Titled "Tomato Chlorosis Virus and Tomato Infectious Chlorosis Virus," it is narrated by Bill Wintermantel, an Agricultural Research Service research plant pathologist in Salinas, according to a news release.

The two viral diseases are transmitted by whiteflies and are of importance to both greenhouse and open-field production.

Wintermantel will cover symptoms, scouting and how to improve management and limit infection.

The 24-minute presentation will be available through Aug. 31.

The webinar is part of the Focus on Tomato educational Web series.
