Funding Program: IPM Partnership Grants
Project Title: Development and Dissemination of an Integrated Management Plan for Bacterial Canker of Tomato
Project Directors (PDs):
Christian A. Wyenandt [1]
Kristian Holmstrom [2]
Joseph Ingerson-Mahar [3]
Lead State: NJ

Lead Organization: Rutgers University
Undesignated Funding: $39,942
Start Date: Apr-01-2006

End Date: Mar-31-2007
Pests Involved: bacterial canker
Site/Commodity: tomatoes
Area of Emphasis: seeds
Summary: This project was undertaken to address the growing occurrence and severity of bacterial canker of tomatoes in New Jersey. Nine commercial growers in Hunterdon, Morris and Warren in northern New Jersey counties were asked to participate in this study based on their involvement in the Rutgers Cooperative Extension Integrated Pest Management (IPM) Program and their history of bacterial canker on tomato. Participants were provided information regarding practices that would help prevent the development and spread of bacterial canker. Additionally, participants were strongly advised to heat treat all tomato seeds prior to sowing to eliminate bacterial pathogens that might be present. Heat treatment of seed was a new practice for NJ growers. Heat treatment facilities were provided by the RCE IPM Program and one of the project participants.

Growers were asked to follow as many of the practices as were possible. They were surveyed at the end of each season to determine what varieties they grew, which practices they were able to complete and what their overall impressions were of the progress (or lack of) as a result of the project. The occurrence, severity and characteristics of bacterial canker infections (if present) were documented on each farm. The primary goal of these activities was to examine the tomato production activities on all farms and attempt to use the information to determine where weaknesses that contributed to bacterial canker infections occurred. All developments were reported at local, state and regional grower meetings; commodity working group meetings, and industry advisory meetings. A document entitled: Bacterial Canker of Tomato: Background and Management Strategies was produced and will be distributed at grower meetings.


Objectives: 1. Identify grower practices that contribute to poor control of bacterial canker.

2. Demonstrate the importance of incorporating seed heat-treatment into an integrated management plan for bacterial canker.

3. Demonstrate the importance of integrated tactics, including seed heat-treatment, vigorous sampling, and hygienic production practices in a management plan for control of bacterial canker.

4. Promote an integrated plan for managing bacterial diseases of tomato.
