Dr. Jim Adaskaveg Research Confirms Superior Walnut Blight Control with Magna Bon CS 2005 and Manzate DF
Walnut growers confront one of their most persistent seasonal threats: walnut blight. Under cool wet spring conditions the disease can spread quickly during bloom and early shoot development damaging buds reducing nut set and significantly impacting yield and quality. Once infection begins control becomes far more difficult making proactive management essential.
In replicated field trials conducted by Dr. Jim Adaskaveg at the University of California Riverside, Magna-Bon CS 2005 delivered exceptional performance under high disease pressure. When combined with Manzate DF, CS 2005 achieved 100 percent control of walnut blight. Even as a standalone treatment, CS 2005 provided 94 percent control, outperforming conventional copper programs that often struggle against resistant strains. These results reinforce why walnut blight control CS 2005 strategies are gaining attention among progressive growers.
Magna-Bon CS 2005 utilizes advanced in-solution copper sulfate pentahydrate technology engineered for enhanced plant uptake and superior coverage at lower metallic copper rates. The result is consistent, research proven protection that safeguards bloom, preserves nut set, and strengthens overall walnut blight control.
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.
