University of California, Davis, researchers have launched a prototype risk assessment calculator for tomato spotted wilt virus.
But they stressed it is intended for trial purposes and guidance only, according to a recent e-newsletter from the Manteca-based California Tomato Research Institute Inc.
The researchers, all from the plant pathology department, are Bob Gilbertson, Neil McRoberts, Ozgur Batuman and A.J. Campbell.
Users input their information, and the researchers will email back a risk estimation and risk status within 24 hours.
The data also will be used to fine-tune the risk assessment model.
During the growing season, they will refer to the risk categories when they provide updates, typically on a weekly basis.
The risk assessment is based on weather and thrips populations.
Western flower thrips spread tomato spotted wilt virus.
