New Cornell computer model to help grape growers adapt to shorter winters

As the climate changes, winter is shortening, causing vines and trees to bud earlier in the year and increasing the chances they will be exposed to spring cold snaps and frost that can be hazardous to yields.

A new Cornell-developed computer model that estimates the temperatures that cause freeze damage in a dozen grape cultivars can either ease growers’ worries that no damage was likely done or help them to plan for the season when damage does occur.

The model, which is publicly available, has a web interface that allows Northeast users to select a weather station nearest to them from several thousand and choose from 12 grape cultivars to get a prediction within a couple of degrees of accuracy on whether their vines and especially the buds may have experienced freeze damage. |READ MORE
