Research Project: An Economic Analysis of Virus Infections in Raspberry Production

Location: Horticultural Crops Research

2013 Annual Report


1a.Objectives (from AD-416):
Extrapolate cost and yield data from existing research plots to commercial scale raspberry production operation.


1b.Approach (from AD-416):
A short-term cash flow analysis on planting establishment and a Net Present Value (NPV) analysis will be used to calculate the future returns and cash flows for different scenarios, for the establishment period and the life of the planting. The difference between each scenario’s NPV per acre and the baseline scenario (the virus-free planting) is the value the growers receive from the use of virus-free raspberry nursery stock plants. Baseline data on planting costs, revenues, and financial assumptions will come from studies compiled and published through universities and current research planting and used to compute the NPVs.


3.Progress Report:

This research was conducted in support of NP 303 objective 1A of the parent project. Research on this project has focused on mixed virus infections in red raspberry in the Pacific Northwest and how each virus in the mixed infection contributes to severe crumbly fruit and reduced plant growth. The first stage of the project focused on the three most common viruses, Raspberry bushy dwarf, Raspberry leaf mottle and Raspberry latent viruses and the interactions between these three viruses in causing crumbly fruit. The data from the projects is now being used to develop an economic analysis on the impact of each virus and virus combination on profitability and to quantify the benefits of using virus-tested plant material for establishing new raspberry fields. In addition to fruit quality and yield, the analysis includes the cost of harvesting, which based on grower input, is impacted significantly by the level of crumbly fruit. Data on fruit yield and quality from USDA-ARS along with data from Oregon State University is being used to determine the cost of ‘clean’ plants, replanting a field, life expectancy of a field, and cost of insect control to reduce virus movement into new fields.
