Predicting grapevine cold hardiness

  • June 1st, 2011

Being able to predict the cold hardiness of grapes could help growers know how to respond when severe freezes occur.

Researchers at Washington State University are developing a computer model for predicting grapevine cold hardiness that could be in place next winter. The model, currently being integrated with WSU’s AgWeatherNet, [...]
