shoot, and Foliar Uptake

Halosulfuron-Methyl may be reviewed for both pre-emergence and post-emergence programs where local registration supports these use patterns.

Pre-emergence or soil-directed use, post-emergence foliar use, spray additives, and timing must all follow the approved local label.

Resistance Boundary

Halosulfuron-Methyl 75% WDG is a single Group 2 herbicide.

It does not provide multiple resistance-management modes. Repeated exclusive use of Group 2 herbicides may increase resistance pressure.

Local partners should review local sedge and broadleaf weed resistance status before positioning this product.

Target Weed Directions

Halosulfuron-Methyl 75% WDG is mainly positioned for sedge-focused weed-management programs where approved by local registration.

Target Direction	Practical Positioning
Yellow nutsedge	Core sedge direction where locally approved
Purple nutsedge	Core sedge direction according to approved local label
Selected sedges	Main identity of this product page
Selected annual broadleaf weeds	Supporting weed-management direction
Nutsedge-dominant fields	Best product-fit scenario for portfolio positioning
Mixed sedge and broadleaf pressure	Suitable where sedges are the main issue and broadleaf weeds also need support
Early actively growing weeds	Important timing direction for post-emergence review
Soil-directed programs	Review direction where pre-emergence registration supports use

This product should not be described as controlling all sedges or all broadleaf weeds.

Its main identity is nutsedge and sedge-focused weed management, with selected broadleaf support where locally approved.

Suitable Crops and Application Areas

Rice

Halosulfuron-Methyl 75% WDG can be reviewed for registered rice programs where sedge and selected broadleaf weed pressure need focused management.

Corn and Grain Sorghum

This product can be reviewed for corn and grain sorghum programs where local registration supports Halosulfuron-Methyl use.

Crop stage, crop safety, application timing, and any varietal restrictions must follow the approved local label.

Sugarcane

Sugarcane can be an important crop direction where nutsedge and sedge pressure are key field issues.

Final suitability depends on local registration, crop stage, weed spectrum, application timing, soil condition, and local label restrictions.

Registered Specialty Crops

Some local markets may register Halosulfuron-Methyl in selected cucurbits, cotton, turf, or other specialty uses.

These crop directions should only be used where the approved local label supports the crop scope.

Local Market Application Review

Before registration planning or import cooperation, local partners should review:

• Crop type
• Crop growth stage
• Nutsedge pressure
