Bacterial Disease Management Current Efficacy Research
IR-4 Bacterial Efficacy Project • Started in 2006 and continuing through 2011 • Foliar and/or drench applications examined • Bacteria
– Erwinia chrysanthemi – Pseudomonas cichorii, P. marginalis, P. syringae, Pseudomonas spp. – Xanthomonas campestris and Xanthomonas spp.
• Researchers – Dr. Chris Becker, BAAR Scientific LLC – Dr. Ann Chase, Chase Horticultural Research – Dr. Dave Norman, University of Florida – Dr. Jay Pscheidt, Oregon State University – Dr. M.S. Reddy, Auburn University – Mr. Rich Regan, Oregon State University – Dr. Jim Strandberg, University of Florida
– These researchers also donated non-IR-4 data for this presentation and

Conversion to Percent Efficacy
Relative impact based on scale between inoculated and uninoculated ratings (Inoculated – Treatment) Percent Efficacy = ----------------------------------------- *100% (Inoculated – Uninoculated) This is one way to be able to compare efficacy across different experiments with different data collected

Conclusions
Copper-based products tended to provide good efficacy
Acibenzolar provided the best efficacy for Xanthomonas followed closely by Aliette; Citrex may provide efficacy
CuPro provided the best efficacy for Erwinia
Acibenzolar and CuPro provided the best efficacy for Pseudomonas
