Triclopyr Pyridine Forestry/ROW Tank Selection

Storing Triclopyr? Start Here

Triclopyr is a widely used herbicide for managing vegetation in forestry, utility, and right-of-way areas. It's effective for controlling broadleaf and woody plants, making it a staple for operations in forestry site preparation, utility and railroad corridors, and rangeland brush control. Depending on the formulation, triclopyr can be stored in different types of tanks, but it's important to choose the right one to ensure safety and effectiveness.

Can you store it in a poly tank?

Yes, triclopyr can be stored in a polyethylene (poly) tank. The aqueous triethylamine salt formulation (like Garlon 3A) is compatible with HDPE tanks. The oil-soluble butoxyethyl ester formulation (such as Garlon 4 Ultra) can also be stored in HDPE tanks, but requires specific elastomers like Viton or PTFE for plumbing due to its petroleum solvent carrier.

Key Issue: Elastomer Compatibility

When storing the oil-soluble ester formulation of triclopyr, it's crucial to use the right elastomers. Viton or PTFE gaskets are necessary because the petroleum solvent can degrade other materials like EPDM or buna-N. This ensures the integrity of your storage system and prevents leaks or failures.

The safety that actually matters

• Ensure tanks are UV-stabilized if stored outdoors to prevent degradation.
• Use appropriate elastomers to prevent chemical reactions and leaks.
• Follow all local regulations for herbicide storage and handling.

Common questions

Can triclopyr be stored in a metal tank?

Yes, stainless steel is compatible with both formulations of triclopyr.

What is the maximum storage capacity for triclopyr in poly tanks?

For the aqueous formulation, tanks can range from 500 to 6,000 gallons. For the ester formulation, the range is 500 to 3,000 gallons.

Do I need to worry about off-gassing with triclopyr?

No significant off-gassing is associated with triclopyr when stored properly in compatible tanks.
