The Potential of Light Treatments to Suppress Certain Plant Pathogens and Pests 

Plant Pathologist David Gadoury's collaborative research shows  nighttime applications of UV light can control powdery mildew on grapes, strawberries, and in greenhouses. 


Five Questions for David Gadoury

David Gadoury is a a senior research associate at Cornell AgriTech, whose research encompasses such cutting edge subjects as high-thoroughput phenotyping of powdery mildew and pest management using UV light treatments.

How Grapevine Roots Grow

The roots of the grape may be difficult to see, but they are equally as important as the above ground grapevine for management and vine health. Extension specialist Tim Martinson explains root biology and seasonal growth patterns. 


Crop load spatial distribution visual depictionConsiderations on Spatial Crop Load Mapping

James Taylor, of the Efficient Vineyard Program, discussing how cost- and time-effective methods to  spatially map crop load  across the vineyard could provide a decision support system to help managers apply the best shoot and crop thinning practices.

Deconstructing cold hardiness: variation in supercooling ability and chilling requirements in the wild grapevine Vitis riparia

Jason Londo, Geneva-based USDA-ARS scientist, examined 43 Vitis riparia accessions to examine cold-hardiness traits that decrease the likelihood of winter injury, including low mid-winter bud freezing temperatures, high chilling requirements, and reduced deacclimation rates.


Nov 13NGRA-ARS Sensor Technology Workshop 
Held in Sacramento, CA, nearly 30 scientists (including Cornell scientists Terry Bates and Katie Gold) will present their work developing sensor technologies for vine status and management, data integration, and modeling applications.
