Research Team Looks at Plant Activators

摘要

The three most common bacterial diseases of tomato in New York are bacterial speck, caused by Pseudomonas syringae pv. tomato, bacterial spot, caused by Xanthomonas campestris pv. Vesicatoria, and bacterial canker, caused by Clavibacter michiganensissubsp. michi-ganensis. While copper is effective, particularly against bacterial speck and spot, we have studied the efficacy of several alternative compounds available for control of bacterial pathogens. Specifically, we have tested plant activators over three growing seasons as potential control strategies for bacterial speck of tomato and compared them to standard copper-based control strategies.
