Abstract
The United States is a global leader of blueberry production, second only to China in total production by country.
About 44% of US blueberries are grown in the Pacific Northwest (PNW). Diseases are a limiting factor in blueberry production, with viral diseases playing a major role in crop decline.
Mixed infection of viruses in blueberries is not well understood but may play an important role in disease expression.
A total of 2,735 samples were collected in the PNW from the blueberry germplasm repository, industry plots, breeding programs, and university research fields for the purpose of screening for viruses known to the region and viruses recently characterized.
The viruses screened for included: blueberry shock virus (BlShV), blueberry scorch virus, blueberry virus L, blueberry mitovirus 1, blueberry latent virus, blueberry virus M, and blueberry virus S. The prevalence and distribution of each of the viruses as well as a statistical breakdown of viruses detected in symptomatic plants is reported.
Among all samples tested, BlShV was found in the highest incidence and distribution.
Among samples collected from symptomatic plants, BlShV was found in the highest incidence, detected in 84% of the symptomatic samples.
Approximately half of all symptomatic plants infected with BlShV were detected in mixed infection.
