Main Functions

Penoxsulam 25 g/L OD is mainly positioned for rice herbicide programs that need a single-active Group 2 ALS inhibitor.

It can support registered paddy weed-management programs where selected mixed weed pressure is a key issue.

Main functions include:

• Supports selected weed management in paddy rice
• Helps manage selected annual grass weeds where locally approved
• Supports selected sedges in rice weed-management programs
• Provides a program-fit direction for selected broadleaf weeds
• May fit selected aquatic weed directions according to approved local label
• Supports rice herbicide portfolios that need a Group 2 active ingredient
• Helps local partners review rice herbicide registration and distribution opportunities

Penoxsulam 25 g/L OD should not be promoted as a universal rice herbicide. Final target claims must follow local registration and approved label directions.

Mode of Action

Penoxsulam is a HRAC Group 2 herbicide.

It inhibits acetolactate synthase, also known as acetohydroxyacid synthase. This enzyme is involved in the biosynthesis of key branched-chain amino acids in sensitive weeds.

After uptake, sensitive weeds stop growing gradually. Visible symptoms may develop over time, depending on weed species, weed stage, water management, rice system, weather, and local application conditions.

Because Penoxsulam is a single Group 2 ALS / AHAS inhibitor, repeated use may increase resistance pressure. It should not be promoted as a resistance-proof rice herbicide.

For professional rice weed-management programs, Penoxsulam 25 g/L OD should be reviewed together with local weed spectrum, existing ALS resistance pressure, rotation options, and approved application directions.

Target Weed Directions

Penoxsulam 25 g/L OD is positioned for selected rice-field weed directions where approved by local registration.

Target Direction	Practical Positioning
Selected annual grass weeds	Rice field grass weed direction where locally approved
Barnyardgrass-type weeds	Review direction depending on local label and resistance status
Selected sedges	Important fit for rice weed-management programs
Selected broadleaf weeds	Program-fit direction according to approved claim
Selected aquatic weeds	Rice paddy aquatic weed direction where registered
Mixed paddy weed pressure	Suitable for markets needing a Group 2 rice herbicide option

The product should not be described as controlling all rice weeds. Actual target spectrum must follow approved local label claims.

Suitable Crops and Application Areas

Paddy Rice

Penoxsulam 25 g/L OD is mainly positioned for paddy rice weed-management programs.

It can be reviewed for local markets where rice production needs a Group 2 herbicide direction for selected mixed weed pressure.

Transplanted Rice and Direct-Seeded Rice Review

Penoxsulam 25 g/L OD may be reviewed for transplanted rice or direct-seeded rice systems where local registration supports its use.

Final suitability depends on local label directions, rice variety, crop stage, water condition, soil condition, and application timing.

Local Market Application Review

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

• Rice cultivation system
• Main target weed spectrum
• Weed growth stage
• Application window
• Water-management practice
• Existing Group 2 resistance pressure
• Local registration requirements
• Distributor product portfolio position

This helps confirm whether Penoxsulam 25 g/L OD is suitable for the target market and local rice herbicide channel.

Application Guidance

Penoxsulam 25 g/L OD must be used according to local registration and approved label directions.

General review points include:

• Use only where locally registered

• Follow local safety, PHI, MRL, and environmental requirements

Final crop scope, target claim, dosage, timing, interval, PHI, MRL, safety requirement, and use restriction must follow local registration and approved label directions.

OD Formulation Features

OD means oil dispersion. Penoxsulam 25 g/L OD is an oil-based liquid formulation where the active ingredient is dispersed in an oil system.

The technical value of OD formulation is mainly reflected in dispersion performance, dilution behavior, and physical stability.

Key formulation features include:

• Oil-based dispersion system
• Dispersion stability
• Stable dilution behavior
• Physical stability during storage
• Active ingredient content control
• Batch consistency
• Flowability during handling
• Storage stability
• Leakage prevention
• Temperature control

For registration review, import cooperation, and distribution planning, OD formulation quality should be evaluated through product specification, sample support, formulation information, and batch quality confirmation.

Product Advantages

Focused Rice Herbicide Positioning

Penoxsulam 25 g/L OD has a clear position in paddy rice weed-management channels.

It is suitable for local markets that need a registered single-active rice herbicide direction for selected mixed weed pressure.

Single-Active Group 2 Direction

This product is based on Penoxsulam as the active ingredient.

It is different from mixed products that combine Penoxsulam with other herbicide groups. This makes the page positioning clear for registration review and portfolio planning.

Mixed Weed-Management Fit

Penoxsulam 25 g/L OD can support selected grasses, sedges, broadleaf weeds, and aquatic weed directions where approved by local registration.

Final weed claims must follow the approved local label.

OD Formulation Value

The oil dispersion formulation supports liquid formulation handling, dispersion performance, dilution behavior, and batch consistency.

This is important for professional rice herbicide channels that need stable product quality.

Registration Review Support

SunAgro Science can provide available product information to support local registration review, formulation evaluation, and market entry planning.

This helps local partners evaluate product feasibility before import and distribution cooperation.

SunAgro Branded Supply Direction

SunAgro Science supplies SunAgro branded Penoxsulam 25 g/L OD for long-term cooperation with qualified local importers, distributors, registration companies, agricultural retailers, and crop protection channels.

Difference Between Penoxsulam 25 g/L OD and Penoxsulam 30 g/L + Cyhalofop-Butyl 200 g/L OD

Penoxsulam 25 g/L OD and Penoxsulam 30 g/L + Cyhalofop-Butyl 200 g/L OD are not the same product direction.

Item	Penoxsulam 25 g/L OD	Penoxsulam 30 g/L + Cyhalofop-Butyl 200 g/L OD
Product Type	Single-active rice herbicide	Mixed active rice herbicide
Active Ingredients	Penoxsulam	Penoxsulam + Cyhalofop-Butyl
HRAC Group	Group 2	Group 2 + Group 1
Main Position	Single-active ALS-inhibiting rice herbicide	Mixed weed-management direction with added ACCase grass weed activity
Main Target Direction	Selected grasses, sedges, broadleaf weeds, and aquatic weeds where approved	Mixed paddy weeds with stronger grass weed program positioning depending on local label

Because both products are Group 2 herbicides, they do not provide different resistance-management modes.

They should not be rotated only with each other for resistance management. The final product choice should be based on local registration, weed spectrum, crop safety, formulation preference, and resistance-management planning.

Crop Safety, Resistance Management, and Use Precautions

Penoxsulam 25 g/L OD must be used with careful crop safety and resistance-management review.

Crop safety may be affected by:

• Rice variety
• Rice growth stage
• Water level
• Soil condition
• Application timing
• Temperature
• Formulation use practice
• Approved local label restrictions

Penoxsulam is a Group 2 ALS / AHAS inhibitor. Repeated use of Group 2 herbicides may increase resistance pressure, especially in rice fields with long-term ALS herbicide use.

For resistance management, local programs should consider:

• Rotation with herbicides from different HRAC groups where approved
• Avoiding repeated Group 2 herbicide use alone year after year
• Monitoring fields with known ALS resistance pressure
• Combining chemical programs with field and water management
• Following local resistance-management guidance

Penoxsulam 25 g/L OD should not be promoted as a resistance-proof solution. It is one product option within a broader rice weed-management program.

Final crop scope, target claim, dosage, timing, interval, PHI, MRL, safety requirement, and use restriction must follow local registration and approved label directions.
