Economic benefits of disease prevention in young vineyards.

This is a presentation about some of the progress we’ve made on the economic benefits of adoption of preventative practices in young vineyards years before trunk disease symptoms might appear in the vineyard. We set out to determine whether growers might benefit from using these practices in young and mature vineyards.

Economic Hurdles to Adoption

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.

Identify the socioeconomic hurdles to adoption

  By ,

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.
