Rohslausen discusses how cell wall chemical composition and differences in wood anatomy could be responsible for variance in susceptibility between different cultivars.

Kaplan reports on an economic model, for adoption of practices and, for prevention of trunk disease pathogens. This report discusses economic cost and payback time of these management adoptions, based on reducing yield loss and cost of implementing preventative practices.

Mizuho Nita, and Sabrina Hartley
Progress update on development of web and mobile diagnostic application that will enable growers to properly diagnose trunk vine diseases and in return help determine proper management practices for the specific trunk disease identified.

-Possible pathogen detection tools for growers.
-Evaluate and improve culture and molecular detection methods.
-Promote preventative practices to minimize pruning wound infections.
-Develop prediction models to improve decision making processes for pruning times and possible treatments.

This research is a broad effort to understand grower decision making in the context of trunk disease management.” A presentation on a research survey to identify hurdles in which farm managers, consultants, and the like, face when adoption of new management practices may be necessary.

Renaud Travadon & Kendra Baumgartner
Developing rapid grapevine screening process to identify wine and table grape cultivars for resistance to Eutypa Dieback based on foliar and woody symptoms. Future efforts towards comparing gene expression profile between previously characterized resistance and susceptible cultivars.
Based on previously discovered Phomopsis resistant genes, determine if woody tissue resistant genes can be linked to green tissue symptom expression.
Determine how anatomical and chemical differences effect Botryosphaeria resistance levels in 7 table grape cultivars.
