Research: Evaluation of New Bactericides for Management of Olive Knot After Inoculation with Psv – Field Studies
Research Trial Results — 100% Control of Olive Knot
In an updated research trial led by Dr. Jim Adaskaveg, a tank mix of 27 ounces of Magna-Bon CS 2005 combined with 16 ounces of Champ (per 100 gallons water) achieved 100% control of olive knot disease under research trial conditions.
With a 37% control, clearly demonstrating the superior performance of the CS 2005 + Champ combination against Pseudomonas savastanoi, the causal agent of olive knot.
For growers battling olive knot, this translates to fewer infections, higher yields, and less disease pressure season after season.

Why Growers Should Use Magna-Bon CS 2005 for Olive Knot
1. Proven Research-Backed Performance
In the latest trial led by Dr. Adaskaveg, the CS 2005 + Champ combination achieved 100% control of olive knot, showing how effective CS 2005 is at suppressing Pseudomonas savastanoi. This performance gives growers a reliable, research-proven option for managing olive knot under real-world conditions.
2. OMRI-Listed for Organic Production
Magna-Bon CS 2005 is OMRI-listed, offering growers an organic-compliant copper option with exceptional disease control performance. This makes it a powerful fit for both organic and conventional programs focused on sustainability and compliance.
3. Systemic Activity and Superior Coverage
As a copper sulfate pentahydrate, in-solution formula, Magna-Bon CS 2005 delivers superior coverage and better uptake than conventional copper products. Its systemic capabilities provide internal plant protection, strengthening defenses where it matters most.
4. Environmentally Responsible and Highly Efficient
Because CS 2005 is more efficient, you can use less total metallic copper per acre while achieving better disease control. That helps reduce environmental load and slows the development of pathogen resistance — without sacrificing performance or crop safety.
5. Compatible and Flexible in the Tank
CS 2005 performs exceptionally well when tank-mixed with partners like Champ, offering excellent compatibility and enhanced control across multiple bacterial and fungal diseases.
6. Broad-Spectrum Protection
Beyond olive knot, Magna-Bon CS 2005 helps manage other bacterial and fungal diseases — including fire blight, bacterial spot, and anthracnose — making it a cornerstone product for integrated, season-long protection.
Protect Your Orchard — The Proven Way
Recent research led by Dr. Jim Adaskaveg reinforces that Magna-Bon CS 2005 delivers reliable, field-proven control against one of the most persistent and damaging olive diseases — Olive Knot.
By integrating Magna-Bon CS 2005 into your spray program, growers can prevent infection following pruning, wounding, or periods of high disease pressure, safeguarding orchard health and maximizing yield potential.
For best results, maintain proper timing, thorough coverage, and strict adherence to label directions. Always consult your local crop advisor or Magna-Bon for region-specific guidance.
