      AgriPhage applied as a preventative foliar spray significantly reduced severity of bacterial canker of greenhouse tomato in two of three years. Area under the disease progress curves (AUDPC) indicated that AgriPhage slowed the progression of bacterial canker symptom development by 50% and 59% in 2006 and 2007, respectively. Plant mortality was significantly reduced by 76% in 2006 as compared to the inoculated control. AgriPhage-treated plants produced significantly greater total yield in 2006 only. Copper and Kasumin sprays also significantly reduced severity (AUDPC) of bacterial canker in 2007 as compared to the inoculated control. However, none of these treatments reduced symptom development or increased yield in 2008.
