Mobile diagnostic aid application development

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.

Identify the socioeconomic hurdles to adoption

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).

2.1 2.2 2.3

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.2.4

Significant Outcomes & Impacts – Reducing uncertainty about economic benefits in the long term will increase adoption of preventative practices in young vineyards.
