What Is This Triple-Active Rice Herbicide?

This product combines three herbicidal active ingredients in one oil dispersion formulation.

It is designed for rice fields where grass weeds occur together with sedges and broadleaf weeds.

The formulation may be positioned in approved programs for:

• Direct-seeded rice
• Transplanted rice
• Early post-emergence weed control
• Mixed weed populations
• Fields with barnyardgrass-led infestations
• Distributor product lines requiring broader weed-spectrum coverage

It is not a pre-emergence residual herbicide for every rice system.

Use timing, crop selectivity and water management must match the exact local registration.

Importers comparing additional products can review the POMAIS rice herbicide portfolio.

Why Combine Three Active Ingredients?

Rice fields often contain more than one weed group.

A grass-only herbicide may leave sedges and broadleaf weeds untreated. A sedge and broadleaf herbicide may not provide sufficient control of difficult annual grasses.

This formulation combines three functions:

Weed-Control Requirement	Main Active Ingredient Contribution
Annual grass control	Cyhalofop-Butyl
Barnyardgrass reinforcement	Cyhalofop-Butyl + Quinclorac
Selected broadleaf weed control	Quinclorac + Bensulfuron-Methyl
Sedge control	Bensulfuron-Methyl
Mixed weed populations	Combined three-active profile

The fixed-ratio product can reduce the need to measure three separate herbicides in the field.

However, the three active ingredients do not act equally on every weed species.

How Do the Three Active Ingredients Work?

Cyhalofop-Butyl Group 1 Activity

Cyhalofop-Butyl is a selective post-emergence rice herbicide in HRAC Group 1.

It inhibits acetyl-CoA carboxylase, commonly known as ACCase, in susceptible grass weeds. This interrupts fatty-acid synthesis and stops the production of new plant tissue.

Cyhalofop-Butyl is mainly absorbed through weed foliage and moves toward active growing points.

After effective treatment, susceptible grass weeds may show:

• Growth cessation
• Yellowing of young leaves
• Weakening of growing points
• Discoloration
• Gradual plant death

Its main role in this formulation is the control of registered annual grass weeds.

Quinclorac Group 4/29 Activity

Quinclorac is a quinoline-carboxylate rice herbicide with activity that differs between susceptible grass and broadleaf weeds.

It is associated with auxin-type effects and inhibition of cellulose development in susceptible monocot weeds.

Quinclorac may be absorbed through:

• Leaves
• Shoots
• Roots
• Soil-contacting plant tissues

Its main contribution is to reinforce barnyardgrass control and add activity against selected broadleaf weeds.

Quinclorac should not be described as a universal broadleaf or sedge herbicide.

Bensulfuron-Methyl Group 2 Activity

Bensulfuron-Methyl belongs to HRAC Group 2.

It inhibits acetolactate synthase, also known as ALS. This prevents the production of essential branched-chain amino acids in susceptible weeds.

The active ingredient can be absorbed through both foliage and roots and moves toward growing tissues.

Its main role is to extend the product spectrum toward:

• Annual sedges
• Selected perennial sedges where registered
• Aquatic broadleaf weeds
• Semi-aquatic broadleaf weeds
• Other label-approved paddy weeds

Combined Weed-Control Profile

The three active ingredients provide three complementary activity profiles:

Cyhalofop-Butyl targets annual grasses, Quinclorac reinforces barnyardgrass control, and Bensulfuron-Methyl adds sedge and broadleaf weed activity.

This creates a broader weed-management profile than a single-active grass herbicide.

It does not mean that every target weed is affected by all three modes of action.

Target Weed Directions

The following table describes typical product-positioning directions rather than a universal registration label.

Weed Group	Typical Weed Direction	Main Active Contribution
Annual Grasses	Barnyardgrass, jungle rice and other approved annual grasses	Cyhalofop-Butyl + Quinclorac
Sprangletop-Type Grasses	Registered Leptochloa species	Mainly Cyhalofop-Butyl
Sedges	Rice flatsedge, umbrella sedges and other approved species	Bensulfuron-Methyl
Broadleaf Weeds	Monochoria, Ammannia and other registered paddy broadleaves	Bensulfuron-Methyl + Quinclorac
Mixed Weed Populations	Grass, sedge and broadleaf combinations	Three-active formulation
Resistant Populations	Weeds with reduced sensitivity to one or more groups	Performance may be reduced

Exact weed claims must match the approved local label and supporting efficacy data.

Barnyardgrass Management

Barnyardgrass is one of the main commercial targets for this formulation.

Cyhalofop-Butyl and Quinclorac provide two different activity profiles against susceptible barnyardgrass populations.

Best performance is generally expected when weeds are:

• Small
• Actively growing
• Not covered by dense rice foliage
• Not under drought or low-temperature stress
• Within the label-approved leaf stage

Large, tillered or resistant barnyardgrass may respond less consistently.

The product should not be promoted as automatically controlling all Quinclorac- or ACCase-resistant populations.

Sedge and Broadleaf Weed Management

Bensulfuron-Methyl expands the formulation beyond grass-only control.

Potential sedge and broadleaf directions may include:

• Rice flatsedge
• Smallflower umbrella sedge
• Monochoria
• Ammannia
• Arrowhead species
• Other registered paddy weeds

Young and actively growing weeds are generally more responsive than mature plants.

ALS-resistant sedges or broadleaf weeds may show reduced control.

Suitable Rice Production Systems

Direct-Seeded Rice

Direct-seeded rice often faces early competition from grasses, sedges and broadleaf weeds.

Application planning should consider:

• Rice leaf stage
• Weed leaf stage
• Root establishment
• Exposed seed
• Field moisture
• Water depth
• Previous herbicide use

Do not apply before the rice reaches the minimum safe growth stage stated on the label.

Exposed or poorly covered seed may increase crop-injury risk in some direct-seeded systems.

Transplanted Rice

In transplanted rice, the crop should normally be established and actively growing before treatment.

Avoid applying to rice that is:

• Newly transplanted and not rooted
• Severely water-stressed
• Damaged by cold
• Affected by nutrient deficiency
• Under disease or insect pressure
• Recovering from another herbicide treatment

The approved transplanting interval and rice stage must be confirmed for each destination market.

When Should the Product Be Applied?

Early Post-Emergence Timing

This formulation is best positioned as an early post-emergence rice herbicide.

Apply when target weeds are small and actively growing.

Do not wait until:

• Grass weeds have produced multiple tillers
• Sedges have developed large underground structures
• Broadleaf weeds cover the water surface
• The rice canopy prevents spray penetration
• Severe weed competition has already reduced crop growth

Match the Dominant Weed Stage

Grass, sedge and broadleaf weeds may not emerge at the same time.

Before application, identify:

• Dominant weed species
• Weed density
• Weed leaf stage
• Resistant survivors
• Previous treatment history

A fixed-ratio product works best when the main target weeds are within a common, label-approved treatment window.

Avoid Stressed Weeds

Herbicide activity may be reduced when weeds are affected by:

• Drought
• Low temperatures
• Excessive flooding
• Nutrient stress
• Dust or mud covering the foliage
• Poor growth conditions

Allow actively growing foliage to remain exposed where the label requires foliar uptake.

Water Management Before and After Application

Water management is a critical part of paddy herbicide performance and crop safety.

Before Application

Depending on the approved label, field preparation may require:

• Lowering the water level
• Draining standing water
• Exposing weed foliage
• Keeping the soil surface moist
• Avoiding excessive soil cracking
• Preventing water movement between fields

The objective is to improve foliar contact while maintaining suitable rice and soil conditions.

After Application

After the required absorption period, the label may require shallow water to be restored.

Important principles include:

• Follow the registered re-flooding interval
• Avoid early drainage
• Maintain stable water depth where required
• Prevent treated water from leaving the field
• Avoid movement into sensitive crops
• Do not discharge into aquaculture areas

There is no universal drainage period, water depth or re-flooding time for every country.

Application Guidance

1. Confirm the Rice System

Check whether the product is approved for:

• Direct-seeded rice
• Transplanted rice
• Dry-seeded rice
• Water-seeded rice
• Irrigated paddy systems

Do not transfer instructions between production systems without registration support.

2. Identify the Weed Spectrum

Confirm that the field contains weeds controlled by the three active ingredients.

The presence of a mixed weed population does not guarantee that every species appears on the product label.

3. Check Crop and Weed Growth Stages

Apply only when both rice and weeds are within the approved treatment window.

Young rice or mature weeds can reduce selectivity and efficacy.

4. Adjust the Water Level

Lower or drain field water where required so the target foliage is sufficiently exposed.

Do not allow treated water to move into adjacent fields.

5. Shake the OD Container

OD formulations can settle during storage.

Shake, roll or circulate the container according to the product instructions before measuring.

6. Prepare the Spray Tank

Where permitted by the label:

1. Fill the tank partly with clean water.
2. Start agitation.
3. Add the measured product slowly.
4. Add only approved tank-mix partners.
5. Complete filling with water.
6. Maintain agitation throughout application.

7. Apply Uniformly

Use calibrated equipment to avoid:

• Missed strips
• Spray overlap
• Excessive rate
• Uneven droplet distribution
• Drift into sensitive crops
• Product accumulation at field edges

8. Restore Water According to the Label

Allow sufficient time for foliar uptake before restoring field water.

Follow the exact registered interval and water-depth instructions.

OD Formulation Features

OD means Oil Dispersion.

The active ingredient particles are dispersed in an oil-based continuous phase. When added to water, the formulation forms a sprayable dispersion.

Main OD Advantages

A properly developed OD formulation may provide:

• Strong wetting of grassy weed foliage
• Improved spreading on waxy leaf surfaces
• A built-in oil-based delivery system
• Support for high active ingredient loading
• Reduced need to combine multiple field products
• Convenient liquid measurement
• Fixed three-active ratio

The final performance depends on the complete formulation, not only the OD abbreviation.

High-Load Formulation Requirements

This product contains 500 g/L of total active ingredients.

A high-load three-active OD requires careful control of:

• Active ingredient stability
• Particle size
• Viscosity
• Water content
• Dispersion behavior
• Storage temperature
• Packaging compatibility

Bensulfuron-Methyl stability should receive particular attention because sulfonylurea active ingredients can be sensitive to unsuitable formulation conditions.

Continuous Agitation

Maintain agitation:

• During tank filling
• During transport
• Throughout application
• After operational interruptions

Re-agitate fully before spraying resumes.

Rice Selectivity and Crop-Injury Risks

Rice selectivity depends on more than the active ingredient names.

Important factors include:

• Rice variety
• Crop growth stage
• Application rate
• Spray overlap
• Water depth
• Soil texture
• Temperature
• Crop stress
• Previous herbicide treatments

Young or Stressed Rice

Do not apply to rice that has not reached the label-approved stage.

Stressed plants may metabolize the herbicide more slowly and show greater injury.

Quinclorac-Type Symptoms

Under unfavorable conditions, Quinclorac exposure may be associated with:

• Leaf twisting
• Abnormal leaf growth
• Temporary crop suppression
• Delayed development

Risk may increase with excessive rate, overlap or unsuitable crop stage.

ALS-Inhibitor Injury

Excessive Bensulfuron-Methyl exposure may suppress crop growth, especially where rice is stressed or another ALS inhibitor has been used recently.

Spray Overlap

Avoid double application near:

• Headlands
• Field entrances
• Obstacles
• Turning areas
• Irregular field boundaries

The high active ingredient concentration makes accurate calibration especially important.

Resistance Management

This formulation contains three herbicide classifications:

• Cyhalofop-Butyl: HRAC Group 1
• Quinclorac: HRAC Group 4/29
• Bensulfuron-Methyl: HRAC Group 2

The combination can support a broader weed-management program, but it is not resistance-proof.

Weed-Specific Exposure

Not every weed receives effective activity from all three ingredients.

For example:

• Grass weeds may receive activity mainly from Cyhalofop-Butyl and Quinclorac.
• Sedges may depend mainly on Bensulfuron-Methyl.
• Some broadleaf weeds may receive activity from Bensulfuron-Methyl and Quinclorac.
• Resistant populations may survive one or more components.

Avoid Repeated Dependence

Do not rely on the same triple-active product every season without changing the program.

Repeated use can select weeds with multiple resistance traits.

Recommended Resistance Principles

• Identify weed species before spraying.
• Apply to small, actively growing weeds.
• Use the complete registered rate.
• Avoid repeated consecutive applications.
• Rotate with effective herbicides outside Groups 1, 2 and 4/29.
• Use pre-emergence and post-emergence programs where approved.
• Remove surviving weeds before seed production.
• Clean equipment between fields.
• Maintain treatment records.
• Integrate water, cultivation and crop-rotation practices.

Unexpected survivors should be investigated rather than treated immediately with the same product.

Comparison with Related Rice Herbicides

For sedge and broadleaf-focused programs, see the Bensulfuron-Methyl herbicide.

Tank Mixing and Adjuvant Use

Do not assume that additional oil or surfactant is required.

The OD formulation already contains an oil-based delivery system.

Extra adjuvant may increase:

• Rice injury
• Leaf penetration
• Spray overlap effects
• Tank-mix instability
• Non-target exposure

Use only label-approved adjuvants.

Compatibility Testing

For unfamiliar mixtures:

• Use the intended water source
• Follow the planned mixing order
• Use proportional quantities
• Check for separation or sediment
• Observe excessive foam or heat
• Review crop-safety information

Physical compatibility does not guarantee weed control or rice safety.

Herbicide Mixtures

Some broadleaf and sedge herbicides may reduce the grass activity of ACCase-inhibiting herbicides under certain conditions.

Do not make additional tank mixtures unless the exact combination is supported by the local label and efficacy data.

Rotational, Water and Field Restrictions

Quinclorac and Bensulfuron-Methyl may create rotational-crop restrictions depending on:

• Application rate
• Soil pH
• Soil texture
• Rainfall
• Temperature
• Time before planting

Sensitive rotational crops should not be planted until the registered interval has passed.

Treated Water

Do not use treated paddy water to irrigate sensitive crops unless the label specifically permits it.

Prevent discharge into:

• Vegetable fields
• Orchards
• Nurseries
• Aquaculture ponds
• Natural wetlands
• Surface-water systems

Rice Straw and Crop Residues

Use restrictions for treated rice straw, forage or crop residues depend on the destination-market label.

Equipment Cleaning

Clean the spray tank, hoses, filters and nozzles after application.

Small residues of high-load herbicide can injure sensitive crops treated later with the same equipment.
