What Is Cyhalofop + Metamifop + Penoxsulam OD?

This product is a high-load post-emergence rice herbicide containing three active ingredients.

Its main role is the control of mixed weed populations where annual grasses are the primary problem and selected sedges or broadleaf weeds are also present.

The product is not a pre-emergence residual foundation. It should be applied after target weeds have emerged and while they are still within the susceptible growth stages stated on the label.

It is also not a non-selective herbicide. Use must be limited to approved rice systems, varieties and crop stages.

Importers building a broader rice portfolio can position this product alongside other selective herbicide products.

Why Combine Three Active Ingredients?

Concentrated Group 1 Grass-Weed Foundation

Cyhalofop-Butyl and Metamifop both target susceptible grass weeds through ACCase inhibition.

Together, they create a strong grass-led commercial positioning for rice fields with barnyardgrass, junglerice, sprangletop-type grasses and other labeled annual grass weeds.

The two active ingredients are chemically different, but they belong to the same HRAC group. Their combination does not create two separate modes of action.

Group 2 Spectrum Expansion

Penoxsulam broadens the product profile beyond a grass-only herbicide.

Depending on registration, it may add activity against:

• Annual sedges
• Selected broadleaf weeds
• Additional susceptible grass weeds
• Mixed weed populations

This makes the formulation suitable for fields where one grass-focused product may not provide sufficient spectrum.

Three Active Ingredients but Two Modes of Action

The correct technical description is:

• Three herbicidal active ingredients
• Two HRAC groups
• Group 1 + Group 2
• Grass-led mixed weed control

The product should not be described as a three-mode-of-action herbicide.

How Does the Herbicide Work?

Cyhalofop-Butyl Mode of Action

Cyhalofop-Butyl belongs to HRAC Group 1.

It inhibits acetyl-CoA carboxylase, also known as ACCase. This enzyme is required for normal fatty acid production in susceptible grass weeds.

After foliar uptake, Cyhalofop-Butyl moves toward active growing points. Fatty acid and membrane development are disrupted, causing weed growth to stop.

Visible symptoms usually develop gradually rather than immediately.

Metamifop Mode of Action

Metamifop is also an HRAC Group 1 ACCase inhibitor.

It is absorbed mainly through weed foliage and moves within susceptible grass plants. Growth points become inactive before yellowing, tissue decline and plant death develop.

Metamifop strengthens the grass-weed direction of the premix. It should not be presented as a separate resistance-management group from Cyhalofop-Butyl.

Penoxsulam Mode of Action

Penoxsulam belongs to HRAC Group 2.

It inhibits the acetolactate synthase enzyme required for the production of essential branched-chain amino acids.

After uptake, susceptible weeds stop normal cell division and growth. Yellowing and decline develop over time.

Penoxsulam provides the main spectrum extension toward selected sedges and broadleaf weeds.

Combined Field Response

The combined biological sequence is:

Group 1 activity stops fatty acid production in susceptible grasses → Group 2 activity stops amino acid production in susceptible grasses, sedges and broadleaf weeds → weed growth stops and visible decline develops

The product is systemic rather than a rapid contact-burn herbicide.

Users should evaluate weed growth cessation and progressive decline, not only immediate leaf injury.

What Weeds Can the Product Control?

The commercial focus should remain on mixed weed populations in rice.

Weed Direction	Typical Examples	Main Product Contribution
Annual Grass Weeds	Barnyardgrass, junglerice and related Echinochloa species	Mainly Cyhalofop-Butyl and Metamifop, with Penoxsulam support
Sprangletop-Type Grasses	Leptochloa species	Mainly Group 1 components
Other Rice Grass Weeds	Ischaemum and other label-listed species	Product-specific activity
Annual Sedges	Cyperus species and other labeled sedges	Mainly Penoxsulam
Broadleaf Rice Weeds	Monochoria, Eclipta and other susceptible species	Mainly Penoxsulam
Group 1-Resistant Weeds	Resistant grass populations	Control may be reduced or absent
Group 2-Resistant Weeds	Resistant sedges, broadleaves or grasses	Control may be reduced or absent
Large or Heading Weeds	Advanced grass weeds	Reduced reliability

Exact weed claims must be confirmed by the approved local label and efficacy data for this 380 g/L OD formulation.

Annual Grass Weed Control

Annual grasses are the primary target direction.

The product may be positioned against young and actively growing:

• Barnyardgrass
• Junglerice
• Sprangletop species
• Other approved annual grasses

Control is generally more reliable before heavy tillering or seed-head formation.

Large, stressed or resistant grass weeds may survive treatment.

Sedge and Broadleaf Weed Control

Penoxsulam adds activity against selected sedges and broadleaf weeds.

Potential directions may include:

• Smallflower umbrella sedge
• Rice flatsedge
• Monochoria
• Eclipta
• Other locally registered weeds

The product should not be promoted as controlling every rice sedge or broadleaf species.

Resistant Weed Populations

The formulation cannot be assumed to control weeds resistant to Group 1 or Group 2 herbicides.

Two Group 1 active ingredients do not automatically restore control of a Group 1-resistant population.

Some resistance mechanisms may reduce sensitivity to multiple active ingredients in the same premix.

Fields with previous herbicide failure should be investigated before product selection.

Suitable Rice Systems

The product should only be positioned for rice systems included on the destination-market label.

Direct-Seeded Rice

Direct-seeded rice may be an important commercial direction where the formulation is registered.

Potential systems include:

• Dry direct-seeded rice
• Wet direct-seeded rice
• Water-seeded rice

Each system has different crop stages, weed-emergence patterns and water-management requirements.

A registration for one direct-seeded system does not automatically cover all three.

Transplanted Rice

Transplanted rice use should only be included where the exact product label supports it.

The application decision should consider:

• Transplant establishment
• Rice growth stage
• Weed size
• Field water
• Variety tolerance
• Previous herbicide treatments

Weak or newly transplanted rice may be more vulnerable to stress.

Irrigated Paddy Systems

In irrigated paddies, water management affects both weed exposure and environmental risk.

The user must follow the label instructions for:

• Water depth before treatment
• Field drainage
• Reflooding time
• Water-retention period
• Water discharge
• Movement between treated and untreated fields

For broader crop-program planning, review our rice weed management solutions.

When Should the Herbicide Be Applied?

Post-Emergence Application

This product is primarily a post-emergence herbicide.

The rice crop and target weeds must both be within the approved growth stages.

Do not use it as a substitute for a pre-emergence residual program unless the label specifically includes that use.

Apply to Young Weeds

Young weeds are generally easier to control because they have:

• Fewer tillers
• Smaller root systems
• Active growing points
• Greater foliar activity
• Less stored energy

Waiting until grasses are large or heading can reduce control.

Treat During Active Growth

Performance is generally more reliable when weeds are actively growing.

Favorable conditions may include:

• Adequate moisture
• Suitable temperatures
• Exposed weed foliage
• No severe drought or flooding stress
• No immediate heavy rainfall
• Rice plants in acceptable condition

Cold, drought or excessive water stress may slow herbicide uptake and visible symptoms.

Avoid Rescue-Treatment Expectations

The product should not be positioned as a guaranteed rescue treatment for:

• Dense mature barnyardgrass
• Grass weeds with multiple tillers
• Heading weeds
• Severe mixed infestations
• Group 1-resistant weeds
• Group 2-resistant weeds

Early identification remains important.

Rice Water Management

Water management must be treated as part of the herbicide program.

Before Application

Depending on the label, the field may need to be drained or the water level reduced.

The objective is to expose enough weed foliage for effective spray contact.

Before treatment:

• Check field water depth
• Expose target weed leaves
• Stop water discharge
• Prevent movement into neighboring fields
• Remove conditions that block spray coverage
• Follow local drainage instructions

Do not assume that every rice herbicide should be applied directly over deep water.

After Application

The label may require a defined period before reflooding.

Reflooding too early may:

• Reduce foliar uptake
• Move the herbicide away from weeds
• Lower field performance
• Increase water contamination risk

Delaying reflooding too long may also stress the rice or change weed response.

Follow the approved timing.

Water-Retention Requirements

Treated water may need to remain in the field for a specified period.

Do not discharge treated paddy water into:

• Rivers
• Canals
• Fish ponds
• Adjacent crops
• Wetlands
• Irrigation systems
• Drinking-water sources

The exact retention period must come from the registered label.

Application Guidance

The following information describes professional application principles and does not replace the approved label.

1. Identify the Weed Species

Before spraying, determine:

• Dominant grass weeds
• Sedge species
• Broadleaf species
• Weed growth stages
• Tiller development
• Previous control failures
• Resistance history

Mixed weed populations should be evaluated by species, not only by total density.

2. Confirm the Rice System

Check:

• Direct-seeded or transplanted rice
• Crop variety
• Crop growth stage
• Root establishment
• Field-water condition
• Salinity or other stress
• Previous herbicide injury

Use only on approved rice systems.

3. Review Resistance History

Check whether the field has experienced reduced control from:

• Cyhalofop-Butyl
• Metamifop
• Penoxsulam
• Other ACCase inhibitors
• Other ALS inhibitors

Changing from one Group 1 active ingredient to another is not a complete mode-of-action rotation.

4. Shake the OD Container

OD formulations contain dispersed active ingredient particles.

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

5. Prepare the Spray Tank

Where permitted by the label:

1. Clean the tank and spray system.
2. Add part of the required clean water.
3. Start agitation.
4. Measure the OD product accurately.
5. Add it slowly to the agitated water.
6. Add an approved adjuvant where required.
7. Add compatible partners only where permitted.
8. Complete filling with water.
9. Maintain agitation throughout application.

6. Cover Exposed Weed Foliage

The spray should reach actively growing weed leaves.

Coverage may be reduced by:

• Deep standing water
• Dense rice canopy
• Mud deposits
• Floating plant material
• Poor nozzle selection
• Excessive droplet size
• Uneven field surfaces

7. Avoid Spray Overlap

Overlap can increase rice exposure and crop-injury risk.

Pay particular attention near:

• Headlands
• Field edges
• Turning areas
• Obstacles
• Irregular boundaries

8. Follow Reflooding Instructions

Do not reflood based only on local habit.

Use the interval stated on the exact product label.

9. Clean the Equipment

After use, clean:

• Tank
• Hoses
• Pumps
• Filters
• Nozzles
• Boom ends
• Induction systems

Residues may injure sensitive crops treated later.

Crop Selectivity and Injury Risks

Rice tolerance depends on the formulation, rate, crop stage and environmental conditions.

Conditions That May Increase Crop Injury

Risk Factor	Why It Matters
Extreme Heat or Cold	Alters crop metabolism and herbicide response
Drought Stress	Weakens rice recovery
Waterlogging or Deep Flooding	Reduces crop vigor and changes uptake
High Salinity	Adds physiological stress
Weak Root Establishment	Increases crop sensitivity
Disease or Insect Damage	Reduces crop recovery capacity
Previous Herbicide Injury	Increases combined stress
Spray Overlap	Delivers an excessive rate
Incorrect Adjuvant	May increase rice uptake
Unapproved Tank Mix	Can reduce selectivity
Application Outside the Crop Window	Increases uncertainty and injury risk

Temporary Crop Effects

Under unfavorable conditions, rice may show temporary:

• Yellowing
• Growth slowing
• Leaf discoloration
• Reduced vigor

The crop should be monitored according to the local label and registration data.

The product should not be described as safe for every rice variety or every field condition.

OD Formulation Features

OD means Oil Dispersion.

In an OD formulation, fine active ingredient particles are dispersed in an oil-based continuous phase.

After dilution in water, the formulation creates a spray dispersion suitable for foliar application.

Practical OD Characteristics

The oil-based system may support:

• Leaf wetting
• Spray retention
• Foliar deposition
• Uptake under approved conditions
• High active ingredient loading
• Factory-controlled active ratios

The OD formulation does not automatically remove the need for correct water volume, agitation or an approved adjuvant.

The product contains a total active ingredient loading of 380 g/L.

Quality Parameter	Buyer Relevance
Cyhalofop-Butyl Content	Confirms the declared 200 g/L concentration
Metamifop Content	Confirms the declared 150 g/L concentration
Penoxsulam Content	Confirms the declared 30 g/L concentration
Content Uniformity	Ensures consistent three-active distribution
Particle Size Distribution	Influences storage and spray performance
Dispersion Stability	Reduces separation after dilution
Redispersibility	Supports recovery after storage
Viscosity	Affects pouring, pumping and filling
Wet Sieve Residue	Reduces nozzle-blockage risk
Persistent Foam	Affects spray-tank operation
Crystallization Control	Helps maintain storage stability
Low-Temperature Stability	Important for cold-market transport
Heat Stability	Important for tropical storage and shipping
Packaging Compatibility	Reduces leakage, swelling and seal failure

Content Uniformity

Penoxsulam is present at a lower concentration than the two Group 1 components.

Uniform distribution is important to maintain:

• Consistent weed spectrum
• Pack-to-pack performance
• Label compliance
• Batch reliability
• Crop-selectivity expectations

Redispersibility

Some settling may occur during storage.

The formulation should return to a uniform state after the approved shaking or circulation procedure.

Hard sediment or persistent phase separation may indicate a formulation or storage problem.

Packaging Compatibility

Bottle, cap, seal and label materials should be reviewed against the oil-based formulation.

Checks should include:

• Leakage
• Bottle swelling
• Seal compatibility
• Cap security
• Label adhesion
• Product evaporation
• High-temperature storage
• Long-distance shipment

Comparison with Related Rice Herbicides

This three-active OD product should be differentiated from simpler rice herbicide combinations.

Product Direction	Main Positioning	Modes of Action	Weed Spectrum
Cyhalofop-Butyl 200 g/L + Penoxsulam 30 g/L OD	Simpler mixed-weed program	Group 1 + Group 2	Grasses, selected sedges and broadleaf weeds
Cyhalofop-Butyl + Metamifop EC	Grass-focused rice herbicide	Group 1 only	Mainly annual grass weeds
Cyhalofop 200 + Metamifop 150 + Penoxsulam 30 OD	High-load Group 1 grass foundation with Group 2 spectrum expansion	Group 1 + Group 2	Grass-led mixed weed spectrum

The new product is not automatically better in every field.

Selection depends on:

• Dominant weed species
• Weed growth stage
• Resistance status
• Rice system
• Local registration
• Water-management program
• Required spectrum

Buyers comparing a simpler two-active option can review Cyhalofop-Butyl 200 g/L + Penoxsulam 30 g/L OD.

Tank Mixing and Adjuvant Requirements

Tank mixing must follow the exact product label.

Adjuvant Selection

Some rice herbicide programs require a specific:

• Crop oil concentrate
• Methylated seed oil
• Nonionic surfactant
• Other registered adjuvant

Do not assume that all adjuvants are interchangeable.

The wrong adjuvant may cause:

• Reduced weed control
• Excessive rice uptake
• Crop injury
• Spray instability
• Excessive foam

Physical Compatibility

Tank-mix behavior may be influenced by:

• Water hardness
• Water pH
• Mixing order
• Partner formulation
• Fertilizer salts
• Adjuvant type
• Tank temperature
• Number of products

Conduct a small compatibility test before preparing an unfamiliar mixture.

Do Not Store the Spray Mixture Overnight

Prepare only the volume required for the treatment area.

Extended standing may cause:

• Separation
• Settling
• Uneven concentration
• Difficult cleaning
• Reduced spray consistency

Maintain agitation throughout application.

Resistance Management

The formulation contains:

• Cyhalofop-Butyl: HRAC Group 1
• Metamifop: HRAC Group 1
• Penoxsulam: HRAC Group 2

The product therefore has two modes of action.

Group 1 Resistance

Resistance to ACCase-inhibiting herbicides can reduce the activity of both Cyhalofop-Butyl and Metamifop.

Two Group 1 active ingredients should not be treated as a complete resistance solution.

Group 2 Resistance

ALS-resistant sedges, broadleaf weeds or grass weeds may survive Penoxsulam.

Where Group 2 resistance is established, spectrum expansion may be reduced.

Resistance-Management Principles

• Identify the target weeds correctly.
• Apply to young susceptible weeds.
• Use the complete registered rate.
• Do not rely on the same Group 1 + 2 program every season.
• Use effective pre-emergence herbicides from other HRAC groups where registered.
• Rotate crops where practical.
• Manage paddy water correctly.
• Remove or treat surviving weeds before seed production.
• Clean equipment between infested fields.
• Use cultural or mechanical weed control.
• Test suspicious populations for resistance.
• Maintain field-treatment records.

Surviving Weeds

Investigate weeds that remain healthy after a correctly applied treatment.

Do not automatically repeat the same premix.

Survivors may result from:

• Resistance
• Incorrect weed identification
• Advanced growth stage
• Poor coverage
• Wrong water management
• Crop stress
• Incorrect rate
• Rainfall or reflooding issues

Rotational Crops and Field Restrictions

Penoxsulam may provide some soil residual activity.

Plant-back restrictions depend on:

• Application rate
• Soil type
• Soil pH
• Temperature
• Moisture
• Rainfall
• Rotational crop
• Destination-market label

Sensitive crops should not be planted before the approved interval.

There is no universal plant-back period for every market.
