Trifluralin 480g/L EC | Selective Pre-Emergent Herbicide for Broadleaf and Grass Weed Control

Mode of Action

Trifluralin works by disrupting mitosis in weed seedlings, stopping them before they emerge.

• Selectivity: Trifluralin is absorbed mainly by weed roots and shoots before emergence, without harming established crops.

• Soil Activity: The product must be incorporated into the soil soon after application to activate its residual properties.

Trifluralin is a dinitroaniline-class herbicide that acts by inhibiting cell division in susceptible weeds. It interferes with microtubule formation during mitosis, which prevents weed seedlings from forming normal root and shoot systems. Since it is absorbed primarily through the roots and shoots of germinating seeds, Trifluralin remains inactive against established weeds and safe for most planted crops when used correctly.

Incorporating the herbicide into the topsoil shortly after application is essential to activate its mode of action. This ensures that the active ingredient stays in the root zone, where it can effectively target emerging weed seeds.

Trifluralin acts by inhibiting cell division in the roots and shoots of germinating weed seeds. It disrupts microtubule formation during mitosis, preventing proper growth and establishment of weeds.

Application Crops and Target Weeds

Suitable across multiple crop systems and highly effective on common early-season weeds.

Trifluralin 480g/L EC is registered for broad agricultural use and flexible enough to serve both food and industrial cropping systems. Key crop categories include:

• Row Crops: Peanuts, Soybeans, Cotton, Sunflowers

• Vegetables & Ornamentals: Onions, Beans, Tomatoes, Nursery Plants

• Non-Cultivated Areas: Orchards, Vineyards, Railroads, Non-arable zones, Reservoir perimeters

Target Weeds include annual broadleaf and grassy weeds like:

• Barnyardgrass (Echinochloa spp.)

• Pigweed (Amaranthus spp.)

• Foxtails (Setaria spp.)

• Crabgrass (Digitaria spp.)

• Lambsquarters (Chenopodium album)

These weeds typically emerge at the same time or just before crops. Early elimination through pre-emergent application ensures the crops grow with less competition for water, light, and nutrients.

Recommended Application Rates

Precise pre-plant application and mechanical incorporation are key to optimal efficacy.

Trifluralin must be applied prior to weed and crop emergence, followed immediately by soil incorporation using appropriate tools like rotary tillers or disc harrows.

The following dosage guidelines are based on field trials and agronomic best practices:

• Application Timing: Pre-plant soil incorporation

• Incorporation Depth: 5–10 cm using mechanical tillage

• Water Volume: 200–400 L/ha depending on equipment and soil type

Product Advantages

A well-established, cost-effective, and highly adaptable weed management tool.

• Broad-spectrum control: Effective on a wide range of early-season weeds

• Residual activity: Prevents weed emergence for several weeks after application

• Excellent crop compatibility: Safe when applied according to label instructions

• Low volatility: Reduced risk of off-target movement

• Cost-effective: Competitive price with long-standing market presence

Trifluralin 480g/L EC offers long-term benefits that make it a staple in weed control programs worldwide. Its residual control ensures weed suppression for 4 to 6 weeks, drastically reducing early-season competition and labor costs associated with multiple herbicide applications. This prolonged activity allows crops to grow in weed-free conditions during their most critical development stages.

It’s compatible with a wide range of crops, including both food and industrial crops, and integrates seamlessly into Integrated Pest Management (IPM) programs. This compatibility provides distributors and farmers with flexibility in planning seasonal rotations and crop protection strategies.

By eliminating weed pressure early, Trifluralin ensures stronger seedling establishment and contributes to higher yields. Furthermore, its low volatility and soil stability make it less prone to drift or rapid degradation, enhancing its field performance across variable environmental conditions.

Finally, Trifluralin is a proven chemistry, trusted for decades across global markets. Its consistent field performance and broad registration footprint give both growers and distributors confidence in reliability and value.

Trifluralin 480g/L EC is valued by distributors and growers for its proven efficacy and flexible fit in weed control programs.

Toxicological and Environmental Profile

Moderate toxicity requires safe handling, but minimal long-term residue risk when used properly.

• WHO Toxicity Classification: Class III (slightly hazardous)

• Aquatic Toxicity: Avoid contamination of water bodies

• Non-target Effects: Minimal impact when properly incorporated; not suitable for areas with shallow water tables or sensitive aquatic environments

• PPE Requirements: Gloves, goggles, protective clothing

While Trifluralin is only slightly hazardous under WHO toxicity classification, it still requires proper safety protocols. Applicators should always wear personal protective equipment (PPE) including gloves, goggles, long sleeves, and masks to prevent skin or eye exposure during mixing and spraying operations.

Its ecotoxicity profile necessitates care around aquatic environments—avoid runoff into streams or irrigation ditches and refrain from using in zones with high groundwater exposure. However, when incorporated into the soil as directed, Trifluralin shows minimal environmental mobility, breaking down naturally over time and posing little long-term risk.

These characteristics make it a reliable choice when applied responsibly, especially in dryland or well-managed irrigated systems.

Trifluralin is moderately toxic and should be handled with standard agricultural precautions.

Storage and Transportation

Stable in storage under proper conditions, with straightforward logistics.

• Shelf Life: 2 years in original, sealed containers

• Storage Conditions: Cool, dry, well-ventilated place away from food/feed

• Transport Classification: Non-hazardous under most international regulations

Trifluralin 480g/L EC is a chemically stable product when stored in its original, sealed containers. It maintains efficacy for up to 2 years under cool, dry, and ventilated storage conditions. Containers must be kept out of direct sunlight and separated from any food, water, or animal feed items.

For distributors and logistics teams, Trifluralin is classified as non-hazardous under most global shipping frameworks, which simplifies cross-border export and import procedures. However, standard precautions should still be taken during transport, ensuring proper labeling and separation from incompatible goods.

Ensure correct handling to maintain product integrity and safety.

Frequently Asked Questions (FAQs)

Q1: Can Trifluralin be used post-emergence?
A1: No, it must be applied before weed or crop emergence. It has no curative effect and will not affect established weeds.

Q2: Is it suitable for fruit orchards?
A2: Yes, when used as a soil-incorporated pre-emergent treatment under the tree canopy. Avoid foliar contact with tree leaves.

Q3: What application tools are recommended?
A3: Use ground boom sprayers for even coverage followed by mechanical incorporators such as disc harrows or rotavators to mix the product into the topsoil.

Q4: Can Trifluralin be mixed with fertilizers?
A4: Yes, in many cases Trifluralin can be tank-mixed with compatible fertilizers or micronutrients, but a jar test is always advised to confirm physical and chemical compatibility.
