Research-Proven Walnut Blight Control – Magna-Bon CS 2005 + Manzate® DF
Walnut growers face one of their toughest challenges: copper-resistant walnut blight can devastate yields if left unchecked. In research trials at the University of California-Riverside, Magna-Bon CS 2005 combined with Manzate® DF delivered 100% control of walnut blight, even under high infection pressure. CS 2005 alone achieved 94% control, outperforming traditional copper products.
🔬 How the Program Works
-
Trial Design: Led by Dr. Jim Adaskaveg, walnut trees were inoculated with copper-resistant strains and treated with four sprays between April and May. (4/6, 4/14, 4/23, 5/1)
-
Application Rates: 27 oz of Magna-Bon CS 2005 + 2.4 lb of Manzate® DF per application.
-
Result: 100% control under trial conditions.
Why This Combination Works
-
Targeted copper formulation: Magna-Bon CS 2005 is an OMRI-listed copper sulfate pentahydrate in-solution formula delivering effective disease suppression with lower copper active ingredient compared to many traditional coppers.
-
Synergy with Manzate: Adding Manzate (mancozeb) enhances efficacy, improving disease control even against copper-resistant strains.
-
Reduced environmental impact: The lower copper A.I. in CS 2005 helps growers manage resistance and cumulative copper loads while maintaining control performance.
Additional research shows Magna-Bon CS 2005 alone achieved 94% control, even with infection pressure above 34%, while some conventional copper hydroxides performed worse than untreated controls. These results underline the product’s superior efficacy and consistency.
