Management of Measles/Wood Canker Diseases in Table Grape Production

This survey will only take 10 min.

The focus of this project is to evaluate the impact that measles (a.k.a esca) and other wood diseases (bot canker, eutypa dieback) have on table grape production, determine the current management strategies for these diseases and identify management approaches that might be implemented in the future.

The data provided will be kept confidential by coding all the information provided prior to sharing the data with the table grape industry and allied industries.
