Chlorothalonil Storage — Broad-Spectrum Fungicide Tank Selection

Storing Chlorothalonil? Start Here

Chlorothalonil is a widely used fungicide for crops like vegetables, peanuts, and potatoes, as well as turf and ornamentals. It's been a staple in agriculture since 1966 due to its effectiveness against a variety of plant diseases. If you're storing this chemical, understanding the right tank setup is crucial for safety and effectiveness.

Can you store it in a poly tank?

Yes, chlorothalonil flowable concentrate can be stored in polyethylene tanks. High-density polyethylene (HDPE) and cross-linked polyethylene (XLPE) tanks are both suitable, especially when stabilized with carbon black for outdoor durability. Ensure the tank is equipped with EPDM gaskets for optimal chemical resistance.

Key Issue: Alkaline Degradation

While chlorothalonil is stable in neutral conditions, it can degrade in alkaline solutions. If you're mixing it with high-alkalinity water or fertilizers, keep an eye on the pH to maintain its effectiveness.

The safety that actually matters

• Use tanks with proper UV stabilization for outdoor storage.
• Ensure gaskets and fittings are compatible with chlorothalonil.
• Monitor pH levels when mixing to prevent degradation.
• Follow all safety guidelines for handling and application.

Common questions

What tank size is recommended?

Standard sizes range from 1,500 to 15,000 gallons, depending on your storage needs.

Can I use other gasket materials?

EPDM is preferred, but Viton can be used if handling multiple chemicals.

Is chlorothalonil safe for all crops?

It's widely used on many crops, but always check the specific crop label and guidelines.
