Tomato Yellow Leaf Curl Virus Found in Riverside County, but Still Not Widespread in California

摘要

The good news about the tomato yellow leaf curl virus—the world's worst tomato disease—is that it hasn't spread to the San Joaquin Valley or any other major tomato growing areas in California. The bad news is that the disease seems to have established itself in Imperial County and, for the first time has spread north to Riverside County. So far, the Riverside findings have only been in backyard gardens, says Robert Gilbertson, a plant pathologist at the University of California, Davis, In light ofall the efforts of the industry these past two years to prevent the movement of contaminated material, it's likely that the homeowner got the infected plant from a big box store, Gilbertson says.
