Main Functions

This formulation is mainly positioned for maize herbicide programs that need grass, broadleaf, and residual support in one structured application direction.

It is not positioned as a universal maize herbicide or a full-season weed-control guarantee.

Main functions include:

• Supports early weed-pressure management in maize
• Helps manage selected annual grass weeds where locally approved
• Supports selected broadleaf weed programs in maize
• Provides residual-support direction through soil-applied components
• Fits pre-emergence and early post-emergence maize programs
• Supports local partners building a three-active maize herbicide portfolio
• Provides a Group 15 + Group 27 + Group 5 program direction for registration review

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

Mode of Action and Three-Active Value

This product combines three active ingredients with different herbicide group directions.

The combined formula is designed for maize weed-management programs where early annual grass pressure, selected broadleaf weeds, and residual support are all important.

S-Metolachlor: Group 15 Residual Grass Direction

S-Metolachlor belongs to HRAC Group 15.

It is associated with inhibition of very long-chain fatty acid synthesis. In this formula, its role is mainly to support annual grass weed management and soil residual activity where locally approved.

S-Metolachlor is important for maize programs that need early grass weed pressure management during crop establishment.

Mesotrione: Group 27 HPPD Direction

Mesotrione belongs to HRAC Group 27.

It works as an HPPD inhibitor. In maize herbicide programs, Mesotrione is mainly valued for selected broadleaf weed activity and program expansion where local registration supports its use.

Visible weed response may develop gradually and depends on weed species, weed stage, application timing, field condition, and local use practice.

Terbuthylazine: Group 5 PSII Direction

Terbuthylazine belongs to the triazine herbicide direction and is associated with HRAC Group 5 PSII inhibition.

In this formula, Terbuthylazine supports selected broadleaf weed control and residual activity where locally approved.

Its role should be reviewed together with local registration, soil condition, crop safety, and resistance-management needs.

Combined Value in Maize Weed Programs

This product provides three herbicide group directions in one SE formulation.

It can support registered maize weed-management programs where annual grasses, selected broadleaf weeds, and residual-support needs appear together.

Three active ingredients do not mean resistance-proof control. Repeated use of the same program can still increase resistance pressure.

Target Weed Directions

S-Metolachlor 375 g/L + Mesotrione 37.5 g/L + Terbuthylazine 125 g/L SE is positioned for selected maize-field weed directions where approved by local registration.

Target Direction	Practical Positioning
Selected annual grasses	Main grass weed direction where locally approved
Early grass infestations	Important during maize establishment
Selected broadleaf weeds	Main broadleaf direction according to local label
Small broadleaf weeds	Better fit for early post-emergence review
Mixed grass and broadleaf pressure	Key program-fit direction for maize fields
Early-season weed pressure	Suitable for pre-emergence and early post-emergence planning
Residual-support programs	Useful where local registration supports soil residual activity

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

Suitable Crops and Application Areas

Maize / Corn

S-Metolachlor 375 g/L + Mesotrione 37.5 g/L + Terbuthylazine 125 g/L SE is mainly positioned for maize / corn weed-management programs.

It can be reviewed where local registration supports the use of this three-active herbicide direction in maize.

Pre-Emergence Maize Programs

This product can be reviewed for pre-emergence maize programs where early annual grasses and selected broadleaf weeds need residual-support planning.

Final suitability depends on soil condition, moisture, rainfall pattern, crop system, and local label directions.

Early Post-Emergence Maize Programs

This product can also be reviewed for early post-emergence maize programs according to local registration.

The final application window depends on maize crop stage, weed stage, local climate, and approved label requirements.

Local Market Application Review

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

• Maize planting system
• Target weed spectrum
• Annual grass pressure
• Broadleaf weed pressure
• Soil condition
• Rainfall and irrigation pattern
• Crop stage and application timing
• Herbicide resistance pressure
• Local registration requirements
• Distributor portfolio position

This helps confirm whether this SE formulation is suitable for the target market and local maize herbicide channel.

Application Guidance

S-Metolachlor 375 g/L + Mesotrione 37.5 g/L + Terbuthylazine 125 g/L SE must be used according to local registration and approved label directions.

General review points include:

• Use only where locally registered
• Confirm maize crop stage before application
• Confirm target weed species and weed stage
• Review pre-emergence and early post-emergence timing
• Review soil condition and moisture status
• Confirm spray volume and dilution practice according to the approved label
• Avoid drift to sensitive crops and non-target areas
• Do not apply to stressed maize unless the approved label allows it
• Avoid repeated use of the same Group 15 + 27 + 5 program without rotation
• Follow local PHI, MRL, safety, 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.

SE Formulation Features

SE means suspo-emulsion. This formulation type combines suspended solid particles and emulsified liquid components in one water-based system.

For this product, SE formulation helps combine S-Metolachlor, Mesotrione, and Terbuthylazine in a practical liquid formulation for maize herbicide channels.

Key formulation features include:

• Suspo-emulsion formulation
• Suitable for multi-active formulations with different physical properties
• Dispersion stability
• Emulsion stability
• Suspension stability
• Stable dilution behavior
• Particle size control
• Physical stability during storage
• Flowability during handling
• Batch consistency
• Leakage prevention
• Temperature control

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

Product Advantages

Three-Active Maize Herbicide Direction

This formulation combines S-Metolachlor, Mesotrione, and Terbuthylazine in one maize herbicide product.

It supports local markets that need a structured maize weed-management program direction rather than a single-active herbicide option.

Group 15 + Group 27 + Group 5 Structure

The product provides three herbicide group directions:

• S-Metolachlor: Group 15
• Mesotrione: Group 27
• Terbuthylazine: Group 5

This structure can support program review where local registration allows the use of multiple herbicide groups in maize.

Pre and Early Post Program Fit

The product is suitable for markets reviewing pre-emergence and early post-emergence maize herbicide directions.

It should be positioned according to approved local crop stage, weed stage, soil condition, and application timing.

Grass and Broadleaf Program Coverage

This SE formulation supports selected annual grass and selected broadleaf weed directions where locally approved.

It should not be promoted as controlling all maize weeds.

SE Formulation Value

SE formulation supports complex multi-active formulation design and liquid field handling.

It is especially relevant where different active ingredients need to be combined into one stable liquid formulation system.

Difference Between S-Metolachlor + Mesotrione + Terbuthylazine SE and S-Metolachlor + Mesotrione SE

S-Metolachlor + Mesotrione + Terbuthylazine SE and S-Metolachlor + Mesotrione SE are both maize herbicide directions, but their composition and program role are different.

Item	S-Metolachlor + Mesotrione + Terbuthylazine SE	S-Metolachlor + Mesotrione SE
Active Ingredients	S-Metolachlor + Mesotrione + Terbuthylazine	S-Metolachlor + Mesotrione
HRAC Groups	Group 15 + Group 27 + Group 5	Group 15 + Group 27
Main Position	Three-active maize herbicide direction	Two-active maize herbicide direction
Program Role	Grass, broadleaf, and residual-support direction	Grass residual + HPPD broadleaf direction
Terbuthylazine Role	Included as Group 5 triazine direction	Not included
Formulation Position	Three-active SE formulation	Two-active SE or other formulation direction depending on product

The three-active SE product is more suitable where local markets need a Group 15 + Group 27 + Group 5 maize herbicide direction.

The two-active product is more suitable where the target market does not require a Group 5 triazine component or where local registration prefers a simpler formula.

Difference Between S-Metolachlor + Mesotrione + Terbuthylazine SE and Mesotrione 10% OD

This SE product and Mesotrione 10% OD have different product roles.

Item	S-Metolachlor + Mesotrione + Terbuthylazine SE	Mesotrione 10% OD
Active Ingredients	S-Metolachlor + Mesotrione + Terbuthylazine	Mesotrione
Product Type	Three-active maize herbicide	Single-active HPPD herbicide
HRAC Groups	Group 15 + Group 27 + Group 5	Group 27
Main Position	Pre-emergence and early post-emergence maize program direction	Single-active HPPD broadleaf herbicide direction
Formulation	SE, suspo-emulsion	OD, oil dispersion
Program Value	Grass, broadleaf, and residual-support structure	HPPD-based direction without Group 15 or Group 5 components

Mesotrione 10% OD should not be treated as the same market position as this three-active SE formula.

The final product choice should depend on local registration, weed spectrum, application window, resistance-management need, and distributor portfolio planning.

Difference Between S-Metolachlor + Mesotrione + Terbuthylazine SE and Isoxadifen-ethyl + Tembotrione SC

Both products can be connected with maize herbicide programs, but their structure is different.

Item	S-Metolachlor + Mesotrione + Terbuthylazine SE	Isoxadifen-ethyl + Tembotrione SC
Main Structure	Three-active herbicide formula	Safener-supported HPPD herbicide formula
Active Herbicide Directions	Group 15 + Group 27 + Group 5	Group 27 herbicide direction
Safener Role	No safener positioning	Isoxadifen-ethyl acts as a safener
Main Crop Direction	Maize / Corn	Corn / Maize
Main Use Direction	Pre-emergence and early post-emergence program direction	Post-emergence corn herbicide direction
Formulation	SE, suspo-emulsion	SC, suspension concentrate
Portfolio Role	Grass, broadleaf, and residual-support maize program	Safener-supported HPPD post-emergence corn herbicide

Isoxadifen-ethyl should not be described as a main weed-control active ingredient. In that product direction, Tembotrione provides the Group 27 herbicide activity, while Isoxadifen-ethyl supports crop safety as a safener.

This SE product has a different program role because it combines S-Metolachlor, Mesotrione, and Terbuthylazine in one maize herbicide formulation.

Crop Safety, Resistance Management, and Use Precautions

S-Metolachlor 375 g/L + Mesotrione 37.5 g/L + Terbuthylazine 125 g/L SE must be used with careful crop safety and resistance-management review.

This product contains:

• S-Metolachlor: HRAC Group 15
• Mesotrione: HRAC Group 27
• Terbuthylazine: HRAC Group 5

Three groups can support program diversity, but they do not make the product resistance-proof.

Crop safety may be affected by:

• Maize variety
• Crop stage
• Soil texture
• Soil organic matter
• Soil moisture
• Rainfall after application
• Temperature
• Spray timing
• Tank-mix partner
• Local label restrictions

For resistance management, local programs should consider:

• Rotation with herbicides from different HRAC groups where approved
