Harpin Protein Plant Immunity Elicitor Storage — Biopesticide Tank Selection

Storing Harpin Protein? Start Here

Harpin protein is a biopesticide that helps boost plant immunity and increase crop yield. It's used as a foliar spray to activate plant defenses against a range of pathogens. When storing harpin protein, it's important to keep it in conditions that maintain its stability and effectiveness. The protein is typically available as a liquid concentrate or wettable powder and should be stored in a way that avoids extreme pH levels, high temperatures, and contact with certain metals.

Can you store it in a poly tank?

Yes, you can store harpin protein in a polyethylene tank. Standard HDPE or XLPE tanks are suitable for mixing and storing the solution at typical concentrations used in agriculture. Just ensure that the tank and fittings are free from materials that could degrade the protein, such as copper or galvanized steel.

Key Issue: Metal Contact

Avoid storing harpin protein in tanks or systems that include copper, brass, or galvanized steel. These metals can cause the protein to degrade, reducing its effectiveness. Stick to compatible materials like polyethylene, polypropylene, and stainless steel to ensure the protein remains active.

The safety that actually matters

• Store in a cool, stable environment to prevent protein denaturation.
• Avoid metal contact, especially with copper and galvanized steel.
• Use compatible gaskets and fittings to maintain integrity.

Common questions

What tank materials are best for harpin protein?

HDPE or XLPE tanks with polypropylene or PVC fittings are ideal.

Can I use metal tanks for storage?

Only use stainless steel; avoid copper, brass, and galvanized steel.

What should I do if the solution contacts metal?

Transfer it to a compatible tank immediately to prevent degradation.
