Information Available for Growers on a New Disease in California Tomatoes

摘要

In March 2007, the virus that causes tomato yellow leaf curl popped up in greenhouse tomatoes being grown by a high school science class in Imperial County. Because this disease is new to California and potentially devastating for tomato production, agencies have produced an informational brochure to help curtail its spread. Tomato yellow leaf curl virus is a member of a family of viruses that are spread by whiteflies or leafhoppers. The virus infects peppers, some tobacco species, and a range of weed species, but tomato is by far the most important host.
