Trifluralin
Active Ingredient & Classification
Trifluralin (CAS No. 1582-09-8; molecular formula C₁₃H₁₆F₃N₃O₄) is a member of the dinitroaniline herbicide class. It is classified in the recognized herbicide mode-of-action system as Group 3 (microtubule inhibitor).
Mode of Action — How It Works
When applied pre-emergence, Trifluralin forms a chemical barrier in the top soil layer. Germinating weed seeds or seedlings that attempt root penetration or hypocotyl elongation absorb the herbicide; the compound disrupts microtubule formation in dividing cells, inhibiting root and shoot development, causing seedlings to collapse or fail to emerge.
Key Benefits from the Chemistry
-
Effective at moderate use rates, due to potent soil-activity and residual effect.
-
Broad-spectrum action: controls both annual grasses and many broad-leaf weeds.
-
Soil-borne mode means reduced reliance on post-emergence treatments, enabling integrated weed-management systems.
-
High formulation content (480 g/L) offers efficiency in transport/storage for export operations.
Formulation & Specifications
“480 g/L EC” Explained
The “480 g/L EC” designation signifies that the formulation contains approximately 480 g of active ingredient Trifluralin per litre of product, in an Emulsifiable Concentrate (EC) formulation type. This means the product is a liquid concentrate which must be diluted for application, and is designed for soil incorporation or surface treatment prior to weed emergence.
Packaging & Storage
-
Typical packaging sizes: e.g., 20 L, 110 L, 1000 L bulk containers (varies by market).
-
Storage conditions: store in a cool, dry, well-ventilated area, away from ignition sources; keep containers tightly sealed; avoid freezing or direct sunlight.
-
Shelf life: typically 2 years when stored under recommended conditions (check local label).
-
POMAIS supports custom packaging: small-packs (for trial or retail), private-label containers, multilingual labels, tailored MOQ for export markets.
Why This Formulation for Export Markets
For international distributors and brand-builders, the 480 g/L EC offers logistic advantages: high active load reduces volumetric weight, liquid format simplifies custom blending/packaging, and the EC is familiar to many markets’ spray equipment systems. Combined with POMAIS’s global export logistics and brand-custom packaging, it enables flexible market entry.

Efficacy & Application Scenarios
Target Crops
Suitable for use in a broad range of crops including cereals (wheat, barley, oats, triticale), legumes (soybean, peanuts, beans), vegetables (carrots, tomatoes, lettuce, capsicums), sugar crops (sugar beet, sugar cane), cotton, ornamentals and forestry (subject to local registration).
Target Weeds / Weed Spectrum
Controls many annual grass species and broad-leaf weeds at or near field sowing. Note: The product is designed for pre-emergence soil activity rather than post-emergence foliar action; thus, timing and soil incorporation are critical for efficacy.
Application Timing & Conditions
-
Best applied before weed emergence, generally at or just before sowing of the crop to ensure the herbicide resides in the soil seed zone.
-
For optimum effect: incorporate into soil or cover lightly (mechanical or water-seal) within 4–24 hours after application, depending on tillage practice.
-
Application rates vary with crop, soil texture, organic matter and weed pressure – light soils generally require lower rates than heavy soils.
-
Soil conditions influenced by: organic matter, moisture, residue cover and compaction – high residue/low incorporation may reduce performance.
-
Residual control can persist for several weeks under optimal conditions; however heavy rainfall, delayed incorporation or low soil activity may reduce effect.
Application Example Table
| Crop Category | Typical Rate* | Soil Treatment Type | Key Notes |
|---|---|---|---|
| Vegetables (light soil) | 0.8–1.2 L/ha | Soil incorporation before sowing | Ensure residue removal & proper depth |
| Soybean/Peanut | 1.0–1.5 L/ha | Pre-plant or pre-emergence | Good for annual grasses + broad-leafs |
| Cereals (wheat/barley) | 1.2–1.8 L/ha | Before or at sowing, shallow incorporation | Pay attention to stubble cover |
*Rates depend on registration, local label, soil condition, weed spectrum. Always follow the official label.
Usage Instructions & Technical Parameters
Dosage & Spray Parameters
-
Dilute the concentrate according to local label recommendations. Ensure full agitation of spray tank and maintain suspension if necessary.
-
Use clean water, ensure no contamination of equipment. Do not leave mixed spray solution standing for extended periods; apply immediately or within label-specified time.
-
Confirm that application equipment (boom, nozzles) is suitable for low-drift, accurate placement into the seed zone or pre-emergence band.
Compatibility & Tank-Mixing Tips
-
Many markets permit tank-mixing with other soil-applied or residual herbicides; however, always conduct a small compatibility test and follow local label guidance.
-
Do not mix with highly acidic or oxidising solutions unless permitted.
-
Avoid storing mixed tank-mixtures beyond the recommended timeframe.
Operational Precautions
-
Avoid application when soil is water-logged, crusted, or has heavy residue cover without suitable incorporation.
-
Ensure adequate soil moisture post-application to activate the herbicide; dry soils may delay activity.
-
Minimise drift and prevent the spray from moving onto sensitive crops or water bodies; maintain buffer zones.
-
Always wear appropriate personal protective equipment (PPE) as indicated on the label; rinse equipment and containers per defined disposal instructions.
Safety, Environmental & Regulatory Overview
Toxicity Profile
Trifluralin has moderate to low mammalian toxicity when used according to label, but poses higher risk to aquatic life and sediment organisms.
Environmental Fate
-
Low water solubility, low mobility in soil, moderate persistence—under some conditions half-life may be substantial, and volatilisation may cause losses if soil is not incorporated.
-
Some regions restrict or regulate its use due to concerns over persistence and aquatic toxicity.
Regulatory Status & Compliance
POMAIS ensures that this product is manufactured to ISO/SGS standards and can supply COA, MSDS, TDS, and registration-dossier support to customers. Nonetheless each customer must verify local registration status, import permit, maximum residue levels (MRLs) and any specific country-level restrictions.
Resistance Management & Use Limitations
Resistance Risk
As a Group 3 herbicide (WSSA/HRAC classification), repeated sole-use of Trifluralin can lead to development of resistant weed populations.
Best Practices to Delay Resistance
-
Rotate with herbicides of different mode of action or include post-emergence herbicides where feasible.
-
Use recommended rates, apply at the correct timing, and incorporate into a full weed-management program (cultural, mechanical + chemical).
-
Avoid repeated use on the same field year-after-year without variation.
Use Limitations & Crop Rotation Notes
-
Because it is a pre-emergence soil herbicide, it has less effect on established weeds or perennial species; weed escapes may require follow-up treatment.
-
Soil incorporation is critical: in no-till or high-residue systems, performance may decline unless appropriate equipment or technique is used.
-
Some sensitive crops or subsequent rotations may impose restrictions; consult local label for safe crop-rotation intervals.
Competitive Advantages & Product Positioning
Product Strengths
-
