Malathion Storage — Organophosphate Insecticide Tank Selection (Fyfanon, ULV)

Storing Malathion? Start Here

Malathion is a widely used organophosphate insecticide, especially in agriculture and public health for mosquito control and fruit fly eradication. It's known for its relatively lower toxicity to mammals compared to other organophosphates. Whether you're managing a farm, a public health program, or a pest control operation, storing malathion properly is crucial for safety and effectiveness.

Can you store it in a poly tank?

Yes, but with considerations. High-density polyethylene (HDPE) tanks are suitable for malathion storage, particularly for emulsifiable concentrates (EC). However, be cautious with aromatic solvents in the EC, as they can permeate over time. For ultra-low-volume (ULV) concentrates, premium materials like PVDF or PTFE are recommended.

Aromatic Solvent Concerns

The aromatic solvents in malathion EC can attack certain plastics and elastomers. Over time, these solvents may permeate through standard poly tanks, so dedicated tanks with appropriate gaskets, like Viton, are advised to prevent degradation and ensure safety.

The safety that actually matters

• Use dedicated tanks for malathion to prevent contamination.
• Ensure tanks are UV-stabilized if stored outdoors.
• Match gaskets to the manufacturer chart for chemical compatibility.
• Regularly inspect tanks for signs of solvent permeation or wear.

Common questions

Can I use a standard HDPE tank for malathion?

Yes, but ensure it's dedicated to malathion to prevent solvent uptake.

What gasket material should I use?

Viton is recommended for malathion, especially for ULV concentrates.

Do I need to worry about UV exposure?

Yes, if storing outdoors, ensure your tank is UV-stabilized.
