Propanil 360g/L + Triclopyr 72g/L EC: Selective Post-Emergence Herbicide for Rice

Introduction

Propanil 360g/L + Triclopyr 72g/L EC is a selective post-emergence herbicide combination mainly positioned for use in registered rice production systems.

The formulation combines two herbicides with different activity profiles:

• Propanil 360g/L — mainly contact activity, especially against susceptible annual grasses
• Triclopyr 72g/L — systemic synthetic auxin activity, mainly against susceptible broadleaf plants and some sedges

This gives the product a broader post-emergence control profile than relying on one active ingredient alone.

Its core positioning is:

Rice Herbicide + Post-Emergence Control + Grass, Broadleaf and Sedge Management + Dual Mode of Action

General Applications

This formulation is mainly associated with rice production, where registered.

Typical application positioning may include control of susceptible:

• Annual grasses
• Broadleaf plants
• Certain sedges

Propanil has a long history of use in rice for post-emergence grass management, while triclopyr is used for susceptible broadleaf and sedge species in registered rice systems.

The exact crop stage, target species and application timing should always follow the locally approved label.

What Does 360g/L + 72g/L EC Mean?

The formulation contains:

Propanil — 360g/L

Triclopyr — 72g/L

Total declared active ingredient concentration:

432g/L

EC means:

Emulsifiable Concentrate

The formulation is designed to form an emulsion when diluted with water according to label directions.

For professional buyers, EC formulations are widely recognized and offer flexible packaging and handling options.

Mode of Action

Propanil

Propanil is a selective herbicide with mainly contact activity.

It acts by inhibiting photosynthesis in susceptible plants. Because it is mainly contact-active, good spray coverage is important.

Its role in this mixture is primarily to provide control of susceptible grass species in rice.

Triclopyr

Triclopyr is a systemic synthetic auxin herbicide.

It belongs to HRAC/WSSA Group 4.

After absorption, Triclopyr moves within susceptible plants and disrupts normal auxin-regulated growth. This causes abnormal cell development, tissue distortion and eventual decline.

Its role in the mixture is mainly to broaden control toward susceptible broadleaf plants and some sedges.

Why Combine Propanil and Triclopyr?

The main advantage is complementary activity.

Propanil contributes strong contact performance against susceptible grass species.

Triclopyr contributes systemic activity against susceptible broadleaf plants and certain sedges.

The combination can therefore be positioned as:

Grass Control + Broadleaf Control + Sedge Control

This is especially useful in rice fields where mixed plant populations are present.

Rice Field Positioning

In rice production, mixed target pressure is common.

A field may contain:

• Barnyardgrass-type grasses
• Broadleaf species
• Sedge species

A single active ingredient may not always provide adequate control across all target groups.

By combining Propanil and Triclopyr, the formulation is designed to provide broader post-emergence coverage where locally registered.

Post-Emergence Use

This product is mainly positioned for post-emergence application.

That means target plants have already emerged before treatment.

Post-emergence performance depends strongly on:

• Target plant growth stage
• Plant size
• Spray coverage
• Rice growth stage
• Water management
• Environmental conditions
• Resistance status

Younger, actively growing target plants are generally easier to control than large, mature plants.

Grass Control

Propanil is best known for activity against susceptible grass species in rice.

Typical target groups may include:

• Barnyardgrass
• Echinochloa species
• Other susceptible annual grasses

Because Propanil is mainly contact-active, thorough leaf coverage is important for good performance.

Broadleaf and Sedge Control

Triclopyr helps broaden the spectrum of the mixture.

As a systemic synthetic auxin, it can provide activity against susceptible:

• Broadleaf plants
• Certain sedges

This gives the combination a more complete post-emergence profile than a grass-only product.

Water Management Considerations

Water management is an important part of rice herbicide performance.

Depending on the local label, growers may need to manage field water before and after application.

Incorrect water depth or movement can reduce treatment consistency or increase crop-safety risk.

For this reason, exact water-management instructions should always come from the locally registered label.

Crop Safety

Selective herbicides must be used at the correct crop stage.

Rice tolerance can be affected by:

• Growth stage
• Stress
• Temperature
• Water conditions
• Application timing
• Rate
• Interactions with other crop-protection products

Applying outside the registered crop stage can increase the risk of crop injury.

Resistance Management

Resistance management is important for all herbicide programs.

Triclopyr belongs to Group 4, while Propanil has a different herbicidal mode of action.

Using two active ingredients can reduce dependence on one mode of action, but it does not eliminate resistance risk.

Good resistance-management practices include:

• Rotating with effective herbicides from different groups
• Using mixtures only where both actives are effective
• Monitoring fields after treatment
• Preventing surviving plants from reproducing
• Integrating cultural and mechanical management where practical

Changing only the brand name while using the same mode of action is not a true resistance-management strategy.

Formulation Quality

Professional buyers should evaluate more than active ingredient concentration.

Important quality parameters include:

• Propanil content
• Triclopyr content
• Appearance
• Emulsion stability
• pH
• Storage stability
• Packaging compatibility
• Batch consistency

Recommended commercial documents include:

• COA — Certificate of Analysis
• SDS — Safety Data Sheet
• TDS — Technical Data Sheet
• Product specification
• Registration-support documents
