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.

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.

Goal 2 – Accurate identification of trunk fungi
Activities – Allow for proper disease management and control practices
Results & Outputs – Developed a comprehensive DNA sequence database of trunk inhabiting fungi
Significant Outcomes & Impacts – Accurate species identification will lead to proper disease management practices.
Goal – Develop visual diagnostic aids for trunk diseases.
Activities—Create a web/mobile application and website for trunk disease diagnosis.
Results & Outputs
Developed beta-versions of logic and flow charts.
Significant Outcomes & Impacts
Accurate disease diagnosis will minimize losses by leading growers to proper management practices.
