Mesosulfuron-Methyl 3% + Iodosulfuron-Methyl Sodium 0.6% + Mefenpyr-Diethyl 5% WDG

POMAIS Mesosulfuron-Methyl 3% + Iodosulfuron-Methyl Sodium 0.6% + Mefenpyr-Diethyl 5% WDG is a selective post-emergence herbicide developed for the control of selected annual grass weeds and broadleaf weeds in approved wheat programs.

Mesosulfuron-Methyl and Iodosulfuron-Methyl Sodium are both HRAC Group 2 ALS inhibitors. They stop susceptible weeds from producing essential branched-chain amino acids, causing growth to cease before visible yellowing and decline develop.

Mefenpyr-Diethyl is included as a cereal safener, not as a third herbicide active ingredient. It supports crop tolerance under approved use conditions but does not add another mode of action or eliminate the risks caused by excessive rates, spray overlap, crop stress or incorrect application timing.

We supply this WDG formulation for agrochemical importers, wheat-input distributors, registration companies and crop protection brands. Packaging, labels, technical documents and commercial specifications are reviewed according to the destination market.

What Is Mesosulfuron + Iodosulfuron WDG?

This product is a post-emergence cereal herbicide containing two sulfonylurea herbicidal active ingredients and one crop safener.

Its primary role is to control susceptible weeds after they have emerged in wheat fields.

The product is mainly positioned for:

  • Annual grass weed management
  • Selected broadleaf weed control
  • Early post-emergence treatment
  • Wheat-production systems
  • Fields where Group 2 herbicides remain effective
  • Programs requiring a dry WDG formulation

It is not a pre-emergence residual herbicide.

It should not be described as a three-mode-of-action product because Mefenpyr-Diethyl does not control weeds.

Both herbicidal components belong to the same HRAC group. The combination may broaden the weed spectrum within Group 2, but it does not provide two independent resistance-management mechanisms.

Importers developing a wider cereal portfolio can connect this product with relevant selective herbicide products.

How Does the Herbicide Work?

Mesosulfuron-Methyl Mode of Action

Mesosulfuron-Methyl belongs to HRAC Group 2.

It inhibits the acetolactate synthase enzyme, also known as ALS or AHAS.

This enzyme is required for the production of essential branched-chain amino acids, including:

  • Valine
  • Leucine
  • Isoleucine

After susceptible weeds absorb the herbicide, amino acid production is disrupted.

The practical sequence is:

Foliar uptake → ALS inhibition → cell division stops → weed growth ceases → yellowing and decline develop

Mesosulfuron-Methyl is systemic. It can move from treated foliage toward active growing points in susceptible weeds.

Its primary commercial value in this premix is the control of selected annual grass weeds in wheat.

Iodosulfuron-Methyl Sodium Mode of Action

Iodosulfuron-Methyl Sodium is also an HRAC Group 2 ALS inhibitor.

It acts through the same broad biochemical mechanism as Mesosulfuron-Methyl but contributes a different activity profile against selected grass and broadleaf weeds.

Within the premix, it may support:

  • Broader annual grass weed activity
  • Additional control of selected broadleaf weeds
  • More complete post-emergence weed-spectrum coverage
  • Consistent activity across mixed susceptible populations

The two active ingredients remain part of the same resistance group.

Changing from Mesosulfuron-Methyl to Iodosulfuron-Methyl Sodium is not considered a mode-of-action rotation.

Combined Group 2 Activity

The combined herbicidal action can be understood as:

Mesosulfuron-Methyl provides strong grass-weed direction → Iodosulfuron-Methyl Sodium broadens selected grass and broadleaf activity → susceptible weeds stop growing after ALS inhibition

Visual symptoms do not normally appear immediately.

After application:

  • Weed growth may stop first
  • Young leaves may become pale
  • Growing points may yellow
  • Tissue decline develops gradually
  • Complete control may require several days or longer

Cold weather, drought stress and advanced weed growth stages may slow visible symptom development.

The product should not be presented as a fast contact herbicide or an instant leaf-burning treatment.

What Does Mefenpyr-Diethyl Do?

Mefenpyr-Diethyl is a herbicide safener.

It is included to support cereal crop tolerance to the herbicidal active ingredients.

Safener Function

Mefenpyr-Diethyl helps the crop metabolize the herbicidal components more rapidly under approved conditions.

This creates a greater selectivity difference between:

  • The protected cereal crop
  • Susceptible grass and broadleaf weeds

The safener does not neutralize the herbicides inside the spray tank.

It supports crop metabolism after application.

Mefenpyr-Diethyl Is Not a Herbicide

Mefenpyr-Diethyl:

  • Does not directly kill weeds
  • Does not expand the weed spectrum
  • Does not create a third mode of action
  • Does not control resistant weeds
  • Does not improve weed control by itself
  • Does not make unregistered crops tolerant

The product therefore contains:

  • Two herbicidal active ingredients
  • One crop safener
  • One herbicide mode-of-action group

What the Safener Cannot Prevent

Mefenpyr-Diethyl cannot fully protect the crop from:

  • Excessive application rates
  • Spray overlap
  • Incorrect crop use
  • Application outside the approved growth stage
  • Severe frost
  • Drought stress
  • Waterlogging
  • Root disease
  • Serious nutrient deficiency
  • Unsafe tank mixtures
  • Incorrect adjuvants
  • Sensitive varieties outside the registration data

Crop safety depends on the complete application program.

Target Grass and Broadleaf Weeds

This formulation is primarily positioned for annual grass weeds in wheat, with additional activity against selected annual broadleaf weeds.

Exact weed claims must follow the destination-market label.

Weed Direction Typical Examples Product Positioning
Annual Grass Weeds Black-grass, annual ryegrass, wild oats, windgrass and selected brome species Primary commercial target
Small Annual Grasses Annual meadow-grass and other labeled species Early post-emergence control
Selected Broadleaf Weeds Chickweed, cleavers, field pansy, mayweed species and shepherd’s purse Additional spectrum support
Volunteer Crops Volunteer oilseed rape or other labeled volunteers Product-specific claim
Group 2-Resistant Weeds Resistant black-grass, ryegrass or wild oats Control may be poor or absent
Large or Tillered Grass Weeds Advanced grass weeds Reduced reliability

Annual Grass Weeds

Annual grasses are the central use direction for this product.

Potential target directions may include:

  • Black-grass
  • Annual ryegrass
  • Wild oats
  • Windgrass
  • Annual meadow-grass
  • Selected brome species
  • Other labeled cereal grass weeds

The best results are generally obtained when:

  • The correct weed species is identified
  • Weeds are young
  • Weeds are actively growing
  • The full registered rate is used
  • Coverage is uniform
  • Group 2 resistance is not present
  • Weather conditions support active growth

Advanced tillering, drought stress or established resistance can reduce control.

Selected Broadleaf Weeds

Iodosulfuron-Methyl Sodium may extend the spectrum to selected annual broadleaf weeds.

Potential directions may include:

  • Chickweed
  • Cleavers
  • Field pansy
  • Mayweed species
  • Shepherd’s purse
  • Volunteer oilseed rape
  • Other label-listed weeds

Broadleaf activity should not be generalized to every weed species.

Large, mature or resistant weeds may require a different treatment strategy.

Resistant Grass Weeds

The product should not be promoted for Group 2-resistant grass weeds.

If a population is resistant to ALS inhibitors, both Mesosulfuron-Methyl and Iodosulfuron-Methyl Sodium may provide insufficient control.

Possible resistance indicators include:

  • Healthy weeds surviving among controlled weeds
  • Repeated failure in the same field
  • Previous heavy reliance on sulfonylurea herbicides
  • Surviving black-grass or ryegrass producing seed
  • Poor control under otherwise suitable conditions

Suspicious populations should be tested where resistance-testing services are available.

Suitable Crops and Market Positioning

The principal crop direction is wheat.

Other cereal uses should only be included where supported by the exact product registration.

Winter Wheat

Winter wheat is the strongest commercial positioning for this formulation.

The product may support approved programs for:

  • Annual grass weed control
  • Selected broadleaf weed control
  • Early spring post-emergence applications
  • Autumn post-emergence treatment where registered
  • Resistance-integrated cereal programs

Use must consider:

  • Wheat growth stage
  • Variety
  • Crop vigor
  • Weed growth stage
  • Temperature
  • Soil moisture
  • Previous herbicide use
  • Resistance history
  • Required adjuvant

For broader crop-program development, buyers can review our wheat weed management solutions.

Spring Wheat and Durum Wheat

Do not assume that a winter wheat registration automatically covers spring wheat or durum wheat.

Crop tolerance may differ according to:

  • Wheat type
  • Variety
  • Growth pattern
  • Environmental conditions
  • Application timing
  • Safener response

These uses should only appear on the final commercial label where supported by registration data.

Rye and Triticale

Some Mesosulfuron + Iodosulfuron products may be registered for rye or triticale.

However, crop authorization varies by formulation and country.

The product should not be promoted for rye or triticale unless:

  • The exact 3% + 0.6% + 5% WDG formulation is registered
  • Crop selectivity has been demonstrated
  • The label includes the crop
  • The application timing is defined

Barley and Oats

Barley and oats should not be added as default crop directions.

Different cereal species can vary significantly in their tolerance to ALS-inhibiting herbicides.

A wheat safener package does not automatically make the product safe for all cereal crops.

When Should the Herbicide Be Applied?

The product should be applied post-emergence, when the crop and weeds are within the approved growth stages.

Apply to Young, Actively Growing Weeds

Young weeds are generally easier to control because they have:

  • Smaller root systems
  • Fewer tillers
  • More active growth
  • Better foliar uptake
  • Less stored energy
  • Greater dependence on growing points

Waiting until grass weeds have developed multiple tillers can reduce reliability.

Confirm the Wheat Growth Stage

The approved label determines:

  • Earliest crop stage
  • Latest crop stage
  • Seasonal application window
  • Maximum number of applications
  • Permitted autumn or spring use
  • Required interval from other treatments

Do not apply based only on the weed stage.

The wheat crop must also be within the permitted growth window.

Apply Under Active-Growth Conditions

Performance is generally more reliable when:

  • Weeds are actively growing
  • Soil moisture is adequate
  • Temperatures are suitable
  • The crop is not severely stressed
  • Heavy frost is not expected
  • Rain will not remove the spray before the required interval

Cold Conditions

Low temperatures can slow:

  • Herbicide uptake
  • Herbicide movement
  • ALS inhibition symptoms
  • Weed yellowing
  • Final decline

Slow symptom development does not automatically indicate treatment failure.

However, applications outside the approved temperature range may reduce both weed control and crop selectivity.

Drought and Water Stress

Drought-stressed weeds may have:

  • Reduced leaf activity
  • Thicker wax layers
  • Slower growth
  • Lower herbicide uptake
  • Reduced translocation

Severely stressed wheat may also be more vulnerable to temporary crop effects.

Application Guidance

The following principles do not replace the registered product label.

1. Identify the Weed Species

Before treatment, confirm:

  • Dominant grass weeds
  • Broadleaf weeds
  • Weed growth stage
  • Tiller number
  • Previous resistance problems
  • Surviving weeds from earlier treatments

Do not select the product only because a field contains “grass weeds.”

Different grass species may respond differently.

2. Review Group 2 Resistance History

Check whether the field or region has documented resistance to:

  • Mesosulfuron
  • Iodosulfuron
  • Sulfonylurea herbicides
  • Other ALS inhibitors

Where resistance is established, choose a program with effective alternative modes of action.

3. Confirm Crop Condition

Avoid application to wheat under severe stress from:

  • Frost
  • Drought
  • Waterlogging
  • Nutrient deficiency
  • Root disease
  • Insect damage
  • Extreme temperature changes
  • Soil compaction
  • Previous herbicide injury

4. Measure the WDG Accurately

This is a low-dose herbicide formulation.

Accurate measurement is essential.

Use:

  • Calibrated scales
  • Clean, dry measuring tools
  • Correct package size
  • Full product rate calculations
  • Accurate field-area measurement

Do not estimate the amount by volume unless the label provides a validated volumetric method.

5. Prepare the Spray Tank Correctly

Where permitted by the label:

  1. Clean the spray tank.
  2. Fill part of the tank with clean water.
  3. Start agitation.
  4. Add the WDG product slowly.
  5. Allow the granules to wet and disperse.
  6. Add the required adjuvant in the approved sequence.
  7. Add compatible partners only where permitted.
  8. Complete filling with water.
  9. Maintain agitation during application.
  10. Use the mixture within the recommended period.

6. Apply Uniformly

Check:

  • Nozzle condition
  • Spray pressure
  • Boom height
  • Ground speed
  • Water volume
  • Droplet size
  • Spray pattern
  • Field boundaries

Uneven application may produce poor weed control or crop injury.

7. Avoid Spray Overlap

Overlap can increase:

  • Crop yellowing
  • Temporary stunting
  • Selectivity risk
  • Residue exposure
  • Rotational-crop concerns

Pay close attention near field edges, headlands and obstacles.

Crop Selectivity and Injury Risks

Crop safety depends on the interaction between:

  • The two herbicides
  • Mefenpyr-Diethyl
  • Wheat variety
  • Crop stage
  • Weather
  • Application rate
  • Adjuvant
  • Tank-mix partners
  • Crop health

How Mefenpyr Supports Wheat Tolerance

Mefenpyr-Diethyl helps the cereal crop metabolize the herbicidal components more quickly than susceptible weeds.

This may reduce the duration and intensity of herbicide exposure inside the crop.

It does not make the crop completely insensitive.

Temporary Crop Effects

Under some conditions, treated wheat may show temporary symptoms such as:

  • Mild yellowing
  • Short-term growth slowing
  • Reduced vigor
  • Leaf discoloration

Temporary symptoms may be more likely after:

  • Cold conditions
  • Large temperature changes
  • Crop stress
  • Spray overlap
  • Strong adjuvants
  • Complex tank mixtures
  • Application near the edge of the crop window

The crop should be monitored according to the registered label and local agronomic guidance.

Conditions That Increase Injury Risk

Risk Factor Why It Matters
Frost Before or After Treatment Reduces crop metabolism and safener response
Drought Stress Weakens crop recovery and alters uptake
Waterlogging Damages roots and reduces crop vigor
Nutrient Deficiency Limits the crop’s ability to recover
Root Disease Increases physiological stress
Spray Overlap Increases the herbicide dose
Incorrect Adjuvant May increase penetration and crop exposure
Unapproved Tank Mix May reduce selectivity
Sensitive Variety Crop tolerance may differ
Application Outside Label Timing Increases crop-safety uncertainty

WDG Formulation Features

WDG means Water-Dispersible Granule.

The granules are designed to wet, disintegrate and disperse in water, forming a spray suspension.

They do not necessarily dissolve completely like a soluble powder.

Practical Advantages of WDG

A WDG formulation may provide:

  • Compact solid packaging
  • Lower liquid leakage risk
  • Efficient export storage
  • Convenient small-pack distribution
  • Accurate factory-controlled active ingredient ratios
  • Reduced dependence on liquid bottles
  • Easier carton and pallet planning
  • Good suitability for moisture-barrier sachets

Key WDG Quality Parameters

Quality Parameter Buyer Relevance
Mesosulfuron-Methyl Content Confirms the declared 3% content
Iodosulfuron-Methyl Sodium Content Confirms the declared 0.6% content
Mefenpyr-Diethyl Content Confirms the declared 5% safener content
Content Uniformity Critical for a low-dose multi-component formulation
Wettability Influences how quickly granules enter the spray water
Disintegration Time Influences mixing efficiency
Suspensibility Helps maintain uniform spray concentration
Wet Sieve Residue Helps reduce nozzle-blockage risk
Persistent Foam Influences spray-tank filling
Moisture Content Affects stability and caking
Attrition Resistance Reduces dust formation during transport
Bulk Density Influences filling and package volume
Caking Resistance Supports storage performance
Pack-Weight Accuracy Essential for low-dose field application

Content Uniformity

This formulation contains active components at relatively low percentages.

Uniform distribution inside every batch and package is therefore important.

Poor uniformity may result in:

  • Inconsistent weed control
  • Uneven safener delivery
  • Crop-selectivity variation
  • Pack-to-pack performance differences
  • Registration non-compliance

Quality control should confirm all three components, not only the total product weight.

Moisture Protection

WDG granules can absorb moisture if packaging is inadequate.

Moisture exposure may cause:

  • Caking
  • Soft granules
  • Slower disintegration
  • Reduced flow
  • Package damage
  • Stability problems

Packaging should therefore use an appropriate moisture barrier.

WDG vs OD Formulation

POMAIS also supplies a liquid OD product containing Mesosulfuron-Methyl, Iodosulfuron-Methyl Sodium and Mefenpyr-Diethyl.

The two formulations serve similar weed-management directions but have different physical and commercial characteristics.

Comparison Factor 3% + 0.6% + 5% WDG 10 + 2 + 30 g/L OD
Physical Form Dry water-dispersible granule Liquid oil dispersion
Herbicidal Active Ratio 5:1 5:1
Safener Specification 5% 30 g/L
Mixing Behavior Granules wet, disintegrate and suspend Oil dispersion dilutes in water
Packaging Sachet, bag or solid-product container Bottle or liquid container
Leakage Risk No liquid leakage Requires liquid packaging integrity
Main Quality Focus Uniformity, wettability, disintegration and moisture control Dispersion stability, viscosity and bottle compatibility
Storage Requirement Protect from moisture Protect from temperature extremes and separation
Registration Identity Separate WDG registration Separate OD registration
Buyer Positioning Dry-formulation distribution channel Liquid-formulation distribution channel

The WDG and OD products cannot use the same application rate, label or product specification.

Buyers comparing dry and liquid formats can review our Mesosulfuron + Iodosulfuron OD herbicide.

Tank Mixing and Adjuvant Requirements

Some Mesosulfuron + Iodosulfuron labels require a specific surfactant, oil or adjuvant system.

The exact requirement must come from the registered label.

Do not assume that all adjuvants are interchangeable.

Adjuvant Selection

The wrong adjuvant may cause:

  • Reduced weed control
  • Excessive crop uptake
  • Temporary crop injury
  • Spray incompatibility
  • Excessive foam
  • Poor droplet behavior

Confirm:

  • Adjuvant type
  • Adjuvant rate
  • Mixing order
  • Water volume
  • Temperature restrictions
  • Crop condition
  • Tank-mix partners

Tank-Mix Compatibility

Tank mixing may be influenced by:

  • Water hardness
  • Water pH
  • Fertilizer salts
  • Partner formulation
  • Mixing order
  • Adjuvant
  • Spray temperature
  • Number of products in the tank

Conduct a small compatibility test for unfamiliar mixtures.

Physical compatibility does not guarantee crop safety or biological performance.

Liquid Fertilizers

Do not assume the product can be mixed safely with liquid nitrogen or foliar fertilizers.

High salt concentration or fertilizer stress may increase crop injury.

Use only where the exact label and local recommendations permit the mixture.

Resistance Management

Mesosulfuron-Methyl and Iodosulfuron-Methyl Sodium are both HRAC Group 2 herbicides.

The premix therefore has one herbicide mode-of-action group.

Mefenpyr-Diethyl is a safener and does not provide a resistance-management mode of action.

Group 2 Resistance Risk

Repeated reliance on ALS-inhibiting herbicides can select resistant weed populations.

Resistance has been documented in important cereal grass weeds in multiple markets.

Potential high-risk weeds include:

  • Black-grass
  • Annual ryegrass
  • Wild oats
  • Brome species
  • Other repeatedly treated cereal weeds

Resistance-Management Principles

  • Confirm the weed species.
  • Review field resistance history.
  • Use the complete registered rate.
  • Apply to young weeds.
  • Avoid repeated Group 2 treatments.
  • Use effective pre-emergence residual herbicides where registered.
  • Rotate with herbicides from other HRAC groups.
  • Rotate crops.
  • Use competitive wheat varieties.
  • Adjust sowing dates where agronomically suitable.
  • Increase crop competition where practical.
  • Prevent survivors from producing seed.
  • Clean harvest and cultivation equipment between infested fields.
  • Test suspicious weed populations.

Surviving Weeds

After treatment, inspect the field for:

  • Healthy survivors
  • Uneven control
  • Species-specific failure
  • Survivors in correctly treated areas
  • New seed production

Do not repeatedly treat suspected resistant weeds with another Group 2 herbicide.

Changing the product name does not change the mode of action.

Rotational Crops and Soil Considerations

Sulfonylurea herbicide persistence can be influenced by:

  • Soil pH
  • Soil moisture
  • Temperature
  • Organic matter
  • Application rate
  • Rainfall
  • Time between treatment and planting

Some rotational crops may be sensitive to residues.

Soil pH

High soil pH may slow the breakdown of some sulfonylurea herbicides.

This can increase the risk to sensitive rotational crops.

Do not publish one universal pH limit or plant-back interval without the exact product label.

Dry Conditions

Dry conditions may delay herbicide degradation.

Where rainfall is limited, residues may remain active longer than expected.

Plant-Back Restrictions

Rotational crop restrictions must be taken from the exact registered label.

They may differ for:

  • Oilseed rape
  • Sugar beet
  • Legumes
  • Maize
  • Sunflower
  • Vegetables
  • Other sensitive crops

The buyer should confirm the intended crop rotation during registration and label development.

Equipment Cleaning

Spray equipment must be cleaned thoroughly after use.

Small residues of Group 2 herbicides may damage sensitive broadleaf crops treated later.

Cleaning should include:

  • Spray tank
  • Pumps
  • Hoses
  • Filters
  • Nozzles
  • Boom ends
  • Induction systems

Follow the approved tank-cleaning procedure.

Simple water draining may not remove all residues.

Safety and Environmental Precautions

Handle the product according to the final SDS and approved label.

Operator Safety

  • Wear the required protective clothing.
  • Avoid skin and eye contact.
  • Avoid inhaling granule dust or spray mist.
  • Do not eat, drink or smoke during handling.
  • Wash hands and exposed skin after use.
  • Remove contaminated clothing.
  • Keep unauthorized people away from the mixing area.
  • Follow the approved re-entry interval.
  • Do not reuse empty pesticide packaging.

WDG Dust Control

Although WDG products generally create less dust than wettable powders, damaged granules may still produce fine particles.

Avoid:

  • Dropping bags unnecessarily
  • Pouring from excessive height
  • Handling broken packaging
  • Working in strong wind
  • Breathing dust during mixing

Protect Non-Target Plants

Spray drift may damage:

  • Broadleaf crops
  • Oilseed crops
  • Sugar beet
