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.

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.

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.

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.

Goal – Increase early adoption of preventative practices.
Activities – Surveyed growers on usage of three practices and developed an economic model to predict cumulative returns (ie profits) when adopted early (year 3) vs. late (year 10).
Results and Outputs – Despite low efficacy of late adoption, >50% of growers adopt practices after year 8. Why? Profits are low in year 3, and the cost of preventative practices seems relatively high, esp. because trunk diseases are not yet serious. Regardless, early adoption (not late adoption) increases profits in the long term.
Significant Outcomes & Impacts – Reducing uncertainty about economic benefits in the long term will increase adoption of preventative practices in young vineyards.
