Research Project: Development of a virus IPM strategy for processing tomatoes

Location: Crop Improvement and Protection Research

Project Number: 5305-22000-013-02
Project Type: Trust

Start Date: Jan 01, 2010
End Date: Sep 30, 2013

Objective:
The project addresses the dynamics of annual virus infections of tomato by identifying and differentiating important reservoir hosts of tomato viruses that facilitate transmission to the crop from those that are poor sources for transmission, identifying key viruses in new areas of processing tomato production, and monitoring vector incidence (sticky cards) in correlation with virus incidence. The overall goal is to develop targeted IPM strategies to minimize impact of viruses on tomato production based on knowledge of epidemiology including important reservoir hosts and vectors by region.

Approach:
Monitor transmission of Beet mild curly top virus and Beet severecurly top virus from tomato and alternate crop and weed hosts in relation to virus concentration in the host plant; Determine population dynamics of vectors using standard methodologies; These laboratory/greenhouse level studies will determine the significance of crop and weed hosts long thought to be reservoirs, and determine their importance or lack of importance epidemiologically using modern technology.
