Trifluralin Dinitroaniline Preemergence Tank Selection

Storing Trifluralin? Start Here

Trifluralin is a widely used herbicide, especially in cotton, soybean, and other row-crop production. It helps control a variety of weeds and is typically applied to soil before planting. If you're involved in agriculture, especially in the cotton or soybean belts, you're likely familiar with its benefits. When it comes to storing trifluralin, it's important to know the best practices to ensure safety and effectiveness.

Can you store it in a poly tank?

Yes, you can store trifluralin in a polyethylene (poly) tank. High-density polyethylene (HDPE) tanks are commonly used for this purpose. They are effective for atmospheric storage of trifluralin formulations. However, be aware that trifluralin can cause orange staining over time, which is mainly cosmetic.

Watch out for staining

Trifluralin is known for its bright-orange color, which can stain surfaces it comes into contact with. While this staining is generally cosmetic, it can be unsightly. Ensure tanks are opaque and UV-stabilized to minimize photodegradation and maintain the integrity of the herbicide.

The safety that actually matters

• Use UV-stabilized and opaque tanks to prevent photodegradation.
• Ensure proper gasket materials like Viton or PTFE to avoid chemical reactions.
• Regularly inspect tanks for any signs of wear or damage.

Common questions

What type of tank is best for storing trifluralin?

HDPE tanks are standard for storing trifluralin due to their resistance to the chemical and ability to handle the aromatic solvents in the formulation.

Do I need special gaskets for trifluralin storage?

Yes, use Viton or PTFE gaskets as they are compatible with trifluralin and its solvents.

Is the orange staining a problem?

The staining is mostly cosmetic and does not affect the function of the tank, but it can be minimized by using UV-stabilized tanks.
