Glyphosate Chemical Compatibility
Storing Glyphosate? Start Here
Glyphosate is a widely used herbicide, essential for farmers, industrial weed control, and even home gardeners. It's known for its role in managing weeds in crops like corn, soybeans, and cotton, as well as maintaining clear utility rights-of-way and railroads. When storing glyphosate, it's crucial to understand the best practices to ensure safety and effectiveness.
Can you store it in a poly tank?
Yes, glyphosate is compatible with most common storage materials, including HDPE, XLPE, and polypropylene. These materials are standard for farmer-nurse tanks and bulk storage at co-ops and ag-retail sites. Avoid using galvanized steel, as it can corrode over time due to the surfactants in glyphosate formulations.
Watch out for galvanized steel
While glyphosate is generally stable and easy to store, it can cause slow corrosion in galvanized steel tanks due to the surfactants. This can lead to zinc runoff, which poses environmental risks. Opt for epoxy-coated steel or direct HDPE/XLPE tanks for long-term storage.
The safety that actually matters
- Always use proper spill containment to prevent environmental contamination.
- Ensure tanks are grounded and secured to prevent accidents.
- Regularly inspect tanks for any signs of wear or leaks.
- Follow EPA FIFRA guidelines for storage and handling.
Common questions
- Can glyphosate be stored outside?
- Yes, but ensure tanks are protected from extreme weather and have spill containment measures in place.
- What should I do if my tank shows signs of corrosion?
- Switch to a more suitable material like HDPE or XLPE, and consult with a professional for proper disposal of the corroded tank.
- Is it safe to store glyphosate near other chemicals?
- Yes, but keep it segregated from incompatible substances and follow all safety guidelines for chemical storage.
