Paraquat Dichloride Storage — RUP Tank Selection (Gramoxone Burndown)

Storing Paraquat Dichloride? Start Here

Paraquat dichloride is a powerful herbicide used for vegetation control, but it comes with strict handling rules. Only certified applicators can mix, load, and apply it. If you're storing paraquat, you need to ensure that your tank setup meets all safety and regulatory standards. This includes using tanks that are compatible with paraquat's chemical properties and keeping the storage area free from materials that could react negatively with it.

Can you store it in a poly tank?

Yes, you can store paraquat dichloride in polyethylene tanks. Both HDPE and XLPE tanks are suitable for this purpose, offering durable and safe storage options. Make sure to use carbon-black-stabilized resin for outdoor tanks to protect against UV damage.

Watch Out for Clay Contamination

One critical issue with paraquat is its strong affinity for clay. Never store paraquat in areas where it can come into contact with bare clay soil, as it will bind to the clay and cause permanent contamination. Always use concrete or HDPE-lined containment systems to avoid this problem.

The safety that actually matters

• Only certified applicators can handle paraquat.
• Use closed-transfer systems for loading and mixing.
• Store on concrete or HDPE-lined surfaces, not bare soil.
• Ensure proper ventilation to manage fumes.
