California Industry on High Alert

摘要

The discovery of the deadly tomato yellow leaf curl virus (TYLCV) earlier this spring in California has the tomato industry on high alert. "TYLCV is recognized as the worst, most pathogenic tomato virus there is," says Robert Gilbertson, a plant pathologist at the University of California, Davis. Diseased plants were found in a Brawley greenhouse, near the California/Mexican border. Experts believe that the virus could have been brought in via tomato transplants from Mexico or Texas, or that it could have been carried in by whiteflies.
