Blueberry Disease Control with Magna-Bon CS 2005

Blueberry Disease Control with Magna-Bon CS 2005

Humidity rises. Disease pressure builds. And blueberry growers are left fighting rust, anthracnose, and algal stem blotch with conventional copper programs that don’t hold.

Effective blueberry disease control with copper requires more than surface protection.

Magna-Bon CS 2005 changes that.

This OMRI-listed, in-solution copper sulfate delivers systemic + contact activity, providing more complete blueberry disease control—even under high pressure.

Why Traditional Copper Fungicides Fall Short in Blueberries

Most copper fungicides for blueberries provide only surface protection—leaving growers exposed when disease pressure intensifies.

When conditions favor disease—especially rust and anthracnose—surface-only protection fails fast, leading to rapid spread, defoliation, and lost fruit quality.

Blueberry disease control requires more than surface coverage—it requires protection that works inside the plant.

A Better Approach: Systemic Copper That Performs

Magna-Bon CS 2005 is not another surface-level copper.

It’s an OMRI-listed, in-solution copper sulfate pentahydrate designed to deliver systemic + contact activity—providing protection both on the plant and within plant tissue.

While traditional copper fungicides sit on the surface, Magna-Bon CS 2005 works inside the plant—helping stop disease before it spreads.

Conventional copper stays on the surface. Magna-Bon CS 2005 works inside the plant—where disease actually starts.

How Magna-Bon CS 2005 Works Inside the Plant

Magna-Bon CS 2005 is engineered to do what traditional copper cannot—deliver protection both on the surface and within plant tissue.

  • Penetrates leaf tissue through stomata openings
  • Moves systemically to target bacteria inside the plant
  • Forms a protective copper barrier on the surface

That means disease is stopped before it spreads—inside the plant, where traditional copper can’t reach.

The result: dual-action protection that holds under pressure—inside and out. That’s the difference between managing disease—and actually controlling it.

Why Blueberry Growers Are Making the Switch

✔ Stronger blueberry disease control under high pressure
✔ Proven performance against copper-resistant strains
✔ Effective disease control in blueberries
✔ Ultra-low metallic copper rates (less than ⅛ to ¼ lb/A)
✔ Cleaner applications with reduced environmental impact
