What Is Cyhalofop-butyl 12% + Metamifop 8% EC?

Cyhalofop-butyl 12% + Metamifop 8% EC is a dual-active rice herbicide formulation.

It combines two grass-weed herbicide active ingredients in one emulsifiable concentrate formulation. The product is mainly used after weed emergence in rice fields where annual grass weeds are the primary problem.

This formulation should be positioned as a post-emergence rice grass herbicide. It is not suitable for general weed control claims across all weed types.

Its strongest product identity is clear:

Cyhalofop-butyl 12% + Metamifop 8% EC is a selective post-emergence rice herbicide for annual grass weed control in paddy fields.

How Cyhalofop-butyl and Metamifop Work

Cyhalofop-butyl and Metamifop are both ACCase inhibitor herbicides.

They inhibit acetyl-CoA carboxylase in susceptible grass weeds. This affects fatty acid biosynthesis and stops normal grass weed growth after treatment.

Because both active ingredients belong to the same herbicide mode-of-action group, this formulation should be described carefully:

It is a dual-active grass herbicide, not a dual-mode herbicide.

This distinction is important for resistance management. The product may improve grass weed control programs where locally approved, but it should not be promoted as a resistance-breaking solution for ACCase-resistant weed populations.

Mode of Action: HRAC Group 1 ACCase Inhibitor Herbicide

Cyhalofop-butyl and Metamifop belong to HRAC Group 1 / WSSA Group 1, the ACCase inhibitor herbicide group.

Technical Point	Product Meaning
Active Ingredient 1	Cyhalofop-butyl
Active Ingredient 2	Metamifop
Herbicide Group	HRAC Group 1 / WSSA Group 1
Mode of Action	ACCase inhibition
Main Weed Type	Susceptible annual grass weeds
Main Crop Direction	Rice
Product Positioning	Post-emergence grass weed control

This mode of action makes the product different from ALS inhibitor rice herbicides, quinclorac-based rice herbicides, pre-emergence herbicides and broadleaf weed herbicide programs.

The product should be used according to local label directions and resistance management guidance.

Main Use Direction: Post-Emergence Grass Weed Control in Rice

The main use direction is post-emergence annual grass weed control in rice.

This product is suitable for rice fields where grass weeds have already emerged and are still at a suitable growth stage for treatment. Timely application is important because control may become less reliable when grass weeds are too large, stressed or resistant.

Use Direction	Product Positioning
Post-emergence grass control	Core product direction
Paddy rice weed management	Main crop system
Barnyardgrass direction	Important grass weed target where approved
Chinese sprangletop direction	Relevant where locally registered
Crabgrass and goosegrass direction	Registration-dependent direction
Early grass weed stage	Best use timing
Late large grass rescue	Not the main positioning

This product should not be written as a complete rice weed solution. If broadleaf weeds or sedges are also important in the field, local partners should consider registered herbicide programs with suitable spectrum coverage.

Suitable Rice Field Directions

Cyhalofop-butyl 12% + Metamifop 8% EC can serve different rice field programs, but final use must follow local registration and approved labels.

Transplanted Rice Programs

For transplanted rice programs, this product may be positioned for post-emergence grass weed control where local registration supports use.

Field condition, rice growth stage, weed growth stage, water level and crop health should be checked before application. Correct timing helps improve grass weed control consistency.

Direct-Seeded Rice Programs

For direct-seeded rice programs, this formulation may be used where local labels support use.

Direct-seeded rice can be more sensitive to herbicide timing, water condition and seedling stress. Local partners should confirm crop stage, field condition and label restrictions before promotion or use.

Paddy Rice Distribution Channels

This product is suitable for local rice herbicide portfolios where annual grass weeds are a key field problem.

It can fit markets that need a focused post-emergence grass weed herbicide in EC liquid formulation, especially where paddy rice herbicide channels already accept emulsifiable concentrate products.

Target Weed Directions

Cyhalofop-butyl 12% + Metamifop 8% EC should be written by weed direction, not as a product that controls every weed in rice fields.

Weed Direction	Product Positioning
Barnyardgrass	Core grass weed direction where approved
Chinese sprangletop	Important rice grass weed direction where approved
Crabgrass	Registration-dependent direction
Goosegrass	Registration-dependent direction
Other annual grass weeds	Follow local label
Broadleaf weeds	Not the main target
Sedges	Not the main target
Resistant grass populations	Requires resistance history review

The strongest weed message is annual grass weed control in post-emergence rice programs.

Final weed claims must follow local registration and approved labels.

EC Formulation Features

EC means emulsifiable concentrate.

For buyers, the value of Cyhalofop-butyl 12% + Metamifop 8% EC is practical liquid handling, familiar rice herbicide channel acceptance and bottle or drum packaging flexibility.

EC formulations are suitable for markets that prefer liquid herbicide products. They can fit local distribution channels that require finished liquid formulations for rice weed control programs.

Quality attention for this EC product should focus on active ingredient content, liquid appearance, emulsion stability, solvent system stability, bottle or drum sealing, leakage control, carton protection and storage stability.

EC should not be described as automatically safer, stronger or better than other formulations. The right formulation depends on local registration, market preference, packaging plan and distributor channel.

Why Choose Cyhalofop-butyl 12% + Metamifop 8% EC?

This formulation is suitable for markets that need a focused rice grass weed herbicide.

Its commercial value is mainly:

Two grass-weed herbicide active ingredients in one EC formulation.
Post-emergence positioning for rice fields.
Strong focus on annual grass weed pressure.
Practical liquid formulation for rice herbicide channels.
Suitable bottle, drum and carton packaging options.
Clear product identity for rice herbicide portfolios.
Useful fit for markets where barnyardgrass-type weeds are a key concern.

This product should not be promoted as a broad-spectrum rice herbicide for all weed types. It is best positioned for annual grass weed management where local registration supports use.

Application Guidance

Use Cyhalofop-butyl 12% + Metamifop 8% EC only where locally approved.

This product should be used only on registered rice systems and listed weeds. It is generally positioned for post-emergence application when target grass weeds have emerged and are still at a suitable treatment stage.

Control may become less reliable when weeds are too large, stressed by weather, covered by water, or resistant to ACCase inhibitor herbicides.

Final dose, dilution, application timing, rice growth stage, weed growth stage, spray interval, tank-mix direction, water management and use restrictions must follow the approved local label.

Good timing, correct water management and suitable spray coverage are important for rice field performance.

No specific rate, timing, crop stage or tank-mix instruction should be used without an approved local label.

Water and Field Management

Rice herbicide performance depends strongly on field condition.

Before application, local users should check weed stage, rice stage, water level, field leveling, soil condition, rice seedling health and weather conditions.

Where the local label requires drainage before spraying, water should be managed according to label guidance. Where water return is allowed after application, timing should also follow the approved label.

Poor field leveling, unsuitable water depth, stressed rice seedlings, overgrown weeds, heavy rainfall after application or poor spray coverage may reduce control consistency or increase crop safety risk.

For paddy rice programs, water management should be treated as part of herbicide performance, not as a separate field detail.

Resistance Management

Resistance management is a key part of this product page.

Both Cyhalofop-butyl and Metamifop belong to HRAC Group 1 / WSSA Group 1, the ACCase inhibitor herbicide group. This means the product should not be promoted as a dual-mode resistance management solution.

Recommended market positioning:

Use according to approved local label restrictions.
Do not rely on repeated ACCase-only herbicide programs.
Check local barnyardgrass and grass weed resistance history.
Rotate with herbicides from different mode-of-action groups where locally approved.
Use suitable herbicide programs for broadleaf weeds and sedges where needed.
Apply at the correct grass weed stage.
Integrate field management, water management and timely treatment.
Monitor field performance after application.

Because both active ingredients are Group 1 herbicides, this product should not be described as a resistance-breaking combination. It should be used within a planned rice weed resistance management program.

Crop Safety and Use Boundary

Crop safety and weed control performance depend on rice type, rice variety, growth stage, seedling health, weed stage, field water condition, temperature, rainfall, formulation quality, tank-mix partner and approved local label use.

This product should not be used on non-registered crops or rice systems not supported by local labels. It should not be promoted for broadleaf weed control, sedge control, pre-emergence weed control or non-selective weed control.

Direct-seeded rice and transplanted rice may require different use windows and crop safety checks. Local partners should confirm label restrictions before promotion.

Responsible product communication should avoid absolute claims such as complete weed control, all-rice safety, no resistance concern, all-weed control or guaranteed yield protection.

Registration and Compliance

Before market promotion or field use, local partners should confirm local registration and label requirements.

Final rice system, weed claims, application method, crop stage, weed stage, water management, spray interval, tank-mix direction, safety precautions, label language and import documents must follow local registration and approved label requirements.

For rice herbicide products, crop safety and weed spectrum claims are especially important. The product should only be promoted for approved rice programs and listed weed species.
