Trifluralin Herbicide
Trifluralin is a powerful herbicide used primarily for pre-emergence weed control in a variety of crops. It works by targeting the roots and shoots of germinating weeds, effectively preventing them from growing. This guide will explore Trifluralin's applications, its optimal usage rates, and safety considerations to ensure you get the best results in your farming operations.
What is Trifluralin?
Trifluralin is a selective herbicide that is part of the dinitroaniline chemical group. It's widely used to control grass and broadleaf weeds in drilled crops, inter-row crops, and transplanted crops. Trifluralin works by inhibiting root cell division in weeds, thus preventing seedling establishment. It’s most effective when applied to the soil before weed seeds begin to germinate.
Trifluralin Herbicide: Active Ingredient and Formulation
Trifluralin is typically formulated in a liquid form that can be mixed with water for application. It is applied directly to the soil, where it is incorporated to ensure even distribution and to maximize its effectiveness in controlling weeds. It is especially effective in sandy soils and loamy soils, offering a solution for farmers looking to manage weed problems pre-planting or in early crop stages.
How Trifluralin Works
Trifluralin prevents the germination and growth of weeds by disrupting cell division in the root system. When applied to the soil, it forms a barrier that prevents the sprouting of weeds. This barrier remains active in the soil for a period of time, depending on soil conditions and weather, providing effective long-term weed control.
Trifluralin Application Rates for Various Crops
Here’s a detailed breakdown of the application rates and timing for Trifluralin depending on the crop and soil type:
1. Drilled Crops:
| Crops | Up to 4% Organic Matter (Sandy or Light Soils) | 5-8% Organic Matter (Clay, Silt or Loam Soils) | Application Timing |
|---|---|---|---|
| Carrots, Parsnips, Celery, Kale, Swedes, Sunflower, Beans | 1.7 L/ha | 2.5 L/ha | Apply immediately before or up to 6 weeks prior to sowing. |
| Barley | 1.25–1.7 L/ha | 1.7 L/ha | Apply 14 days prior to sowing. May sow immediately after incorporation if conditions are favorable. |
| French Beans, Linseed, Lucerne, Oilseed Rape | 1.25–1.7 L/ha | 1.7–2.1 L/ha | Apply immediately before planting. At least 14 days pre-planting under cold, wet conditions. |
| Peas (Field & Process) | 1.25–1.7 L/ha | 1.7–2.5 L/ha | Apply 1–2 weeks before sowing. |
2. Inter-row Established Crops:
| Crops | Up to 4% Organic Matter (Sandy or Light Soils) | 5-8% Organic Matter (Clay, Silt or Loam Soils) | Application Timing |
|---|---|---|---|
| Pumpkins, Squash, Melons, Cucumbers | 1.7 L/ha | 2.5 L/ha | Apply post-emergence. Incorporate inter-row. |
3. Transplant Crops:
| Crops | Up to 4% Organic Matter (Sandy or Light Soils) | 5-8% Organic Matter (Clay, Silt or Loam Soils) | Application Timing |
|---|---|---|---|
| Cabbage, Cauliflower, Brussels Sprouts, Broccoli, Tomatoes, Peppers | 1.7 L/ha | 2.5 L/ha | Apply immediately before or up to 6 weeks prior to transplanting. |
Best Practices for Application
1. Soil Conditions:
- Ensure the soil is flat, free from debris, and not excessively wet.
- Foreign materials such as plant residues or stones can reduce Trifluralin’s effectiveness.
2. Mixing Instructions:
- Partially fill the spray tank and add the required amount of Trifluralin herbicide.
- Agitate the solution thoroughly while filling the tank and during spraying. Re-agitate the solution if there’s a break in spraying.
3. Incorporation:
- Trifluralin must be incorporated into the soil thoroughly to prevent crop damage and achieve optimal weed control.
- Use power-driven rotary implements set to cut to a depth of 5-10 cm.
- Two separate cultivations in different directions (90° to each other) are recommended for better incorporation.
Safety and Handling of Trifluralin Herbicide
Precautionary Measures:
- Hazard: Trifluralin is harmful if swallowed and can cause mild skin and eye irritation. It may also cause an allergic skin reaction and is highly toxic to aquatic life with long-lasting effects.
Personal Protective Equipment (PPE):
- Wear protective clothing, including gloves, face shield, and appropriate footwear when handling the herbicide.
- Avoid inhaling mist or vapors. Wash exposed skin thoroughly after handling.
Storage & Disposal:
- Store in a cool, dry place, out of reach of children.
- Dispose of empty containers and unused product according to local environmental regulations.
Environmental Impact and Safety
While Trifluralin is highly effective at controlling weeds, it is also toxic to aquatic environments. Careful application and proper handling are essential to minimize its impact on non-target organisms and the surrounding environment. Make sure to follow local regulations regarding herbicide use and to avoid spraying during rain or when runoff is likely.

Frequently Asked Questions (FAQs)
1. How does Trifluralin prevent weeds?
Trifluralin inhibits root cell division in weeds, preventing them from establishing and growing. It creates a barrier in the soil that stops weed seeds from sprouting.
2. What crops can benefit from Trifluralin application?
Trifluralin is ideal for crops like carrots, peas, barley, and various vegetables, especially those planted in sandy or loamy soils.
3. Can Trifluralin be used in organic farming?
Trifluralin is not typically used in organic farming due to its chemical nature. Always check organic certification standards for permissible herbicides.
4. What is the best time to apply Trifluralin?
Trifluralin should be applied either immediately before sowing or up to 6 weeks before sowing/transplanting for best results.
