The Perfect Match for Combating Fire Blight!
Maximize Orchard Protection with Magna-Bon CS 2005 & Regalia®
When it comes to managing Fire Blight—one of the most devastating diseases in apples and pears—timing, tools, and trusted partnerships make all the difference. As bloom season approaches, pome fruit growers are preparing their first lines of defense. That’s where The Perfect Match for Combating Fire Blight comes in — the proven combination of Magna-Bon CS 2005 paired with ProFarm Regalia® biofungicide, delivering exceptional protection and performance when it matters most.
Why Growers Are Making the Switch
Recent Cornell University research in Geneva, NY, showed remarkable control of Fire Blight when growers applied Magna-Bon CS 2005 and Regalia together. In a heavily infected ‘Idared’ orchard (90% infection rate), five applications from 20% bloom through terminal shoot growth achieved 92% control using 1 pt of CS 2005 + 32 oz of Regalia.
In a second trial (9.25% infection), the same program achieved 100% control—proving that this duo outperforms traditional copper programs while using significantly less metallic copper.
🌿 OMRI-Listed Copper Solution – CS 2005 is a copper sulfate pentahydrate in-solution formula that’s safe for organic and conventional systems.
💧 Systemic, Long-Lasting Protection – Moves within the plant to strengthen natural defenses.
⚡ Low Metal Load, High Efficacy – Delivers strong disease suppression with less than 1/8 lb of metallic copper per acre.
🌸 Flexible Use Window – Effective from silver tip through terminal shoot growth, covering critical infection periods.
🌎 Sustainable Choice – Supports long-term orchard health and soil balance.
